Scheme of connecting a deep pump through a capacitor. Types of surface pumps. Features of installation for other water supply systems
Connecting the pumping station to the well allows solving the problem of supplying water to private houses outside the city and inside the city limits. Such an operation is easy to carry out with your own hands. And we will tell you how to do it.
1
If there is no centralized water supply in your dacha or in a private house, this does not mean that you have to carry water in buckets. A similar problem today is solved very simply - through the arrangement of wells. Their depth can be different. Everything depends on how far from the surface of the earth lies aquifer. To create the pressure in the private water supply network necessary for the operation of sanitary facilities and appliances on a permanent basis, special well equipment is used - pumping stations.
Different versions of pumping stations
They provide uninterrupted lifting of water from wells up to 20 m deep. In addition, such equipment distributes (evenly) raised liquid between all points of its consumption in the dwelling. As a result, a private house constantly provided with water. At least, as long as there is electricity (pumps function from electricity). But even in situations where there are irregularities in your area electric power, you will not be left without water from the well. Solve this problem by small power plants or special generators of compact size.

The installation and connection of a domestic pumping station is performed only in cases when drilling is not more than 20 m deep. If the aquifers are buried in the ground below, there will be no sense from the compact pump. In such situations, a special deep-water pump should be installed. When selecting the equipment we are interested in, we should pay attention to its technical parameters and operating modes, and not just the cost of the pumping station. First of all, you need to determine the type of suction pipeline.
Pumping station
It happens:
- ejector (in other words - two-tube);
- single-tube.
Stations with one pipe are very simple in their construction. In them, fluid from the well enters the body of the pumping equipment used on the only available line. Installation of such an assembly with their own hands is done without problems, and quickly enough. Pumps with two pipes are more structurally more complex device. But the efficiency of its operation is several times higher and more reliable than single-pipe equipment.
In the ejector pumping station, the water is raised by a vacuum created by a special wheel. It is initially installed in the unit. The increase in the rarefaction is due to the inertia of the fluid circulating when the equipment is switched on. Due to this scheme, pumps with two pipes are always characterized by low power, while possessing a large indicator of usefulness. They are capable of lifting liquid from great depths. Therefore, the installation of a two-pipe pumping station is recommended for depths of 10-20 m. If the depth of the well is less than 10 m, safely place equipment with one line. It will fully cope with its tasks.

To connect the pumping equipment yourself did not cause you serious difficulties, it is desirable to know in advance its design and understand the principle of its functioning.
Connected pumping station
Here everything is not so difficult. The main elements of the pumping station are as follows:
- Centrifugal pump. The basis of the whole construction. It is responsible for directly lifting fluid from the well, as well as for its supply to the residential building.
- Electric motor. It is connected to the pump and to a special pressure switch. The latter is of great importance for the normal operation of all equipment. The relay starts the engine when the pressure in the system decreases and turns off the motor when an excess of load is fixed.
- Hydraulic accumulator. This node is assembled from two separate parts. They are separated from one another by a special membrane. The only task of the battery is to smooth out the water hammering that occurs during the operation of the pumping station.
- Water intake element. This part of the equipment must be provided with a check valve. It is located directly in the well.
- The manometer. It monitors the pressure in the system and transmits data to the relay, which turns on / off the pump.
Also, the described equipment for water withdrawal from the well is equipped with a highway. It connects a pump and a water intake into one system. The cost of the stations we consider for installation on a well depends on the quality of all the nodes described above, on the capacity of the equipment (it can be 1.5 cubic meters of water per hour and 5), on the maximum head and power of the unit. Also, the price of the pump is affected by the promotion of the firm that produces it.

Specialists recommend installing water withdrawal equipment in a separate building from the house. It is advisable that it is at some distance from the dwelling, since during operation the pump produces enough loud noises. They can stop sleeping at home. The room for installing the equipment must be dry. Recall that the unit is powered by electricity. So, the increased humidity has a damaging effect on the pump. Servicing equipment under such conditions is life-threatening.
Pumping station in the place designated for it
The station should be installed on a special pedestal made of blocks of wood or bricks. The unit can also be placed on a strong, well-leveled concrete base. Under the pump, a suitable mat is made of rubber. It will protect you from possible electric shock, as well as dampen the vibrations that occur when starting and operating the unit. The station, in addition, needs to be attached to a concrete (brick, wooden) base. Anchor is used for these purposes. They are installed in the legs of the pump, which are initially available in equipment from all manufacturers.
If the water intake equipment can not be placed in a separate building, it can be installed in a basement. But in such situations it is necessary to select models of pumps that produce a minimum of noise during operation.
5
There are two exits on the pumping equipment. They allow to make its connection to the water supply of the dwelling and directly to the point of water intake (in our case - to the well). First you need to connect the station to the well. This is done with a 32-mm. One of its ends you connect to the pump, and the second you plunge into the well. It is desirable to produce a thermal insulation of the pipe product using a good insulation. Suitable products under the brand Thermoflex.
