Selecting the water supply pipe for the submersible pump. How to connect a deep pump: stages of work

04.04.2019 All about grapes

In order to provide vacation home or the cottage of the required amount of water used for household needs and for watering green spaces on panstoneThe source of water supply is needed, which can act as a well or well. If the solution of issues with the arrangement of such a source is best to entrust qualified and experienced specialists, then the installation of the pump in the well, which will pump out from it, can be performed independently.

How to install the pump in the already prepared well? First of all, you need to purchase a device, specifications which corresponds to the parameters of the straightening autonomous water supply system. Only if the pump is properly properly, and the installation of the pump in the well was performed properly, one can count on the efficient and smooth operation of such a device for a long period.

How to install a pump in the well and perform commissioning work

After drilling the well, the casing is installed in it, in which the deep pump is lowered. Before starting to install the deep pump in the well, you should make sure that all over the inner surface of the casing tube there are no narrowings and curvature, which can not only make installation, but also significantly reduce the operation of the pumping equipment.

Before installing submersible pump In the well, determine the difference between the inner diameter of the casing and the outer diameter of the hydromachine housing. If such a difference is too small, then all defects existing on the inner walls of the casing will adversely affect the operation of the device. If the gap between the pump housing and the pipe walls is too big, it may cause equipment output. The water that the deep pump pumped out of the well should move with sufficient speed in order to ensure efficient cooling of the pump, so when installing the gap between its body and the inner walls of the casing must have an optimal value. Such a value is usually indicated in a technical passport for each submersible pump model.

The installation of the submersible pump in the well is carried out using a polyamide cord that is tied to the hydromachine housing. When choosing such a cord to install the pump in the well with your own hands, it should be borne in mind that this product must withstand the load on the gap, the value of which at least five times the weight of the pumping equipment installed. To exclude the risk of absorption into the inner part of the node hydromachine, with which the polyamide cord is attached to its body, such a node should be tied up at a distance of about 10 cm from the inlets of the device, and the ends of the cord are melted.

If the depth of the well, into which the deep pump is mounted, does not exceed 10 meters, then in addition to the polyamide cord, when the pump is installed, it is necessary to use a spring suspension that is used to the device body. As such a suspension, which is necessary in order to extinguish the vibration of a working submersible pump, you can use a medical harness or tape made of flexible rubber. However, it is impossible to use wire or cable made of metal in this function. This is explained by the fact that elements of such suspension distinguished by high hardness can simply break the fasteners on the pump housing.

The installation of a deep pump assumes that together with the hydromachine itself, the installation of which in the well is performed using a polyamide cord, the power supply cord and metal-plastic pipe connected to the injection pipe are lowered into the casing tube. All three levels in the well, along with the pump of the element (polyamide cord, power cord and pipe) are sealed with an insulating tape, while the step with which such mounts are performed may be in the range of 70-130 cm. Place the first bundle connecting Polyamide cord, pump power supply and pipe, follows at a distance of at least 20-30 cm from the injection pipe.

Since threaded compounds reduce pipe strength indicators, borehole pump try to install without their use. As a rule, the installation of the submersible pump in the well is carried out using flange-type compounds, which are characterized by high reliability and durability. The fastening bolts in the connections of this type are inserted through the upper flange, and the nut is screwed down to it. The need to comply with such a recommendation is due to the fact that if the bolt rejuvenated to fall into the mine's mine, he will cause much more harm to it than the nuts falling into it.

Before installing a borehole pump, you should first measure at what depth in the underground source is water. To implement such a measurement, a column of gas pipes is used, descended into the well mine through the hole in the support plate.

You should also know how to lower the pump in the well so as not to damage the device case during installation. Best of all, when lowering the pump in the well, put the rubber ring on its body, which will protect it from damage when attacking the wall of the casing. After the submersible pump is lowered into the well to the desired depth, the upper end of the suspension, on which such a device holds, is tied to a special crossbar fixed on the ground surface.

When equipping an underground water source with pumping equipment, it is important to know how to install a pump in the well, as well as how to connect such a device to the pipeline system, which it will serve. Installation of a well pump, performed after the equipment is already on the required depth of an underground water source, are carried out according to the following algorithm.

