Hammer pumping station connection plan. How to properly install, run and configure a pumping station. What automation is suitable for a vibration pump

Before installing the plumbing system, you need to draw up a detailed wiring diagram, focusing on how the water supply will be carried out - centrally or autonomously, and what is the number of water intake points - dishwasher and washing machine, hot water supply, kitchen faucet, sink, shower, toilet, bath. In addition, it is necessary to calculate the approximate consumption of water consumed, taking into account the number of people living in the house, as well as watering the garden and garden. And find out what should be the scheme for connecting it to the water supply network. You can learn about all this in this article.

What is a pumping station?

When constructing an autonomous water supply system and connecting the water supply to public utility networks, the consumer dreams of a regular water pressure in the system. Thus, special pumping equipment can be used to lift from a well located on a personal plot or a well. It comes in various capacities and models, it can be located in various parts of the plumbing system. Surface devices are placed at ground level, submersible devices are lowered directly into a well or well.

Main elements

Pumping equipment should not work constantly, as continuous operation can lead to rapid wear of the mechanisms and components of this device. However, you want to use water at any time of the day. There is a way out - a pumping station is being assembled (the connection diagram and main parts are presented below), which provides a constant pressure in the water supply system. So, consider the main components of the pumping station.

Pump

Very often equipped with surface pumps. They, through an inlet pipe with a filter, pump out water from the main network, well or well.

Battery

A hydraulic accumulator (or pressure accumulator) is a structure of certain overall dimensions, inside of which there is an internal container or an elastic rubber partition. With an increase in pressure in the system, the partition or container expands, respectively, when it decreases, it contracts, directing water into the system and maintaining constant pressure indicators.

Control node

This element determines at what point the pumping device should be started, and when its operation is not required. The switching on and off parameters are determined by the pressure parameters in the system, measured by means of a manometer.

Installation options

Regardless of the location of the water source, the installation of a pumping station can be carried out in three main places - in the basement, a separate building and a caisson. Let's consider them in more detail.

Basement

Such an installation of a pumping station greatly facilitates the maintenance of equipment, since in this case free access to the mechanisms for their repair and maintenance is provided. However, pumping devices are a rather noisy thing, so when choosing this option, you should think about soundproofing measures.

Detached building

In this case, the scheme for connecting the pumping station to the well is provided in a separate building, which is located above the mouth of the well or well. Despite the obvious benefit of this option, the construction of a separate structure for technical structures is a rather costly process.

Caisson

A caisson is a structure that outwardly resembles a container, whose bottom is arranged below the freezing level. It is possible to build large-sized caissons in which it is allowed to place pumping equipment.

Pumping station: reviews

According to consumer reviews of pumping equipment used in stations, in most cases it is not satisfactory. If you want to make sure, it is advisable to purchase stations with equipment from well-known European companies.

Choice of accommodation

Before choosing where the pumping station will be located (the connection diagram also depends on the location), you need to know the requirements for its installation.

To avoid increased vibration, the pumping station must be installed on a solid foundation. The lack of reliable fastening and a solid foundation can lead to the fact that backlash will form at the junctions of the pipelines, which will provoke leaks. But at the same time, pumping equipment should not come into contact with the ceiling and walls.
The pumping station (the connection diagram is presented below) must be installed either in a heated room, or must be qualitatively isolated from the effects of negative temperatures. Otherwise, a decrease in temperature can lead to damage to almost all components.

If you plan to use the station year-round, then you will need to make quite complex preparatory work. Automatic pumping stations (connection diagrams also need to be thought out in advance) must be installed in warm rooms, and the pipeline from the house to the well must be laid below the freezing level or insulated.

Organization of the plumbing system

In this case, the ideal option is an autonomous water supply system, which is easy to build. And the cost of such a system is quite democratic. Therefore, it remains to find out what the pumping station for a private house should be, the scheme for connecting it to the water supply system.

