The water pumping station is not working. Why the water station does not gain pressure: we analyze the reasons and troubleshooting methods. The pumping station does not gain pressure

Any malfunction of the water supply system at home is the result of an error by the organization or individual involved in its implementation. In this case, the homeowner has a good chance to learn from his mistakes by repairing the electric pump with his own hands and, with a “successful” set of circumstances, improve his health by carrying water manually for some time from the nearest water source.

Rice. 1 Well pump assembled

This sequence of actions applies to all types pumping equipment regardless of the location and method of installation. It should be noted that the pump power supply system, apart from the wires switched by switches, does not have complex circuits, so if water submersible pump does not pump water, but starts up and hums; problems with the supply of the necessary supply voltage can be ruled out in the vast majority of cases.

If the water doesn't pump drain pump or a well model, it may not start if the built-in or external condenser is faulty and will require repair and replacement.

First of all, repair of electric pumps should begin by turning off the supply voltage, removing it from the water intake source and disconnecting the outlet hose.

When reconnected, the reasons why the pump does not work can be divided into several areas according to the location of the manifestation - we will consider them below.

Rice. 2 Water supply scheme for a private house

Malfunctions of pump protection systems

Typically, a properly assembled water supply system and high-quality pumps have devices that prevent them from operating in idle speed.

In the event of a malfunction of such protective devices: borehole dry running relay and float switches for drains, well or sewage pump, devices can operate in the absence of water.

Sometimes the float switch of wells or drainage pumps due to improper installation, it does not fall along with a drop in the water level (it falls on a hillock or clings to a protruding object) - this leads to the electric pump operating in idle mode and its further failure.

Vibration pumps, which usually do not have external protective devices connected to the system, operating for a long time without water after its level drops, can fail in the absence of built-in thermal protection.

Depressurization or breakage of the water main

The malfunction will help to identify the removal of the deep pump from the water intake source and connection to the supply voltage on the surface. If a pump lowered into water for testing pumps water from the right pressure, then you should look for a leak at the place where the hose is connected to the outlet pipe or in pipes that are laid underground during regular water supply to the house (in a house, a leak can be easily noticed by the presence of water on the floor in the room with pumping equipment).

Mismatch between pump parameters and water intake source

During the dry season or with a sharp increase in water consumption, a situation may occur when the well or well does not have time to fill (the flow rate of the source is too small for normal operation pumping equipment). In this case, the electric pump will operate in dry running mode for some time in the absence of a similar relay or float switch in the system.

Clogged water intake system

Very common reason lack of water when the pump is running. Similar malfunctions can occur during the installation of pumping equipment: dirt and foreign objects can penetrate into the pipes. During operation, the grids become clogged and replaceable cartridges filters.

The filters and impeller of the impeller of submersible devices need regular cleaning during operation - if this does not happen, over time they become clogged and the operating pump hums, but does not pump water or does so with low pressure.

A situation often occurs when the pump actuator stops completely when clogged - the impeller does not rotate, and the vibration pump piston does not move. A clogged well or drainage pump removed from a water intake tank does not pump water when turned on superficially - do-it-yourself repairs will require disassembling and further cleaning of the device mechanism.

The pump has failed

The biggest problem that can happen to an electric pump is the burnout of the winding, and the device usually cannot be repaired (rewinding the winding with your own hands is difficult, and in a workshop the cost of work and materials will not be comparable to the price of the electric pump).

With this malfunction, the electric pump will hum, but will not be able to pump water.

Sometimes the impeller of borehole and well pumps may break, the system of check valves may fail (they will not allow water to pass through) and the piston ring of vibration models may fail.

Due to constant vibrations during operation, vibration pumps are subject to loosening and unwinding of the mounting mechanism of the composite body, the fixing nuts of the check valve and the piston. These factors can lead to the loss of functionality of a working electric pump, which will hum but not pump water.

Violation of the operating rules for submersible pumps, errors in the installation of the water supply system, a sharp increase in water intake and a decrease in the flow rate of a well or borehole can lead to the hum of a working electric pump, in which water will not flow to the consumer. In most cases, you can repair electric pumps yourself if you remove the device to the surface for precise definition problem area.

