The Causes And Solutions Of The Common Failure Of Slurry Pumps

Following shared by Slurry Pumps Supplier China.

1. Fault: abnormal sound in the centrifugal pump, no water pumping.

Reason: suction pipe resistance is too large. Excessive suction height. Air enters the suction pipe. The temperature of the drain is too high.

Solution: check whether the suction pipe is blocked. Clean bottom valve and lower liquid temperature or suction height.

2. Fault: pump vibration

Reason: pump shaft and motor shaft are different. Impeller unbalance. Bearing clearance too large.

Solution: adjust the pump and motor so that the axis alignment. Impeller through the balance test, the unbalanced weight requirements in about 3 grams. Replace the bearing.

3. Fault: centrifugal pump bearing heating

Reason: bearing lack of oil or oil viscosity too big impact on lubrication. Bearing wear clearance is too large. The pump is different from the motor.

Solution: go for it. Change oil or oil with low viscosity. Replace the bearing. Adjust pump and motor to ensure concentric.

4. Fault: the centrifugal pump is noisy

Reason: centrifugal pump and motor installation of different core. Centrifugal pump or motor bearing wear, produce runout.

Solution: adjust the centrifugal pump and motor to ensure concentric. Replace the bearing.

5. Fault: the Slurry Pump does not absorb water, and the pressure gauge beats violently.

Reason: insufficient water infusion. There is air in the pump. Leakage from suction and gauge pipes.

Solution: fill in enough water. Check the pipeline to eliminate air leakage.
