Water level control in the Rozhnovsky tower. Installation and connection of a pumping station Prices for a pumping station

Individual water supply of a private house or cottage can be from two sources - or a well. To automate the supply of water to the house, as well as to create a stable pressure, it is necessary to install a pumping station. It consists of a pump, and a safety group (pressure gauge and drain valve). The advantage of this idea is that any household appliances can work with such a water supply scheme, another good news is that connecting is not a very difficult task, if you wish, you can install and connect a pumping station with your own hands.

Selecting an installation site

Pumping stations are installed near a water source - a well or a well - in a specially equipped pit - a caisson. The second option is in the utility room in the house. The third is on a shelf in the well (such a number will not work with a well), and the fourth is in the underground.

Installation of a pumping station in the subfield - the noise from its operation may be too loud

How to determine the depth of suction

When choosing a place, they are primarily guided by technical characteristics - the maximum suction depth of the pump (from where the pump can lift water). The thing is that the maximum lifting depth of pumping stations is 8-9 meters.

Suction depth - the distance from the water surface to the pump. The supply pipeline can be lowered to any depth, it will pump water from the level of the water mirror.

Wells often have a greater depth than 8-9 meters. In this case, you will have to use other equipment - a submersible pump or a pumping station with an ejector. In this case, water can be supplied from 20-30 meters, which is usually enough. The disadvantage of this solution is expensive equipment.

Suction depth - a characteristic that determines the installation method

If you are only a meter away from being able to install conventional equipment, you can put the station in a well or above a well. A shelf is attached to the wall in the well, in the case of a well, a pit is deepened.

When calculating, do not forget that the level of the water mirror "floats" - in the summer it usually goes down. If your suction depth is on the verge, there may simply be no water during this period. Later, when the level rises, the water supply will resume.

Security Considerations

Another point to consider is the safety of the equipment. If the installation of a pumping station is supposed to be near a house with permanent residence, there are fewer problems - you can choose any option, even in a small shed. Only one condition - it should not freeze through in winter.

If this is a dacha where they do not live permanently, the matter is more complicated - it is necessary to arrange a room that is not striking. The safest way to install a pumping station is in the house. Although they can carry it away in this case.

The second place where you can install a pumping station is a buried camouflaged caisson.

The third is on a shelf in the well. Only in this case, the traditional one is not worth doing. You need a steel lid, which is locked with a reliable lock (weld loops to the ring, make slots in the lid, on which to hang locks). Although, a good cover can also be hidden under the house. Only the design must be thought out so that it does not interfere.

Convenience and operating conditions

Installing a pumping station in the house is good for everyone, except that the equipment makes noise during operation. If there is a separate room with good sound insulation and it is possible according to the technical characteristics, there is no problem. Often they make a similar room in the basement or in the basement. If there is no basement, you can make a box in the underground. Access to it is through a hatch. This box, in addition to sound insulation, must also have good thermal insulation - the operating temperature range starts from + 5 ° C.

To reduce the noise level, the station can be placed on thick rubber to dampen vibration (created by a cooling fan). In this case, even installation in the house is possible, but the sound will certainly still be there.

If you stopped at the installation of a pumping station in a caisson, it must also be insulated and also waterproof. Usually, ready-made reinforced concrete containers are used for these purposes, but a caisson can be made of concrete rings (like a well). Install the ring with the bottom down, the ring with the lid on top. Another option is to lay it out of brick, pour concrete on the floor. But this method is suitable for dry areas - the groundwater level should be lower by a meter below the depth of the caisson.

The depth of the caisson is such that the equipment is installed below the freezing level. Expanded polystyrene insulation. Better extruded. Then you also get waterproofing at the same time.

For a caisson of concrete rings, it is convenient to use a shell (if you find a suitable diameter). But you can also slab polystyrene foam, cut into strips and glue it. For rectangular pits and structures, slabs are suitable that can be glued to walls using bituminous mastic. Lubricate the wall, apply insulation, you can additionally fix it with a pair of nails / dowels.