Pumping stations for water supply to a home or cottage have gained wide popularity among people living in the private sector. On the Internet you can find different reviews about their work, advantages, disadvantages. After all, automatic water supply to the house for household needs is very convenient.

But over time, unfortunately, various malfunctions sometimes begin to appear: the pump does not work or does not gain pressure, does not turn off for a long time or, conversely, does not turn on. The reasons for this may be different and it is necessary repair of pumping stations, this is what we will talk about in this article.

We will analyze the main malfunctions in the operation of the water supply, what could be their causes, and develop the main methods for troubleshooting.

Main malfunctions during the operation of pumping stations

Based on experience in operating pumping stations, the most common malfunctions in the operation of this type of equipment are:

1. What to do if the pump does not work

Possible reason: lack of voltage in the electrical network or the shaft is blocked.

First, check the voltage; if this is not the reason, try turning the pump shaft yourself, first disconnecting the pump from the power supply.

2. The pumping station does not pump water, although the pump itself is working.

The main reason in in this case maybe education air lock in the suction section of the pipe or in the pump itself.

Unscrew the plug on the pump filler hole. Try to force the air out of the pump by rocking it and the suction pipe. Check the pipe and fittings for leaks. Then refill the pump with water and turn it on.

3. The pump turns off due to engine overheating

One of the reasons could be:

- mismatch of mains voltage

— the pump impeller is blocked

— the pumping station was under the Sun for a long time or was driven through the pump hot water

— the pump worked “dry” without water

Turn off the pump, check the impeller, eliminate the cause, wait until the engine cools down.

Pumping station repair

There could be three reasons:

- if the membrane in the hydraulic tank is torn, replace it with a new one

- if not required pressure in, then pump up to 1.5 atmospheres

- may be faulty, replace it with a new one

5. The pumping station does not gain or maintain pressure

Adjust the pressure in the relay, it may not be enough.
It is also possible that air can get into the pipe.

6. The water supply pumping station does not turn off

Incorrect parameter settings.
It is necessary to set a lower pressure.

Watch the video

So, we have analyzed the main malfunctions in the operation of pumping stations, identified the main causes of malfunctions, and learned methods for eliminating them. This work can be done with your own hands, but it is better to contact specialized organization for repair of pumping equipment (stations).

Sometimes happy owners of a well and an autonomous water supply country house Face a problem when water stops flowing from the faucet in the house. There can be many reasons why the pump does not pump water from the source. To get rid of this problem, you need to find and eliminate the cause. In our article we will describe the most common reasons why a pump may not pump water out of a hydraulic structure. In addition, we will give recommendations on how to eliminate them.

For serviceable and uninterrupted operation pumping equipment requires two important components - water and electricity. If you identify the element that does not allow the unit to work, it will be easier to find the cause.

In order for a well or other hydraulic structure to supply water uninterruptedly, 4 conditions must be met:

• The source must have water that can be pumped.
• Correct power supply to pumping equipment (frequency and voltage must correspond to the parameters for which the unit is designed).
• The pump must be in good working order, that is, its power and performance must be within normal limits.
• All taps, filters, valves and pipelines must be in working order.

Since the water supply system can be used not only for the home, but also for watering the garden, the problem must be looked for in three directions:

• in a hydraulic structure;
• inside the house;
• in the ground.

But it is necessary to act by elimination. First, disconnect the supply hose in the caisson. If the liquid flows, then the problem lies in the house or on main pipeline in the trench. If the water does not flow, then the problem should be looked for below the ground level in the well or equipment.

If the pump unit hums, but does not pump liquid, then the problem may be the following:

1. An error was made during the installation process, at the stage of selecting components or during operation.
2. Sometimes this happens due to power surges or a significant decrease in the amount of water in the source.
3. A phase loss may occur during internal structure electric motor.

Advice: if a previously properly working unit does not pump water, then the reason should be sought in the lack of water or electricity. With new equipment that has not been used before, everything will be more complicated. Here the reason can lie anywhere.

