The pump is powered and buzzing, but the water can t be pumped.

The pump is energized and buzzing, but the possible reasons for not being able to pump water are as follows:

Water source problems: insufficient water sources, water levels are too low, and pipes are blocked, etc., which will cause the pump to fail to pump water normally.

Blockage of the inlet hole of the pump body: The blockage of the inlet hole of the pump will affect the water flow, resulting in the inability of the pump to pump water normally.

Damaged Pump Impeller: The impeller of the pump is worn or damaged and cannot work properly, which can also cause the pump to not pump water properly.

Unstable power supply voltage: The pump needs a stable voltage when it works, and if the voltage is unstable or the wire is damaged, it will also cause the pump to not work properly.

Solution: Check whether the water source is sufficient, whether the water level is too low, whether there is a pipe blockage problem, etc.

Disassemble the pump body to clean the water inlet hole.

Check the impeller of the pump for damage and if there is a problem that needs to be replaced or repaired.

Check whether the power supply is stable and whether you need to replace the wires or replace the regulated power supply.

If the pump doesn't buzz after being energized, it may be that the pump is malfunctioning. Generally speaking, there is a high possibility of damage to the starting capacitor. If you know how to check and repair it yourself, you can check the starting capacitor yourself.

It is also possible that the water pump coil is damaged.

It is recommended to send it to a professional repair shop for inspection and repair.

Depending on whether the pump is single-phase or three-phase, the single-phase may have a bad starting capacitor or the pump is stalled. The three-phase may run out of phase or turn in the opposite direction, and then it will be stalled. In case of power failure, the ground inspection or disassembly check whether the pump is stalled (can be freely coiled), and the power transmission is to see the steering current measurement and judge the fault.

First of all, check if the pump can be turned up?

That is to say, when the power is not transmitted, use the hand plate to dial the impeller of the pump to see if it can rotate normally.

Confirm that there is no problem, and then power it on and try it.

There is also a situation where there is too little water, which does not go beyond the top of the impeller at all, and only sucks up the air, so it cannot pump water at all.

The pump is energized and buzzing, if it is confirmed that the motor is running properly, check the pump and inlet line.

There are many reasons for this. There may be a lack of phase (if it is a three-phase electric).

Reversals are possible.

1. One is that the load is too large, which causes the motor to stall and run, resulting in current sound. 2. There is also a kind of rotor of the motor due to vibration and other reasons and the stator wall is attached together, caused by a short circuit of the magnetic circuit. A water pump is a machine that transports or pressurizes a liquid.

It transmits the mechanical energy or other external energy of the prime mover to the liquid, so that the liquid energy increases, and is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal, etc., and can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of pump performance include flow, suction lift, head, shaft power, water power, efficiency, etc.; According to different working principles, it can be divided into volumetric water pumps, vane pumps and other types. The positive displacement pump uses the change of the volume of its working liter chamber to transfer energy; Vane pumps use the interaction between noisy rotary vanes and water to transfer energy, and there are types of centrifugal pumps, axial flow pumps and mixed-flow pumps.

Summary. Hello, there are many reasons why the pump does not water:

1. Some pumps need to be diverted with water.

2. The inlet pipe is blocked.

3. Air leakage from the inlet pipe.

4. The impeller fastening screw is loose.

5. The impeller key is not installed or the top wire is loose.

6. The motor is reversed. Wait.

Why does the pump keep ringing and not pumping?

There may be several reasons why the pump does not run after it is energized:

1.Motor Damage: Motor damage may cause the pump to not function properly. Check whether the motor is damaged or burned, and you need to disassemble the motor shell for inspection or replace the motor.

2.Stuck rotor: The pump rotor may be stuck or clogged, hindering the normal operation of the pump. The pump needs to be disassembled to clean the rotor, and it is also necessary to check whether there are any foreign objects stuck in the pump.

3.Power line failure: Check whether the power line is affected by short, medium and open circuits, etc., and repair or replace the power line if necessary.