Station operation after connection
At the end of the pipe, which is immersed in the source of water intake, it is necessary to mount coarse filter cleaning. Its function is performed by a thin metal grid. From above put check valve. It will ensure a constant filling of the tubular product with water. If there is no liquid in the pipe, the station will not be able to pump it out of the well. The metal filter and the valve are fixed with a coupling having an external thread. Similar fasteners are also used for mounting the second end of the pipe. The fastening scheme in this case looks like this: connect an American (tap) to the pump outlet, then put the coupling and connect it with a collet device with a plastic tubing. All works are done by themselves without any difficulty.
The next step is to connect the equipment to the water supply. For these purposes, there is a special entrance to the station (at the top of it). To it first connect (on a carving) the crane-American, and after that screw in a 32-millimeter combined clutch (usually polypropylene). Be sure to solder the coupling and the pipe. Then their connection will be really strong. You have connected all the elements of the pumping station. You can run it and enjoy the uninterrupted supply of water to your home from the well!
To provide a house and a plot, you can use a wide variety of modern techniques. Very often surface pumps for cottages are an ideal choice. They are relatively inexpensive, easy to install and operate. Servicing or repairing a pump on the surface is easier and more convenient than a submersible model.
Surface pumps, as the name suggests, is installed on the surface. These are relatively inexpensive and quite reliable devices, although for very deep wells they are not suitable.
Rarely will you find a surface pump that can supply water from a depth of more than 10 meters. And this is only if there is an ejector, without it the indicators are even lower.
Surface pumping stations have a wide range of applications, they pump water from various sources with a depth of no more than 10 m
If the dacha has a well or a well of suitable depth, you can safely choose a surface pump for the site. You can take a model with a relatively low productivity for watering or a more powerful device that will effectively provide water to a private house. The convenience of surface pumps is obvious: first of all, it is free access for adjustment, maintenance and repair.
In addition, the installation of such a pump at first glance looks very simple. The pump must be installed in a suitable place, lower the hose into the water, and then connect the device to the power supply. If the pump is only needed for watering, you can purchase and install it without any additional elements.

To optimize the operation of the device it is recommended to take care of the device for automated control. Such systems can shut down the pump when a hazardous situation occurs, for example, if there is no water in it. "Dry running" is not recommended for almost all models of surface pumps. It is also possible to automate the shutdown of the pump, if the watering time is over, the required volume is filled, etc.
How is the pumping station
To organize an autonomous water supply from a well or well, it is worthwhile to purchase additional elements and combine them into a full-scale pumping station. In addition to the pump, you will need a hydraulic tank, as well as a pressure switch. This relay turns the pump on and off, depending on whether the tank is empty or full.
The scheme demonstrates the detailed order of water supply to a private house from a well using surface pump in the pumping station (+)
As a result, there will always be some water in the house, and the pump will be completely empty. This greatly extends the resource of its work. In addition, the presence of a hydraulic tank compensates for possible water hammers, which positively affects the condition of the water pipe as a whole.
In addition, it is also recommended to purchase a manometer (if the tank is not equipped with a hydraulic tank). Of course, you can buy a pumping station, complete with all the necessary components. The procedure for installing an industrial production station and assembled independently is not too different.
Surface pumps are often used in the pump station together with a pressure accumulator and a pressure switch that is automated for the operation of this set of devices
The hydraulic accumulator or the tank is a container equipped with a special rubber membrane. As the tank is filled, this membrane stretches, and when it is emptied, it contracts. Such a device is considered highly efficient for autonomous water supply.
System with a storage tank
As an alternative to the accumulator, one can consider an ordinary tank, for example, plastic. It can be any suitable capacity that will meet the needs of the family in the water. Typically, such a storage tank is installed as high as possible to ensure sufficient water pressure in the water supply system at home.
In this case, it is necessary to take into account that the load on the walls and floors will increase. For calculations it is necessary to remember not only the weight of the accumulated liquid (the weight of water in the tank of 200 liters is, of course, 200 kg). Take into account the weight of the tank itself. The cumulative weight is related to the bearing capacity of the house. If there are any doubts in this respect, it is better to seek the advice of an experienced engineer.

To automate the operation of the pump with a self-contained storage tank, you can use a float sensor. This is a relatively simple device, many craftsmen make it themselves. A float is installed in the tank, with which information about the water level comes to the automatic switch.
When the amount of water in the tank reaches the minimum level, the pump starts and runs until the tank is full. After that the pump is automatically switched off. The storage tank is considered an economical variant of the house's water supply, since the cost of such a complex of devices is lower than that of an industrial pumping station.