Common reason

If your pumping equipment hums as if it is working, but does not pump water from the well, then the reasons may be related to mechanical damage or clogging of a hydraulic structure. First, try to remember what kind of water came from the tap the day before the breakdown.

If a cloudy liquid flowed from the tap or the pressure suddenly began to decrease during the standard operating mode of the pumping equipment, then the trouble most likely lies in the well itself. This happens if a hydraulic structure becomes silted or clogged. This phenomenon is usually called well sanding. And they can call it:

• small algae that live in water;
• solid impurities brought by the current;
• shedding of rock from the walls of the tunnel;
• sand lifted from the bottom of the well by pumping equipment.

All these components can clog the lumen of a hydraulic structure. As a result, first it will come out of the tap muddy water with sand, then with air, and then the flow will stop altogether. In this case, the dry-running protection in your pumping equipment may not work.

To fix the problem, you need to:

1. Remove the submersible pump from the well.
2. All water from the hydraulic structure is pumped out.
3. The interior space is disinfected.
4. The water is pumped out again. The time for repeated pumping depends on the disinfectant used.

After cleaning the well, the pump should start working. But even if this does not happen, you should not hang your nose, because cleaning the hydraulic structure will benefit the quality of the water and the durability of the source.

What to do next?

If cleaning the well does not help, then the following situations may be the cause of the malfunction:

• failure of mechanical parts of pumping equipment;
• breakdown in the power supply system;
• violation of the tightness and integrity of the main pipeline;
• malfunction of one or more pump control units.

But to understand exactly what the reason is, the submersible unit must be raised to the surface from the well. Then the pump is lowered into a container of sufficient size filled with water and started:

1. If the engine starts running when starting, it means there is no breakdown in the electrical system. Otherwise, such malfunctions may be suspected. But searching for and eliminating the causes of electrical system failure should be carried out by an experienced specialist.
2. It's worth watching the engine running. At the same time, try to visually assess the integrity of all pipelines and hoses. Sometimes the pump does not lift water well because the hoses are not sealed and the pressure in the system has dropped.
3. But the leak may not be immediately noticed, especially if the damage is very small. To make such places more noticeable, the outlet hole on the hose must be closed with your hand. Then the pressure in the pipeline will increase, and jets of gushing water will appear in places of depressurization.

Important: it is better not to seal a damaged hose, but to purchase and replace it with a new one. The thing is that due to strong pressure, the patches can come off.

If the unit is working but does not pump water

Let's assume that there are problems with electrical system and the integrity of the hoses was not detected, but the water pump still does not pump liquid from the well. To look for an answer to the question of why the device does not pump water remains only in the pumping equipment itself. To do this you can do the following:

1. First you need to check the filter device and check valve. They may be clogged and will need to be cleaned. In some cases, it may be necessary to replace these products or one of them with a new element due to complete wear of the old part.
2. The second unit to be checked in a BC (domestic centrifugal) pump is protection against “dry running”. The sensor could simply burn out, so the unit began to work in a well without water. This quickly leads to overheating of the electric motor and failure. It is better not to repair such equipment, but to replace it with a new product. This will make it more reliable and safer to operate the unit in the future.

Common faults

Most often, well owners are faced with a problem when the submersible pump previously worked properly and pumped water, but suddenly the water from the tap stopped flowing. We will list possible malfunctions that led to this situation, and also tell you what to do:

1. Significant decrease in water level in a hydraulic structure. In this case, the water flows normally at first, then flows weakly and the flow stops altogether. In this case, equipment with a thermal relay or float mechanism will automatically turn off. Dry running protection may also work. Typically this problem occurs in summer period during a drought, if mistakes were made when digging a well or borehole or their productivity was incorrectly determined. Solution:
   • always use protection against dry operation, this way you will maintain a working pump;
   • Drilling a well or well is best done in winter, when groundwater stand at the lowest level, then in the summer the level will not drop critically;
   • for drilling, contact only professionals;
   • Perhaps the well needs cleaning.