The upper end of the pipe connected to the pump discharge nozzle is attached to the support plate, which is equipped with a well.
If a built-in check valve is not provided in the pump design, it is purchased separately for installation on the injection line.
In addition, it is necessary to install on the injection pipe of the valve, a tap knee and a pressure gauge, with which the fluid pressure will be measured.
After all of the above actions are made, it is possible to connect the knee, departing from the injection pipe to the pipeline by which water pumping out from the well will flow to the points of its consumption.

Before connecting the pump placed in the well to the power station and control such a device, it is desirable to measure the resistance to winding its drive motor and an electrical cable immersed in a liquid medium. You can perform such a procedure that completes the installation of a well pump with your own hands using a megaometer. After checking the pump, the pump is connected to the control station. Then execute a trial launch of installed equipment.

How to determine the desired source depth

Installing the well pump should be carried out at a certain depth of the water source. When used as a source of water supply, the well takes into account the static and dynamic levels of the arrangement in it with a pumped liquid medium. Under the static level, the distance on which the water mirror is in a calm state is located on the surface of the Earth. At dynamic level, water in the well is after it is started to pump out.

Submersible pumping equipment so that it efficiently functioned and was highly cooled by means of a liquid medium pumped by them, it should be placed in a well at a rate of at least 30 cm below the dynamic level. If the thickness of the aqueous layer allows, it will be better if the installation of the deep pump will be performed at a mark below the dynamic level by 2-3 m. It should be borne in mind that the pump installed in the well must be at a distance of at least 1-2 m from her bottom.

Dismantling of the deep pump

The need for dismantling, carried out due to the output of the pump, may arise for a number of reasons, the most common of which are:

incorrectly installed submersible type pump in the well;
incorrectly selected elements of automatic control of pumping equipment;
incorrect selection of the hydromachine itself by its power.

So, if the pump initially designed to maintain wells with a depth of no more than 50 m, is used to raise water to a height of about 80 m, then repairing such equipment may be required after several months of its operation. Automatics of this pump, configured to a certain pressure of the pumped liquid medium, simply will simply not periodically turn off the device, as a result of which it will work with constant overloads and, accordingly, will quickly fail.

The townspeople with great joy change to registration: to become a resident of a country village and nice, and prestigious and useful for health. True, such a change of habitat means that interruptions with electricity and walking with a bucket of water for most of the immigrants will become familiar realities. You can put up with this, but you can fight. To buy and install the same generator, you need quite some time. But everything is much more complicated with the source of water. Himself look for a place for the well difficult, and digging it is generally dangerous for life. It is best to contact the specialists who will make this work for you. They will say whether it is possible to drill and install the pump in the well on the plot, if this option is more suitable for you.

Mounting and commissioning rules

Before installing the pump in the well, you need to check whether there are no irregularities, curvatures or essence of the casing. All this can not only significantly complicate the installation, but also reduce the service life of the equipment. If the difference in the diameters of the pipe and the pump is too small, all surface defects will affect its work, if the pump can be burned too much. The fact is that in the latter case will not be ensured by the speed of water, which is necessary for cooling the engine. The minimum allowable values \u200b\u200bmust be specified in the technical documentation.

The pump is suspended on a piping cord that can withstand the load on the gap, which is five times higher than its weight. To avoid suction of the node on which the suspension is fixed, it is tied at a distance of at least 10 centimeters from the inlets, and its tips are melted. If the pump is lowered less than ten meters, by the end of the cord you need to attach an additional spring suspension to repay the vibration. It can be a medical harness or tape of flexible rubber.

It is impossible to use iron wire or a cable as a suspension, since they are broken down on an aluminum pump housing.

Power cord, a kapron suspension and a metal-plastic pipe fasten with a tape with a step of 70-130 centimeters. The first bunch must be at a distance of at least 20-30 centimeters from the pump nozzle.

