Horizontal multi-stage centrifugal pump fault analysis and solutions
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.