There are two main schemes for organizing an autonomous water supply system: based on a well and based on a well. The device of an autonomous network in the latter case begins with drilling a well. It is desirable if the project for the well, the wiring of communications and the installation of the pumping station will be carried out in conjunction with the design of the main building and courtyard buildings. In this case, it is possible to design the installation of a part of the equipment on the basement floors, buildings adjacent to the building or in the basement in such a way that the well and the pumping station (expert reviews confirm this) are in harmony with the general architectural style of the estate. And most importantly, this option in the winter does not require additional protection of communications and equipment from freezing. Equipment arranged in one place will be convenient for repair and maintenance.

Pumping stations for the home: connection diagram

Depending on the configuration of the plumbing system, you can choose to connect the station to a one-pipe or two-pipe system. The latter option is used to increase the depth from which pumping stations for the house (the connection diagram is discussed below) can receive water.

If the depth of the well is not more than 10 meters, then in this case a single-pipe scheme is used. With a suction depth of more than 20 meters, it is more expedient to use a two-pipe scheme with an ejector.

Two-pipe scheme

Connecting a pumping station to a well: a two-pipe scheme.

At the first stage, it is necessary to assemble the ejector, which is a separate cast iron assembly with three outlets for connecting the pipeline.
A filter mesh is installed at the bottom of the ejector, which, when sand or other small particles enter from a well or well, protects pumping equipment from failure.
Then, a plastic socket is installed in the upper part of the ejector, a 32 mm cross section is connected to it. To reach the cross section of a water pipe, you may have to mount several spurs at the same time.
At the end of the downstream, a coupling is installed that provides a transition to a polyethylene pipeline. As a rule, this coupling is made of bronze.
Next, a cap is installed on the well casing.
After that, the required depth of the pipeline is determined. To do this, a long object is lowered into. As a result, the level of the inlet pipe should be about one meter from the bottom of the well to prevent stones or sand from entering from the bottom.
A polyethylene pipeline is connected to the ejector unit, the length of which should be equal to the sum of the distance from the depth of the well and the pump to the wellhead (minus 1 meter).
Then, a 90° elbow is mounted on the wellhead.
Plastic pipelines are pushed through the straight elbow, which lead to the ejector assembly (finally, the space between the pipelines and the inside of the elbow can be filled with mounting foam).
The ejector device is lowered to the required depth. The correctness of the depth can be verified by the mark that was previously made on the pipeline.
At the top, a homemade head is fixed, consisting of a knee rotated at an angle of 90 °. The head is fixed on the well casing by means of a specialized one for plumbing.

Connection to internal water supply

Pumping station for a private house: connection diagram to the internal water supply system.

A HDPE pipe from external networks (from a well or well) enters the building and ends with a brass fitting with a transition to a diameter of 32 mm.
The connections located before the fine filter have a diameter of 25 mm. A tee with a drain cock is connected to the brass fitting (when replacing or repairing water supply elements). Next, you need to turn towards the station. This will require 90 degrees.
After the corner, a quick coupling with a ball valve is installed. Next, a coarse mud trap is installed) to protect against sand, small stones, etc.
If a scheme is provided for connecting a pumping station to a well, then the filter should be installed in the well in front of the relief valve. In the case of pumping equipment, a brass manifold for a pressure gauge, a damper tank and a pressure switch departs from the well. For the first option, the collector is not required due to the fact that the pumping station for the water supply of the house is equipped with a tank and a pressure switch. If a pump is provided from the well, then the pressure switch is mounted in the collector in a horizontal position from above, the damper tank is connected from below, the fine filter is connected to the remaining connection.
After the filter, a transition to a polypropylene pipeline with a diameter of 25 mm is installed. For hot water supply, products reinforced with fiberglass are used, for cold - unreinforced. Pipelines are joined end-to-end after hot softening (soldering) using a special soldering iron.
Then a cold water collector is installed, and locking devices are mounted on the pipelines in case of repair.

