| Abstract: | Abnormal vibriation reasons of multistage centrifugal pumps were analyzed,then some measures were carried out,such as rationally adjusting the clearance of thrust,clearance of balance disk,clearance between impeller ring and pump mouth ring,checking concentricity between direct export of seal cavity and pump body,welding the place where breakage happened in the first stage impeller casing because of severe corrosion.At last,the pumps can run very well. |