The surface pump at the dacha can be used for various purposes, for example, for filling water with a storage tank, for irrigation, etc.
Where to install the pump
The most important moment when installing a surface pump or pumping station is the choice suitable place. Here are a few requirements that will help you find the right place for pumping equipment:
- the closer the device is to the source of water, the more steadily its fence will be carried out;
- the device (or a set of devices) should be sheltered from bad weather in a special room, a bunker, etc.
- it is necessary to protect the pump from freezing during winter colds;
- the place where the equipment is installed must be ventilated to avoid an elevated level of humidity causing corrosive processes;
- should take care of sufficient space not only to accommodate the pump or the entire station, but also to carry out the necessary maintenance, adjustment, repair, etc .;
- the place should be either removed from the living quarters, or additionally isolated from noise, as the surface pump technology operates quite loudly.
It is not always possible to comply with all these conditions, but this should be pursued with all the strength. Surface pump is usually installed as close as possible to the water source.
Due to the insignificant suction depth, on average 8 to 10 m, deep pumps are recommended to be installed at the shortest distance from the water source
To protect the device from external factors, it can be put in places like:
- special wooden box;
- well-arranged well head;
- a cavity excavated in the earth;
- inside a spacious well;
- the boiler room located next to the water source and the like.
Of course, each site is individual, the decision must be made depending on the situation. In the ground the pump is deepened, if it is necessary to protect the device from frost, but there are no other options. It will be necessary to dig a fairly large and deep pit, it should be below the freezing level of the ground.
Of course, if the dacha is used only in the warm season, the requirements for installing the pump may not be as severe. The freezing problem automatically disappears. But the pump should still be reliably hidden from the precipitation. If the dacha is to be kept for the winter period, of course, the surface pump must be removed, cleaned and stored in suitable conditions.
If it is decided to install a surface pump or a pumping station in the basement, make sure that it does not freeze during frosts
If the water source is a well of sufficiently large diameter concrete rings, you can place the pump directly in it. In this case, you do not need to dig anything, you need a small solid raft, able to withstand the weight of the pump. The raft is lowered directly to the surface of the water mirror, on top of which the pump is fixed.
The advantage of this solution is that the depth of immersion of the hose will be somewhat increased, i.e. The fence will be made from a greater depth. But it is necessary to take into account possible problems. For maintenance and repair of equipment it will have to be removed to the surface. The risk of contact of the appliance with water increases. But in general this option is quite acceptable.
If it is necessary to install a surface pump in the pump station, the requirements for choosing the suitable location will be approximately the same. Although it should be remembered that the size of the whole set of devices is slightly larger than that of a conventional pump. Most often, the station is put in a special caisson, which is equipped near the well.
A convenient place to install a surface pump is a boiler room: usually in this room is already arranged a good sound and heat insulation
An ideal place is a boiler house, already well-equipped for the operation of heating equipment. Install pumping stations and in the basement of a residential building, but such a room will have to be carefully prepared: insulate and provide heating to prevent freezing of water, etc.
You can put the station inside the well, but this will cause an additional problem. To adjust the pressure switch, the equipment must be removed to the surface. Indicators that are obtained when the pump on the surface, can change when it is lowered down. This makes it difficult to adjust the pressure switch.
This diagram clearly demonstrates the procedure for calculating the maximum immersion of a surface pump hose. It is necessary to take into account the distance separating the water mirror and the level of the water supply, as well as the space between the water source and the pump equipment (+)
In the absence of the best, surface pumps are sometimes placed directly in living quarters: in the hallway, in the storeroom, in the bathroom, etc. So the equipment will not get wet and will not freeze, but the noise from its work will definitely interfere with the tenants of the house. This option can be considered only as a temporary one, at the first opportunity, the pump or station should be installed in a more suitable place.
Select the location for the surface pump should be before it is purchased. When installing such equipment, you should adhere to the rule "1: 4". This should be the ratio of the depth from which water is drawn to the horizontal distance to the pump.
If water comes from a depth of two meters, then the horizontal section to the equipment should be no more than eight meters. If this ratio is not met, for example, the distance to the pump is longer, it is recommended to take the pipes a quarter of an inch wider than the manufacturer's recommended dimensions.

Pump connection procedure
Although it is believed that with the installation of surface pumps, the hassle is less than when installing submersible models, still it is not necessary to treat this case lightly. A number of important points taken into account when installing the pump will help improve the efficiency of its operation and prevent possible breakdowns.

Preparation of materials and tools
To connect a surface pump, you need to stock up with the appropriate materials first. Here is an approximate list of required elements:
- a connecting pipe that is installed between the pump and the hose;
- a hose for water intake from the source;
- hose or pipes to connect the pump to the storage tank;
- hose for irrigation;
- check valve with screen filter;
- a special adapter for the second output;
- connecting fittings;
- fasteners and the like.
