The principle of operation of the deep pump. The principle of operation and installation rules for surface pumps. How to choose a well pump
Unlike centrifugal units (see), screw pumps for wells are capable of pumping liquids with a high content of mechanical impurities. If we talk about organizing an individual water supply for a private household from a sand well, then such a pump would be the best choice, since the presence of sand in the water does not affect its reliability and performance.
Device and operation of screw pumps
It is easiest for a person far from technology to explain the device and principle of operation of a screw pump using the example of a conventional meat grinder.
Design features
As in a meat grinder, the main working part of the device is an auger (therefore, such pumps are often called auger pumps), enclosed in a rubber cage. But it is not connected directly to the rotating shaft of the engine, but with the help of a cardan transmission, which ensures their slight misalignment.
When the shaft begins to rotate, the screw connected to it makes a complex movement around its axis, which in turn also rotates along a circle whose radius is given by the eccentricity of the screw. As a result of such movement, cavities are formed between the turns of the screw and the cage, which constantly move in the direction from the suction hole to the outlet pipe.
The liquid that has entered these cavities is gradually injected into the chamber, from where it is forced out under pressure, and in the meantime, pressure is reduced in the receiving part of the pump, so water from the well rushes into it.
Note. In this design, there are no parts between which solid inclusions in the liquid could get stuck - they are carried out with it. Therefore, screw pumps for wells can be used for pumping contaminated water with a high content of impurities.
Depending on the number of screws, these devices can be single-screw or multi-screw. But in systems of individual water supply from wells, they are usually used with one screw.
To get clean output drinking water a coarse mesh filter is often mounted on the suction pipe of the device, which does not allow large particles of sand or silt to enter. If this is not enough, then the filters fine cleaning are already installed on the surface, most often in the technical room of the house. Which ones are determined after water analysis (see).
Maintenance and operation
A simple and reliable design guarantees consumers a minimum of costs and time for the maintenance of such equipment.
So:
- The pump screw and rotor are cooled by the pumped water, so it practically does not need preventive maintenance, which is very convenient, since for this it would have to be periodically taken out of a deep well and then reinstalled.
- But even if repair or replacement of some parts is required, the well-thought-out design of the unit will allow you to do it yourself, without resorting to the services of specialists and the use of sophisticated equipment.
- The long service life of such pumps is also explained by the absence of vibration during operation, despite the high power and high speed.
- They are practically silent, so even if the well is equipped in the basement of the house, the operating equipment will not create discomfort.
Note. If necessary, a screw borehole pump can be used to supply water from reservoirs and reservoirs, as it can work in any position - both vertical and horizontal.
Downhole installation
Submersible screw pumps are mounted in the same way as centrifugal and any others. They also have an elongated cylindrical shape with a suction hole in the lower part, an outlet pipe and lugs for a cable in the upper part.
A metal cable holds the device at a given level, and power is supplied to it through an electrical cable. A hose or pipe is attached to the outlet pipe, through which water is supplied upward.
Instructions for connecting and installing the pump:
- Assemble the device and make sure it works;
- Connect the pressure hose to the nozzle and tighten it with clamps in several places along the entire length with a cable so that the latter does not sag;
- Install float switch if it is included;
- Attach the safety metal cable. This is a very crucial moment: if the cable breaks, getting the pump out of the well by pulling it by the cable will be problematic and fraught with breakage;
- Carefully lower the unit into the well to the required depth. by making a mark on the hose or cable in advance;
- Fasten the cable to ;
- Connect the screw pump for the well to the mains and check its operation.
The device must not vibrate or make loud noises or thuds. If this is not the case, then somewhere you made a mistake or there are problems in the mechanism itself.
Popular models of household screw pumps
Screw pumps are produced by many domestic and foreign manufacturers.
Among the most common and popular among our consumers are the following brands:
- Aquarius (Promelectro, Ukraine). Aquarius submersible pumps are compact and high power, can be used to supply water from wells, open reservoirs and wells with an internal diameter of at least 10 cm. country house, irrigation and irrigation systems, as well as for pumping water from pools, reservoirs, flooded basements. The kit includes a synthetic cable for installation in a well or well.
- . These deep hole screw pumps made of stainless steel are also multifunctional and versatile. Are applied to the device of water supply of private houses, garden and farms. They have high power, can work smoothly for a long time, the thermal protection of the engine is built into the design.
