有些机手把失去压力的齿轮式液压油泵随意报废,实在可惜。一般这类液压油泵失去压力的原因主要是轴套端面磨损或卸压片密封圈失效,从而导致油泵严重内漏,使油泵建立不起工作油压。对于这样的废泵,只要在后轴套下面加垫薄铜片,就可排除故障。若再增加一套传动装置,这个废泵就会成为一个很好的加油泵。传动装置有两种型式:一种是以电动机作为动力的固定式传动装置;一种是以拖拉机动力输出轴 It is a pity that some of the aircraft fans scrap the lost hydraulic gear pump at will. This type of hydraulic pump is generally the main reason for the loss of pressure on the sleeve end wear or pressure relief piece seal failure, leading to serious pump leakage, the pump can not afford to work hydraulic pressure. For such a waste pump, as long as the backing sleeve under the padded thin copper, you can troubleshoot. If you add a set of transmission, the waste pump will become a good pump. There are two types of transmission: one is a motor-powered fixed transmission; one is the tractor power output shaft
