What should I do if there is no pressure in high-pressure water? It is recommended that you go to a professional repair place to repair it.

What is the problem that the high-pressure water pump has no pressure.

1. It is possible that the nozzle is subject to serious wear, and there will be no pressure, and the nozzle has to be replaced if it is seriously worn.

2. It may be that the water filter is blocked, which will lead to insufficient water intake, so take out the filter and wash it with clean water.

3. It is possible that the internal components of the high-pressure water room pump are worn, resulting in no pressure, if the wear is serious, the new high-pressure water pump has to be replaced.

1. The pressure cannot go up due to the inhauling of air in the high-pressure water pump or water inlet pipeline, so you only need to intermittently pull the trigger of the high-pressure water gun, reduce the working pressure of the high-pressure cleaner and run for a while until a stable pressure is generated;

2. If the pressure is not up due to insufficient water supply, first check whether the water level of the water tank is too low, whether the water inlet pipe has leaked out of the water surface and whether the water inlet pipe is leaking and taking rock, at this time, it is necessary to add water to the water tank or replace a new water inlet pipe; If it is a non-self-priming pump, it is necessary to check whether the pressure of the water source is sufficient and whether the inlet flow rate meets the requirements of the pump;

3. The pressure cannot go up due to the blockage of the water inlet filter, so you only need to clean the water inlet filter.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately Hello, I am happy to answer for you. The reasons why the circulating water pump cannot be opened are probably as follows: 1. The water pump has not been running for a long time, which makes the impeller and sealing parts bonded, resulting in motor blockage; Before starting the machine, the water pump should be coiled to confirm that the rotation is flexible before starting.

2. The pump itself is defective, and there is a dead center when it is coiled, so it should be dismantled to check whether the parts of the pump are damaged. 3. Electrical fault, check whether the motor and line have phase loss fault, whether the protection system has any misoperation, and the test machine without pressure after exclusion may be the following conditions: 1. The pipeline pressure may be caused by the leakage of a certain part of the pipeline, so that the system pressure is reduced; At this point, you can close the outlet valve and check the pressure.

2. Lack of water, insufficient water source in the pipeline is also one of the reasons for insufficient pressure, at this time, the noise of the pump can be heard after opening the macro pin, and the sound of gradually closing the outlet valve will gradually decrease. 3. Impeller corrosion or impeller mouth ring wear; 4. Judge whether the pressure gauge is normal.

Hello, glad to answer for you. Hello, you can check some of the information I sent you above [happy].

Questions. The water pump starts with a lot of effort and will automatically shut down after a few more clicks.

After the water was introduced, Weng Xia stopped.

Centrifugal switch is newly replaced.

Just changed the power cord, it was better, it could start three or four times in a row, and then it stopped again, and it could be plugged in after a while.

It is to start the pump motor to carry the large centrifugal switch after the water is introduced.

Hello, glad to answer for you. Hello, it's the soft-stop function that is turned off.

Questions. What does it mean to be clear a little thanks.

Hello, glad to answer for you. Hello, you need to change a new power supply to try [happy] I hope the above will help you If you are satisfied with me, please give me a thumbs up.

There are several reasons why the pressure reputation is too small: 1. If the inlet of the pump is full, when there is no pressure in the pump used for the first time, it is likely that the pump is reversed.

2. There is air in the water supply pipe and pump body. 3. The suction range is too large. 4. The resistance loss of the inlet and outlet pipes is too large.

5. The pump inlet is blocked or the water inlet is insufficient. 6. The motor speed of the centrifugal pump is too low.

The pressure of the pump is not bent on the fiber, and the water in the pump and the pipeline is very hot, the frequency conversion control display is normal, the motor can rotate The pipeline is blocked or there is a valve sock imitation door that is not opened, and the water will heat up if it idles in the pump casing.

If the pipeline is clogged or the valve is not opened, the water will heat up if it idles in the pump casing.

The pressure of the two pumps will definitely increase, but the second pump should not be installed on the outlet of the previous pump, and the outlet of the two pumps should be connected to the same mother pipe.

Hello dear, glad to answer for you! The reasons why the lead of the pump cannot get up the pressure are: 1. If the pump inlet is a pool, if the pump is not pressurized or does not produce water for the first time, it is very likely to be caused by the pump reversal.

