How does a surface water pump work. Surface pump installation technology: connection to water supply and irrigation systems

  • Available options for cleaning sewer pipes
  • Sewer line clogs are fairly common. It is necessary to correct the current situation as soon as possible, since it is impossible to use water in the house and apartment without sewerage.

    Blockages in pipes can occur for several reasons: Foreign body in the sewer! link down! (plug of debris, hair, and so on), narrowing of the pipe lumen!link down! to critical dimensions due to the accumulation of dirt and grease on the walls, improper installation! link down! , which led to the fact that the water stagnates in the pipe, and does not go away by gravity.

    Foreign body in the sewer system

    A blockage in the pipes in the form of a plug, consisting of sand, wool, hair, debris and other waste that does not belong in the sewer system, may occur if the rules for its operation are violated, as some believe that everything that passes through the drain can be dumped into the sewer pipe.

    If a blockage forms in the pipe immediately below the plumbing device, then only it will be out of service, and if the central riser is clogged, then all plumbing will be cut off.

    Large, non-dissolving debris can get stuck in the pipe and gradually accumulate smaller particles, grease and hair residue. All this can turn into a huge traffic jam, which can be quite difficult to remove.

    Narrowing of the tube lumen

    If you have a clogged pipe, then the likely cause may be the growth of rust and fatty deposits, which will lead to a decrease in the clearance in the sewer pipe.

    Very often this happens with pipes made of steel or cast iron. The water supplied through the water supply system has a certain chemical composition, which contains various salts, biological particles and chlorine residues after cleaning. The sewer system also receives used water containing detergents, traces of shampoo, shower gel and other contaminants. All this chemical cocktail reacts with the pipe material, the oxidation process begins, and rust appears. The corrosion process is quite long, it does not stop in a humid environment, so gradually the inside of the pipe is completely covered with rust.

    Sewer pipes made of plastic are not subject to corrosion. However, if the joints are poorly finished and/or there is a plastic burr, gap, protrusion, or other irregularity on the inside of the pipe, blockage of the pipe due to build-up of dirt may occur.

    Sticky fat will settle on the rough surface, which is not washed off with water. Remains of food after washing dishes and hair stick to the fat, which is why growths grow exponentially on the walls on the inside of the pipe until it finally clogs.

    Incorrect installation of the sewer system

    When laying the sewer, it is necessary to observe a slope of approximately 3%, due to which the drains will be discharged by gravity under the action of gravity. With such a slope, the water will be in good contact with the walls of the pipes and carry away all the polluting particles with it.

    If the slope is insufficient, then the drains may begin to stagnate, due to which the dirt from the walls will not be washed off, but continue to accumulate until a blockage forms. However, if the slope is too large, the water will fly through the pipe too quickly, because of which it will not have time to capture the remnants of household waste, which will eventually remain on the walls.

    Another rule for laying sewer pipes is to reduce the number of turns and reduce the degree of their angles (completely eliminate corners of 90 degrees). The more points of change of direction, the greater the risk of clogging.

    Plumbing cable

    This option is universal. The cable is made from a metal spring. Since the cable is long, it may be difficult to hold and turn it, so manufacturers pay special attention to equipment handles. Nozzles are fixed on the working part of the cable, thanks to which any parts of mud plugs can be destroyed.

    When choosing a cable, you need to pay attention to:

    • Diameter - is selected depending on the diameter of the sewer pipes.
    • Length - depending on the models, it varies from 2-3 to 45-60 meters. You should decide on the purposes of use and choose the most optimal option.
    • View - there are several types of models that are selected taking into account the characteristics of the sewer system.
    • Durability - it is worth paying special attention to the quality of the equipment. Savings are inappropriate here, as a good tool will last for several decades.
    • Material - it is worth giving preference to thick galvanized steel (especially if you plan to take a spring model).
    • The shape of the handle - it should fit snugly into the palm, since when using the equipment, efforts must be made to turn the tool in the pipe. For long ropes, a curved shaft is a suitable shape. It is optimal that the handle slides over the tool and, if necessary, is fixed in a convenient place.

