Stainless steel submersible pump operation abnormal vibration, instability reasons

The stainless steel submersible pump is made of stainless steel. The pump contact liquid is cast with non-magnetic stainless steel, so it has the characteristic of non-pollution and corrosion resistance. The use of single (three) phase power, with small size, the appearance of the United States, rust, corrosion resistance, the general acid-base seawater can be used.
Stainless steel submersible pump operation abnormal vibration, instability reasons
1, pump operation abnormal vibration, instability, the main reason:
(1) pump base anchor bolts are not tightened or loose;
(2) There is no independent support of the outlet pipe, the pipeline vibration affects the pump;
(3) impeller quality imbalance or even damaged or loose installation;
(4) damage to the pump upper and lower bearings.
2, excluding measures
(1) evenly tighten all anchor bolts;
(2) of the pump outlet pipe independent solid support, not to pump the water pipe flange bearing;
(3) repair or replace the impeller;
(4) Replace the upper and lower bearing pump