If a system with a hydraulic accumulator is installed, a pressure switch and a pressure gauge are also required. If it is decided to use only a storage tank, you should purchase or make a float sensor. The tool may need different keys, as well as devices for working with fasteners. Roulette, a building level, materials for insulation of threaded connections, a soldering iron for polypropylene water pipes, etc. are useful.
Installing the device based on
Before you connect any elements to the pump, you need to install it on a firm and level surface. This is an important point. Even a small instability or roll can cause a significant decrease in the productivity of the device. The base can be made of concrete, brick or even from solid wood.
To install a surface pump, you first need to find a solid and even foundation. It can be made of brick, wood, concrete or, as in this case, use metal brackets
The main thing is that it is firm and even. In order to secure the pump in a stable position, anchor bolts are usually used. Under the fasteners in the case of the device there are special holes. Sometimes a large rubber gasket is mounted under the pump casing. It acts as a shock absorber and dampens vibration when the engine is running.
Feed hose with check valve
After that, the supply hose must be installed. A check valve is attached to its lower part, onto which a strainer is fitted. As a fastener, use a clutch with an external threaded connection. Pumps equipped with a check valve and a filter coarse cleaning, are produced in industrial enterprises. In order not to bother with this part of the system installation, you can buy such a ready-made hose.
But, according to the experienced masters, independent manufacture The hose with the valve will cost much less. If the installation technology of all elements is met, such a device will be no less reliable than the model of industrial production. Sometimes two non-return valves are mounted: one at the end of the hose, the other near the accumulator.
The upper part of the hose is connected with a pump by means of a fitting. Instead of a hose, you can use polypropylene water pipe with a diameter of 32 mm. After this, the hose is lowered into the water in such a way that the check valve is immersed in it no less than 30 cm.
To connect a non-return valve to a system with a surface pump, it is necessary to use special fittings and adapters, for example, as shown in the photo (+)
The non-return valve, as well as the filter protecting it, are necessary elements. The valve protects the pump from idling because it prevents water from pouring back after the pump is turned off. The filter is necessary to protect the device from contamination.
Connection to the water supply system
Then connect the pump to the accumulator tank or accumulator tank. It should be remembered that the horizontal part of the hose should have a slight slope. Often, the flexible connection to the tank and adapter, as well as other elements of the system are mounted on threaded connections. In this case, care must be taken to ensure proper sealing with FUM tape or other suitable seals.
After that, the storage tank or station is connected to the water supply system at home. When laying pipes, you should also remember the correct gradient. An important point is the insulation of pipes laid in the ground. Today there is a wide choice of suitable heaters, it remains only to choose and use the suitable one.
To install a part of the water pipe that joins the pump station, you will need a set of fittings, PVC pipes, as well as a special device for soldering these pipes
Only after all the devices are assembled in a common highway and connected to the inside of the house water pipeline, you can test the operation of the system. Incorrect start of the surface pump can lead to its rapid breakdown. The details of this process are set out in the manufacturer's instructions, which should be carefully studied.
Checking system operation
Usually, before starting, surface pumps are filled with water through a special hole. The water must fill not only the pump, but also the parts of the pipeline before and after the pump. Then fill the filler hole. It is recommended to immediately record the pressure readings in the accumulator and in the system.
Before installation, the surface pump must be filled with water through a special filler hole. Do not include such a pump in the "dry run" mode
This information can be useful when further configuring the system. Perhaps you need a little pumping air into the tank or blew it. After that, the pump is connected to the mains and switched on so that the storage tank or accumulator is filled with water. Immediately check all connections for leaks and troubleshoot if necessary.
If you use a self-made tank, it will not hurt to check its integrity. Through undetected cracks, water may leak. This problem should also be solved immediately. If the system is assembled correctly, and nothing flows anywhere, it remains only to configure the control equipment.
After this, you need to check the operation of automatic systems. To do this, you need to open the water and observe the process. When the drive is emptied, the pump must turn on in automatic mode and turn off again when the capacity is full.
Normally, the pump automatically turns off when the pressure in the system approaches the three-atmosphere index. After this, the water is drained off until the pump starts to work again. At this point, you should record the actual pressure in the system and compare it with the manufacturer's recommendations. If significant differences are found, it is necessary to adjust the operation of all devices to an acceptable level. After configuration, the check is performed again.
Videos on surface pumps
Details on how to properly connect a surface pump in the pump station are described in the following video:
Here is clearly shown the order of connection of the surface pump for irrigation:
There are not so many "pitfalls" in installing a surface pump. Of course, do not rely on your own flair or the famous "maybe". A careful study of the manufacturer's instructions, as well as a few small consultations with experienced masters, will help even a novice to cope with this task quite satisfactorily.