Connection of a pumping station

Choosing equipment and a place for installation is half the battle. You also need to correctly connect everything into a system - a water source, a station and consumers. The exact connection diagram of the pumping station depends on the chosen location. But anyway there is:

Suction pipeline that descends into a well or well. He goes to the pumping station.
The station itself.
The pipeline going to consumers.

All this is true, only the strapping schemes will change depending on the circumstances. Let's consider the most common cases.

Water supply from a well for permanent residence

If the station is placed in a house or in a caisson somewhere on the way to the house, the connection scheme is the same. A filter (most often a regular mesh) is installed on the supply pipeline lowered into a well or well, a check valve is placed after it, then a pipe already goes. Why the filter - it is clear - to protect against mechanical impurities. A check valve is needed so that when the pump is turned off, water under its own weight does not flow back. Then the pump will turn on less often (it will last longer).

The pipe is brought out through the wall of the well at a depth just below the freezing level of the soil. Then it goes into the trench at the same depth. When laying a trench, it must be made straight - the fewer turns, the lower the pressure drop, which means that water can be pumped from a greater depth.

To be sure, you can insulate the pipeline (lay sheets of polystyrene foam on top, and then fill it with sand, and then with soil).

Passage option not through the foundation - heating and serious insulation are required

At the entrance to the house, the supply pipe passes through the foundation (the place of passage should also be insulated), in the house it can already rise to the installation site of the pumping station.

This method of installing a pumping station is good because if everything is done correctly, the system works without problems. The inconvenience is that it is necessary to dig trenches, as well as bring the pipeline out / in through the walls, and also in the fact that it is difficult to localize damage when a leak occurs. To minimize the chances of a leak, take proven quality pipes, lay a whole piece without joints. If there is a connection, it is desirable to make a manhole.

There is also a way to reduce the volume of earthworks: lay the pipeline higher, but it is good to insulate it and use it additionally. This may be the only way out if the site has a high level of groundwater.

There is another important point - the well cover must be insulated, as well as the rings on the outside to the freezing depth. It's just that the section of the pipeline from the water mirror to the outlet to the wall should not freeze. For this, insulation measures are required.

Connecting the pumping station to the water supply

Often a pumping station is installed with a centralized water supply. In this case, a water pipe is connected to the inlet of the station (also through a filter and a check valve), and the outlet goes to consumers.

It is advisable to put a shut-off valve (ball) at the inlet so that if necessary you can turn off your system (for repairs, for example). The second shut-off valve - in front of the pumping station - is needed to repair the pipeline or the equipment itself. Then it also makes sense to put a ball valve at the outlet - in order to cut off consumers if necessary and not drain water from the pipes.

Well connection

If the suction depth of the pumping station for the well is sufficient, the connection is no different. Unless the pipeline exits at the point where the casing pipe ends. A caisson pit is usually arranged here, and a pumping station can be installed right there.

Pumping station installation: well connection diagram

As in all previous schemes, a filter and a check valve are installed at the end of the pipe. At the entrance, you can put a filler tap through a tee. You will need it for the first start.

The main difference between this installation method is that the pipeline to the house actually runs along the surface or is buried to a shallow depth (not everyone has a pit below the freezing depth). If the pumping station is installed in the country, it's okay, the equipment is usually removed for the winter. But if the water supply is planned to be used in winter, it must be heated (with a heating cable) and insulated. Otherwise it won't work.

Starting the pumping station

In order to put the pumping station into operation, it is necessary to completely fill it and the supply pipeline with water. For this purpose, there is a special filler hole in the body. Pour water into it until it appears. We twist the plug into place, open the tap at the outlet to consumers and start the station. At first, water goes with air - air plugs come out, which formed during the filling of the pumping station. When the water flows in an even stream without air, your system has entered the operating mode, you can operate it.

