Horizontal multi-stage centrifugal pump fault analysis and solutions
Dec 01, 2016

1, horizontal multistage centrifugal pump fault: pump water slow

Failure analysis: front liners with the impeller gap, water pipes do not seal air, emptying full.

Solution: adjustment, adjust the water pipes, installation of vacuum devices.

2, horizontal multistage centrifugal pump fault: low water pressure, flow

Failure analysis: there is air in the pump, the impeller and the former clearance of the lining, clutch close tightly, or liner wear of the impeller.

Solution: gas, emptying the pump adjustment, adjusting clutch friction plate gap, replacing the impeller or liner.

3, horizontal multistage centrifugal pump fault: pump wears out faster

Failure analysis: poor construction environment, long transmission distance, into the water.

Solution: replace the battlefield, add Afterburner unit, shorten the inlet pipe length of cavitation.

4, horizontal multistage centrifugal pump fault: pump vibration

Failure analysis: pump misalignment, unbalanced impellers, shafts and diesel engine bearing damage.

Solution: adjust the leaf rotation concentricity, balance test, replace the bearing.

5, horizontal multistage centrifugal pump fault: pump does not suction

Failure analysis: pouring water, pump enough air it cannot discharge, suction pipe leakage, large front liners with impeller clearance.

Solution: continue pouring water, check whether the pipeline leak, adjust the clearance between impeller and front liners.