Arrangement of water supply and sewerage in a private house is a question though beaten up, but actual for the majority. Accustomed to the benefits of civilization, we can no longer imagine a full life without them. At the water supply and sewerage system, comfortable living in a private house is now completely tied up. At the same time to carry water buckets constantly - hard and exhausting work. Why talk about trying to take a bath in such Spartan conditions! But, fortunately, now solve the problem with the supply of water into the house simply - just install the pump. A selection, installation and connection of the surface pump are discussed in detail in this material.
Why is it needed?
The name of the surface pump speaks for itself - this device for proper functioning does not require immersion in water. It is installed "on land", and the liquid is fed into the pipes with a flexible hose coming from the pump into the water. Due to easy access to the device, the surface pump is easy to maintain, which attracts owners of private houses.
On a note! Such installations are rather weak and can not lift water from and large depths. The maximum is only about 10 m. If the well is on the site deeper, then the pump will have to buy a more powerful one - for example, a submersible pump.
Surface pump, in addition to water supply to the cottage, can also be used for watering a garden site or pumping water from the basement, which is important for areas with frequent flooding in the spring.
The usual surface pump works as follows: at the end of the suction conduit, which is not lowered into water, a vacuum is created, and the liquid begins to rise through the hose due to the difference in the pressure indices at both ends of it. It is interesting that at the suction site this figure is 760 mm Hg. Art. at full vacuum and, replacing mercury with water, we will get a height of 10.3 m. So it turns out that under full vacuum the liquid can only rise by this amount. It should also be taken into account and the presence of certain losses in the friction against the walls of the waterway - thus, we get a distance of only about 9 m. As a result, the actual working height of the surface pump is quite small - about 8-9 m.
When choosing a pump, it is also important to consider the distance from the well to the pump itself, as well as the position of the water conduit. That is, it is worth remembering that the 4 m horizontal part of the hose will be equivalent to 1 m of water lifting.
The surface pump operates as follows.
- or the accumulator connected to the pump, due to the construction, will be filled with water to a certain point.
- The automation of the pump will shut it down after reaching a certain level of water. The water supply will stop.
- When the water from the tank is exhausted, the pump will automatically turn on again and refill the accumulator completely, then stop.
If you need to pump water from a shallow well or a nearby pond, the purchase of a surface pump will be the best option organization of autonomous water supply to the house. In this case, such a device is installed very simply and does not need special operating conditions.
Advantages and disadvantages
What else is good for surface pumps? The advantages of these devices are the following.
- Small size - such a pump can be installed almost anywhere, it will not interfere with anyone, does not require the creation of a massive foundation.
- Cheapness - you can buy such a pump for little money.
- The period of uninterrupted operation is about 5 years - this is a decent working time for such a device. If you handle the installation carefully, it will last longer.
- Payback of equipment is fast - a maximum of two years.
- Installation of such a pump is simple, carried out quickly. The only difficulty is the need to securely attach cables and hoses to it.
- The device sparingly - does not spend a lot of electricity.
- Shutdown in case of need occurs automatically - no need to guard the operating device.
- In repair, as in operation, the surface pump is very simple and cheap. Yes, and convenient - even a hose from the water does not need to get.
- Security is another advantage of the installation. The electrical cable in the device does not come into contact with water.
But the pump installed on the surface, there are some drawbacks, which you should know in order to assess the need to purchase this equipment and the justification of monetary costs.
- Low power - such a device will be able to raise water only from a depth of not more than 8-10 m.
- You must install filters.
- Before switching on the pump, it must be pre-filled with water.
- The equipment creates a lot of noise, so it is not recommended to install it in the residential area of the house.
- Use a surface pump only in a warm room.
The advantages of the equipment, as we see, are greater than the disadvantages. The main thing is that the minuses are not the determining factors, and then you can safely buy this equipment.
Centrifugal surface pump "Aquarius BC-1,2-1,8U1.1"
Types of surface pumps
Pumps surface are of three types - centrifugal, ejector and vortex. They differ from each other in design features and performance.
Table. Types of surface pumps.
| Type of equipment | Characteristic |
|---|---|
| Inside the body of such a pump is a special axis, on it is fixed the so-called impeller, on which the blades are located. It is they who will transmit energy to the water during the rotation of the main axis. This is a small installation, they are inexpensive. The suction depth is small, so they are often used not for pumping water into the hydraulic accumulator, but for adjusting the pressure in the water supply system, watering, pumping water from the basement during floods in the spring. Efficiency - only about 45%. Not recommended for use as a pump for filling accumulators. |
| Such a pump is also called self-priming, and inside it has special wheels that create the necessary pressure during the operation of the device. They rotate due to the operating shaft, supported by bearings. The power is higher than that of a vortex pump, and therefore it can be pumped from a greater depth and can be used to organize a water supply system for a residential building. This is more expensive, but at the same time reliable and robust type of device with an efficiency of up to 92%. Can be used to create a pumping station in the house. |
| Such a pump consists of two circulation circuits: in one of them the liquid is supplied to the ejector, where a pressure difference is created due to the Bernoulli effect, and water comes from the second circuit. This design allows you to lower the pump to a depth, which will solve the problem with a low suction height. But recently such units are not in demand, as there are more efficient submersible pumps. |
Based on the above written, it can be noted that it is best to acquire centrifugal pump. This is the best option. We will become acquainted with its device closer: a pair of disks is installed on the gearbox shaft inside the mechanism. In one of them a small hole is made, connected with the free space between these parts. In this gap there are plates inclined at a certain angle - they create a special tubule from the center of the free space to the edge. These "strokes" are connected to a diffuser connected, in turn, to a supply conduit. And the suction hose is connected to the disk hole.
