煤锁气压缩机活塞杆失效分析

Failure Analysis on Piston Rod of Coal Lock Gas Compressor

往复式压缩机活塞组件、十字头连接故障率高是化工行业压缩机面临的共性问题;本文结合某煤化工企业煤锁气压缩运行的实际情况,针对煤锁气压缩机活塞杆断裂的事故,通过对活塞杆连接部件及活塞杆断口部位的宏观检查,分析活塞杆产生断裂的原因,为同类压缩机的安装及维护工作提供借鉴。

High failure rate of reciprocating compressor piston assembly and cross connection is a common problem faced by compressors in chemical industry.Based on the actual situation of coal lock gas compression operation in a coal chemical enterprise,this paper aims at the piston rod fracture accident of coal lock gas compressor.Through the macroscopic inspection of the connecting parts of piston rod and the fracture part of piston rod,the cause of piston rod fracture is analyzed,which provides reference for the installation and maintenance of similar compressor.
