摘　　要：本文通过利用沈鼓离心压缩机优化选型程序对压缩机设计参数进行分析,对机组转子、定子结构进行优化设计及力学分析,并通过有限元分析对设计结果进行验证。验证结果表明:在满足机组刚性、强度的情况下,通过卡环结构设计,可以减轻直径为1 400mm的筒型离心压缩机机壳质量;同时设计了大型机组芯子拆装工具,确保大型芯子(含内机壳、隔板和转子)的整体拆装的顺利完成,该机组可以满足20t级以上的端盖拆装设计。This paper analyzes the design parameters of the centrifugal compressor using CAL300 software by simulating structural strength of the stator and rotor. The simulation results show that the volute weight of the centrifugal compressor impeller with the diameter of 1400mm could be reduced through designing a snap ring without changing the performance and integrity of the compressor. This paper also presents a disassembly device for the large core assembly, which includes inner casing, diaphragm, and rotor. The disassembling device can be used for the large end cover with over 20 ton.