The pump suspension is selected with such a calculation so that it can withstand the load, which is 5-10 times higher than the weight of the pump. And the attachment assembly should be ten centimeters from the inlets

Connecting the pump to the well does not involve the use of threaded connections. They reduce the strength of the pipes, are subject to corrosion. Flaband compounds will last much longer. When using them fastening bolt. It is necessary to insert from above, and the nut is from below, since the bolt that fell into the well can lead to a serious accident.

The upper end of the injection pipeline is attached to the support plate. Then the check valve is installed on it (if it is not on the pump), the valve, knee, pressure gauge and connect the equipment to the water supply system.

Next, the suspension should be attached to the crossbar. This is the last thing to be done before omitting the pump in the well. When lowering, it should not touch the walls. If this cannot be guaranteed, the case is better protected by a rubber ring.

The pump in the well is needed very carefully, avoiding contacting and blows about the wall. Just in case, a rubber ring can be put on the housing

In order to measure the water level in the well, the gas pipe column is installed in the opening of the support plate. It is immersed below the dynamic level.

The megohmmeter needs to determine the insulation resistance of the motor winding with the lowered cable. After that, the control station to the pump is joined, check whether it is immersed in water and evaluate the operation of the electric motor under load.

What depth can and need to omit the pump?

The static level is the length of the segment from the ground level and to the water mirror in the natural state. Then the water begins to pump water. The level on which water will stop are called dynamic.

The pump falls below the dynamic water level by two meters, and at least one meter should remain to the bottom of the well.

In order for the engine to be cooled properly, the pump is needed to mark at least 30 centimeters below the dynamic level, and the optimal is considered a dive for two or three meters below this mark. It should be remembered that the distance to the bottom of the well should be at least 1-2 meters.

How to replace the pump in the well in case of an accident?

The need to replace the pump arises rarely, mainly due to the fact that the pump is incorrectly performed in the well. The reason for the accident can be in incorrectly selected power automation, and in the low power of the pump itself. For example, if it is designed for a 50-meter immersion, and in fact set to a depth of 80 meters, then the repair will be needed in a few months.

Automatic nutrition is configured to working, and from such a depth weak pump simply cannot raise it. As a result of constant work without a shutdown, it breaks quickly.

As in any situation, there are two outputs here: we call for repair professionals or do everything yourself.

Option number 1: We call specialists for the repair of deep pumps

First of all, this option is suitable for those who do not understand the pump equipment. Professionals can objectively assess the situation, identify the reasons that led to the malfunctions in the work of the equipment. Perhaps only the power automation works incorrectly, and the pump itself is in working condition. In this case, it is enough to properly configure.

Another plus for those who have already decided that such repairs he is not under power, this is a guarantee that the contractor gives. Also, in addition to basic work, you will fully configure the entire water supply system. Of course, for such services you need to pay, and if we are talking about the replacement of the pump, then the amount will be impressive.

Option number 2: Replacing the pump with your own hands

Without the replacement of the pump in the well only in the event that you are confident in its malfunction. If there are doubts, it is better to contact the specialists.

One work is simply impossible to do this work, you will need help at least five more people: on a 100-meter depth of a pump with a cable and suspension weighs about 250 kilograms.

First of all, you need to prepare a plumbing tool, an electric soldering iron, a construction hairdryer, a heat shrinking clutch, scissors and consumables.

Then we turn off from the wellhead pipeline running into the house and the pump power cable. After that, we unscrew the protrack element.

When the pump is raised, it is necessary to use the Insurer Cable. If the pump is broken, it will be impossible to raise it, and therefore use the well in the future too

The pump raised on the surface is disconnected from the highway. We perform the inspection of the pump, if it is still in working condition, replace the connecting mechanism, coupling and check valve. Older, most likely, have already lost their work properties, so it is better to put new ones. If the former pump repair is not subject to install a new one.

power cable

New pump prepare for immersion, solder the power cable and secure the safety cable

Installing the deep pump in the well must be executed extremely gently. It is necessary to allow contact with the walls of the casing.

The pump in the well needs to be lowered very carefully - watch it not to hit the wall

Tighten the well headband, connect the fittings to the strapping and configure the automation in accordance with the specified parameters.