    In addition to conventional cables, there are also electric ones that make it easier to remove blockages in the sewer pipe.

    A clear sign of blockage removal is the appearance of a swirl of water as it drains into the drain. If it appeared, then the pipe wall became smooth and clean. If it still does not appear, then you should repeat the cleaning procedure with a cable, and then pour boiling water, special chemicals, soda or citric acid into the pipe.

    If the cable is stuck in the pipe, then you can not make sudden movements - you need to slowly “loosen” it from side to side.

    Vantuz and its analogues

    The blockage in the sewer pipe can be removed with a plunger. Its advantages include versatility (suitable for any plumbing fixtures), safety (it will not get stuck in the pipe), practicality (easy to wash, use and dry), compactness, low cost.

    The principle of operation of the equipment is based on creating the effect of water hammer, which occurs during the translational movements of the device, which allows you to move the blockage, destroy it and move it further along the pipe. For the bath / sink and toilet, it is worth purchasing separate plungers to comply with hygiene standards.

    If there is no plunger, then a 1.5-2 liter plastic bottle can be used as a handy tool to remove small blockages. You need to cut off the bottom of the bottle and use it in the same way as a plunger, pumping water up and down.

    Soda and special chemicals

    Cleaning the sewer with the help of chemistry has one serious drawback - the inability to use it with a tight blockage of pipes. If the sewer system is clogged so that the water does not escape, then the product will not be able to get to the blockage.

    This option is effective for simple blockages that are located near the drain, and water, at least quite a bit, passes through the pipe.

    When choosing a cleaning agent, it is necessary to pay attention to the intended purpose and composition. Acid-based preparations are more suitable for use in the kitchen (they break down fats better). For the bath and toilet, alkaline products are more suitable (for splitting soap residues, dissolving hair and wool).

    The release form is also significant. Granular and powder formulations are considered more aggressive, and care must be taken when using them. Gel and liquid products are safer for plastic pipes. However, you still should not leave them all night, since an increase in the duration of the action cannot guarantee an improvement in the result, but it can damage the sewer system.

    Since chemistry is a dangerous method of dealing with blockages, as aggressive substances will later enter the environment. They can also cause an allergic reaction.

    A more eco-friendly option is a combination of baking soda and vinegar or salt:

    • Half a pack of soda is poured into the drain, poured with a glass of white vinegar and the hole is plugged with a rag.
    • A violent chemical reaction begins, it is necessary to wait for its completion.
    • When the composition stops foaming and hissing, you need to get the rag and spill the pipes with hot water.

    When installing equipment for wells, pumps of various types are used. Submersible pumps are most commonly used, but there are a number of situations where surface pumps are the most preferred. Their installation differs from the installation of a conventional submersible pump, but they do not need to be immersed in water, which means that the body is not subjected to such negative influences. Maintenance of such equipment is much easier and faster, if necessary, it is easy to check and adjust the pump.

    The surface pump, which is used for wells and wells, can be conditionally divided into several varieties. There are centrifugal and vortex, which are used most often. The first ones are designed to raise water from wells and shallow wells from 6 m to 9 m. Vortex ones are used for uninterrupted water supply with increasing pressure. Centrifugal ones are less expensive, they are easier to install. They cannot be used for deep wells. If it is planned to install an artesian well, then the equipment must be purchased special, since the depth is large, and not every unit will cope with such work.

