1. The pump does not start or boot load, causes and treatment methods are as follows: (1) the prime mover or power is not normal. Approach is to check the power supply and the prime mover situation. (2) pump stuck. Approach is to manually check the Pearl vertical coupling plate moving water pump models, if necessary, the disintegration of inspection, eliminating part of the fault movement. (3) packing too tight. Processing method is to relax the filler. (4) The discharge valve is not closed. Approach is to close the discharge valve, restarted. (5) balance tube is not smooth. Approach is to clear the balance pipe. Pump vibration or unusual noise, causes and treatment methods are as follows:) vibration frequency is twice the operating speed. Misalignment, loose coupling, seal friction and casing deformation, bearing damage, supporting the resonance, the thrust bearing is damaged, bent shafts, poor co-ordination. Approach is to examine and take appropriate measures to clean water pumps, repair, adjustment or replacement. ) Vibration frequency is n times the operating speed. Pressure pulsation, no center, housing deformation, seal friction bearings or basic resonance large flow high head pump, piping, machinery Humen Peak resonance self-priming pump, treatment is the same (4), reinforced foundation or tube road. ) Vibration frequency is very high. Friction shaft, seals, bearings, not precision, bearing jitter, undesirable shrinkage fit or the like.