The interdisk free space and the suction hose are filled with water, then the reducer is started, and the blade plates begin to rotate and push out the water. This process is due to centrifugal force. As a result, a depleted space is created in the center, and at the edges and in the diffuser, on the contrary, the pressure rises. To equalize this "bias", the system will seek to level indicators and begin to pump water. So this installation works.
Attention! Independently, such pumps are usually not used - they are part of the design of the pumping station. This system includes a control unit and a hydraulic accumulator.
To pump served as long as possible, create. The unit pumps the water as necessary into the storage tank. This allows significant savings in equipment resources, since the pump will only turn on as the accumulator is empty. In addition, the frequent activation of a pumping unit entails a great deal of energy. And thanks to the arrangement of the pumping station, it is possible to save resources, money and provide the house with a certain supply of water.
A hydraulic accumulator as part of a pumping unit is a volumetric tank having inside a membrane or a pear around which there is a certain pressure level. That is, the water that enters this tank is under pressure. The design of the pumping station also includes a pressure switch, which will just cause the equipment to be started and shut down in time. And behind the level of pressure will help keep track of the manometer installed in the system. Connects all the details into a single organism "five-out" - a special choke with five outputs.
Pumping station with integrated ejector
How to choose?
How to choose a surface pump? To begin with, it is necessary to get acquainted with certain criteria, knowing and evaluating which, the choice will be easy.
It is worth remembering that for the organization of an autonomous water supply system at home you should buy a pump more powerful than for a simple watering of the greenhouse. Therefore, it is important to clearly know for what purposes the equipment is purchased.
Calculator for calculating the required capacity of the pumping station
Happy owners of cottages and individual houses perfectly understand that the level of comfort of their homes depends on the successful solution of the problem of water supply. Spoiled by civilization, people hardly want to go to the well or the river regularly with a bucket. If there is no possibility to connect to centralized system water supply, it is necessary to equip the autonomous. Most often a hole is drilled on the site. Her work must be properly organized, otherwise problems can not be avoided. Mounting the water pump in the well - the most important stage its arrangement. How to do everything correctly? Let's understand.
Preliminary work
It is important to choose the right pump. The equipment must fully comply with the well in size. The difference in the diameters of the casing and the pump will lead to serious problems in the operation of the equipment, up to its damage. For example, with a large gap, the pump will not be able to provide enough water to fully cool the engine, which can simply burn.
In the documents for the equipment, all the minimum values are indicated. They must be taken into account. One more nuance. In the sections of the joints of the casing pipes, their diameter decreases slightly, despite this the pump must freely pass into the well. Forced pushing the mechanism is unacceptable. Before installing the pump in the well, it is worth checking the casing for possible irregularities, constrictions or distortions. Detected defects must be eliminated, otherwise they seriously hinder the installation of equipment and its operation.
Installation of the submersible pump in the well step by step
When starting the installation of submersible equipment, it must be remembered that it is intended for operation under water. This makes special demands on waterproofing the system. It is important to perform all connections as accurately and qualitatively as possible.
The procedure for installing the pump includes several basic steps
Preparing the pump and pipes
First of all, you need to install a nipple or adapter on the pump, to which we will subsequently attach the pipes. The nipple will provide us with a transition from the internal thread to the outer thread. For some pump models, such an adapter is included in the sales package. If there is no nipple, it must be purchased. And it is best to do this simultaneously with the purchase of the pump, so it will be easier to choose the correct adapter.
When installing a nipple, a threaded connection will be required. For better sealing, it is performed with a winding. Plumbers usually use a patch or a taped tape. In this case, it is better to refuse both options. Optimal choice - Tangit tape or linen. When working with flax, do not forget to treat the joint with a silicone sealant or similar formulation. Such a connection will be stable not only to internal pressure, but also to possible hydraulic impacts.