Connection with storage tank

The connection scheme for a pumping station with a storage tank is used when the volume of water is insignificant or the debit of the well (well) is small. The storage tank is installed between the water source and the end user. The volume of the tank, depending on the daily consumption, can be from 300 to 1000 liters. In urban conditions, the daily volume of water per person is taken from a consumption of 170-250 liters, in the absence of a bathroom and in country conditions - 50-75 liters.

The connection diagram of a pumping station with a storage tank has the following advantages:

In winter, the storage tank does not require additional heating.
The storage tank does not take up space in the house.
Large tanks are allowed.

For underground installation, it is necessary to use storage tanks of a round or ribbed shape, which will ensure a high-quality connection of the pumping station to the well. The connection scheme using a storage tank is a cascade of separately controlled pumps.

In terms of living conditions, private houses have always lost somewhat to apartments in multi-storey buildings. This mainly concerned communications, which were not present in all buildings. The problem of water supply was especially acute. Modern man fights this with the help of a pumping station.

These units are sold assembled or assembled independently. Any owner can install a pumping station, you just need to figure out what kind of unit it is, how it works and where it is installed.

What you need to know to choose a pumping station

The station should be chosen based on your needs. There are two important selection factors:

technical characteristics of the pumping station,
well features.

The technical characteristics include the performance of the unit. It should give such a pressure of water that can cover its consumption both in the house and in the adjacent territories.

Practice shows that if it is necessary to install a pumping station in a country house or in a residential building where 4 people are constantly located, it is rational to opt for medium or low power devices. Such stations are equipped with a hydraulic accumulator with a volume of 20 liters. The productivity of the station is 2-4 m 3 per hour, the pressure is 45-55 meters. This is enough to cover the needs of a family of four.

When evaluating a well, it is necessary to take into account the following indicators:

productivity;
the size;
water level when the pump is off;
water level when the pump is running;
filter type;
pipe width.

How is the pumping station

The general design of the station includes either a storage tank or a hydraulic accumulator. The unit with a storage tank is an outdated option, it has many disadvantages. Firstly, the tank itself is a rather voluminous structure. Secondly, the water level and its pressure are controlled by a float, which is responsible for triggering the sensor when the water level drops, the sensor starts pumping. Flaws:

water leaves the system by gravity, so the output is low pressure;
the whole installation has large dimensions and is not always convenient for placement;
installation of the system is complex;
the storage tank must be installed above the station itself, which creates additional problems;
if the water level sensor breaks, it overflows over the edge of the tank.

Designs with a hydraulic accumulator are more reliable and practical. This unit is relatively small and easy to install. The system is supplemented by a relay that controls the ambient air pressure limit. It compresses it in a hydraulic accumulator under the pressure of water. When the pressure level reaches the required limit, the pump automatically turns off and water from the tank is supplied to the tap. As soon as the level drops, the pump starts to work again, until the required level is established.

Not only the device of the station differs, but also the pump itself. This is the device:

with built-in ejector;
with a remote ejector;
without ejector.

The principle of operation of the ejector - water is supplied from the well due to the created vacuum. These modifications have a slightly higher cost, but they do not raise water from 9 m, like classic stations, but even from 20 or 45 m. Ejector pumps are very productive, there is only one drawback - they create a lot of noise during operation. This drawback is smoothed out by installing a pump with an ejector outside the living quarters.

Pumps with a remote ejector are convenient in that the pump itself is lowered into the place of water intake. Water is supplied to the ejector through a pipe in which a suction jet is created. According to the characteristics and further operation, this design loses to pumps with a built-in ejector. If air or sand is present at the water intake, this leads to a quick breakdown of the pump. The advantage of a station of this design is that it is easy to place it in a house, even at a distance of 20-40 m from housing.

Pumps without ejectors deliver water a little differently. In such an apparatus there is a complex multi-stage design, which refers to the hydraulic part. An ejectorless station works without noise and consumes less electricity.

These three types of pumps are the main ones, they are most often used in residential buildings. However, there are many other types of pumps, on the basis of which the pumping station is installed.

