高腐蚀高振动工况下压缩机气缸泄漏致因与防控研究OA

To address the issues of unclear causes and insufficient prevention and control basis for cylinder leakage accidents of reciprocating compressors under overseas high-corrosion and high-vibration operating condi-tions,this study collected 69 accident cases from overseas projects of a petrochemical company over the past 10 years.A HAZOP-FMEA integrated analysis strategy was proposed and validated,centered on using process pa-rameter deviations as a guide to trace component failure modes and causes directionally,thereby overcoming po-tential analysis gaps in traditional methods.Furthermore,by integrating the Bow-tie diagram and the analytic hi-erarchy process(AHP),a systematic risk analysis model of"qualitative identification-path construction-quanti-tative assessment"was constructed and systematically applied to the risk identification and assessment of recip-rocating compressor cylinder leakage.The results showed that through the HAZOP-FMEA integrated analysis,10 underlying causes were identified,with accidents mainly occurring in the cylinder body and cylinder head,and design defects being common triggers.Quantitative analysis further determined that corrosive environment,overload operation,and vibration were three key causes,with corrosive environment having the highest weight(0.225 0),making it the primary risk under overseas high-corrosion conditions.Based on this,graded quanti-tative prevention and control measures were proposed from the dimensions of material selection,condition moni-toring,operational procedures,and personnel management,providing actionable solutions for targeted safe oper-ation and risk prevention of compressors under overseas high-corrosion and high-vibration conditions.