The problem can be solved by setting the program of the controller or by changing the phase sequence at the motor switch. 2. There is air in the inlet pipe and pump body 1, the centrifugal pump is not filled with enough water before starting, sometimes it seems that the irrigated water has overflowed from the vent hole, but the air is completely discharged without rotating the pump shaft, resulting in a little air remaining in the inlet pipe or pump body 1The impeller rotates unbalanced, the coupling is not tight enough, and the parts are loose and broken, resulting in large vibration of the water pump.

However, the Huai cavity bureau can solve these problems by means of adjustment, reinforcement, repair or replacement. 2.Mostly because the packing is pressed too tightly, the cooling water cannot enter the packing, or the shaft surface is damaged.

Measures such as relaxing the filler of the round rock and cleaning up the sealing and blockage can be taken. Wear-out packing must be replaced with a new one. Before installation, soak in the oil and fill it in one circle at a time, and the cuts should be staggered, so as to reduce water leakage.

3.The pump is not full of water or there is air in the inlet pipe. If this is the case, fill the water and pump the air out of the pipes.

1. Booster pump.

What is the reason for not being able to pump water.

1. The booster pump cannot pump water, which may be caused by the low water level. If the tap water level is lower than the impeller level of the booster pump, the water will not be pumped. You can wait until the water level rises before using the booster pump.

The booster pump cannot pump water, or because there is no water in the pump, so make sure that there is enough water in the pump and pipeline when the booster pump pumps water. In this case, we can fill the pump with water.

2. The booster pump cannot pump water, which may also be caused by the blockage of the inlet and outlet pipe diameters. We turn off the power of the booster pump, clean it, and then reinstall it and debug it normally. If the booster pump cannot pump water, it may be that the product is faulty, and you can ask a professional to repair it.

Second, what should be paid attention to when installing a booster pump.

When we install the booster pump, we first check whether the product parts are loose, damaged, or blocked. When installing, it should be installed according to the installation method described in the product description, and it should be noted that the direction of the arrow of the pump body should be the same as the direction of the water flow. The booster pump pipes should be tightly connected to avoid the problem of air leakage in the pipes.

A valve switch can be installed at the inlet pipe of the booster pump, and a pressure gauge can be installed at the outlet.

This is more convenient for everyone to use and maintain. The first time you use the booster pump, fill the pump with water.

Pressure pumps not getting water can be caused by a variety of reasons. To solve this problem, you can check and deal with it from the following aspects:

Venting: Make sure there is no air inside the pump. Air affects the pump's self-priming ability. Open the pump's vent valve or fill the pump with liquid to expel air.

Check the inlet pipe: Check the inlet pipe for blockages, air leaks, or damage. If there is a problem, clean up the blockage, repair the leak and replace the broken pipe.

Check the working condition of the pump: Make sure the pump is in good working condition. Check whether the motor is operating normally and whether the speed of the pump meets the design requirements. Check whether key components such as impellers, shafts, and seals are worn or damaged, and replace damaged parts in time.

Check the water absorption depth: Check whether the water absorption depth of the pump exceeds the self-priming range of the pump. If the self-priming range is exceeded, the suction depth needs to be reduced or the pump can be replaced.

Check the power supply and voltage: Make sure that the power supply is normal and the voltage is within the allowable range. Low voltage can cause the motor speed to drop, affecting the pump's pumping capacity.

Check the water source: Check if the water source is sufficient, if the water source is insufficient, you need to find other water sources.

Check the installation and commissioning of the pump: Make sure that the pump is installed correctly and that the connection between the pump and the system piping is tight. At the same time, the pump is properly tuned according to the actual needs of the system to meet the pumping requirements.

Choose the right pump: Choose the right pump based on the pressure and flow requirements of the system. If the pump model is not matched, it may not provide sufficient pumping capacity. When selecting a pump, the actual needs and safety margins of the system should be considered.

Through the above methods of inspection and treatment, the problem of pressure pump not watering can usually be solved. If the problem is still not resolved, it is recommended to seek professional help for a comprehensive diagnosis and repair of the system.

Hello, I am glad to answer for you, the water pump is a self-priming jet pump This kind of pump can not be blocked at the outlet, otherwise it will cause the gas in the pump to be unable to be discharged, and the pump will naturally not be able to pump water normally. The solution is very simple: connect an automatic exhaust valve to the outlet of the water pump, install a check valve near the interface of the pressure tank, and connect the water pipeline between the check valve and the pressure tank.

That's it.