Configure the power automation in accordance with the specified operating pressure parameters

The most convenient option for organizing water supply on the country site is a well. The deep pump runs quietly, and if the installation and commissioning were performed correctly, then the next time to look into the well you will have to do not very soon.

The deep borehole pump creates the pressure, sufficient to raise water from a high depth (even up to 100 m) and implement it in the water supply system. Many models of pumps are designed for pumping water, including sand or clay impurities.

vibration;
centrifugal.

The first type is used for wells with a shallow depth. The price of such pumps is quite accessible, but the quality is low. Basically, the vibration pump is used to produce water in small volumes. For example, for seasonal water supply of cottages or household economy. One of the disadvantages of this type of pumps is the destructive effect on the walls of the well due to vibration.

Centrifugal pumps have greater performance than vibration. They can be used for water supply home day after day, all year. Models in which all parts are made of stainless steel are able to withstand the abrasive effect of sand and other impurities.

Almost everyone can independently connect the deep pump, regardless of its type. Consider the basic rules of connection, but first a few words about the use of hydroaccumulators.

Why do you need a hydroaccumulator?

The principle of operation of the deep pump assumes its inclusion at the time of decrease in water pressure in the water supply system. In this case, the frequent opening-closing of the crane leads to frequent inclusion of the pump. Even when the crane is open, the pump creates a pressure sufficient for automatic shutdown, so it can turn on and disconnected several times. The result of such a mode of operation: premature wear of the pump engine. That is why, to protect the engine from frequent pressure drops, the pump connection is carried out through the hydroaccumulator.

This device is a container separated into two parts with a special flexible membrane. In one part there is air, to the other - water. The working pump fills the part of the hydroaccumulator with water until the air located in another part balances the fluid pressure. When the crane is opened, the air pushes water. We also use hydroaccumulators in which the water drive is made in the form of a pear located in air filled with air.

The hydroaccumulator performs three tasks:

supports water pressure in the system at one level;
serves as a warehouse of water;
prevents hydrate in the water supply system.

Since the battery supports constant pressure, the pump turns on less often and is less wearing. The volume of the required hydroaccumulator is calculated based on the amount of water consumed. For a private house, 100 liters are usually enough.

General rules for connecting the deep pump

A diagram of connecting the deep pump is shown, in what order the connection of all parts is performed. The depth of groundwater slides determines the depth of the well. The minimum pump distance from the bottom of the well should be 1 m. The distance from the upper point of groundwater to the surface of the Earth is called a dynamic level.

In detail, the order of connection of the deep pump is presented in the photo below.

To ensure the possibility of winter use of the well, a special well (caisson) is equipped, the depth of which should be lower than the depth of the soil layer. The well pipe at the exit to the caisson is cut and connects with the pipe deployed in the trench. Thus, the trench for the pipeline is locked at the level of the lower border of the well (caisson), below the drainage depth. In the trench, you must lay two pipes: water and for the electrical wiring of the pump.

Committable filter installation rough Cleaning In front of the pressure regulation node with a hydroaccumulator. The water purification filter is also installed on the segment after the hydroaccumulator before serving it into the water supply system of the house, although it is optional.

The sequence of connecting the electrically conductives is performed according to the electrical diagram of connecting the depth pump. The pump control panel is placed in the boiler room. For the power supply of the pump, a water-loading cable (wire) is used, providing reliable grounding. The usual waterproofing wire is not suitable. The length of the wire is equal to the sum of the dynamic level of the pump plus the distance from the well to the boiler room.

The cable is soldered to the deep pump. Isolation is made using shrink hydromeflip. It is not recommended to perform a heat shrink independently, since the process is quite delicate. Excess the heat shrinking time is fraught with loss of elasticity and water resistance. Insufficient heat shrinking leads to incomplete hydraulic cable.

If the deviation from the rated voltage is high, then it is necessary to install a voltage stabilizer with a three-time excess of the power of the pump. It is desirable that the electrical connections spent a qualified electrician.