- Unipump ECO VINT (Russia). These pumps are distinguished by their low price, high pressure and low productivity, which is the best solution for sources with a small flow rate - wells and sand wells. The absence of vibration does not allow turbidity to rise from the bottom of the well, even with a high content of mechanical impurities in the water throughput device is not reduced.
Conclusion
It is definitely worth giving preference to screw pumps in cases where the quality of the water in the well leaves much to be desired. You can do its cleaning after rising to the surface, but the auger design device will cope with the extraction in the best possible way.
After watching the video in this article, you will better understand how it works and what are its advantages over other submersible pumps.
If you want to have free water in any quantity on your own site, then you should start by drilling a mine to an aquifer. The second step will be the installation of a downhole pump in the well. It is the proper operation of such equipment that will guarantee high-quality watering of garden plants, the uninterrupted operation of a washing machine and dishwasher, a bathroom and a bathroom.
Deep well pumps have different capacities, sizes and other parameters. In this article, we will look at the main selection criteria. Installing optimal equipment will save you from many problems in the future and will give you confidence in the constant presence of H 2 O in your area.
General provisions
In order to successfully pump water from wells, wells or other bodies of water, there are the following types of pumps:
- Self-priming. Such equipment is installed on the surface and sometimes looks like a full-fledged pumping station. They do a good job with sandy wells that have a relatively shallow depth.
- Submersible. They have a large power, the volume of pumped liquid and the height of the pressure column. Structurally able to penetrate even very narrow shafts. Ideal for artesian wells.
Selection and installation
Since a deep well pump is the best fit, let's move on to the rules for choosing it. To do this, first of all, it is necessary to determine where the water supply is required and in what quantity.
Right Criteria
- pump performance. The amount of liquid it can distill in one hour.
- Head height. The force of the push of the liquid is selected in accordance with the depth of the mine and its distance from the house.
- Well debit. The actual volume of water that can be provided by an aquifer per hour of continuous supply.
In this regard, you should start choosing pumping equipment after you have completed the technical passport with all the necessary data.
It should indicate:
- Shaft diameter. What will determine the diameter of the submersible apparatus.
- Static and dynamic water levels. The first one is formed in case of idle time of the structure, and the second one - in case of its active use.
- The productivity of a well, which is measured by the number of cubic meters liquids for an hour.
- Mine depth. Significantly affects the required head height.
You should not purchase an overly powerful submersible pump for two reasons:
- Its price will be much higher, but why overpay?
- If its productivity is greater than the productivity of the well, then it will not have time to fill with water. Because of this, the operation of a “dry” run will follow, which, in the absence of special protection, will lead to a burnout of the engine.
Thus, we now know that the maximum power should not exceed the amount of water inflow. What affects the minimum?
Let's consider:
- Your family size. On average, one adult needs about 1000 liters per day. Multiply this number by the number of permanent residents and you will know your home's daily water requirement.
- Availability and area of the garden. Watering crops usually takes up to 2000 liters of the required liquid.
- The number of concurrently used consumption points.
Here is an approximate list of them with a standard flow rate, measured in m 3 / hour:
- washing - 0.7;
- bathroom - 1.2;
- bidet - 0.3;
- shower room - 0.8;
- dishwasher - 0.6;
- washstand - 0.3;
- washing machine - 0.8;
- bathroom - 0.4
So, in order to start the washing machine and fill the bath at the same time, you will need equipment with a capacity of at least 2000 m 3 / hour. But, do not forget that there may be a need at this time to wash the dishes and go to the toilet.
In addition to the power that we choose based on the capabilities of the well and the needs of the residents, it is also important to select the correct head height, which will require fluid supply.
We perform calculations as follows:
- We take the height of the house and add 6 meters to it.
- The resulting amount is multiplied by the coefficient of pressure loss in the process of moving through the pipeline. It is equal to 1.15.
- Now add the depth of the mine to the surface of the water surface. We take this value from the technical passport provided by the drilling company.
- Next, you should take into account the distance of the well from the building in need of water supply. It is generally accepted that 10 m horizontally equals 1 m vertically.
Suppose that the height of your house is 7 m, the depth of the shaft is 30 m, and the distance from the water intake points is 20 m. Substitute: (7 + 6) * 1.15 + 30 + 2 = 46.95. That is, a pump is required, the head of which is at least 47 m.
The most important is just the calculation of the height of the water supply than the power of the pump. Since it is rare when all points of water consumption are open, but a miscalculation with pressure can lead to a complete absence of H 2 O in the water supply system.
