Reasons for the high consumption of centrifugal pump operation** and inspection processing

Reasons for high power consumption in centrifugal pump operation:

1, the impeller and wear ring, impeller and pump casing contact, resulting in friction.

2. The operation flow is too large.

3, increased liquid density.

4, sealed tightly, too dry.

5, bearing damage or no lubrication.

6, the pump shaft bending.

7. Coupling misalignment or axial clearance is too large.

Large power consumption inspection and treatment in centrifugal pump operation:

1, the impeller and the wear ring, the impeller and the pump casing contact friction, if friction and shims to adjust the gap.

2, check the valve, reduce the flow.

3, check the flow and liquid density is too large.

4, check the seal is too tight, too dry.

5, replace the bearings, add lubricants.

6, check the replacement of bearings.

7. Check if the coupling is not centered or the axial clearance is too large.
