基于风险矩阵的泥浆泵关键部件的风险分析

摘要

The reliability of the slurry pump is directly related to the safety of the drilling process of ex-ploration and development.The failure of its key components will seriously affect the performance of mud pump working.According to the operation of mud pump and the experts'experience, a failure mode and effect analysis ( FMEA) table of crosshead guide plate assembly is established and 11 failure causes are educed.On this basis, the causes and risks of failure are analyzed and prioritized by risk matrix and Bor-da method to get the dominant and critical failure causes.As a result, decision makers can work out cor-responding measures to reduce the frequency of failure occurrence.%泥浆泵的可靠性直接关系到勘探开发钻井过程的安全，其关键部件出现故障将严重影响泥浆泵的工作性能。根据F1600宝石泥浆泵的运行状态，结合专家经验，建立了泥浆泵的十字头导板总成故障原因的分析表，得到导致十字头导板总成故障的11个故障原因；在此基础上，通过矩阵分析法和Borda序值法对故障原因和风险进行了分析和排序，得出了其主要和较大风险的故障原因，以便决策者及时通过采取相应措施降低故障的发生频率。