    Pros and cons of surface pumps

    If a shallow well is drilled at the site, then a surface pump is suitable for it. Such equipment has numerous advantages in comparison with deep-well pumps. Among the undeniable advantages should be noted:

    1. The dimensions of the equipment are small, such a unit will not take up much space. There is no need to build a large and heavy foundation, and the size of the caisson can be small.
    2. Surface pumps are cheaper, for installation there is no need to use special equipment or tools. Control automatic blocks are purchased ready-made, their cost is not too high.
    3. The service life, according to the instructions of the manufacturers, is more than 5 years, but the equipment pays off already in 2 years, which greatly distinguishes it from submersible pumps that are used in a more aggressive environment.
    4. Installation of the device is simple, just connect the pipes and cables, and then check the operation. Together with the surface equipment, an accumulator tank is used, it contains a supply of water.
    5. The pressure, flow rate and other characteristics are excellent, the equipment provides uninterrupted water supply under any conditions.
    6. Electricity consumption is minimal, such equipment can be called economical.
    7. You can use a surface pump for a well or a shallow well, and this is beneficial for a summer cottage. The water column can have a minimum height of only 70-80 cm, for other models such working conditions are unacceptable.
    8. During operation of the equipment, there is no contact between the power cable and water, which is so important for ensuring safety.
    9. If the mirror is lowered during water intake, air pumping starts, then the automation stops the device. No damage will be caused to the equipment if the pump runs without water for some time.
    10. The repair is simple, there is no need to lift it to the surface, parts are easily replaced.

    There are also disadvantages of installing equipment on the surface:

    1. The well may only have a shallow depth.
    2. There is a need to install special filtering equipment, otherwise the pump will fail.
    3. Before turning on the pump, it must be filled with water.
    4. During operation, there is a lot of noise, which can interfere with those living in the house.
    5. The equipment can only be used in an insulated building; the caisson must be thermally insulated.

    How to choose a surface pump for home?

    In order for the pumping unit to work correctly and for a long time, it is necessary to approach the choice of equipment responsibly.

    Usually, surface pumps are used for a house with shallow wells and wells, but their operation is extremely simple, it is constantly supported by automation, which makes maintenance easier.

    The choice of the pump is based on what exactly the water will be used for. For example, the water consumption for a garden or vegetable garden, a greenhouse will be one, and for a house's water supply it will be completely different.

    When choosing, you must be guided by the following data:

    1. If a family of 3-4 people permanently lives in the house, it is best to use pumps whose productivity is approximately 3 cubic meters of water per hour. This is quite enough to supply the house, to provide all the needs of the family in water. If water supply to the greenhouse and garden is required, then the consumption will almost double.
    2. For an apartment building or townhouse, it is necessary to use surface pumps with a capacity of 5 cubic meters, but based on 2 families. For 4 families, equipment is used, the productivity of which is already from 6-7 cubic meters.

    Installation of a surface pump

    The installation of a surface pump is not complicated, it consists in the fact that a place for installation is selected on the surface, after which all pipes and communications are connected. It is not at all necessary to call expensive teams to install the device. But you need to have experience with plumbing equipment and pumps, as you will need to configure the device.

    Installation of surface equipment is carried out as follows:

    1. First you need to choose a place to install the equipment, it is best to do this in the caisson of the well or in a specially delivered structure that is mounted near the wells. Thermal insulation of the caisson or house is mandatory.
    2. It is necessary to mount the surface pump on the foundation. First, the concrete base is poured, and special metal fastening studs will be mounted into it. This helps to neutralize the load during motor vibration, the pump life will be significantly increased. It is important to protect the equipment from such loads, as they not only make the mechanism unusable, but also contribute to damage to other automatic equipment.
    3. Automatic control systems are mandatory, since it is with their help that the operation and control of the pump will be carried out. Such systems are selected individually, today there is a wide variety of them on the market. Blocks are best taken ready-made, they are fully balanced. You can also assemble such a block with your own hands, but if there is no experience in this, then it is better not to risk it. The control unit includes sensors and relays that control the productivity of the well, the level of the surface water film, and so on. If suddenly the water supply stops, then such relays stop the operation of the pump, give a special signal.
    4. Installation further involves connecting the nozzle of the device to a special supply water pipe, which is lowered into the wellbore or well. A non-return valve must be installed on the pipeline. It is he who will prevent the overflow and discharge of water when the pump is turned off.
    5. Then a special hydraulic accumulator is installed, i.e., an expansion tank. Before connecting it, you must immediately check the pressure that is observed in the chamber. It must fully comply with that declared by the manufacturer for operating conditions. If the pressure of the air chamber does not match the required one, then it is necessary to adjust it.
    6. After that, you need to connect the electrical cables for the pump. It is important to immediately provide a dedicated line for the supply of electricity, many experts advise focusing on a three-phase system.