Connecting the hydroaccumulator to the deep pump is made through the pressure relay and pressure gauge. The passage of the five-party serves as a node of the connection between the feed, analysis, hydroaccumulator, pressure gauge and pressure relay. Factory pressure switch settings: Lower - 1.5 bar, upper - 2.8 bar.

If we assume a removal of watering, you can install an additional hydroaccumulator in the caisson, through which irrigation water will be supplied. It is possible to use one hydroaccumulator that adjusts the water pressure for watering and for home, and is in the well. But for the convenience of servicing and controlling pressure, it is better to place a hydroaccumulator in the boiler room.

Dead of the deep pump in the well

Connecting the pump to the water supply tube we carry out through the connection: Barrel + check valve + fitting. All threads are compacted by the FUM ribbon, with the exception of the transition of metal plastic. Here applies an adhesive paste plus linen palable.

After trimming the well, but in front of the pump, the lower part of the head and the rubber ring-seal are put on the pipe cutting pipe. All connections thoroughly seal to protect the system from leaks.

The descent of the pump in the well is carried out using a stainless steel cable with a diameter of 4-5 mm. The length of the cable is determined with a reserve of 2-3 m to secure it at the ends. One end of the cable fasten on the top of the pump, stretching through special holes. For strength, a rivet with a copper pipe is made, but you can use special clamps (no less than two). Clamps are carefully covered with a tape. At the other end of the cable also mounted clips or rivets.

The pipe feeding from the pump must be straightened on a flat surface. Then unwind the cable and also have on a flat surface. Also with a cable. The pump is ready for descent.

The cable and cable are fixed in the pipe every 1.5-2 m with the help of construction screeds. After the descent on the casing, a borehole headpoint is worn. It is possible a water hose, a cable and a cable to do in advance through the hole of the head, before descent. The headpoint will protect the well from garbage.

Confix the capacitor and check the pump operation. If the water rolls out, then you can cut the pipe near the head and connect it with the pipe laid in the trench for water supply to the boiler room. The connection is made through a clutch with a collet clamp.

Starting pump after assembling system

Connect the outlet. A warning lamp lights up on the control panel. Turn on the water supply in order to release air from the system. The pump begins to work, and water enters the hydroaccumulator. There should be noise of water.

After the release of the air, water begins to flow. Close the crane. Follow the testimony of the pressure gauge: the pump shutdown occurs after the pressure is injected 2.8 bar. Then let the water from the crane and check the pump work after the pressure is reduced to 1.5 bar. The pump is again in operation. So, the work cycle is repeated.

If you tightly connected the entire system, then turning on and off the pump will be carried out according to its settings. The pump connection is successfully completed.

Vitely the process of connecting the deep pump is demonstrated on the video:

Own plumbing on the household plot is a huge plus, because it does not require a large effort to produce water for watering or water supply at home. After adjustment in the courtyard in the courtyard or well, a system for lifting liquid, as well as maintaining pressure in the water supply on the way from the well to the house. Because of its simplicity in maintenance and unpretentiousness, submersible pumps are installed in the well, which are still called deep or well. From the title it becomes clear that the unit is completely in water and raises it to the surface. In this article we will tell about how to connect the submersible pump to the network and the water supply system with your own hands.

What do you need to prepare?

For uninterrupted feed, automation is needed, which will follow the water supply system and trouble-free operation.

The minimum set for water supply from the well or the well consists of:

deep pump;
check valve;
float with a sensor;
pressure switch;
tank hydroaccumulator;
electronic control unit.

Consider the assignment of these items.

The pump is the main power element that produces water lifting from the well. The check valve is a bypass membrane, which is installed directly at the output of the power unit, preventing the reverse outflow of the fluid from the pipe.

Float sensor - an element of automation that follows the water level in the well. It depends on its position, it will be given permission to start the motor or not. Also, instead of the float, an electrode level sensor is installed. The sensor connection circuit is provided below:

Pressure relay Another automation element directly controlling the start of the immersed unit and responding to a change in pressure in the plumbing.

The hydroaccumulator is a passive pressure support system in a pipe, smoothing sharp jumps and pressure drops. Works in a pair with pressure relay. Prolongs the pump resource, increasing the time and turning off the engine, by accumulating water into the tank.

