摘　　要：通过逐一分析对比,排除了压缩机入口过滤器堵塞、压缩机入口介质组分变轻、出口返回调节阀或副线阀故障等原因引起的压缩机故障,最终确定为压缩机干气密封系统中前置密封环腐蚀和压缩机螺杆及机壳腐蚀。本文对此进行分析和阐述,仅供同行参考。By analyzing and comparing one by one,the compressor faults caused by clogging of the inlet filter,lightening of the medium composition at the inlet of the compressor,and failure of the outlet return regulating valve or auxiliary line valve were ruled out.Finally,it was determined that the compressor faults were caused by corrosion of the front sealing ring in the dry gas sealing system of the compressor and corrosion of the compressor screw and casing.This article analyzes and elaborates on this for peer reference only.