We wind the coupling on the nipple. We start to prepare pipes. They can be metal or polypropylene. In any case, experts recommend using products with a diameter of at least 32 mm. Narrow pipes significantly limit the water pressure, which will adversely affect the operation of the pump. Maximum equalize the prepared pipe section. This is necessary to ensure that it enters the well as smoothly as possible, without distortion. We connect the pipe to the pump.
Connecting the power cable
Before starting the installation of a downhole pump, it is necessary to ensure its power supply. To do this, connect the power cable. It may be part of the pump, or it may not be available. In the second case, you need to consult an electrician and purchase a suitable cable. To the electrical terminals of the motor we attach the prepared cable. It is necessary to isolate the connection points with special heat shrink tubes, we install a shrink sleeve on top. So we will provide the most reliable waterproofing.
Preparation of the suspension system
The power cable connected to the pump is laid along the pipe. Now we need to fix borehole pump rope so that you can lower it down. It is best to take a metal cable, but a strong nylon cord will do. Securely fasten it to the body using special mounting lugs. Fix the attached cable along the cable and pipe. We have obtained a "route" of three elements, which must be fixed among themselves. Optimum use for this purpose special clamps, but the tape or wire is quite suitable.
The device in the well is lowered smoothly, without touching the casing wall equipment
Lowering the pump
To the base plate above the bore hole we fix the upper end of the pipeline, install a check valve if it is not present on the pump, a knee, a latch and a manometer. After that we connect all devices to the water supply system. Prepared suspension system attached to the crossbar, now you can lower it. To properly install the pump into the well, it is necessary to ensure its smooth descent into the casing. The mechanism should not touch its walls, if this is not possible, it is necessary to protect the body with a rubber ring.
Mounting the water pump in the well is a complicated procedure. Even a minor error can lead to problems in the operation of an autonomous water pipe and damage to equipment. Lusche entrust the procedure to specialists who know exactly how to install the pump in the well. They will quickly and accurately carry out the installation of equipment and give a guarantee for its uninterrupted operation.
Video: installing the pump
Take an interest in the opinion of any person, especially those living in the country, about the immediate problem that was solved immediately. Light, water, heating are the three components, probably made by yourself, to enjoy the beautiful view from the window and the fresh air of the countryside.
Accustomed to the comfort of the townspeople, they will not walk with buckets on the rocker or without it to the well, like villagers, but will seek a solution to the problem. Connection to the well of a pump based on a well or a well is a solution to the problem of water supply.
If there is a well on the site the best option serves as a surface pump, easy to connect and maintain, the price of which can suit many consumers. Pumping station will help to provide kitchen, bath, kitchen garden with water from the well.
Separation of pumps by types and characteristics
The pump is selected after the completion of drilling operations and obtaining that the selected pump type corresponds to the parameters of the well. All water pumps are divided into 2 groups, and from the name it becomes clear which one is where.
Surface on the surface, or from above, deep (submersible) in depth:
- Surface pumps in the photo take up the liquid by suction, and this limits the breadth of their use in the wells.
- The depth of the water rise does not exceed 9 meters and the positive temperature regime must be observed. Water from great depths these models are not adapted to deliver upward.
- Another principle underlies submersible pumps for wells. They fall 2 meters below the water level to push it to the surface of the system.
The depth of occurrence of water in the well is completely irrelevant. The models are calculated by the height of the rising water flow. For example, you can take the simplest system, which copes with the height of the rise of water by 40 meters.
Any private house can be fully provided with such a system, and in fact there are pumps that manage from 80 m height.
Attention: The depth of a deep system is only the complexity of its maintenance.
- The type of electric motor and the power of the model determine the performance of the system.
- The deep system kit should contain automation to protect against overheating or dry running.
- are divided into 3 types. Vibration Pumps in the construction market are presented in sufficient numbers and with different names, but the preference should be given to those that have a thermal switch, and the water intake is carried out by the lower part.
Vibration of the operating mechanism provokes a gradual destruction of the well. The sludge can get into the pump, it is important to lift it when the engine is running. The minus of these designs is a lot of problems in the process of operation. - A universal system, as the video in this article shows, is a centrifugal pump for wells. The work is based on the movement of wheels and blades.
The space is filled with fluid between the blades, it, in turn, is fed upward by a centrifugal force. Quality with value are in agreement, so they are in demand by consumers. - The attached instructions to the pump model will help you to choose the right type for functionality and other parameters.
- Owners of holiday cottages without the presence of electric grids in the vicinity, can acquire a system with a manual drive, as people say, just put a roll. They are piston and rod, are easy to operate, cheap cost, but to raise the water you need to put physical effort, which refers to the minus of this system.
In order to properly connect the surface pump to the well, it is important to know a few nuances and then the pump will fully perform the intended functions.
So:
- How to connect an agidel pump to a well in order to permanently forget about the problems with water supply? The pump is installed at a distance as close as possible to the well.
The chosen place should be well ventilated and with a positive temperature. The pump is fixed to a flat surface to prevent it from moving during vibration generated during operation.