We dealt with the elements of the system, let's talk in more detail about how to connect the submersible pump to automation.

The procedure for installing the water system

The location of the devices should provide access for maintenance and control of the operation mode. Be sure to provide ease of replacement of non-working parts. Combine about protecting against precipitation and freezing. To connect the submersible pump to the mains, it is necessary to use a special cable with WFP or KVV marking. Isolation of these wires is designed for long lasting in water, without loss of flexibility and insulating properties. The imported analogue has an Aqua RN8 marking.

We recommend connecting the borehole pump to electricity through it necessary to control the isolation of the device and cable included. After all, on time, the identified and eliminated problem is a saved budget and nerves of the head of the family.

To install the pump and put water through the pipes, we will need:

watercupping aggregate itself;
special tank - hydroaccumulator;
pressure switch, chosen under the tank of the hydroaccumulator tank;
uS coupling for connecting the pressure switch to the hydroaccumulator;
canguage coupling, to transition from size to size;
brass adapters;
fitting, plastic pipes, Fuma Ribbon.

As a rule, the installation and connection of the submersible pump begin to produce, starting with the strapping of the hydroaccumulator, the sets of equipment on it. All assembly stages are presented in order in the photo:

The first stage is the preparation process. In the second snapshot, the FUM ribbon produces a winding of a threaded connection. Next, we make the installation of an American connection, which allows you to further make a simple assembly and disassembly. On the fourth and fifth picture, it is shown to install a pressure switch and a pressure gauge for visual control of the process in the system. After this stage, the process of mounting the exhaust knee from PVC pipes to the tee with sensors is shown. On the eighth and ninth photo, the setting of the collet clamp and the pressure pipe is visible. The tenth picture shows the installed group connected to the water supply. Well, the last steps are opening and connecting to the relay unit.

If your system consists of one automation node, a pressure sensor, then on the terminals of this device indicate the Line input and the "Motor" output. That is, the entrance from the "LINE" socket and the connection of the Motor submersible pump. More advanced automation consists of electronic block.

The starting pump control unit provides uninterrupted water supply to the system, protecting the engine from dry stroke, reacting to the presence and water level around the pump. The block produces a smooth start and a smooth stop, extending the engine of the engine, monitors the mode of its operation.

Control block diagram:

The dry stroke is the operation of the engine without a sufficient amount of water or without it, which causes overheating of the engine windings, destruction of isolation, the failure of the motor. All because water in the deep pumps plays the role of the cooler, because It passes through it and cools the case.

Installing the pump in the well is the first step towards the arrangement of the autonomous water supply. After all, the water pumps the pump. And the performance of the autonomous system depends not only on the characteristics of the aggregate itself, but also on the method of installing the pump in the well.

Therefore, in this article, we will consider the installation process at once several varieties of pumps.

Pumps for wells are divided into surface and submersible options. The first are located above the water, and the second - in the water. Moreover, two hoses are departed from surface units: suction (it is immersed in water) and pressure (it is associated with water supply).

From the submersible unit, in turn, only one hose is departed - pressure. Since the place of the suction hose in the construction of the submersible pump occupies a special nozzle located in the upper or lower part of the case.

In addition to the installation method, the pumps for wells can also be classified as the type of design of the working chamber. And according to this sign, pumps are centrifugal and vibration.

The working chamber of the vibration pump is separated from the engine compartment with an elastic membrane, which vibrates, creating alternate loop and compression cycles. Therefore, the vibration pump is not afraid of a strongly ridden water, nor dirt.

The operating chamber of the centrifugal pump is equipped with a special node - the impeller, which the motor shaft rotates. As a result, water moves along pipes under the action of a centrifugal force generated by the impeller. Well, the pump itself needs and in the preliminary fill in the water of the working chamber, and in cleaning the flow of the flow. Otherwise, the impeller will be bored with sludge and sand or simply burns against friction about the wall of the delivered camera.

How to install a pump in the well?