Location of the pumping station

The pump is installed in the house or in the caisson. A caisson is an equipped recess in the ground. The caisson for the pump is protected from moisture, groundwater and low temperatures. Equip it under the line of soil freezing. This option has a couple of significant drawbacks. Firstly, it is the need to equip this room for the pump. Secondly, it is quite difficult to insulate it in a harsh climate, and under the influence of low temperatures the pump fails.

The equipment of a pumping station in the house is the most practical option. The best location is the basement. It is necessary to take into account only one factor - the probability of flooding the basement with groundwater. If during spring floods it is filled with water, the station must be placed on an elevation where it will not be accessible to moisture. During installation, the station should not touch the walls in order to avoid unnecessary vibrations from its operation. The basement also monitors the temperature of the room at any time of the year to protect the station from frost.

When choosing an installation site, consider the following factors:

distance from the place of water intake to the station;
humidity and temperature at the place of its installation;
the availability of free space for the convenience of performing repair and maintenance work;
isolation of station operation noise from living quarters.

Algorithm for installing a pumping station

Do-it-yourself installation of a pumping station consists of the following steps:

Digging trenches for pipes, it should have a slope relative to the place of water intake.
Pipe passage equipment in the wall of the house.
Laying pipes in a trench.
Connecting pipes to the pump.

Useful advice: you should pay attention to groundwater, if they are high, then the pipeline is laid above a critical level. Pipes are insulated from low temperatures.

The pump is installed on a special base. The legs are screwed to the base with anchors, this will give the entire system a stable position. Also, to dampen vibration, a rubber mat is placed under the pump.

How to install a pumping station with a remote ejector:

Mount the ejector. It looks like a cast iron assembly with outlets for connection, there are three such outlets.
In the lower section of this assembly, a coarse filter in the form of a grid is attached.
A sling of the required length is selected, it is attached to a plastic socket at the top of the assembly.
Sgon has two parts, each of which contains adapters. It must be assembled to the required diameter.
A bronze sleeve is put on the outlet of the drive, it makes the transition to a polyethylene pipe.
To ensure the tightness of all connections, flax or sealing tape is used.
Further laying of pipes and digging trenches, they are dug below the level of soil freezing.
Pipes are laid in ready-made trenches, they are taken with a margin. For the casing pipe, a head or elbow with a smooth angle is used.
The pipe and the ejector are connected by means of a coupling.
The lower end of the tube is put on the knee at a right angle, and then lowered. All free space is sealed with mounting foam. The pipe is attached to the 90° adapter and to the pipeline.
The assembled ejector is lowered to the desired depth at the place of water intake. This value is marked at the beginning of all work, the mark is indicated at the level of the casing.
The head is strengthened on the casing pipe, for this purpose reinforced plumbing tape is used.

Errors to avoid when installing a pumping station:

When installing pipes, all values \u200b\u200bmust be taken with a margin. Often, during installation, all bends, turns, and the thickness of the foundation are not taken into account if the station is installed in a house.
Tighten all parts only with a wrench, hand-tight and insulated connections may leak.
The hydraulic accumulator must not be left unattended. If the pressure indicator is below 1.2-1.5 atmospheres, it is increased using a compressor or a car pump.

How to connect the station to the water supply

The need to connect the pump to the central water supply system may arise for various reasons. Often this is the imperfection of the plumbing system and low pressure in it. The installation scheme of the pumping station to the water supply system looks like this:

In the selected place, the water supply pipes are disconnected and connected to the storage tank.
From this tank, water is supplied to the pumping station.
From the pump, the pipe is diverted to the place of water supply.
Electrical wiring is being installed.
The pump is adjustable and adjustable.
The equipment setting is the adjustment of the optimal pressure in the system.

About 2 liters of water are poured into the snail and they monitor how much the pump turns off and on. The optimal indicator for turning off is 2.5-3 bar, turning on is 1.5-1.8 bar. To adjust the pressure, use a screw with the designation "DR" or "P".

How to install a pumping station, a video on this topic tells in detail and clearly. Also, each manufacturer supplies its pumps with diagrams and detailed instructions. The general installation algorithm is suitable for all units, but there may be some nuances and deviations that must be clarified before connecting.

