Coupling problem The main function of the coupling is to connect the pump and the motor to rotate together and transmit the torque. There is an air bag in the outlet pipeline. Can not work normally.This situation often occurs in large and medium-sized water pumps that use sliding bearings. Bending machine pump shaft
The outlet valve opening is too small. 2. (2) When the pump is repaired and installed on the inlet and outlet pipelines, due to the changes in pipeline displacement, especially the newly commissioned pipeline, the first time the inlet and outlet flanges are removed, the relative displacement of the flanges is very large. In severe cases, pump jams occur. Fives. (4) When replacing the pump, because the pump base does not match the foundation bolts, the holes in [...]
