液压泵为液压传动提供加压液体的一种液压元件，是泵的一种。它的功能是把动力机（如电动机和内燃机等）的机械能转换成液体的压力能。影响液压泵的使用寿命因素很多，除了泵自身设计、制造因素外和一些与泵使用相关元件（如联轴器、滤油器等）的选用、试车运行过程中的操作等也有关系。

液压泵的工作原理是运动带来泵腔容积的变化，从而压缩流体使流体具有压力能。

必须具备的条件就是泵腔有密封容积变化。 

液压泵的种类：

1、按流量是否可调节可分为：变量泵和定量泵。输出流量可以根据需要来调节的称为变量泵，流量不能调节的称为定量泵。

2、按液压系统中常用的泵结构分为：齿轮泵、叶片泵和柱塞泵3种。

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。

油泵可以分为容积式和非容积室（蜗轮式）两种。非容积式有离心泵、轴流泵等，利用高速旋转的叶轮使进口产生真空吸入液体，并在出口连续输出压力液体。这种泵进口与出口相通，效率随液体粘度增加而降低，并且输出液体量随出口压力升高而显著减少。

容积式泵是通过一个封闭的空间容积的变化来实现吸油和压油的。当这个封闭容积由小变大时进行吸油，由大变小时进行压油。典型的为力士乐柱塞泵，柱塞从缸孔中拉出时吸油，压进时压油。这种泵进口与出口是被隔开的，效率取决于隔开吸压油腔的各对运动零件间的结构工艺间隙及油液的粘度等。粘度越率越高，输油量几乎保持不变（因效率略有影响，另外压力升高至18MPa，油液会被压缩1%）。

泵工作前，先将泵内充满液体，然后启动离心泵，叶轮快速转动，叶轮的叶片驱使液体转动，液体转动时依靠惯性向叶轮外缘流去，同时叶轮从吸入室吸进液体，在这一过程中，叶轮中的液体绕流叶片，在绕流运动中液体作用一升力于叶片，反过来叶片以一个与此升力大小相等、方向相反的力作用于液体，这个力对液体做功，使液体得到能量而流出叶轮，这时液体的动能与压能均增大