If there is a sudden lack of pressure when the pump is running normally, you can check out:

1. Check whether it is a pressure gauge.

If the indication is inaccurate, re-test, and calibrate the pressure gauge.

2. Check the inlet tube to the vacuum level.

For reference, whether there are too many inlet elbows or too high suction ports.

3. Check the reasons for electrical appliances, the electric speed is not enough, the liquid intake is insufficient, the filter cylinder is blocked, and check whether the motor is running in single phase.

4. Check the water seal of the pump body.

Reasons for insufficient flow pressure of water pump and treatment methods:

1. The inlet pipeline of the pump is blocked, and the impeller and guide vane flow channel are blocked.

Judgment method: a. Close the outlet valve, the pump can reach the rated pressure, and the pressure of the open valve drops sharply;

b. Open the exhaust valve, the exhaust pressure is lower than before or the air cannot be exhausted.

Solution: Clean up the pipeline impeller, impurities, scaling and other items in the guide vane, and replace and repair the bottom gate.

2. The voltage and speed of the pump are not enough.

Judgment method: a. Check the voltage with an ammeter and check the speed with a tachometer;

b. The frequency of the motor is low.

Solution: a. Increase and stabilize the motor voltage and increase the motor speed;

b. Increase the frequency of the motor, the best frequency is 50Hz.

3. The resistance of the pump pipeline is too large.

Judgment method: a. The outlet valve is fully open, and the outlet pressure is greater than the rated pressure;

b. The inlet and outlet pipelines are smaller than the inlet and outlet of the pump.

Treatment method: a. Reduce the system pressure, or increase the pump pressure;

b. Replace the inlet and outlet pipelines, and the inlet and outlet pipelines are greater than or equal to the diameter of the inlet and outlet pipes.

4. The gap between the rotors of the water pump is too large.

Judging method: a. The rotor is worn, the flow rate and pressure reach the rated pressure at the beginning, and the flow rate and pressure drop after running for a period of time;

b. Frequent fluctuations in pump vibration, current and pressure.

c. The pressure of the balance water pipe is super high.

Solution: Repair or replace the rotor parts, mouth rings, guide vane sleeves, and throttling devices.

5. The pump valve is stuck or cannot be opened.

Judging method: a. Close the valve to see the current and pressure changes, and then open the valve to see the current and pressure changes, in the case of no change, you can determine that the valve has a problem (the pump with water quality crystallization, this kind of problem is common);

b. See if the check valve is reversed.

Treatment: a. Replace the valve or repair the valve;

b. Reinstall check valve.

There are several reasons for the pressure to be too small: 1. If the inlet of the pump is full, when there is no pressure in the pump used for the first time, it is likely that the pump is reversed.

2. There is air in the water supply pipe and pump body.

3. The suction range is too large.

4. The resistance loss of the inlet and outlet pipes is too large.

5. The pump inlet is blocked or the water inlet is insufficient.

6. The motor speed of the centrifugal pump is too low.

Hello dear! We'll be happy to answer for you. What should I do if the pump has no pressureA:

1. Check whether the pump is reversed, the water flow and pressure are obviously small in the case of the pump reversal, if the pump is reversed, only the two phases on the motor binding post are needed. 2. Check whether the pump is exhausted; The process of exhaust is to open the exhaust valve, let the water flow naturally into the pump, if you see water flowing out of the exhaust port, then it means that the exhaust is completed, just install the exhaust port. If the pump is not vented before use, then there is air in the pump, and when the pump is running, the water passes through the inlet to the impeller and then transports out, and the efficiency will be greatly reduced.

Therefore, the pump that needs to be filled with water before use must be filled with water and exhausted before being put into use. 3. The impeller of the water pump is damaged or falls off, and the new pump is less likely to have this situation, and the pump that has been used for a long time will wear or fall off. Because the water is not completely pure, there will be some impurities in it, especially the pump for pumping sediment, the wear is more serious, and the submersible sewage pump is easy to suck small stones and then break the pump casing or impeller.

If you find that the flow rate or pressure is much lower after using the pump for a period of time, you can open the pump body to see if the impeller is damaged on the premise that there is no leakage in the pipeline or pump body. 4. Check whether there is water leakage in the pump body or pipeline, the common water leakage will appear at the connection of the pump, that is, the place of the mechanical seal, sometimes dry grinding or some other reasons, the machine seal will be easily damaged; If you are using a packing seal, then a slight dripping is normal.