If you filled in water, and the station still does not start - the water does not pump or comes in jerks - you need to figure it out. There are several possible reasons:

there is no non-return valve on the suction pipeline lowered into the source, or it does not work;
somewhere on the pipe there is a leaky connection through which air is leaking;
the resistance of the pipeline is too high - you need a pipe of a larger diameter or with smoother walls (in the case of a metal pipe);
water mirror is too low, not enough power.

To prevent damage to the equipment itself, you can start it by lowering the short supply pipeline into some kind of container (tank of water). If everything works, check the line, suction depth and check valve.

Staying outside the city, in a country residence, has additional difficulties, since not everywhere there are centralized communications. Residents of the periphery improve the living conditions in a cottage or house so that it does not differ from comfortable urban housing. One of the points of a comfortable life concerns the constant availability of water in sufficient quantities. In this case, special equipment will help - a do-it-yourself pumping station. Due to self-installation, you can save the family budget.

The main number of wells in summer cottages has a depth of up to 20 m - optimal for the installation of automatic equipment. With these parameters, it is not necessary to purchase a deep pump, an automatic control system or an intermediate tank: water flows directly from the well (or well) to the points of analysis. To ensure the correct connection of the pumping station, you need to figure out what it consists of and how it works.

The main functional units of the station are the following equipment:

, providing the rise of water and its transportation to the house.
Hydraulic accumulator softening water hammer. It consists of two parts separated by a membrane.
Electric motor connected to pressure switch and pump.
Pressure switch that controls its level in the system. If the pressure drops below a certain parameter, it starts the motor, if there is an excess of pressure, it turns it off.
A manometer is a device for measuring pressure. It is used to make adjustments.
A water intake system equipped with a check valve (located in a well or well).
The main line connecting the water intake and the pump.

Using this formula, you can determine the maximum suction depth: the diagram clearly shows what measurements need to be made for this

The most common version of the pumping station is a hydraulic accumulator with a surface pump fixed on top and an assembly including a pressure gauge, pressure switch and dry running protection

As can be seen from the table, the cost of pumping stations can be different. It depends on the power, maximum head, throughput, manufacturer

Before installing pumping equipment, it is necessary to purchase all functional parts according to the parameters of the well and the water supply system.

Self-assembly of a pumping station

At first glance, there are quite a few places for mounting equipment - this is any free corner in the house or outside it. In fact, everything turns out differently. However, only a well-thought-out installation of a pumping station guarantees its full operation, so some conditions must be observed.

Installation conditions:

proximity to a well or well ensures stable water absorption;
the room should be warm, dry and ventilated;
the location should not be cramped, as preventive and repair work will be required;
the room should hide the noise that pumping equipment makes.

One of the options for installing a pumping station is on a shelf specially attached to the wall. The installation room is a boiler room, boiler room or utility room

It is difficult to meet all the conditions, but it is desirable to adhere to at least some. So, let's look at a few suitable places for installation.

Option # 1 - a room inside the house

A well-insulated boiler room on the territory of the cottage is an ideal area for installation in case of permanent residence. The main disadvantage is good audibility with poor sound insulation of the room.

If the pumping station is located in a separate room of a country house, then it is best to arrange a well directly under the building

Material on how to make a borehole water supply system will also be useful:

Option #2 - basement

An underground or basement can be equipped for the installation of a pumping station, but this should be considered when designing. If there is no heating in the room, and the floors and walls are not insulated, you will have to spend a lot of effort to prepare it.

A well-equipped basement is great for installing a pumping station. During the laying of the pipeline in the foundation of the house, a hole should be made for communications

Option # 3 - a special well

A possible option that has a couple of pitfalls. The first is the difficulty in maintaining the desired level of pressure in the house, the second is the difficulty in performing repairs.

When the pumping station is located in a well, on a specially equipped site, the pressure level should be adjusted, which depends on the power of the equipment and the parameters of the pressure pipe

Option # 4 - caisson

A special platform near the exit of the well is also suitable for installation, the main thing is to correctly calculate the depth of its location. The required temperature will be created by the heat of the earth.