1. The productivity of the pumping unit is higher than the flow rate of the hydraulic structure. In other words, the source does not have time to fill with water, and the pump quickly pumps it out. In this situation, the same thing happens as in the case of dry work. The sensors will work and turn off the pump. This can happen if the pumping equipment is incorrectly selected, many water intake points are open and the garden is being watered at the same time. To fix the problem you need:
   • choose the right pump based on the productivity of the well and equipment;
   • when choosing, take into account peak hours of water consumption;
   • do not open all the taps in the house at the same time;
   • The motor power reserve should be small.

1. Weak pressure does not allow raising water from the source. This can also happen if you choose the wrong equipment. For example, if for a well 50 m deep you purchase a device with a maximum pressure of 30 m, then it simply will not be able to lift water to the surface. In this case, you will hear the sound of the unit operating until the thermal relay cuts off the power. To fix the problem you need to choose the right pump.

Advice: when selecting a unit based on pressure, it is worth taking into account the horizontal sections of the pipeline. At the same time, they are counted in a ratio of 5 to 1, that is, 5 horizontal meters are equal to 1 vertical meter.

1. Undervoltage. Many pumps are very sensitive to voltage deviations in the network. When it drops below 200V, the submersible unit may either not turn on at all, or it may start, but sharply reduce the pressure and then stop supplying water. To detect the problem you will need measuring instruments. To resolve this, you can do the following:
   • connect the pump to the generator;
   • use a voltage stabilizer or autotransformer.

1. Pipeline clogged, shut-off valves or filter device on pumping equipment. This is often observed during the first start-up or after maintenance, as a result of which debris, dust and dirt get into the pipes, clogging the listed parts. Sometimes this happens due to debris entering from the bottom of a hydraulic structure. To combat the problem you should:
   • Be careful when assembling new equipment or performing maintenance;
   • lift the pumping equipment to the surface and wash it; to do this, the unit must operate in a container of water with the check valve removed and without a pipeline.

1. Disconnected or damaged pipeline. In this case, the gurgling of water will be heard from the source. You need to check the connection and integrity of the hose.
2. Complete failure of pumping equipment. If you can hear the sound of a running motor, but you haven’t found any other reasons, then you can assume there is a problem with the mechanical parts of the pump. All that remains is to lift the unit to the surface and carry it to the service center.

When moving to country house or a summer house, you will certainly need to take care of the level of comfort. First of all, you need to create or establish a water supply system that will effectively perform its main functions. Creating such a system is expensive, because the initial investments are quite high when compared with connecting to public water supply networks. Savings will manifest themselves in the near future, since there will be no payment for water use.

Your own pumping station is not only savings cash, but also additional obligations imposed on the owner. Repair and periodic maintenance of the system will not take long, so the homeowner should be aware of how it is carried out DIY pump station repair.

Like the human body without a heart, the water supply system cannot function without a pumping station. Any autonomous system water supply must be connected to a well capable of supplying a certain area required quantity water.

People living in private houses extract water using pumps, since the depth of wells can sometimes reach several tens of meters. The pumping station is used to maintain constant pressure in plumbing system and pumping liquid from one place to another.

What does it consist of?

The average pumping station has three main components, namely:

• pumping device;
• hydraulic accumulator;
• automation block.

Now let's look at each element in more detail.

Pumping device

Water supply stations are most often equipped surface pumps, whose names indicate their location. They are installed in specially equipped xenon systems, or inside residential premises. Pumps are used with quite high power, since it is necessary for raising water from wells and transporting it to the house.

A small device is enough to service one home

Hydraulic accumulator

A hydraulic accumulator (also called a pressure accumulator) is metal device, the purpose of which is to maintain a certain level of pressure on a constant basis. The most popular is a model that is a small metal cylinder with an elastic membrane installed inside. During operation, the rubber membrane is deformed to a certain point. When work stops, it returns to its original position, displacing liquid from the cylinder.

