摘　　要：利用FTA方法对离心泵机械密封端面故障进行分析,建立故障树并对其进行定性分析。根据结构重要度结果排序,找出机械密封端面的薄弱环节,为预防离心泵系统的机械密封端面失效提供参考。The method of FTA was used to built the fault tree and the qualitative was analysised with on failure of centrifugal pump mechanical seal faces. According to the structural important degree, we sorted the results to find out the vulnerable segments of the mechanical seal face. This article provides reference to prevent the failure of mechanical seal faces of centrifugal pump system.
