齿轮泵：体积较小，结构较简单，对油的清洁度要求不严，价格较便宜；但泵轴受不平衡力，磨损严重，泄漏较大。

叶片泵:分为双作用叶片泵和单作用叶片泵。这种泵流量均匀、运转平稳、噪音小、作压力和容积效率比齿轮泵高、结构比齿轮泵复杂。

柱塞泵:容积效率高、泄漏小、可在高压下工作、大多用於大功率液压系统;但结构复杂，材料和加工精度要求高、价格贵、对油的清洁度要求高。

一般在齿轮泵和叶片泵不能满足要求时才用柱塞泵。还有一些其他形式的液压泵，如螺杆泵等，但应用不如上述3种普遍。   

      液压泵主要有齿轮泵、叶片泵、柱塞泵等，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。在机器运行过程中，齿轮泵常见的故障有：噪声严重及压动；输油量不足；液压泵不正常或有咬死现象。
