摘　　要：高温下动设备经常会发生事故。本文结合实际案例,分析了高温蒸汽管道对离心压缩机进口受力问题。基于CaesarⅡ软件进行建模受力分析,提出了调整管道支架及静设备支座来减小管口推力的方案,改变管线走向来减小管口推力的方案,管口设置膨胀节来减振和减小管口推力的方案,对于动设备进出口管线的结构设计具有实用价值。High temperature, moving equipment often accident. This paper combines the actual case ,The problem of high temperature steam pipeline on the inlet of centrifugal compressor is analyzed, Force analysis of modeling based on CaesarII , The scheme is proposed to reduce the nozzle thrust by adjusting the support of the pipe and static equipment, The scheme is proposed to reduce the nozzle thrust by changing the pipeline direction, The scheme is proposed to reduce the nozzle thrust and vibration by setting expansion joints, The design of the import and export pipeline for the moving equipment is of practical value.
