摘　　要：随着汽轮机容量以及缸体结构尺寸越来越大、尤其是大容量的半转速机组的高中压缸受设计机构及设备加工能力的限制,汽缸在组装状态时上下半隔板定位面轴向错位较大。文章着重研究弱刚性设计的高中压缸在组装时的变形情况,分析变形原因,提出解决措施。For steam turbine with larger capacity and physical dimension,especially due to restriction of its designed structure and the machining facilities,there is visible axial discrepancy at the positioned surface of upper and lower diaphragm of the high-capacity half-speed steam turbine HIP casing.During assembly the article focuses on researching the deformation of the low-rigidity HIP casings,analyses the reasons cause the deformation with the method of solving the problem.
