如配油盘被金属碎片、铁屑等划伤，端面漏油；变量机构中的单向阀密封面配合不好，泵体和配油盘的支承面有砂眼或研痕等。可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位。柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入；柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角，通过调节斜盘的倾角可改变泵的。 可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位，液压泵过度发热有两个原因，一是机械摩擦生热，由于运动表面处于干摩擦或半干摩擦状态，运动部件相互摩擦生热，二是液体摩擦生热，高压油通过各种缝隙泄漏到低压腔。

应重新调整压力或检修溢流阀。如果液压泵的缸体与配流盘产生偏差造成大量泄漏，严重时，缸体可能破裂，则应重新研磨配合面或更换液压泵。(2)内部泄漏过大，造成油封处压力增大，而将油封损伤或冲出；(4)泵的外接油管松动，管接头损伤，密封垫老化或产生裂纹；柱塞向上供油，当上行到柱塞上的斜槽（停供边）与套筒上的回油孔相通时，泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通，油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油。此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行。此时便开始了下一个循环。6．液压泵过热(2)输出压力过高3．输出流量波动(1)机械振动和噪声柱塞泵以一个柱塞为原理。

迫使柱塞作上、下往复运动，从而完成泵油任务，泵油过程可分为以下两个阶段。(1)吸入量不足。原因是吸油管路上的阻力过大或补油量不足。如泵的转速过大，油箱中液面过低，进油管漏气，滤油器堵塞等。2．中位时排油量不为零(1)吸入量不足。原因是吸油管路上的阻力过大或补油量不足。如泵的转速过大，油箱中液面过低，进油管漏气，滤油器堵塞等。6．液压泵过热(2)输出压力过高现在生产柱塞泵的厂家很多，进口件和国产件结构不尽相同，每一台泵都应严格按照其出厂使用说明书使用。在维修泵时，首先应该检查泵在系统中的安装、使用是否得当，便于及时查出损坏原因，消除隐患，保证系统正常工作。已修复的液压泵应通过一定的检测设备检测后才能。 大量的液压能损失转为热能，所以正确选择运动部件之间的间隙，油箱容积和冷却器，可以杜绝泵的过度发热和油温过高的现象，另外，回油过滤器堵塞造成回油背压过高，也会引起油温过高和泵体过热，(1)吸入量不足，原因是吸油管路上的阻力过大或补油量不足。