The pumping station, located in the caisson of the well, has two advantages: complete noise insulation and protection against freezing during frost

In the absence of specially designed places, the unit is installed in common areas (in the hallway, bathroom, corridor, kitchen), but this is an extreme option. The loud noise of the station and comfortable rest are incompatible concepts, therefore it is better to prepare a separate room for the installation of a pumping station in the country.

Pipeline laying

The well is usually located near the house. In order for the pumping station to work properly and without interruption, it is necessary to ensure an unhindered flow of water from the source to the equipment, which is located in a specially designated place. For this purpose, a pipeline is being laid.

Low winter temperatures can cause pipes to freeze, so they are buried in the ground, preferably to a depth that is below the freezing level of the soil. Otherwise, the line should be insulated. The work is as follows:

digging a trench with a slight slope towards the well;
device in the foundation of a hole for the pipe at the optimum height (if necessary);
pipe laying;
connection of the pipeline to the pumping equipment.

During the construction of the highway, one may encounter such a problem as the presence of high-standing surface waters. Pipes in this case are mounted above the critical level, and heat-insulating material or a heating cable is used to protect against cold.

The advantages of polyethylene pipes and fittings over metal counterparts: no corrosion, ease of installation and repair, low price (30-40 rubles / m)

This diagram of the installation of a pumping station shows the option of insulating pipes above the level of soil freezing

The best option for thermal insulation of external water pipes is a solid "shell" of expanded polystyrene (thickness - 8 cm), wrapped in foil

For thermal insulation of pipes that are laid above the freezing level of the soil, an inexpensive and environmentally friendly material is often used - basalt-based mineral wool.

outdoor work

On the outside of the polypropylene pipe, we fix a metal mesh, which will serve as a coarse filter. In addition, you will need a check valve to ensure stable filling of the pipe with water.

It is possible to purchase a ready-made hose with a check valve and a coarse filter, but a self-equipped one will cost much less.

Without this part, the pipe will remain empty, therefore, the pump will not be able to pump water. The non-return valve is fixed using a coupling with an external thread. The end of the pipe equipped in this way is placed in the well.

The coarse filter for the supply hose is a metal mesh with a fine mesh. Without it, the correct operation of the pumping station is impossible.

After completing these steps, you can start refining the head of the well.

Connecting equipment

So, how should you properly connect a home pumping station so that you do not encounter technical inconsistencies in the future? First of all, we install the unit on a specially prepared base. It can be brick, concrete or wood. To ensure stability, we screw the legs of the station with anchor bolts.

For the installation of the pumping station, special legs-stands are provided, however, to give additional stability, the equipment must be fixed with bolts

Placing a rubber mat under the equipment can dampen unwanted vibrations.

For more convenient maintenance, the pumping station is installed on a base as high as an ordinary table, made of durable material - concrete, brick

The next step is to connect the pipe coming from the well. Most often this is a polyethylene product with a diameter of 32 mm. For connection, you will need a coupling with an external thread (1 inch), a metal corner with an external thread (1 inch), a check valve with the same diameter, an American straight tap. We connect all the details: we fix the pipe with a coupling, we fix the “American” with a thread.

One of the check valves is located in the well, the second is mounted directly to the pumping station. Both valves serve to protect the system from water hammer and ensure the correct direction of water flow.

The second output is intended for communication with the water supply network. It is usually located at the top of the equipment. Connection pipes are also made of polyethylene, as it is an inexpensive, plastic, durable material. Fixing occurs in a similar way - using an "American" and a combined coupling (1 inch, 90 ° angle) with an external thread. First, we fasten the “American” to the outlet of the station, then we mount a propylene coupling into the tap, and finally we fix the water pipe in the coupling by soldering.

For complete sealing of joints, their sealing is necessary. Traditionally, linen winding is used, a special sealing paste is applied on top of it.

