The "dry" and "wet" critical speeds of multistagecentrifugalpump rotor are quite different. The calculated and measured critical speeds are in good agreement.
多级离心泵转子的干临界转速与湿临界转速差别较大,计算值与试验值基本一致。

The FE analysis to the rotor of a multistagecentrifugalpump has been studied based on the software ANSYS. The entity model and FE model of the rotor are built for the static and modal analysis.