Automation block

It is designed to promptly stop the operation of the device. It works like this:

• the pressure decreases to a certain point;
• the relay starts to operate;
• the pump comes into play and the accumulator begins to fill with water;
• upon achievement optimal pressure The device is suspended.

As you have already noticed, a pumping station is a combination of components and assemblies, the operation of which can also be done separately. In most cases everything the main components of the unit are installed on one housing, however, there are also models in which the pumping device is installed on a pressure accumulator. Device automatic control is also located on one body.

During the entire warranty period, there are practically no problems with the equipment during operation. But this does not mean that you will not have to troubleshoot problems. various nodes. Over a long period of operation, any part of the mechanism can break, so you need to be prepared for anything that happens. Let's look at the possible causes of failure and options for resolving these problems.

Causes of breakdowns

Even the most reliable mechanism not eternal, this also applies to the pumping station. There are quite a lot of breakdowns due to which work is disrupted or stopped altogether. Here are the most common ones:

• membrane tank is broken;
• pump is broken;
• there is no liquid in the system;
• the automatic unit is damaged;
• no electricity and others.

The simplicity of the design of household pumping stations allows you to carry out diagnostic and repair work yourself. Sometimes it is enough just to replace a non-working part. In some cases, it is necessary to resume sealing in the tank by sealing the crack, and sometimes even to determine the flow of electricity to the mechanism. Each specific case comes down to a single question - why is the pumping station not pumping water and how can the problem be solved? In unsuccessful attempts to identify optimal solution It makes sense to seek help from specialists.

Repair of a pumping station - the most common problems

We will analyze in detail all common problems in work, possible causes of their occurrence and options for quickly eliminating them. with my own hands, without the help of specialists.

There is no water in the system, although the pump is running

The water has stopped flowing, but the pump impeller is operating normally. If such a problem occurs with your station, then read the following recommendations.

1. Swipe thorough examination everyone connecting pipelines for the presence of breaks and cracks (even the most minor ones). Valve malfunctions are the main contender among all causes of malfunction. Check its condition for any external damage. For those who don't know where the check valve is located: between top part wells and pipe. Foreign objects caught in this valve can easily break it. It may also be that the spring that controls the operation of the valve has broken or failed. To solve the current problem, a replacement will be required. If found large quantity dirt in the valve, remove it and clean it. In the event of a breakdown, complete replacement valve
2. The pumping equipment has not been used for a long time - because of this, water may disappear in the pipeline (just in the place between the pump and the well). To fill the void in the pipeline, you need to use a special filling hole.
3. Seasonal decrease in water level in the well. To solve this problem, it will be enough to lower the lower part of the pump a little lower into the well. Be careful when doing this, as submerging the pump too deeply can cause contamination. To prevent contamination, there are special filters that need to be equipped with the pump. You can also make them yourself.
4. Power outages can also lead to poor water supply. If the pump rotates but there is no water flow, check the voltage electrical network. For this you will need a power supply tester. The fact is that the rotor in the system will work, but due to low voltage the rotation speed will drop and this is no longer enough to move liquid from the well to the house.
5. Pay attention to the condition of the pump impellers. Over the course of many years of operation, they can become very worn out. To solve this problem, you will need to remove the pump impeller while disassembling the pumping device. In almost all models, the impeller is hidden under the housing cover, secured with two bolts. Long service life will make itself felt, and unscrewing these bolts will become quite a difficult task for you. Thanks to the creators of WD-40. Having finally removed the housing cover and reached the impeller, carefully inspect it. If there is damage, it must be replaced, but there is one big “but”. The fact is that many manufacturers do not produce small parts separately, so you will most likely have to make a replacement. Alas, this is now the policy of manufacturers.

Important: The problem with low voltage is especially relevant for residents of rural areas. Therefore, before starting repair work You definitely need to inspect it first.

The pumping station operates jerkily

There are several possible reasons, one of which is a malfunction of the automation unit. Its main component is a pressure gauge (this is a special device that measures pressure). The pressure gauge needle will move sudden movements from wall to wall of the pressure gauge during such inadequate operation in jerks.

