Assembly of centrifugal pump coupling

XINLAN analysisCouplingAlso known as the back wheel, it is a special part used to connect the motor and the centrifugal pump.Commonly used couplings for single-stage centrifugal pumps are mostly flanged discs. The rotation center lines of the two shafts connected by the coupling should be on the same horizontal line. Therefore, when assembling the motor and the centrifugal pump, the two The half coupling is aligned.

Finding the coupling is a very important job in repair and assembly work.The quality of the alignment has a great influence on the normal operation of the centrifugal pump.When the alignment quality is poor and the alignment error of the two halves of the coupling is large, a large additional stress will be generated between the shaft and the coupling, abnormal noise and vibration will occur, which will cause the coupling to heat up and affect The normal operation of the centrifugal pump, and even equipment accidents.

The pumps that need to be equipped with couplings are: single-stage single-suction centrifugal pump, GC boiler feed water pump pump, self-priming centrifugal pump
