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 water pump, shaft bending, poor co-ordination. Approach is to examine and take appropriate measures, repair, adjustment or replacement. ) Vibration frequency is n times the operating speed. Pressure pulsation, no center, housing deformation, seal friction bearings or basic resonance, pipes, machine resonance, the treatment is the same (4) wzb vortex self-priming pump, reinforced foundation or piping. ) Vibration frequency is very high. Friction shaft, seals, bearings, not precision, bearing jitter, undesirable shrinkage fit or the like. (5) the bearing cap is connected to the left and outside the fastening bolts. (6) The first stage impeller even his big mouth together key ring and the shaft installed. (7) the first stage in the middle along with the guide wing vertical multistage water pump repair, small mouth ring be installed, by the middle of the vertical multistage centrifugal water pump centering spigot, in order to strengthen the seal to prevent leakage, you should Mouth add a layer of paper pad, in order to stabilize the middle, temporarily in the middle of the pad beneath a wedge (wedge should be paired) or other pad. wzb vortex self-priming pump, water pump, water pump Xin Cheng (View) provided by Hebei Xin-pump factory.