Tip: in case of an error in the calculation of equipment performance, it is recommended to install membrane tank.
With it, it will be possible to set the pressure level, which will avoid water hammer along with frequent engine starts and stops.
Mounting
How to install a submersible pump in a well? To do this, you will need the apparatus itself, a metal-plastic pipe of the required length, an adapter, a steel cable and an electric cable with waterproofing.
The installation instructions look like this:
- We fasten a special nipple to the pump outlet, sealing the connection with the help of "winding". It will serve as an adapter for the casing thread.
- Before fixing, we align the polyethylene pipe as much as possible with our own hands. This will allow you to lower the device most evenly.
- We connect the power cable. In this case, it is required to ensure waterproofing as best as possible using special corrugations or heat shrink tubing.
Tip: when buying equipment, immediately check the presence of the wire.
Because usually it is not included in the package and therefore it should be purchased separately.
- We tie a steel cable to the lugs specially designed for this, located on the pump housing. From above it can be attached to a winch mounted on a tripod. This will facilitate the immersion of the apparatus to a great depth and will immediately answer the question of how to get a deep-well pump from a well for Maintenance.
- Now we tightly tie the pipe, cable and cable together with special clamps so that we get one whole route.
- We lower the unit. The places where it clings to the walls are carefully overcome with rotational movements.
- We fix the position of the pump below the dynamic water level, but at a height of at least a meter from the bottom. This will prevent sand and other small particles from being sucked into the system.
- From above, we install a knee that directs the pipe towards the house and hermetically closes the shaft to prevent oxygen and precipitation from entering it, which contribute to the corrosion process.
- To the building we dig a trench with a depth below the freezing of the soil. Depending on the region, it can vary from fifty centimeters to one and a half meters.
- We connect to the water supply system at home and use clean and.
Conclusion
Supply the house with water. An equally important step is right choice and installation of a deep pump.
When choosing the power of the device, one should take into account the number of residents, the need for watering the garden, possible water intake points and the production capacity of the well itself. In addition to this parameter, the accuracy of calculating the required head height, which comes from the height of the house, the distance from it to the mine and its depth, is also important.
Installation work is not difficult if you follow the recommendations, and it is quite doable on your own. It is important here to make the correct route from the power cable, plastic pipe, steel cable and carefully load the equipment.
The video in this article will give you more information.
Choose the right equipment for you!
There are different types and types of pumps for wells, then you will learn more about them, and first we will find out why a well pump is needed. With the help of this device, water is raised from great depths.
To calculate the power of a pump for water wells, you can use the calculator for calculating the power of a pump for water wells.
There are three types of well pumps: submersible pumping equipment, surface well pumps, and manual pumps.
1. First pump type (submersible) for wells used to obtain water from any reservoir. It differs from other pumping equipment in that it is immersed in water and are in water. For the manufacture of such devices, only high-quality materials are used that are able to resist corrosion. According to the way they work, they are divided into vibration and centrifugal.
Vibratory pumps simple in design and do not require special maintenance, which attracts buyers. Also, this type of pumps does not have a high price, which is also positive quality vibration pump. Also in such pumps there are no bearings and other rotating elements, which are the most problematic in any mechanism, and require special attention. Due to the fact that there are no rotating parts in such a pump, this reduces its heating and prevents early wear.
The mechanism of operation of the vibration pump is not complicated. The basis of his work is the creation of a magnetic space, while passing through the coil of electricity. When electricity touches the winding of the coil, a magnetic field is produced that draws in a core connected to a rod, which in turn is connected to a rubber diaphragm. The diaphragm, in turn, bends, thereby creating a reduced pressure in the middle of the pump. Water enters the chamber, and then the springs begin to work. The diaphragm returns to its normal position, which creates an excess of pressure that closes the valve. Water enters the consumer through the outlet pipe.
A submersible vibration pump is an excellent mechanism for pumping water from any containers, for watering a vegetable garden and a garden, for pumping water from a flooded basement.
centrifugal view submersible pump for wells pretty famous. With the help of such a device, it is possible to extract water of different temperatures, various acidic and oily solutions. Such a pump consists of an engine, an impeller with holes for outflow and water supply is attached to its shaft. The work consists of transferring the energy of the wheel, which rotates, to the fluid, which is located between the blades. The centrifugal force helps the fluid flow into the body and creates a pressure difference. The operation of the pump does not stop, and it supplies water through the outlet pipe.
