液压泵噪声过大故障排除要点：
1.吸油口或过滤器部分堵塞
2.吸油口连接处密封不严，有空气进入
3.吸油口高度太大，油箱液面低
4.泵与联轴器不同轴或松动
5.连接螺钉松动
6.液压油粘度太大，吸油口过滤器的通流能力小
7.定子内表面拉毛
8.定子吸油区内表面磨损
9.个别叶片运动不灵活或装反
解决方案：
1.除去污物，使吸油管路畅通
2.加强密封，紧固连接件
3.降低吸油口高度，向油箱加油
4.重新安装，使其同轴心，紧固连接件
5.适当拧紧
6.更换粘度适当的液压油，更换通流能力较大的过滤器
7.抛光定子内表面
8.将定子翻转装入
9.逐个检查、重装、对不灵活叶片重新装配
液压泵因为历史的液压泵根据中类型的不同有两种
一）指容积泵中的滑片泵。
二）指动力式泵的三泵（离心泵、混流泵、轴流泵）或其他的泵。
这类泵产品一般不会叫液压泵。但作为专著，液压泵几乎全部是指离心泵、混流泵、轴流泵等。
根据其每转的理论排量是固定值还是可变值，可以分为叶片式变量泵和叶片式定量泵。
工作原理编辑液压泵转子旋转时，叶片在离心力和压力油的作用下，尖部紧贴在定子内表面上。这样两个叶片与转子和定子内表面所构成的工作容积，先由小到大吸油后再由大到小排油，叶片旋转一周时，完成两次吸油与排油。