4.Capacitor damage: Damaged capacitors can also cause the pump to not function properly and the capacitor needs to be replaced.

If none of the above methods can solve the problem, it is recommended to contact professional maintenance personnel for maintenance.

Hello, dear, happy to answer for you, there are several common faults in dear.

1. The voltage is too low to cause the motor to fail, and the reasons may be as follows: 1. The power load of the power grid is too heavy, and the transformer capacity cannot meet the requirements of peak power consumption. The electric box can be installed with an undervoltage protector to observe the voltage fluctuation range 2, the distance is too far, the wire and cable selected wire diameter cross-sectional area is too thin and there is a high voltage drop, increase the cross-sectional area of the wire 3, the power supply radius distance is too long, just at the lowest voltage at the very end.

Unable to start the pump electrician in the maintenance of high-voltage power transformer, electrical circuit fault 1, whether the internal wire of the pump is broken, can use the multimeter buzzer to detect the line on and off 2, the capacitance is insufficient to start the pump, this fault is manifested as the motor buzzing does not turn, capacitance without capacity motor will stop running with a sound. The capacitance file of the multimeter detects whether the capacitance is normal, pay attention to the need to discharge before testing, and use a screwdriver or needle-nose pliers at both ends of the capacitor line to short-circuit. When the two ends of the capacitor are shorted, the sound is loud and brittle, and the capacity is sufficient.

The sound is small or even not, the capacitor fails 3, the internal coil of the pump is burned out and the circuit is broken, and the resistance can be tested with a multimeter resistance file, and the normal resistance value is generally C+R=S. That is, the sum of the two smaller windings is approximately equal to the maximum winding, if the power trips, the coil is short-circuited between turns 4, the pump of the pressure tank may have the fault phenomenon that the pressure switch does not reset, disassemble and carefully observe the discharge at both ends of the capacitor with a screwdriver, the failure of the mechanical part, this fault is generally a bearing problem, due to the problem of use time caused by lack of oil, or the life of the bearing expires. The performance fault is that the motor buzzes and does not turn the professional maintenance of the pump is more complicated, but the home only needs to master a few elements to deal with the fault.

Toggle the cooling fan first, if there is an obstacle, it means that the bearing is faulty, and add lubricating oil; Flip the fan easily without starting, check the capacitance, check the line on and off; There is no fault at all, the motor itself must fail, send it to the repair department for repair or buy a new one, I hope my answer can help you, I wish you a happy life and good health!!

Summary. Low voltage will cause this problem, and the problem of supplying power to the pump with the working voltage of the pump will be solved.

When working, it buzzes, but it can't pump water, which is because you didn't put all its entire fuselage into the liter water and didn't seal it well, either there is a problem with the impeller of the submersible pump, or the positive and negative poles of the submersible pump are connected to the opposite place.

It may be that the impeller is stuck and can not be opened for a long time, otherwise the motor will burn out and try to run on the water surface without load, or pull the impeller by hand to see, if the impeller does not move, and there is nothing wrong with the appearance, it may be that the bearing is locked and needs to be replaced.

It may be that the rotor shaft of your water pump is broken, or the water blade is stuck, just take it out and reinstall it.

The pump motor does not rotate and buzz, and you can first judge from the buzzing sound whether the power supply is out of phase or the pump motor is stuck. The hum of the power supply will be louder and hoarse with vibrations. If the pump motor is stuck, the hum will be quieter and the sound will be crisp.

If it is difficult to judge from the sound, you can judge it during maintenance.

1) The buzzing sound of the pump motor is likely to be damaged by the starting winding, and if the pump motor is damaged by the starting winding, the starting winding should be repaired.

2) It is very likely that the load is too large, which leads to the stalled operation of the motor and then forms the current sound.

3) It may be that the rotor of the motor is bonded to the stator wall due to vibration and other reasons, and the magnetic circuit is short-circuited, if it is due to this situation, it is necessary to contact the maintenance personnel for maintenance.
