摘　　要：针对辽阳石化蒸汽裂解装置离心式压缩机在正常运行过程中出现的润滑油系统压力异常波动现象,通过对压缩机工艺设备影响因素逐一排除分析,确定润滑油系统自力调节阀故障是引起油压波动的主要原因,采取针对性检修和技改措施后,最终解决了这一顽疾。During the normal operation of centrifugal compressor in the steam cracking unit at PetroChina Liaoyang Petrochemical Company,abnormal pressure fluctuation occurred in the lubricating oil system.Through the exclusion analysis of the influential factors of process and equipment,it was concluded that the failure of self-regulating valve of the lubricating oil system was the main reason for the pressure fluctuation.This problem was completely solved after carrying out targeted check and repair and taking corresponding technical improvement measures.