To install or not to install a filter for a pumping station

An important factor that should be taken into account when connecting the station is the chemical composition of water and its physical qualities. Harmful impurities are contained in water from any source; they cannot be allowed into the pumping station. To eliminate this problem, the device is equipped with a filter.

The filter prevents the accumulation of mechanical impurities in the accumulator and increases the life of the pump. This is the undeniable advantage of filters.

There are negative sides in the installation of the filter. Firstly, it creates additional resistance to the flow of water, reduces head and pressure. Secondly, a dirty filter can completely block the access of water to the station and disable it. To avoid these troubles, the cleanliness of the filter must be monitored very carefully. In general, installing a filter is just a necessary event.

Common malfunctions in the operation of the station and their elimination

The pump rotates but no water enters the system. The reason for this malfunction is the depressurization of pipelines, and this situation also occurs due to incorrect operation of the check valve, lack of water in the system. To fix this problem, you need to check the presence of water in the system. If there is no water, it must be added through a special hole at the station or change the depth to which the pump hose is lowered. If the problem persists after this, check the valve and all connections for tightness. If this does not help, then it is necessary to check the health of the pump itself.

The pump turns on very often and runs unevenly, jerkily. Most often, the cause of such a malfunction is damage to one of the parts of the hydraulic tank. There is a nipple on the back of the tank, if water flows after pressing it, then one of the pump membranes is torn and it needs to be replaced. Also, the cause of the malfunction may be depressurization of the housing. If the described malfunctions are not found, then pumping air into the tank using a conventional pump can help solve the problem.
The pump does not start. Often this happens due to a lack of power. To eliminate the cause, it is necessary to check the winding and contacts on the pressure switch.
The pump turns on but does not rotate. The reason is a breakdown of the condenser, the impeller stuck to the pump housing. Often this situation occurs after a long break in the operation of the pump. To eliminate the impeller, it is necessary to scroll manually several times, but if this does not help, then the capacitor is broken and it needs to be replaced.
The pump operates continuously, does not pause in operation. The cause of this failure is a malfunction of the control relay. It must be adjusted using two springs located on the relay itself. The larger one regulates the minimum pressure, the smaller one controls the difference between the lower and upper readings. Also, the cause may be blockages at the inlet of the relay. All work with this part of the pump must be carried out very carefully.

Pumping stations are mounted wherever there is no way to connect to the central water supply system. In such situations, they become the only reasonable way out. However, it is not enough just to buy a station, it still needs to be properly mounted and connected to.

This article will discuss in detail the connection of the pumping station, its stages and important nuances. Advice will also be given on its choice, and reviews of people with many years of experience in using this equipment will be given.

1 What is a pumping station made of?

Well pumping stations consist of the following functional elements:

In the arrangement of do-it-yourself pumping stations, two types of pumps are most often used for water intake - vibration pumps (such as "Kid", "Brook", and the like), or centrifugal units. It is worth choosing a vibration pump if water is taken from a shallow source - a well, or a sand well, the depth of which does not exceed 10-15 meters.

The advantages of vibration devices include minimal cost, simple repair, and sufficient productivity for undemanding domestic use.

However, if you own an artesian well that is over 30 meters deep, you will need a submersible centrifugal pump. Such units are an order of magnitude more expensive, but their power and service life are incomparably higher than those of the pumps "".

Surface pumps are also often used, but they have a relatively low possible water intake depth (about 12-15 meters), and therefore are not suitable for use inside deep wells or wells.

Hydraulic accumulator

A hydraulic accumulator for pumping stations is a container that performs the function of water accumulation. In addition to the fact that the house will always have the required amount of water, such a tank will protect the entire system from water hammer and ensure the optimal operation of the pump.

2 What is important when connecting pumping stations?

Now that we have figured out the design of pumping stations, let's turn to a detailed study of the specific stages of its installation.

2.1 Stage number 1 - choose a place

The installation of a pumping station begins with determining its location. There are two options, each of which has its own advantages and disadvantages: in a borehole caisson, or in the basement of a summer residence.