Also, these pumps are divided into: self-priming and normal suction, and they, in turn, are divided into single-stage and multi-stage. Self-priming centrifugal pumps are distinguished by the fact that their housing is located horizontally. They begin to work after the suction pipe is completely filled with air. A normally suction centrifugal pump must be filled with water before connecting to electricity.
Multi-stage differ from single-stage in that they are able to develop a high pressure, while the performance remains the same.
2. Second type - surface pumps for wells. They are perfect for gardens or country houses, easily cope with the supply of water to such houses. But, it is worth noting that such pumps do not pump water even with the slightest pollution.
This type of pump is located on the surface, and a flexible hose is immersed in a well or well. The depth at which water is able to accumulate is 9 meters. But if you need to increase the length, you can buy ejectors. Before starting work, the pump is filled with water. Also, these pumps come with automatic on and off. Such pumps are considered more profitable, since they use much less electrics, they have protection against overheating, and they cope better with pumping water.
3. Last well pump type - manual pumps. They are also used for pumping and moving liquids that do not contain abrasive components, as well as such units are capable of pumping liquids such as alcohol, edible oils, paraffin, fuel. It should only be noted that in no case do such devices pump ether or carbon dioxide sulfide! The maximum allowable temperature of the pumped liquid should not exceed +80 degrees.
With a non-return valve at the end of the water supply, the suction head of the hand pump for wells is up to 9 meters.
Such pumps are an excellent option for supplying water to the pipelines of large pumping units before turning them on.
The design of such a pump consists of its body, cover, wing, suction part, lever, four valves and a shaft. It works on the principle of rotating the wing with a hand lever so that all sides participate in the process of suction or expulsion, due to which the movement of fluid occurs indefinitely.
There are many different types of hand pumps for wells, which differ in their appearance, according to its technical indicators and scope. Some pumps are designed exclusively for transporting oils and fuels, while others are only capable of handling contaminated water.
Then the question arises, so which of all types of pumps is best suited for extracting water from wells. And, most likely, to solve this issue, the majority begin to go to the Internet and look for an answer to their question, but for a complete answer virtual information clearly not enough. So here are a few parameters by which it is best to determine the type and type of well pump that suits you. And so, when choosing, pay special attention to several points:
1. Marking the base of the borehole bottom. You can get such information from the passport of your well, which the drilling company should have given you.
2. Dynamic water level. This is quite important information that shows the well flow rate. The dynamic level is a segment from the ground to the water surface while the pump is running. The flow rate is the largest amount of fluid that the well delivers per unit of time. If a large amount of water remains above the pump after it has been running for 30 minutes, it means that the flow rate in your well is good.
3. The next item to pay attention to is the statistical water level. This is the distance that is obtained from the earth to the water surface. Before measuring the statistical water level, the water in the well should not be pumped out for some time. From the depth of your well, subtract the statistical level indicator and get the value of the borehole water column.
4. The last thing to pay attention to is the diameter of the pipe. Everyone can measure such an indicator, well, or turn to specialists for help.
The arrangement of a finished well begins with the selection of pumping equipment. It is the pump that performs the main function in the autonomous water supply system. To ensure an uninterrupted supply of water, this appliance must have the appropriate characteristics and design that is most suitable for specific conditions. Therefore, when choosing a specific model, it is important to know what types of borehole pumps are and the features of each of them.
Depending on the device and principle of operation, there are 3 types of submersible pumps that are most often used in wells:
- screw;
- vibration;
- centrifugal.
Screw pumps
A design feature of screw models is the presence of a spiral on the rotor and an internal thread on the stator. The principle of operation of the device is to lift water along a helical spiral as a result of the rotation of the rotor.
It is convenient to use this type of submersible pumps when a source is silted up or for pumping a new well, since its operation is possible in conditions of rather dirty water. However, low efficiency (about 65%) and impressive dimensions of powerful models do not allow them to be used for deep wells of small diameter.
Vibratory pumps
The operation of this device is based on the action of a vibrator associated with an electromagnetic coil. When an alternating electric current passes through the coil, an electromagnetic field is formed that sets the vibrator in motion. Thus, a pumping effect is created in the water pressure channel.
Advice. Vibration pumps are very sensitive to power fluctuations. For example, if the supply voltage is reduced by 10%, the head can drop by 50%. Therefore, for stable operation, it is recommended to connect the device through a voltage stabilizer of the appropriate power.
Given the relative simplicity of design, vibration-type pumps are reliable and durable. And the low price has made such devices quite popular in the private sector.
