 压力脉动:

  1配油盘与缸体或柱塞与缸体之间磨损，内泄或外漏过大

  2．对于变量泵可能由于变量机构的偏角太小，使流量过小，内泄相对增大，因此不能连续对外供油

  3．伺服活塞与变量活塞运动不协调，出现偶尔或经常性的脉动

  4．进油管堵塞，阻力大及漏气

  排除方法：

  1．磨平配油盘与缸体的接触面，单缸研配，更换柱塞，紧固各连接处螺钉，排除漏损

  2．适当加大变量机构的偏角，排除内部漏损

  3．偶尔脉动，多因油脏，可更换新油，经常脉动，可能是配合件研伤或憋劲，应拆下修研

  4．疏通进油管及清洗进口滤油器，紧固进油管段的连接螺钉

  噪声：

  1．泵体内留有空气

  2．油箱油面过低，吸油管堵塞及阻力大，以及漏气等

  3．泵和电动机不同心，使泵和传动轴受径向力

  排除方法：

  1．排除泵内的空气

  2．按规定加足油液，疏通进油管，清洗滤油器，紧固进油段连接螺钉

  3．重新调整，使电动机与泵同心