    How does the equipment function?

    The pump is filled with water from a well or well (this is mandatory), after which it turns on. It is necessary to fill the expansion tank with water to the level that is set, then the automatic system will stop the pump itself.

    When the water in the tank runs out, that is, it is completely used up for the needs of the house or garden, the automatic unit will turn on the pump. You can set a trial mode to see exactly how the surface pump behaves, if there are any problems.

    If a well or a well is used for a summer cottage, the depth of which is relatively small, then it is the surface pump that will be the best way out of the situation. Its cost is acceptable, and installation is quite simple, since the device is placed on the surface. Caring for the device does not require special actions, all the work is done by automation.

    Surface pumps are characterized by small size, easy maintenance, relatively low cost and economical power consumption. Installing a surface pump on your own is much easier than installing a deep one. However, success is guaranteed only if the manufacturer's instructions and the recommendations of experts are strictly followed.

    On sale there are two types of surface electric pumps: vortex and centrifugal.

    • Whirlpools provide an uninterrupted supply of water with increasing pressure, they are used for watering gardens and quickly pumping out the contents of wells and barrels. Vortex-type devices are sensitive to debris - they should not be used in polluted water bodies.
    • Centrifugal pumps are highly efficient and suitable for permanent plumbing. Self-priming models are not afraid of air congestion and the formation of air bubbles in the system.

    Electrical appliances for pumping water can also be divided into stationary and portable. Stationary models are installed in water supply systems, while mobile ones are used for watering and draining flooded cellars and basements.

    Connecting a surface pump to a well or well

    Important! Installation of a surface pump is possible only in wells and wells with a depth of no more than 8-9 meters. Deeper shafts require a submersible tool.

    The easiest way is to connect mobile equipment to a country well, which is used exclusively for irrigation. It is more difficult to connect a stationary pumping station to an autonomous water supply system. This will be discussed further.

    In addition to the electric pump, to connect it to the water supply system at home, you must have:

    • inlet and outlet pipes or rigid hoses with a cross section of 32 or 25 mm, the length of the pipe is calculated so that the lower end is immersed in water by at least 30 cm, while the total length should not exceed the size indicated in the passport for the device;
    • connecting fittings;
    • storage tank with a volume of 30-60 liters;
    • flexible hoses for connecting the tank to the pump;
    • five-pin adapter for the second output;
    • pressure switch;
    • manometer.

    In order to reduce the number of starts, a self-priming surface pump is recommended to be connected to a storage tank and an automatic activation control system. The storage tank also acts as a hydraulic accumulator that regulates the pressure in the pressure system and protects it from water hammer.

    Many manufacturers produce ready-made pumping stations, which include all the necessary equipment. If a separate device was purchased, the missing components will have to be purchased separately.

    Surface pumps are always mounted on land - in no case should water enter the device case. Ideally, the electric pump should be mounted as close as possible to the well or well. The room should be dry, relatively warm (with a positive temperature) and well ventilated. It is possible to install a pumping station in the basement, but in this case you will have to put up with constant noise.

    To place the device near the well, small buildings are built or the equipment is placed in underground caissons - concrete, plastic or metal insulated structures with ventilation, equipped around the well casing. Caissons are built below the freezing level of the soil. In this case, water pipes to the house are laid in a trench, also dug in non-freezing layers of soil.