After you have connected the pumping station to the water intake and water supply system, you need to check the quality of its work.

Carrying out a trial run

Before starting the station, it must be filled with water. We let water through the filler hole so that it fills the accumulator, lines and pump. Open the valves and turn on the power. The engine starts and water begins to fill the pressure pipe until all air is removed. The pressure will increase until the set value is reached - 1.5-3 atm, then the equipment automatically turns off.

In some cases, it is necessary to adjust the pressure value. To do this, remove the cover from the relay and tighten the nut

As you can see, it’s not difficult to install a home pumping station with your own hands, the main thing is to follow the installation instructions.

A pumping station is an excellent piece of equipment that allows you to automate the process of drawing water from a well. A complex of technical devices activates the system launch when it is necessary to replenish stocks and turns off the units at the right time. Incredibly increase the degree of comfort. After all, it is also necessary to enjoy the achievements of civilization outside the city, do you agree?

However, incredibly useful equipment is not enough just to buy, you need to know how to install and connect. We invite you to read the article, covering all the issues in great detail. This information will be useful to all owners of suburban housing, no matter whether the pumping station is connected by hand or hired workers are invited to install it.

In our article, you will get acquainted with the varieties of pumps used in groundwater intake systems. Also here are all possible options for the location of equipment and connection to an autonomous water supply. The information is supported by diagrams, photo materials and video.

The pumping equipment station performs two functions at once - it supplies water to the house's water supply system and automatically maintains the set pressure in it.

This allows you to lay an extensive network of water pipes and connect household appliances to it - a shower cabin, a boiler, a dishwasher and a washing machine.

Typical station design includes:

Pump;
Hydraulic accumulator;
Block of automation;
Inlet strainer - necessary to prevent particles of impurities and possible contaminants from entering the system;
Piping, hoses and necessary fittings.

To prevent the outflow of liquid from the system when the pump stops or the pressure drops, a check valve is installed in the water intake area. You also need a source of water intake. To do this, arrange a well or well.

It is possible to use a reservoir (pool) with imported water and open reservoirs, if the characteristics of the unit allow pumping contaminated liquid.

Types of pumps used

In the water supply system of the house, it performs the following functions:

Protects the pump from wear and increases its service life - due to the supply of liquid in the membrane compartment, the number of unit starts is significantly reduced.
Maintains constant water pressure and protects against pressure surges.
Eliminates the occurrence of water hammer in the system, destructively acting on the connected devices and pipeline fittings.
Provides some water supply in the event of a power outage.

The device is a sealed vessel, the internal volume of which is divided by an elastic membrane into two containers. One of them is filled with air, and the second is designed for pumping water.

The hydraulic tank works as follows. Water is pumped into the elastic container until the upper pressure threshold is reached. The pump then turns off.

The pressure in the system is maintained by the air gap in the accumulator, the compressed air plays the role of a damper. When the volume of water decreases (consumed by consumers), and the pressure reaches the lower specified limit, the pump turns on again and fills the hydraulic tank with water.

A hydraulic accumulator is selected based on calculations that take into account the number of residents, the number of water consumption points, the maximum allowable number of pump starts and its power, and the required pressure in the system.

Insufficient working volume of the tank will cause the pump to constantly turn on and wear out. A container with a margin threatens to stagnate water and reduce its quality, a harmful effect on the inner surface of the membrane.

In other cases, the elements of the system are mounted independently. When installing a surface station, a pipeline (or two pipelines if a remote ejector is used) from the well is connected to the pump.

Next, install the accumulator and control unit. For a station with a borehole pump, these will be all the main surface elements in the scheme. It is most convenient to use a 5-pin fitting for this, which is mounted in a pressure pipeline in a convenient place. A pressure switch and a pressure gauge are screwed into it.

A hydraulic accumulator is connected to the side inlet of the fitting. For ease of maintenance, it is connected through a ball valve with an American and a drain is arranged.

