HR 1100A automatic suction pump failure, what is the reason why the motor has been working

1. There is no reaction after the circulating water treatment self-priming pump unit is connected to the power supply.

Most of this is caused by open circuits in the power plug, power leadouts, and motor windings.

2. The self-priming pump of circulating water treatment is difficult or unable to start, and is accompanied by a "buzzing" sound.

If the motor runs quickly, it means that the starting capacitor or starting winding is damaged, and the capacitor of the same capacity should be replaced or the starting winding should be repaired; If the motor is stuck, it is mostly due to the mechanical failure of the motor and pump head, such as bearing damage, impeller jamming, etc.

3. The motor can run, but the speed cannot be reached, and the casing is overheated and has a burning smell.

Kunshan Mikawa Hiroshi believes that most of this failure is caused by a short circuit in the motor winding, and the motor should be disassembled and repaired by welding, jumping, isolation, rewinding and other measures depending on the damage.

4. High noise and vibration during operation.

The self-priming pump is faulty, the motor keeps working, what is the reason? The electronic motor has been working to prove that the power supply is on, you don't have to work all the time, if it is a situation that cannot be avoided, that is, the power switch is broken, just overhaul the power switch.

Sorry, I didn't pay attention to see that the generator drove the pump, I thought it was just two devices used at the same time. If the generator is equipped with a water pump, the voltage stabilizing device must be installed, and the voltage stabilization here refers to the voltage imbalance; In addition, if the starting current of the pump is too large, auto-coupling step-down start, star-delta start, soft start, and frequency conversion start can be used, depending on the cost, choose different schemes.

H8-1100A automatic suction pump faulty motor has been working, that is, the fault of other parts, the motor is not faulty, check the other parts and components to see if there is a problem.

The reasons why the fully automatic suction pump motor has been working are as follows.

It is possible that the solenoid valve is faulty, and then it cannot be closed, causing the pump motor to absorb water.

In fact, if the automatic suction pump fails, the motor has been working until then, which means which place is the switch? The so-called place where this can only be a switch switch, he is always open now.

It is possible that the self-priming pump line is short-circuited, causing the motor to be working all the time, and you disconnect the power supply to detect and repair it.

If the motor is working it may be damaged, it is recommended that you break it.

If the automatic suction pump fails, the motor has been working, it is likely that the starting switch is broken, and the switch is equivalent to a short circuit.

The faulty motor of the fully automatic suction pump has been working.

Solution to the failure of the self-priming pump motor:

1. The pump still does not work after the power is turned on.

It may be caused by the power plug or line not being able to drive, short circuit, etc.

2. It is not easy to start or there is noise when starting.

If the motor can run normally, it means that the starting winding is damaged, and the capacitor of the same capacity should be replaced or the starting winding should be repaired; If the motor is stuck, it is caused by the failure of the motor and pump head, such as bearing damage, impeller stuck, etc.

3. The motor can run, but the speed is slow, the casing is overheated, and there is a burning smell.

It may be caused by a short circuit in the motor, and the motor should be disassembled to see the severity of the damage.

4. The noise and vibration are large during operation.

Most of them are damaged bearings or improper fit between the bearing and the casing, and the motor needs to be disassembled for inspection, and if the bearing is damaged, it should be replaced; If the bearing "runs the outer circle", the mating surface of the pump casing can be chiseled; If the bearing "runs the inner circle", the wear part of the motor shaft can be chiseled treatment, and if the wear is serious, the method of surfacing welding and then turning can be adopted.
