Friction welding drill pipeandCommon faults of centrifugal water pump include: water pump does not produce water; After the water pump is started, only one stream of water will not come out; The water output of the water pump is insufficient; The power consumption is too large; Vibration and noise of the water pump; Heating of the bearing; Heating of the packing; Too much water leakage at the packing, etc.

Friction welding drill pipeandCentrifugal pump its fault causes and troubleshooting methods are as follows:

One.Water pump does not produce water

Causes and exclusion methods of water pump:

1. Insufficient water diversion or incomplete air suction by vacuum pump. Can continue to water or pumping.

2. There is too much air leakage in the water inlet pipe. The flame method can be used to check and plug.

3. The pump speed is too low. Tachometer can be used to check and adjust.

4. Suction is too high. Can reduce the pump installation position, reduce the suction.

5. The rotation direction of water pump is wrong. You can find the right direction of rotation.

6. The total height of water conveyance exceeds the regulations. The installation position can be changed to reduce the water delivery height.

II.After the pump is started, only one stream of water will no longer come out.

Friction welding drill pipeandCentrifugal pump after starting only a stream of water is no longer out of the water causes and exclusion methods:

1. There are too many bubbles in the inhaled water. It can be checked whether the end of the inlet pipe is at a certain depth below the water surface.

2. The nest in the suction pipe stores air. Air can be excluded.

3. The suction pipe or suction side connection pad is not tight and has air leakage. Bolts can be tightened to adjust the gasket and block the gap.

4. The bottom valve is blocked by sundries. Can remove debris.