Conduct the connection of consumers to the pumping station. Most often, the distributing collector of cold water becomes the first element.

Step # 5 - the first launch of the station

The pump electric motor has a large power, so it is better to provide the pumping equipment station with its own power line, arrange grounding and install a voltage stabilizer.

Check the pressure of the accumulator air chamber. It must be 10% less than the start pressure of the pump. However, this setting is done in the operating mode. First, it is necessary to achieve the following values: for a hydraulic tank with a capacity of 20-30 liters - 1.4 ... 1.7 bar, with a capacity of 50-100 liters - 1.7 ... 1.9 bar.

Before the first start of the installation with a surface pump, the working part of the system is filled with water. To do this, unscrew the plug from the filler hole located at the top of the pump.

If a funnel is provided in the pipeline, it is better to use it. Pour in the liquid until it is completely filled, until it starts to pour out. Then the hole (valve) is tightly closed.

Start sequence:

The pump is connected to the mains.
The valve of the filler funnel of the pipeline with a surface pump is slightly opened to remove the remaining air that has entered the system.
Turn on the unit - within 2-3 minutes, water should flow from the outlet of the pressure pipeline (or an open tap).
If the liquid has not flowed, the pumping equipment is turned off, water is added to the system and turned on again.

After a successful launch, the equipment should be “run in” and, if necessary, adjust the settings of the valve body and pressure switch.

Basic rules of operation

After the pumping station is put into operation, its periodic maintenance is carried out. It is necessary to clean the coarse filter in a timely manner. Without this, the performance of the installation will gradually decrease, the water will flow in jerks, and a completely clogged filter will lead to a “dry” operation and shutdown of the system.

The frequency of cleaning depends on the content of impurities in the pumped water.

You can read information about common breakdowns of the pumping station and how to fix them in the following article.

How to make a pumping station based on a submersible pump:

Proper installation of the pumping station provides a private house with water supply with parameters that are not inferior to a city apartment - constant pressure and sufficient pressure.

In order for the system to work as efficiently as possible, before choosing and installing equipment, you should seek the advice of a specialist and perform an estimated calculation.

If you have experience in self-assembly and installation of a pumping station, please share your knowledge in the comments to this article. If you have any questions after reading the material, feel free to ask them in the comments below.

Most often you can find water towers of the Rozhnovsky system, made according to a standard design. Rozhnovsky towers with a capacity of 15, 25, 50 m 3 provide water supply for small settlements, factories and factories, railway stations, livestock and poultry complexes, MTS, etc.

The successful design of Rozhnovsky of the 30s of the last century, which still serves faithfully to this day, includes an overflow pipe as an element of minimal automation that prevents the tower from overflowing. With visual control of the overflow, it is still impossible to avoid the loss of artesian water and, accordingly, the energy spent on its rise.

Modern automation tools allow you to control the water level in the tower and make timely switching on and off of pumps, ensuring their safe operation, energy saving, etc. But, often, however paradoxical it may be, the user, who has equipped the water tower with modern automation equipment, continues to rely on the overflow pipe as the ultimate remedy for overflow. Obviously, the problem lies in the failure of automated systems, mainly level control devices. The consequences of the inaction of the level control system, including the overflow pipe itself, can sometimes be seen in winter in the form of a huge ice hanging from the water tower.

With a fairly wide market offer of level control devices, the question arises of choosing the right level sensor.

Offered:

Float sensors (sliding on the rod, inclined, floating suspended);
Capacitive sensors cut into the tank wall;
Capacitive sensors embedded in the tank cover,
Non-contact ultrasonic sensors;
Conductive sensors;
Hydrostatic level sensors;
Hydrostatic pressure sensors.

Perhaps, one can immediately reject the sensors installed by inserting into the wall of the tank due to the ice that forms on the inner walls of the support and the tank in winter, the thickness of which can reach 30 cm and serve as a natural heat insulator in the unheated Rozhnovsky tower. These are capacitive sensors, the second on the list.

