基于故障树分析的化工运输泵的故障分析与维护

Research on Failure Analysis and Maintenance of Chemical Transport Pump Based on Fault Tree Analysis

摘要: 运输泵在化工行业的产品生产过程中起着重要作用，泵故障会引起巨大的生产损失，而泵故障类型及原因复杂，维护没有针对性，常常出现维护不到位及过度维护的现象。本文通过提取衢州华友钴新材料有限公司车间一年的泵维修记录，分析其故障原因。通过故障树分析方法，对基本事件进行划分，并计算基本事件的临界重要度，从而得到影响泵运行的重要原因，根据基本事件的重要度排序，制定相应的维护计划，提高设备的运行稳定性。

Abstract: Transportation pump plays an important role in the production process of chemical industry. Pump failure will cause huge production losses. However, pump failure types and causes are complex, and maintenance is not targeted, so maintenance is often not in place and excessive. In this paper, the pump maintenance records of a chemical enterprise for one year were extracted to analyze the cause of its failure. Based on the fault tree analysis method, the basic events are divided, and the critical importance degree of the basic events is calculated, so as to get the important reasons affecting the pump operation. According to the order of the importance degree of the basic events, the corresponding maintenance plan is made to improve the operation stability of the equipment.
