【正文】 guide the production. In this paper, the finite element analysis is made to the structure of the impeller by ANSYS software, the stress and strain and deformation of the impeller are gained under the load. From the results, we can see that the force and deformation of the impeller within a safe range under any form of load. Keywords: multistage injection pump, impeller, finite element analysis 中國石油大學（華東）本科畢業(yè) 論文 目錄 第 1 章 緒論