    Instructions for connecting to autonomous water supply

    This step-by-step description of how to properly install a surface pump in an autonomous water supply system is relevant for all types of pumping equipment. Failure to do so may result in damage and accidents.

    1. Before connecting the surface pump to the water supply system, it is fixed on a fixed base with bolts. To neutralize vibrations, it is recommended to use a rubber mat or special nozzles on the legs as a gasket.
    2. A hose is connected to the outlet, to the other side of which a check valve and a coarse filter are attached, sealing the connections with a special tape or flax.
    3. Outgoing pipes leading to the water supply are connected to the second outlet, located in the upper part of the housing.
    4. The non-return valve is immersed in water, providing a slight slope in the pipe or hose line from the valve to the pump.
    5. At the next stage, the system is filled with water through the outlet holes or filler plug. It is important to bleed all the air out of the system!
    6. Next, connect the pressure part with wiring around the house. At this stage, the filler hole is closed and the pressure in the accumulator (tank) is checked. If the pressure does not correspond to that specified in the instructions, it should be increased (topped up with a pump) or lowered (lowered).
    7. Having clearly completed all the steps, the electrical equipment is plugged into the outlet and started. The switched on pump must start working and fill the system and the accumulator with water.
    8. Turning off the engine indicates that the pressure in the system has reached a maximum (from 1.5 to 3 atmospheres).
    9. Now you can open the tap and make sure that the installation is working.
    10. If, when the valve is open, the pressure does not correspond to the parameters prescribed in the instructions, it is necessary to adjust the operation of the relay.

    Installation features for other water supply systems

    Even after reading the recommendations on how to properly install a surface self-priming pump in a well or well, it may be difficult to connect equipment to other sources. These tips will come in handy for those who are going to automate the supply of water from a column or storage barrel.

    It is not too late to think about how to connect a surface pump to a column, even after installing a manual pump. It is recommended not to dismantle the manual control, but to supplement it with automation.

    For both devices to work, you need to cut under the column check valve, install a tee with a check valve and connect the electric pump through a rigid pipe. It is better to replace the check valve on the column or install another one on the tee to prevent air from being sucked from the side of the column. A ball valve is inserted between the hand pump and the nozzle.

    The principle of operation of the combined column is simple: first, the column is raised above the ball valve with a hand pump, then it is closed and the electric pump is started. It is important that there is always water in the “glass” of the column; if necessary, it must be added.

    Irrigation barrels help out in summer cottages and suburban areas, and the use of a pump greatly simplifies the hard work of a gardener. The electric pump not only automatically supplies water, but also creates the necessary pressure. It is easy to find low-cost simplified barrel equipment and advanced automatic garden models that work with micro-drip irrigation systems.

    Before connecting the surface pump to the barrel, it is necessary to attach hoses for water intake and irrigation to the device. Rubber hoses are not suitable for this purpose - they will simply shrink from the pressure of the water and will not be able to perform their task. The device is installed on the ground, as close as possible to the tank. Only hoses are lowered into the water - the body of the device must remain out of reach of splashes. After completion, the pump is stored in a dry place.

    Especially for summer residents, they came up with compact barrel models - they are installed on the edge of a container of water. These convenient devices are equipped with filters and pressure regulators. There are almost always hoses in the kit.

    Detailed video instruction for installing a surface pump

    It is not difficult to understand the operation of irrigation devices, but you can proceed with the independent installation of a surface pump for water supply at home only after carefully studying the manufacturer's instructions. If it contains a lot of incomprehensible information, it’s not worth the risk, it’s better to entrust this complex process to professionals.

    The well itself is preferred by most of the owners of agricultural areas as a source of water for equipment and independent organization. What type of pump is most suitable in this case and according to what aspects to make a choice - this is the only one of the main problems that we have to solve! We will select an option and find out what is the best surface pump for a well.

    Initially, we need to understand the specifics of using this type of equipment, and we also need to point out certain useful features of such products.

