氧化物注入泵故障简析

The Analysis of Oxide Injection pump Common Failure

某石化公司高压低密度聚乙烯装置(LDPE)以过氧化物为引发剂,过氧化物注入系统为装置关键系统之一。自开工以来,因过氧化物注入泵频繁出现问题,导致装置多次全线停车,损失巨大。现就其故障进行简析,提出解决措施,克服了生产难题,大大提高了装置的运行周期。

Some petrochemical company high pressure low density polyethylene （LDPE） with peroxide as initiator, peroxide injection system is one of the key systems. Since the plant start, because of frequent peroxide injection pump problem, they caused the plant interlock trip many times, This created huge loss- es. Now on the failure analysis, puts forward the measures to overcome the production problem, greatly improving the device running cycle.