Installation in the basement of the cottage.

If you have the opportunity to install a pumping station in the basement of the cottage, then you need to use it. Since, due to the fact that the station is always at hand, you can constantly monitor its operation, and, if necessary, carry out repairs yourself.

In addition, the basement of the cottage, even in the coldest season, will have a higher temperature than even a well-insulated caisson, which allows you not to worry about the possible freezing of equipment. The place inside the cottage for the station must be selected taking into account the fact that the equipment during operation will create quite serious noise.

Installation in a caisson.

The caisson, in most cases, is planned at the well design stage as a future reservoir for pumping stations. This is the best option for those who cannot install it in the basement of the cottage, or in any other room, due to lack of free space.

2.2 Stage number 2 - laying the pipeline

When equipping the pipeline, it is necessary to take into account the fact that the water supply of the cottage will be carried out all year round, and therefore it is necessary to ensure that the pipes do not freeze in winter.

There are two options for solving this issue: the first is to dig a trench for pipes with your own hands to a depth lower than the level of soil freezing; the second -, this can be done with mineral wool, or any other similar insulation.

As practice and reviews show, it is better to combine these two options - only in this case you can be sure of the effectiveness of insulation. Direct laying of the pipeline is carried out in the following sequence:

2.3 Stage No. 3 - work with submersible equipment;

If you want to install a ready-made industrial pumping station in which the capacity of the accumulator is combined with a surface pump, then you need to prepare a water intake pipe that will go down into the well. With your own hands, it can be made from a piece of an ordinary polymer pipe.

To do this, on the lower section of the pipe we install (a metal mesh with a small mesh size), which will perform the primary filtration of water from the main mechanical impurities.

Also, it is necessary to install a check valve on the bottom of the water intake pipe, it will not work to make it yourself - it is purchased in specialized stores, at a price of one hundred to five hundred rubles. After completion of the preparatory work, we connect the pipeline to the water intake pipe, and place it inside the well.

2.4 Stage 4 - installation and connection of the station

Having chosen the site of the dacha on which the pumping station will be connected, you need to take care of its preparation. The station itself must be mounted on a special base - a low platform made of wood, brick, or concrete, the main thing is that it dampens vibrations (for this, it is necessary to lay a rubber mat on its surface) and be stable.

The equipment on the base is fixed with anchor bolts. After fixing the equipment to the station, it is necessary to connect the pipe coming from the well. To do this, you will need a coupling with an external thread, a corresponding pipe corner, a check valve, and a stopcock. Having connected all the details, we proceed to connect the station to the water pipes of the dacha.

We do it in the same way: a shut-off valve is installed on the pressure pipe of the station, a coupling is connected to the valve, into which a plastic pipe is soldered. The presence of shut-off valves at the inlet and outlet of the well is required so that in the event that equipment needs to be repaired, you can quickly turn off the water and disconnect the unit with your own hands.

2.5 Stage number 5 - checking the health of the system

Before starting the station for the first time, it is necessary to prefill the pump and . After turning on the equipment, make sure that the pressure indicator on the pressure gauge is within the normal range, which is individual for each pumping station (usually 1.5 - 3 atm.)

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.

To solve the problem of water supply, many owners of private houses use pumping stations.

These devices are now available for sale ready-made or can be purchased separately. Moreover, it is within the power of each person to complete the installation of a pumping station in their home. The main thing is to know what elements this device consists of, how exactly it works, how to start the pumping station and where it is better to install it.

What you need to know to choose a pumping station?

In order for the selected station to cope well with its functions, the choice must be made taking into account your needs. In this regard, it is possible highlight the following criteria, which should be taken into account by the owner in the first place:

Technical characteristics of the pumping station;
Well features.

Considering the technical characteristics, first of all, the performance of the unit should be highlighted. The best option is a device that can provide water pressure from a well, which can satisfy the needs directly in the house, as well as in the adjacent areas.