Centrifugal pumps
The most effective type of deep well pumps is a centrifugal device. An electric motor generates torque on a shaft, which is equipped with one or more impellers with blades. The higher the number of working bodies, the greater the productivity.
Interesting to know. Since the main load falls on the impellers, they are made of high-strength materials (noryl, polycarbonate, high-quality steel).
Such devices have a high efficiency (more than 85%) and are able to pump water from deep artesian sources. In addition, the small body diameter (3-4 inches) allows the use of such equipment in wells with a casing pipe diameter of 120 mm or more.
How to choose a submersible pump for a well
To choose the right device for the water supply system at home, it is not enough to know what types of submersible pumps for wells are. In addition, you need to take into account some technical parameters, namely:
- required height of water supply;
- the volume of fluid pumped per unit of time;
- device power;
- static (constant) well level;
- dynamic level during water intake;
- debit - a stable flow rate provided by an underground source.
Important. Usually, during the operation of the equipment, the drop of the water table is 3-8 m. In this case, the location of the apparatus must strictly correspond to the dynamic level of the well, not exceeding it.
Flow determination
One of the main parameters when choosing a type and a specific model well pump is the water consumption, which depends on the number of people permanently residing in the house and the sampling points (kitchen, bathroom, bathhouse, swimming pool, watering the site, etc.). With standard housing parameters without a bathhouse and a pool, the average consumption per person is 150-180 l / h. However, it is necessary to foresee the situation when several points of consumption are involved at once. In addition, a certain margin of instrument performance should be left. Therefore, the flow rate is usually selected at the rate of 300 l / h per person.
The water consumption parameter depends on the number of residents and points of consumption
Calculation of the required pressure
The head is determined using the following formula:
N \u003d U + V + D + 20%
Y is the dynamic level of the well;
B - the distance from the surface of the earth to the highest point of the fence;
D - pressure in the system (usually 1-3 bar, which corresponds to 10-30 meters of water column);
20% - compensation for friction losses in the riser pipe and the house's plumbing system.
Calculation example:
Calculate the required water pressure for a one-story country house with a dynamic well level of 40 m and the highest consumption point at a height of 2 m from the ground.
H \u003d (40 + 2 + 30) x 1.2 \u003d 86.4 (m)
If three people live in the house on a permanent basis, then the minimum flow should be 900 l / h. Taking into account this indicator and the head calculated earlier, a submersible pump for the well is selected with the appropriate technical parameters.
Important. The performance of the equipment should be selected taking into account the flow rate of the well. Otherwise, the water level will not be able to recover quickly, which will lead to frequent interruptions in water supply.
The stability and reliability of the autonomous water supply system largely depends on the type and characteristics of the borehole pump. Therefore, before the final choice, it is better to consult with experts who will advise the best model depending on the parameters of the well and the planned water consumption in your home.
Video: pump selection
Well drilling in the area near the country house is completed. The next question facing the owner is the choice of a pump that would be able to extract and transfer water to users as efficiently as possible. The best solution is to purchase a submersible pump for the well. This article will help you decide on the model and the main characteristics of the device.
How to choose a well pump
Water submersible pumps for wells are selected based on:
- device types that differ in the principle of operation;
- well parameters;
- equipment specifications.
Types of submersible pumps
How to choose a device that is most suitable for a well in a suburban area? First of all, you need to decide on the type of pump.
All submersible pumps according to the principle of operation can be divided into several types:
- centrifugal;
- vortex;
- vibration;
- screw.
A submersible centrifugal pump for a well works by creating a turbulent flow by rotating diffusers.
Centrifugal pumps are easy to use and require no special maintenance. The cost of the equipment is relatively small. However, the device also has negative aspects, which include:
- the need to install an additional filter at the bottom of the well. Centrifugal type pumps are very sensitive to the ingress of various impurities and / or small particles into the device;
- it is required to put the device into operation after filling the pump with water. Running the pump "dry" will damage the equipment.
One of the varieties of centrifugal devices are those capable of pumping both clean and slightly clogged water.
Centrifugal submersible pumps can be used for both deep and small wells.
The vortex-type submersible borehole pump raises water by mixing the air supplied to the chamber through a special pipe and the working fluid.
Vortex pumps are characterized by low power, therefore they are used only for shallow wells.
The principle of operation of the vibration pump is based on the movement of the rod due to electric current.
The advantages of the vibration pump are:
- reduced requirements for water quality. The device is capable of pumping water with minor impurities without compromising wear;
- high reliability achieved by simple design.