Following are the fifth conductive sensors in the list. When the temperature drops, the conductivity of water decreases greatly, and when a slight icing appears on the metal probe of the conductive sensor, its sensitivity is reduced to zero, because. ice is a dielectric.

Particular attention should be paid to sensors that are installed from above: on the roof or under the roof of the tower. To install them, it is necessary to lay the cable up, taking measures to prevent breakage due to icing, gusts of wind, mechanical and other influences. If all conditions are met, the fourth non-contact ultrasonic liquid level transmitters in the list can normally function, but only those that guarantee stability at temperatures below 0C. Ultrasonic sensors, among others mentioned here, are characterized by high cost.

Capacitive sensors cut into the roof of the tank. To control the upper and lower levels, two sensors will be required, following the rules for laying the cable up. The sensors have long probes; to control the lower level, a probe corresponding to the height of the tank will be required. The cost of this solution is quite high, approaching or even exceeding the cost of the ultrasonic method.

Of the float sensors, the pop-up type is operable, but it also freezes over, especially the upper level sensor when the float is free at low water.

Level gauges of this type are also used for continuous measurement of medium pressure. The main tasks solved with the help of these level gauges are: Evaluation of the level of liquids in large stationary storage tanks.

The current control relay is designed to convert the input signal 4 ... 20mA into the output signal of the relay.
The device is an intelligent relay for level control and pump control tasks. Using the "Teach-In" function, it is possible to "remember" two level values in the current range 4 ... 20mA, as well as assign one of the programmed modes to control the output relay contact. To turn the pump on and off for filling according to two-level logic, the Switching Difference mode is provided.

One of the first engineering systems that are created in private households is plumbing. Its use is necessary even at the construction stage. Without a plumbing system, a full-fledged round-the-clock living in a house is impossible. Modern houses have as part of their engineering networks not only ordinary taps, but also automatic devices that use water. In order for your house to have water pressure around the clock, each owner needs to know how to connect a pumping station.

What is a pump station?

When building an autonomous water supply system and connecting the water supply of a private house to the main utility networks, each owner wants to receive a constant pressure of water in the system. So, to lift water from a well or from a well located on a personal plot, pumping devices can be used. They come in various models and capacities, can be located in various segments of the plumbing system. Submersible pumps are lowered directly into a well or into a well, while surface pumps are placed at ground level, taking water with an inlet hose.

The pump should not run continuously. Continuous operation leads to rapid wear of the components and mechanisms of this device. At the same time, do you want to use water at any time of the day? There is a way out: to ensure a constant pressure in the pipelines of the water supply system, a station of pumping equipment is assembled.

The main parts of the pumping station

H asos. Usually, surface pumps are used in a set of stations, which take water from a well, well or main network through an inlet pipe with a filter.
Pressure accumulator or hydraulic accumulator. It is usually a container of a certain size, inside which there is an elastic rubber partition or inner container. When the system pressure increases, the container or partition expands, and when the pressure decreases, it contracts, squeezing water into the system and maintaining constant pressure parameters.
Control node, which determines when the pumping device turns on and when it stops working. The on and off parameters are determined by the pressure in the system, which is measured by a pressure gauge.

Options for installing a pumping station

Stations of pumping equipment, regardless of the location of the water source, can be installed in three main places.

Features of choosing the location of the pumping station

Options for connecting a pumping station

Depending on the configuration of the water supply system, you can choose one-pipe and two-pipe schemes for connecting the pumping equipment station. A two-pipe system is used to increase the depth from which the pumping equipment station can lift water.

A single-pipe scheme is used with a well depth not exceeding 10 meters. If it exceeds 20 meters, then it is preferable to use a two-pipe scheme with an ejector.

Connection of a pumping station (two-pipe scheme)

At the initial stage, an ejector is assembled, which is a separate unit made of cast iron, with three outlets for connecting the pipeline.

