摘　　要：油气企业所用往复式压缩机所处工作环境恶劣,运行风险大,失效概率高,故进行往复式压缩机的失效研究具有重要意义。基于故障树理论,对引起往复式压缩机失效的多种因素进行分析,建立了失效故障树,并通过对故障树的定性分析得到了引起压缩机失效的21个最小割集,同时通过定性分析最小割集的发生概率来确定顶事件的发生概率。Reciprocating compressor used in oil and gas companies work in a bad environment.Its operating risk and failure probability are high.Therefore,a failure study to reciprocating compressor is important.Based on the fault-tree theory,various factors that cause reciprocating compressor failure are analyzed and the fault tree for failure is established.Twenty-one minimuml cut sets that bring about the failure are obtained through qualitative analysis of fault tree.Meanwhile,the probability of top event is determined by qualitatively analyzing the occurrence probability ofminimal cut sets.