The best option for placing the pump is the caisson (see), a special recess covered by a lid, and still lockable from curious and nascent children. Pipes departing from the pump to the points of analysis are buried in the ground below the freezing point, then the winter is not terrible for the owners and they do not depend on the problems of the central water supply.
The "Agidel M" pump belongs to the summer version of the models, it is used for watering lawns, beds and water supply of the bath. To install it, a well-tamped, flat and level platform is enough. - Experts should be engaged in connecting the electrical equipment, but if the decision is made to perform the work independently, then again it is necessary to check and verify the conformity technical specifications pump and mains. Fill with safety devices, install them, take care of grounding
- Start the pump after filling the body with water, through the hole at the top. The pump does not start dry, to prolong the life of the pump, it is better not to regret the money and to put a special device on dry running.
- To the pump are connected metal-plastic pipes with an internal diameter no less than the diameter of the pump branch pipe.
Caution: Do not use flexible rubber hoses as conduits, the discharge may cause their compression.
- is carried out after filling with water, providing electricity and establishing a pipeline, then pressure adjustment is performed in accordance with the standard values set by the manufacturers and the pump is ready for operation.
Connecting the pumps to the well
If a pump with a capacity of 60 liters per minute is sufficient for a family of 4 people, gardeners-gardeners should select more powerful structures. The correct operation of the system depends on the knowledge of how to do the work and what to do before starting work.
So:
- When deciding how to connect the pump to the well, you should determine and select the right model for your site. The market is represented by fine models of Chinese production, but not artisanal, namely industrial, so it is taken for an example.
The standard design diameter is 75 mm and an inch internal thread is provided for the output. - In addition to the pump itself, additional components are needed. The pump will be in a suspended state at a depth, therefore insurance is necessary.
The most reliable insurance is carried out by a rope in 3 mm, such thickness will be enough. - A loop is made on two clamps. Why there are two reasons for this. A cable is passed through the loop, which is also clamped.
From vibration, one nut clamp can unscrew the nut and the loop will simply fall apart, then the pump remains without insurance at all. Insurance will always allow you to pull the pump out. - With pump included electrical cable. Its length is sufficient to raise the connection above the water, this program is at a minimum, and out of the well, as a maximum.
- The kit contains a cable sealing connection. It consists of a pair of rolls of insulating tape, sealant and a device that professional electricians call the hermetic.
A set of accessories on this ends, then the interest is represented by a pipe. - Pipe for the pump is selected from low-density polyethylene (HDPE) and it is recognized as the ideal product for these pumps.
- The pipe is connected to the pump using a fitting. The clutch has an inch size outside on 32, or 32 per inch outer.
Since the dimensions are commensurable, the clutch is screwed onto the pump, and then there is no problem for inserting the pipe. - How to connect a surface pump to a well, here the scheme of action is extremely simple and is tied to the installation of a non-return valve. The pumps have a non-return valve, its function is to keep water at a certain level when the pump is shut off and it is built into the structure.
It can be noted that the pump is at rest for longer than running. It turns on for pumping water and forcing it into the pressure system.
If you try to move the check valve from place with your finger, you can notice that this plastic thing is hanging inside and has proven itself to be an unreliable element in operation. Therefore, it is always duplicated by a separate product made of brass.
Italian manufacturers have mastered the production of check valves made of brass, which has a brass baffle and rubber seal. It is indicated by the arrow. - Connecting two products with an internal thread requires one more connecting element with male thread - nipple.
- It is screwed into the pump, a non-return valve is wound on it, and then there is a fitting for connecting the pipe.
- It can be stated that the pump is mounted, the tube is stuck, the cable is brought to the surface and these three component elements protrude from the well.
Attention: To give a civilized design, a wellhead is used which, when closely examined, contains all the elements for camouflaging and securing the cable and cable, has an opening with a sealing nut for the pipe, which prevents the entry of water or air into the well.
- The assembled structure is lowered into the well and at this stage it is possible to check the operation of the pump. The process of waiting for the appearance of water is on and on. The water does not go.
- Specialists dealing with the problem of pumps, with an accuracy of 99.0% guarantee that if they had not installed an additional check valve, the water would have gone right away, but here the effect of an "inverted glass" was obtained. Therefore, it is necessary to take a pipe and draw in air from it, so that the impellers are filled with water and forced out the remains of air.
Some advise to remove the check valve to a height of one meter from the pump, but does it make sense to solve the owners. - Connection of the surface pump to the well with automatic work is ensured by the installation of a minimum and maximum level in the storage tank.
- Most often float-type products are purchased, allowing them to place their contacts in the coil of the starter.
Everyone wants to have reliable equipment in their work and not to deal with problems of repair and reconstruction for many years. Pump stations deserve such attention.