Damage to the membrane may well be the main cause of malfunction of station components. The operation of the membrane in a hydraulic accumulator was mentioned earlier.

The membrane can only be reached through a nipple installed in the rear side of the pump housing. Lightly press the nipple and you will feel a stream of air coming from it. Well, if instead of air you see a trickle of water, then the accumulator membrane needs to be replaced. To do this, you will need to disassemble the battery case.

Video - Replacing a pear in the hydrosphere

Another common reason bad work system - low pressure in the bulb. We are talking about a pressure drop in the area behind the membrane. The factory standard assumes a pressure of 1.8 at, but during operation the tightness of the pipelines and housing may be compromised, causing the pressure level to drop. The pressure level can be increased through the nipple installed in back side housings. If there are microcracks, this method will not help; a different approach is needed here - “ cold welding", thanks to which it is possible to repair the resulting cracks. If welding does not help or the cracks are too large, then the accumulator housing needs to be replaced.

Another, albeit quite rare, reason is that the automatic adjustment unit has broken down. In this case, only a complete replacement of the device will help.

Water supply is intermittent

The cause of intermittent water flow will most likely be air entering the pipeline. Air entry most often occurs in the section between the inlet and suction pipes of the device. Troubleshooting can be done only by one method - you need to ensure complete tightness of all pipelines, including connections. If possible, lower the suction pipe slightly lower than the ground level.

The unit works continuously without stopping

To the very probable reasons Such a nuisance can be attributed to an unregulated relay designed to fix the pressure level. The procedure for adjusting the pressure switch can be done by changing the position of two springs - small and large.

small spring

It is installed on the relay and is intended to equalize the pressure between minimum and maximum.

Big spring

This spring is installed on the relay to create limits for turning on or off the system.

During operation, the operation of the springs may be disrupted due to their premature stretching. As a result, the initially established indicators are lost. In addition, when long work There is a risk of wear on the moving parts of the pump, causing the pressure readings to drop.

TO possible reasons A malfunction in the operation of the adjusting relay can be attributed to a decrease in the size of the hole in the relay; it is also called “output”. The narrowing occurs due to deposits located in well water. Clean the relay and the problem will go away on its own.

The pump does not turn on

The pumping station is powered by electrical energy, the absence or fall of which will certainly cause the device to stop working. Using an electrical tester, check the voltage level.

If there are no power outages, you need to look for the cause of the malfunction elsewhere. In this case, this is a violation of the winding in electric motor. The presence of breakdowns in the winding is accompanied by the engine stopping and the appearance of a burning smell (the insulating materials). Only a complete replacement of the electric motor will help solve this problem.

The pump makes noise, but the shaft does not rotate

With pumps that long time lay without work, such a problem may happen. This is due to the fact that due to downtime, the moving parts jammed over time (for example, they became stuck or rusted). Try to start the blocked impeller yourself. If everything worked out and you managed to turn it on, great, but if not, disassemble the pump and solve the jamming problem.

The combustion of a capacitor can lead to similar “symptoms”. It is installed in the terminal box of the unit. To identify and eliminate this malfunction, you will need an electrical tester.

Most often, the capacitor burns out in those motors that are connected using a three-phase circuit.

A little about relay adjustment

Do not forget about the seriousness of adjusting the relay - this is a delicate procedure that must be treated with extreme caution. One minor error in adjustment can lead to damage to the entire system, which means wasted time and money on repairs. In addition, the warranty does not provide for breakdown of the unit in such cases.

Initially, it is necessary to achieve the optimal pressure in the accumulator. This can be done by disconnecting the pumping station from the power supply and draining all accumulated liquid in the tank. Now, using a special compressor with a sensor, create the optimal pressure level in it. Then remove the cover over the relay, obtaining full access to the small and large adjustment spring.

Installation minimum pressure is achieved by turning a large spring: to increase the indicator - clockwise, to decrease it - counterclockwise.

As you can see, you can handle most of the problems yourself, without the help of specialists. This will help you save money and, most importantly, give you a new experience in working with pumping stations.
