一、液压泵装配不良导致液压泵异常发热：

①液压泵中的间隙在选配时不合适(例如柱塞与缸体、叶片与转子槽、定子与转子、齿轮与侧板等配合间隙过小等都会造成滑动部位过热烧伤)。

②液压泵的装配质量差，传动部分同轴度没有达到技术要求，在液压泵运转的时候有别劲的现象怠敞糙缎孬等茬劝长滑出现。

③液压泵中轴承的质量差或是在装配的时候被打坏，或是在液压泵安装的时候没有清洗干净，造成液压泵在运转时别劲。

④经过轴承的润滑油排油口不畅通:由于回油口螺塞未打开(未接管子)，或是在安装的时候通油道没有清洗干净，导致有脏物绪住油口，还有可能是由于在安装时回油管弯头太多或有压扁的现象，导致排油口不通畅。

二、液压泵油液质量差所导致液压泵异常发热：

①在液压泵中使用的油液黏度与温度的特性差，在使用过程中黏度变化差很大。

②使用的液压油中含有大量水分，造成液压油的润滑不良，导致液压泵异常发热。

③长期没有更换液压泵中的油液，或是使用的液压油已被污染严重，导致液压泵发热。

三、液压泵管路故障导致液压泵发热：

①连接液压泵的泄油管被压扁或被堵死，导致无法泄油而使油泵发热。

②液压泵的排油管管径太细，不能使液压泵顺畅的排出油液，达不要排油要求。

③液压泵的吸油管径小，使得液压泵的吸油阻力大，无法正常吸油，导致油泵发热。