    How to connect a surface pump to a well - characteristics and various models

    Water is pumped by suction through a hose absorbed into the water, with further supply to the place of water intake. The operation of these devices is different from each other. Common features: versatility in use.

    Firstly, it greatly simplifies the visual supervision of the functioning, periodic services (in some models it is taken into account) and, if necessary, maintenance. Secondly, if the product is determined at a place where year-round is not required (for example, a summer cottage), in this case it is easy to dismantle and move it into the house, up to the next year. Nor will we offer any type of shallow pump or distribute certain models. Each person decides for himself, in accordance with the criteria for the operation of the product. However, in order for the selection to be correct, it is necessary to understand something about such devices. But still, let's clarify - for a horizontal pump well, only vertical ones are used, since the direction of water movement is up.

    Types of pumps. Well construction with a surface pump

    Centrifugal surface pump

    Surface pumps are constantly installed on land - in no case should water get into the block housing of the device. Ideally, the pump must be installed as close as possible to the well or to. The accommodation must be dry, relatively hot (with a positive temperature) and well ventilated.

    Now it is allowed to open the tap and make sure that the structure is working. When, with the valve open, the pressure does not meet the characteristics written in the instructions, the operation of the relay should be adjusted.

    Installation features for other water supply structures

    Even after reading the advice on how to correctly identify a shallow self-priming pump in a well or, difficulties may arise when turning on equipment to other keys. These recommendations will be needed for someone who plans to automate the supply of water from a column or a storage barrel.

    Connecting an electric pump to a column, it is worth thinking about how to connect a shallow pump to a column, it is not too late, including later the design of a manual pump. It is recommended not to disassemble the manual control, but to fill it with automation. In order for both devices to function, it is necessary to cut under the rear valve of the dispenser, identify the part with the check valve and connect the pump through an iron pipe. It is more correct to change the opposite valve on the column or install one on the tee to prevent air from being sucked from the edge of the column. A spherical rectifier is cut between the hand pump and the nozzle.


    The rule of operation of the combined column is elementary: first, a column is raised with a hand pump more than a spherical valve, then it is blocked and the pump is started. It is essential that there is always water in the “glass” of the column; if necessary, it must be added by all means.

    Surface pumps for wells allow you to pump water from a shallow depth, which is important for owners of country houses and summer cottages.

    We will talk about the main characteristics and features of these devices, and also show how a surface pump is installed in a well.

    Surface pump

    Device and purpose

    Surface pumps work on the principle of water suction by creating a vacuum at the end of the suction hose, lowered by the other end into the water. Thus, a pressure difference arises at different ends of the hose, and with full vacuum at the suction, it will be the value of atmospheric pressure, that is, about 760 mm of mercury.

    If we replace the mercury column with a water column, then the height of such a column will be 10.3 meters, which means that with a full vacuum on the suction side, the water can rise no more than 10.3 meters.

    Taking into account the losses due to friction of water against the pipe walls and incomplete vacuum in the system, the maximum water lifting height of such a pump will be no more than 9 meters, and if we take into account the horizontal part of the suction pipe, it turns out that the actual working height will be 7 - 8 meters.

    Important!
    When calculating the parameters, the distance from the well of the surface pump should be taken into account.
    The following formula would be appropriate here:
    Y = 4(8-X), where Y is the length of the horizontal part of the pipe, X is the suction head.
    That is, four meters of the horizontal part is equivalent to one meter of elevation.

    Important!
    From the above calculation, we can conclude that the surface pump is designed to lift water to a height of up to 8 meters.
    This allows you to use this device for water intake from open reservoirs, shallow sand wells and wells.

