1. What is the main reason why the motor for the deep well pump is running, but the pump does not produce water?

The water level is too low and the pump cannot absorb water. The treatment method is to add a section of pump tube and drive shaft.

The treatment method of the water filter network is to hang the deep well pump from the well, and reinstall after clearing the water filter blockage.

The pump section is extended into the deep well excessively. The treatment method is to raise the pump section by one to two pump pipes.

The clearance in the pump section is too large. The treatment method is to adjust the impeller axial clearance.

Impeller damage treatment method is to hang out the pump section to replace the impeller.

3. What is the main reason for the insufficient pump head of deep wells?

Excessive gap in the pump section The treatment method is to hang out the pump section and adjust the axial gap of the impeller.

Impeller damage treatment method is to hang out the pump section and replace the impeller.

4. What are the main causes of vibration during the operation of vertical deep well pumps and motors?

The main reason for the vibration of the water pump and the motor during operation is generally caused by the wear of the transmission shaft. The treatment method is to hang the deep well pump device from the well and replace the worn transmission shaft.