First, we mount a filter mesh on the ejector (in its lower part), which protects the pumping equipment from failure when small stones or sand enter from a well or well.
A plastic socket is mounted at the top of the ejector assembly, to which a 3.2 cm spigot is attached. You may have to mount several slings at the same time in order to reach the section of the water pipe.
At the end of the drive, we mount a coupling that will ensure the transition to a plastic pipeline. Usually such a coupling is made of bronze.

When connecting the elements, pay special attention to the tightness of the connections. Of course, a leak in a well or well will not cause you aesthetic inconvenience, however, air intake in leaky joints can lead to instability in the system and a significant decrease in its power. Threaded connections are sealed with a special paste, fum-tape, linen wrapping or rubber gaskets.

Remember! Water supply pipelines must either run below the freezing depth of the soil, or be suitably insulated.

When introducing water supply pipes into a caisson or to another installation site of a pumping equipment station, it is necessary to provide them with some margin in length. After the pipes are removed, we begin to connect the pumping equipment station to the pipelines from the well.

We install a cap on the casing pipe of the drilled well.
We find out the depth of lowering the pipes into the water well. To do this, we lower any solid long object into the drilled shaft. The level of placement of the inlet pipe of the pumping equipment station should be about a meter from the bottom of the well so as not to suck in sand, silt or stones from the bottom.
We attach polyethylene pipes to the ejector assembly. The length of the pipe should be equal to the sum of the distance from the wellhead to the pump and the depth of the well (minus one meter).
At the head of the well, we mount a knee with a turn of 90 degrees.
We push plastic pipes through the straight elbow leading to the ejector assembly (after installation is completed, the space between the inside of the elbow and the pipelines can be filled with mounting foam). In a straight elbow, the pipes can be both bent and connected by adapters with a rotation angle of 90 degrees.
We lower the ejector device to the required depth. You can verify the correct installation depth of the ejector by the mark that we previously made on the pipeline.
We fix a homemade head on the top of the casing pipe, which we have consists of a pipe elbow turned at an angle of 90 degrees. You can fix the "head" on the casing pipe of the well with a specialized adhesive tape for plumbing with reinforcement.

We bring water pipes to the house. You may need to provide turns. The entrance of water pipes through the foundation must be located below the freezing line of the soil. The removed pipes are connected to the water pipe of the pump as part of the station. The connection of pipelines is made using a wrench or adjustable wrench.

There is usually a filling port on the top of the pump in the equipment station. It is necessary so that it does not run dry. Filling with water is carried out only at the initial start-up or when starting after a long period of inactivity.

Before starting the pumping station, check the operating pressure in the accumulator. Usually it is 1.2 - 1.5 atmospheres. You can increase the operating pressure with a conventional automobile pump. For pumping on pressure accumulators in water supply systems, there is a special nipple.

How to connect the pumping equipment station to the main water supply

Sometimes it is required to connect the pumping equipment station not to a well or well, but to the main water supply. This is true when connecting to utility networks with low or unstable pressure. You can make such a connection in the following sequence.

We regulate the operation of the pumping equipment station

After installing the connecting elements, the system must be run in test mode to check the tightness and performance of all its segments. Before starting, water is poured into the filling hole of the station of the pumping equipment, this excludes the operation of the device "dry".

As a rule, all adjustment parameters are set at the station even before it is launched, based on the calculated parameters of the house's plumbing system. During operation, the working units of the station of pumping equipment may wear out, therefore, approximately once a year, it is desirable to carry out additional adjustment of the pump operation parameter. Precise adjustment of the pumping equipment system with built-in pressure accumulators is carried out by its own automation unit.

An important nuance. All stations of pumping equipment incorporate an electric motor. It can have a lot of power, so we recommend that you provide such a station with your own power line. The power line of the station will operate in a humid environment, so take care to install protected sockets and lay cables in special corrugated tubes.

As you can see, connecting a pumping equipment station is available even to a non-professional with minimal technological skills. Its installation will help you ensure uninterrupted water supply to your home and garden.
