1·The "dry" and "wet" critical speeds of multistage centrifugal pump 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。
2·The FE analysis to the rotor of a multistage centrifugal pump 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.
使用ANSYS软件对一台多级离心泵的转子部件进行有限元分析，建立了转子部件的实体模型和有限元模型，对转子部件进行静力及模态分析；
