摘　　要：通过对大庆油田近5 a潜油电泵易损零部件的数据统计,应用可靠性分析理论和方法研究了易损零部件的失效规律,得出4大部件的故障率占整个机组系统的91.7%,其可靠度由小到大的次序为电机、保护器、电泵和分离器。在这4大部件中,可靠度较低的零件主要有泵轴、叶导轮、扶正轴承、胶囊和保护器轴,其中泵轴、叶导轮、扶正轴承的主要失效模式是磨损,连接螺栓的主要失效模式是断裂失效。By processing statistically the wearable parts＂ data of submersible electric pump in Daqing oil field and applying the reliability analytic theory and method. The research on invalidation rule of wearable parts was carried out and concluded finally that the fault rate of four parts is 91.7 percents in the whole unit and the reliability of separator, electric pump, protector and motor reduces in turn. The lower reliability parts are the pump axes, impeller, adjusting bearing, capsule and protector axes. The invalidation mode of pump axes, impeller and adjusting bearing is abrasion and that of connecting bolt is rupture invalidation.
