1、液压泵故障
液压泵主要有齿轮泵、叶片泵等，下面以齿轮泵为例介绍故障及其诊断。齿轮泵最常见的故障是泵体与齿轮的磨损、泵体的裂纹和机械损伤。出现以上情况一般必须大修或更换零件。
在机器运行过程中，齿轮泵常见的故障有：噪声严重及压力波动；输油量不足：液压泵不正常或有咬死现象。
(1)噪声严重及压力波动可能原因及排除方法
1)泵的过滤器被污物阻塞不能起滤油作用：用干净的清洗油将过滤器去除污物。
2)油位不足，吸油位置太高，吸油管露出油面：加油到油标位，降低吸油位置。
3)泵体与泵盖的两侧没有加纸垫；泵体与泵盖不垂直密封：旋转时吸入空气：泵体与泵盖间加入纸垫；泵体用金刚砂在平板上研磨，使泵体与泵盖垂直度误差不超过0.005mm，紧固泵体与泵盖的联结，不得有泄漏现象。
4)泵的主动轴与电动机联轴器不同心，有扭曲磨擦：调整泵与电动机联轴器的同心度，使其误差不超过0.2mm。
5)泵齿轮的啮合精度不够：对研齿轮达到齿轮啮合精度。
6)泵轴的油封骨架脱落，泵体不密封：更换合格泵轴油封。
(2)输油不足的可能原因及排除方法
1)轴向间隙与径向间隙过大：由于齿轮泵的齿轮两侧端面在旋转过程中与轴承座圈产生相对运动会造成磨损，轴向间隙和径向间隙过大时必须更换零件。
2)泵体裂纹与气孔泄漏现象：泵体出现裂纹时需要更换泵体，泵体与泵盖间加入纸垫，紧固各联接处螺钉。
3)油液黏度太高或油温过高：用20#机械油选用适合的温度，一般20#全损耗系统用油适用10~50ºC的温度工作，如果三班工作，应装冷却装置。
4)电动机反转：纠正电动机旋转方向。
5)过滤器有污物，管道不畅通：清除污物，更换油液，保持油液清洁。
6)压力阀失灵：修理或更换压力阀。
(3)液压泵运转不正常或有咬死现象的可能原因及排除方法
