摘　　要：某型电动泵组件在例行检查时,多次发现液压泵与电机结合面出现渗油现象。通过对出现渗油现象的电动泵组件进行分解检查,确定了结合面渗油故障的原因是石棉垫无法有效密封电机和液压泵结合腔处积蓄的液压油。为有效解决该问题,制定了以下措施:石棉垫进行浸脂处理;增加拧紧力矩要求;液压泵与电机装配时,清洗液压泵和电机结合端面。经过试验验证,以上措施可有效解决该问题故障。During routine inspection of a certain type of electric motor pump component,oil leakage was found on the joint surface of hydraulic pump and motor for many times.Through disassembly and inspection the electric motor pump components with leakage,it was determined that the reason for oil leakage fault on the joint surface was that the asbestos gasket could not effectively seal the hydraulic oil accumulated in the joint cavity of the motor and hydraulic pump.In order to effectively solve this problem,the following measures have been formulated:asbestos pads are subject to grease treatment;requirements for tightening torque are increased;when the hydraulic pump and motor are assembled,the joint face of the hydraulic pump and motor is cleaned.Through test verification,the above measures can effectively solve the fault.