The design differences described above also affect the performance of the aggregates, and on the methods of installing pumps in the well. That is, the submersible pump is mounted completely different than superficial. Therefore, below text we will look at both technologies separately.

Installation of the surface pump in the well

Surface pumps are mounted either indoors, or at the ledge of the well (in the caisson).

Thus, the installation of the surface pump in the well is implemented as follows:

The hose of the desired length is attached to the suction nozzle.
At the end of the hose, the check valve is mounted - a special fitting that prevents the water plum into the well after turning off the pump.
The reversal valve is fastened with a mesh filter that protects the pump and the valve from the possible penetration of the ral particles.
The hose supplemented with a filter and valve is immersed in the well on the desired depth.

However, the connection of the pump to the well can be equipped with an adapter. And in this case, the hose will be connected not to the suction pipe of the pump, but to the adapter fitting.

If a surface pump It is supplied with a remote ejector, the well introduced a more complex system consisting of two hoses - pressure and suction. And on the end of the suction hose, the check valve, ejector and filter are mounted. And the pressure hose is connected to the side fitter of the ejector (by removal).

Installing the submersible pump in the well

Submersible pumps are mounted directly in the well mine. Therefore, the diameter of such an aggregate must correspond to the dimensions of the casing. Moreover, the pump should not be included in the "Veritir" pipe - in this case he is simply "overheating" due to problems with the cooling of the engine compartment. However, in the passport of the device always indicate the minimum possible diameter casing tubes Well, guarantees the lack of problems with the cooling of the pump.

Well, the installation of the deep pump in the well is as follows:

The return valve is fixed on the pump nozzle - it will save the owner of the well from the need to control the filling of the working chamber of the unit, preventing the water plum after turning off the pump.
An additional cup-shaped filter is fixed to the suction pipe - it levels the threat of the hosted of the working chamber.
The injection hose is fixed to the reverse valve, along which the water will go up (from the well). The suction piping of this model is missing. The second end of the hose is fixed or to the hydroaccumulator, or to the inside of the adapter, with which the "output" is placed from the well.
Power cord ( electrical cable) Connect with an injection hose using special clips or polymer screeds. Wire, in this case, is not categorically recommended - it can "Pour" a cable or hose.
In the eye (brackets) in the upper part of the pump housing, a polymer rope is carried out (twine). The unit will hang in the well on this rope.
The resulting design should be omitted into the well. Moreover, the pump must support only the rope. Operate the bundle "Cable + Hose" - is strictly prohibited. However, before omitting the pump in the well, the rope can be connected with a bundle with the same screeds. In this case, you will have to stop the possible "recess" of the rope and pressure hose.

After the unit is immersed in the well on the desired depth, the rope is fixed on a special bracket, placed on the outside of the casing's tip.

What depth to lower the pump? The answer to this question depends on the depth of the well itself, the reliability of the filtering elements and the quality of the aquifer. Usually, the pump "hang" in the meter from the bottom of the well. However, a variant of the pump is also possible to the upper limit of the filter element of the casing.

However, in any case, you need to measure the depth of the pump immersion with its power and pressure. Therefore, ordinary pumps are immersed to 7-10 meters, the aggregates with an ejector - to a mark of 15-20 meters, and the depth equipment - to 25-40 meters.

How to replace the pump in the well?

Unfortunately, the pump may break, like any other mechanical device. And after breakdown, the pump will have to be removed from the well for repair. Well, in the most difficult cases, a complete replacement of the pump in the well, along with all filters and safety elements.

And this procedure looks like this:

The system is disconnected from the power supply and disconnect from the water supply.
The pump is pulled out of the well, winding the removed pressure hose and an electrocabel in the bay. Moreover, the procedure of "lifting" of the pump involves significant physical exertion. Therefore, in this case, it will have to use at least three, four people: two-three pulls, and one cuts the screed and wars the hose and cable.
After removing the pump, it is disconnected from the check valve, gets rid of the filter element and is repaired (in place or in service).
During the repair of the unit, free partners can explore the hose and cable, on the subject of integrity defects.

After cleaning and repairing the whole system is going, fixed with polymer ties and immersed on the old place.