Based on practical experience, we can say that for normal living in a country house or a residential building designed for 4 people, it is recommended to choose a device medium or low power. In the design of such units there is a hydraulic accumulator with a volume of 20 liters. Such a station is capable of supplying water from a well in the amount of 2-4 cubic meters. meters per hour and a pressure of 45-55 meters. An installation with such characteristics can fully meet the needs of a family of four.

In the process of considering various installations, one should also take into account a number of other important indicators:

productivity;
the size;
water level when the pump is off;
water level when the pump is running;
filter type;
pipe width.

In any station there is such a mandatory element as storage tank or hydraulic accumulator. It is worth saying that the installation with a storage tank is an outdated design due to the presence of a large number of shortcomings. First of all, the tank has a fairly large capacity. In addition, a float is used to regulate the water level and its pressure, which ensures that the sensor is triggered in the event of a drop in water level. In this case, the sensor sends a signal to turn on the swap.

The main disadvantages the following can be named:

The water supply to the system is carried out in a natural way, due to which the pressure force at the outlet is insufficient;
Due to the large size of the unit, it is not always possible to find a suitable place for its installation;
The process of installing the system is accompanied by certain difficulties;
For the storage tank, it is important to allocate space at the station itself, and this is fraught with additional problems;
In the event of a failure of the water level sensor, it overflows over the edge of the tank.

Installations equipped with a hydraulic accumulator have the greatest reliability and practicality. Their popularity is due small dimensions and the absence of difficulties in installation. The system design contains a relay that performs the duties of regulating the ambient air pressure limit.

Due to the creation of water pressure, it is compressed in the accumulator. At the moment when the pressure reaches the required limit, the pump automatically turns off, as a result of which water from the tank enters the tap. In the event of a decrease in the level, the pump is switched on again and continues to work until the desired water level is again provided.

For the pump, you can choose a place directly in the house or caisson. The last option is structure built in the ground. This design provides it with protection from moisture, groundwater and low temperatures. It must be built under the line of soil freezing. However, this option has several downsides. First of all, such a structure requires competent arrangement. In addition, in areas where harsh climatic conditions are observed, it is difficult to insulate the caisson, as a result, when exposed to low temperatures, there is a risk of pump failure.

The most practical solution is to install a pump in the house. It is best to install it in the basement. However, one important point must be mentioned here: one should be prepared for the fact that groundwater can create basement flood risk. Therefore, during the period of spring floods, when the room is filled with water, it is recommended to install the station on a hill so that water does not reach it. You need to choose a place for the station so that it is removed from the walls, which will prevent excessive vibration during operation. When placing the pump in the basement, it is necessary to constantly monitor the temperature regime throughout the year in order to protect the installation from the effects of negative temperatures.

Seat selection rules

To select a suitable place for a pumping station, the installation in which should take place in accordance with the technology, you need proceed from the following criteria:

The distance at which the station will be removed from the well;
Temperature and humidity conditions in the place chosen for installation;
The presence of free space so that you can easily engage in the repair and maintenance of the unit;
Carrying out work to isolate the premises in order to limit the spread of noise in the direction of residential premises.

To properly install the pumping station with your own hands, you need stick to the following order doing this job:

A prerequisite for the installation technology of the pump is its accommodation on a special basis. The legs must be fixed to the base using anchors. As a result, it will be possible to provide increased stability of the structure. To minimize vibration, the pump must be mounted on a rubber mat.

Do-it-yourself connection of a pumping station in a private house with remote ejector is performed according to the following algorithm:

Mounting errors

During the installation of the pumping station, there is risk of making mistakes:

Conclusion

The owners of private houses solve the problem of water supply in a slightly different way than the owners of city apartments. Having a pumping station in the house, they can always use water in the required quantity by connecting it to the well. However, for this you need to correctly install the pumping station in a private house with your own hands. By itself, the process of its installation does not seem so complicated, but here there are certain nuances, which most often do not know many owners. Therefore, it is necessary to carefully approach the study of the main points of the station installation technology, while performing preliminary calculations.
