液压泵是液压系统的动力元件，其功用是给液压系统提供压力油，从能量转换角度讲，它将是原动机（如发动机）输出的机械能转换为便于输送的液体的压力能。液压马达则属于执行元件，它能将输入液体的压力能转换为输出轴转动的机械能，用来拖动负载做功。根据结构形式，液压泵与液压马达具体可分为齿轮式、叶片式、柱塞式等类型。
1.液压泵压力
液压泵工作压力是指泵（或马达）在实际工作时输出（或输入）油液的压力，由外负载决定。
额定压力是指在正常工作条件下，按试验标准规定能连续运转的高压力。其大小受寿命的限制，若**过额定压力工作，泵（或马达）的使用寿命将会比设计的寿命短。当工作压力大于额定压力时称**载。
2.转速
工作转速是指泵（或马达）在工作时的实际转动速度。
额定转速是指在额定压力下，能连续长时间正常运转的高转速。若泵**过额定转速工作将会造成吸油不足，产生振动和大的噪声，零件会遭受气蚀损伤，寿命降低。
低稳定转速是指马达正常运转所允许的低转速。在此转速下，马达不出现爬行现象。
3.排量、流量
排量是指泵（或马达）每转一周，由密封容腔几何尺寸变化而得的排出（或输入）液体的体积，常用单位是ml/r（毫升/转）。排量可以通过调节发生变化的成为变量泵（或变量马达），排量不能变化的成为定量泵（或定量马达）。
实际流量是指泵（或马达）工作时出口处（或进口处）的流量。由于泵本身存在内泄漏，其实际流量小于理论流量。由于马达本身也存在内泄漏，要实现*转速，为补偿泄漏量，其输入实际流量大于理论流量。
4.效率
容积效率，对液压泵是指其实际流量与理论流量的比值。对液压马达是指其理论流量与实际流量的比值。
机械效率，对液压泵是指其理论转矩与实际输入转矩的比值。对液压马达其实际输出的转矩为理论转矩克服摩擦力后的转矩，因此其机械效率为实际输出转矩与理论转矩的比值。
总效率是指泵（或马达）的输出功率与输入功率的比值。总效率等于容积效率与机械效率的乘积。
叶片泵依靠旋转叶轮对液体的作用把原动机的机械能传递给液体。由于离心泵的作用液体从叶轮进口流向出口的过程中，其速度能和压力能都得到增加，被叶轮排出的液体经过压出室，大部分速度能转换成压力能，然后沿排出管路输送出去，这时，叶轮进口处因液体的排出而形成真空或低压，吸水池中的液体在液面压力（大气压）的作用下，被压入叶轮的进口，于是，旋转着的叶轮就连续不断地吸入和排出液体。
柱塞泵是采用配油盘配油，缸体旋转，靠变量头变量的斜盘式轴向柱塞泵。该泵采用液压静力平衡的佳油膜厚度设计，使缸体与配油盘、滑靴与变量头之间处于纯液体摩擦下运转，具有结构简单、体积小、噪音低、效率高、寿命长和有自吸能力等优点。轴向柱塞泵具有多种变量形势满足用户的要求，它广泛适用于机床锻压、冶金、工程、矿山、船舶等机械及其他液压传动系统中

叶片泵的输人轴不能承受轴向力和径向力，因此安装联轴器时，不准用铁捶敲打装配，联轴器内孔采用二级间隙配合为宜，在键槽180°方向钻一个M6-M10mm的螺纹孔，用螵钉止住防止窜动。
