The following is a listing of the common faults and treatments of slurry pumps.

Common faults of slurry pump

1. Pump does not turn.

2. Insufficient pump flow.

3. Leak at packing.

4. Pump vibrates.

5. Loud noise.

6. Bearings are hot.

7. Bearing life is short.

Causes and Solutions

1. The density of the medium is not uniform. The uneven density of the medium causes the pump to vibrate when it is just started. Before starting the machine, blow the medium with high pressure air.

2. The pump is not installed horizontally. The level of the pump body should be checked during installation and operation.

3. Cavitation can unbalance the impeller of the pump. The installation height should be lowered, the outlet valve should be reduced, and the inlet resistance should be reduced.

4. Suction pipe air intake is uneven. The feeding situation of the pump should be improved to strengthen the uniform stability of the intake air.

5. Pump bearing clearance is large. Excessive bearing clearance will cause the pump to vibrate. If the pump shaft and motor shaft are not concentric or the bearing is damaged, it should be dealt with in time.

6. If the cold water is not turned on or the cooling water tank is blocked, the cooling water function should be turned on or the cooling water channel should be cleared.

7. Equipment lubrication is poor. The amount of lubricating oil should be adjusted according to the instructions.

8. The lubricating oil is not clean and there are impurities in the oil. The bearing should be cleaned and replaced with lubricating oil.

9. The lubricating oil is not clean and there are impurities in the oil.

10. The thrust bearing is in the wrong direction. Adjust thrust bearing orientation for inlet pressure conditions.

11. The air outlet of the bearing is blocked, so that the hot air in the bearing housing cannot be discharged, which increases the temperature of the equipment. The air outlet should be cleaned.