    By design, external pumps are divided into three main types:

    1. Vortex. The most compact and inexpensive devices capable of creating a sufficiently high pressure in the system, however, they have a low efficiency - no more than 45%. They are mainly used for irrigation and pumping water from flooded premises, but low efficiency and low reliability do not allow us to recommend this type of equipment as a permanent unit for an autonomous water supply system;
    2. Centrifugal. More expensive and reliable devices that create, although less than vortex ones, but quite sufficient pressure to ensure the operation of the water supply. They have a high efficiency factor - up to 92% - with sufficient reliability for continuous use, which allows the use of this type of equipment in the operation of pumping stations for water supply;
    3. Ejector. They have two water circulation circuits: in the first circuit, the liquid is supplied to the ejector nozzle, where, due to the Bernoulli effect, a pressure difference is created and water is sucked in from the external environment - the second circuit. This solution allows you to lower the ejector to a depth and solve the issue of limiting the suction height, but now more efficient submersible units are used for these purposes, the price / quality ratio of which is higher.

    As you can see, centrifugal pump designs turned out to be the most practical, so we will dwell on them in more detail.

    The centrifugal unit is arranged quite simply:

    • Two disks are rigidly fixed on the gearbox drive shaft, in the center of one of which there is a hole;
    • The hole communicates with the interdisk space, where inclined plates are soldered, creating channels from the center of the space to its edges, which are connected to a collector tank (diffuser) that communicates with the supply hose;
    • A suction hose is connected to the hole in the center of the disc;
    • If you fill the suction hose and the inter-disc space with liquid and set the gearbox drive in motion, then the blades inclined in the opposite direction to rotation will begin to push water from the center to the edges of the space between the disks due to centrifugal force;
    • As a result, a vacuum will be created in the area of ​​​​the wheel center and the suction hole, and an area of ​​​​high pressure will be created in the area of ​​\u200b\u200bthe edges and the diffuser communicating with the discharge hose;
    • Under these conditions, the system will tend to balance, and water will be pushed out by pressure from the storage tank at the edge of the wheel into the discharge hose, while a vacuum will appear in the center of the wheel, and liquid from the suction hose will rush there under the action of atmospheric pressure.

    As a result, continuous circulation is created and water is pumped from one point to another, which was what was required to be achieved. However, to work in the autonomous water supply system of the house from the well, the surface unit is not used independently, but the so-called pumping station is assembled, which is discussed in more detail in the next paragraph.

    Pumping station

    For normal operation of the surface pump as part of the water supply system of a residential building, it is connected to a storage tank and an automatic switching control system. This is necessary in order to reduce the number of unit starts per unit of time.

    The fact is that when the power is turned on, peak current values ​​\u200b\u200bappear on the motor winding, which are called starting currents. These currents cause a destructive effect on the device, therefore, from the point of view of the operating life of the electric motor, it is much better for it to work with the least number of start-up cycles.

    On the other hand, the constant operation of the pump is not necessary and economically disadvantageous, since it consumes a considerable amount of energy and devastates the well. Obviously, it is necessary to create a certain supply of water and pressure in the system, which will cover the constant switching on and off of plumbing fixtures and taps, and only when this pressure drops below certain values, the pump will turn on and restore the supply.

    Accordingly, when a certain peak pressure in the storage tank is reached, the pump will automatically turn off.

    So we approached the device of the pumping station, and its main parts are:


    Important!
    With a sufficient volume of the storage receiver, the system will turn on the pump quite rarely, which will significantly extend its service life, as well as extend the service life of motor starters and terminal blocks.
    In addition, peak pressure values ​​​​and characteristic water hammer will not occur in the water supply system, which will secure shutoff valves and pipe connections.

    Connecting a pumping station to a well

    If you plan to connect a surface pump to the well with your own hands, our step-by-step instructions will help you:

    1. The pumping station (or a separate pump) is installed on a solid fixed base and the legs are fixed with bolts or anchors. It is recommended to lay a rubber mat under the installation to reduce the vibration activity of the device;

    1. The outlet (supply) of the pump is connected to the inch outlet of the five-outlet fitting with a hose or directly;

    1. The accumulator tank is also connected to the inch outlet of the fitting using a soft hose or directly;
