往复压缩机活塞环寿命短的原因分析及对策

CAUSE ANALYSIS ON THE SHORT SERVICE LIFE OF RECIPROCATING COMPRESSOR PISTON RING AND THE COUNTERMEASURES

对PSA装置原料气压缩机在运行过程中出现的活塞环磨损过快,使用寿命偏短等问题进行了原因分析,在设备结构方面提出了改进措施,通过控制聚四氟乙烯活塞环、支撑环的碳纤维含量,增加机械式活塞杆下沉监控装置,为科学决策检维修时机提供了依据,改进措施实施后不仅延长了活塞环的使用寿命,而且使设备本身安全性能也取得了较好效果,为装置的安、稳、长、优生产打下了良好的基础。

This paper makes a cause analysis on the problems of fast piston ring worn and the short service life of feed gas compressor in PSA unit during its operating process.It presents improving measures in equipment structure.Through controlling carbon fiber content of the piston ring and supporting ring of PTFE and adding mechanical piston rod subsidence monitoring device,scientific check and maintenance time is determined.After implementation of the improving measures,not only the service life of the piston ring is extended,but also the intrinsic safety of the device is improved,which helps to lay a solid foundation for the safe,stable,long and optimal production.