Along with the significant advantages of the equipment, there are also disadvantages of the device, which include:
- the vibration created by the pump negatively affects the walls of the well. If the walls are not fixed with specialized materials, then they are gradually destroyed;
- small working depth.
Vibratory pumps must not be installed below 5 m from the ground level.
A screw-type submersible borehole pump consists of a housing (stator) inside which a helical rotor rotates. When the rotor rotates, water is taken from the well and fed into the pipeline.
Screw pumps are capable of lifting water from a depth of 40 - 50 m, but due to the increased friction created inside the structure, the equipment requires periodic cleaning and replacement of working parts.
Screw pumps are mainly used for industrial purposes.
Well parameters affecting pump selection
The selection of a submersible pump should also be based on the parameters of the well, which can be obtained from the technical passport of the structure, issued after manufacture, or measured independently using a load and a long rope. The main parameters that matter when choosing a pump include:
- depth, defined as the distance from the surface of the earth to the bottom of the well. This indicator is necessary to determine the pressure of the device;
- the borehole diameter is needed to determine the diameter of the equipment. The pump should not touch the walls of the well, but should not have a too small diameter, as this affects the performance of the device;
The optimal diameter of the pump is 20-30 mm less than the diameter of the well.
- well debit. The indicator determines the volume of water that can be raised from the well per unit of time. The correct determination of the debit affects the choice of pump power. Exceeding power over debit can lead to "drying" of the water source;
- static and dynamic water levels. The statistical level determines the constant amount of fluid in the well. The dynamic level is calculated based on their constant consumption. These indicators are important to consider when choosing a pump for determining the level of immersion.
Definition of technical parameters
The technical characteristics of the pump, which should be paid attention to when choosing a submersible pump, are the following parameters:
- equipment performance. This parameter shows how much liquid the pump can pump in a certain unit of time. The capacity can be calculated in m³/h. The calculation of productivity is determined on the basis of consumption rates and plumbing fixtures installed in the house on the basis of consumption rates developed by specialists;
- the head that the pump can lift water. When calculating the indicator, the depth of the well and the length of the pipeline should be taken into account, and 10 m of length increase the height indicator by 1 m. To provide an additional reserve, it is recommended to increase the obtained indicator by 5 - 12 m. For example, the depth of the well is 10 m. A pipeline 20 m long is used for drainage The minimum head of the pump must be 10+20/10+10=22 m.
A good submersible well pump must meet all the necessary requirements.
Without determining the main parameters, it will not work to select a submersible pump.
Additional parameters for pump selection
To determine which better pump, it is also recommended to rely on additional parameters, which include:
- water quality. If the water contains a large amount of impurities, then it is more advisable to purchase a device equipped with additional filters or choppers;
- ways to start the equipment. If the well is located near the house, then the pump can be turned on by hand. If the well is located at a considerable distance from the buildings, then it is better to purchase a submersible pump for the well with automation, that is, the device will work depending on the water flow;
- cost of equipment. It is not recommended to purchase cheap devices, as in the case of submersible pumps, the famous saying "the miser pays twice" applies.
Rules for installing a submersible pump
Installing a submersible pump in a well does not cause problems even for an inexperienced user. Each device comes with detailed instructions installation and use of equipment.
The equipment is installed according to the following scheme:
- at the first stage, it is necessary to purchase all the components: a pump through which water will rise, a cable for fastening, an additional electrical cable, a check valve if it is not included in the pump kit;
- before installation, it is necessary to assemble the structure into a single whole. Work begins with the installation of a check valve that prevents the fluid from flowing back;
When installing a non-return valve, pay attention to the flow of water. It is usually indicated by an arrow on the hardware itself.
- Next, a pipe adapter is installed. All connections must be sealed with fum tape;
- at the next stage, a pipe is connected, designed to raise the water of their well;
- every 80 - 100 cm, a power cable is fixed to the pipe. This can be done using insulating tape or specialized clamps;
The cable cannot be attached to the pipe in a stretch. It should be slightly loosened.
- a steel cable is attached to support the pump in the well;
- the pump is lowered into the well to a previously determined level;
- the power supply is connected;
- a cap is installed on the upper part of the well to prevent its contamination.
You can learn more about the process of installing a borehole pump by watching the video.
The choice and installation of a borehole pump should be treated with the utmost attention. Incorrect selection of equipment, as well as incorrect installation, will lead to the inoperability of the entire water supply system.
