叶片泵的分类 叶片泵又分为双作用叶片泵和单作用叶片泵。双作用叶片泵只能作定量泵用，单作用叶片泵可作变量泵用。 双作用叶片泵因转子旋转一周，叶片在转子叶片槽内滑动两次，完成两次吸油和压油而得名。 单作用叶片泵转子每转一周，吸、压油各一次，故称为单作用。
叶片泵的工作原理叶片泵转子旋转时，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。
叶片泵的注意事项叶片泵的管理要点除需防干转和过载、防吸入空气和吸入真空度过大外，还应注意： 1．泵转向改变，则其吸排方向也改变叶片泵都有规定的转向，不允许反。因为转 子叶槽有倾斜，叶片有倒角，叶片底部与排油腔通，配油盘上的节流槽和吸、排口是按既定转向设计。可逆转的叶片泵必须专门设计。 2．叶片泵装配 配油盘与定子用定位销正确定位，叶片、转子、配油盘都不得装反， 定子内表面吸入区部分易磨损，必要时可将其翻转安装，以使原吸入区变为排出区而继续使用。
型号 PV7 的液压泵是变量叶片泵。
主要由泵体、转子、叶片、定子环、压力控制器和调节螺栓组成。圆形的定子环夹持在小调节活塞和大调节活塞之间。此环的第三个接触点是高度调节螺栓。被驱动的转子在定子环内转动。转子槽内的叶片由于离心力的作用压在定子环上。
力士乐REXROTH叶片泵吸油和排油过程
用来传递油液的腔由叶片、转子、定子环和配油盘形成。
为了在投入使用时确保泵的运行功能，定子环由大调节活塞后面的弹簧压在其偏心位置 (排油位置)。
当转子转动时，油腔的容积增大，并且通过吸油通道吸油。当油腔达到大容积时，它脱离吸油侧。转子继续转动，此腔和压油侧接通，并使其容积减小，通过压油通道压油到系统。
类型 PV7...A 液压泵是直动式叶片泵，其排量体积可调。
基本上由壳体，盖板，转子，叶片，定子环，压缩弹簧，调整螺钉和控制板组成。为限制大流量，该泵配有调节螺钉。驱动转子在定子环中旋转。转子中导入的叶片在离心力的作用下贴紧定子环的内跑合面。
吸油和排油过程
运输流体所需的腔室由叶片，转子，定子环，控制板和盖板组成。
转子旋转时室体积增加，腔室通过吸油通道填充流体。达到大室体积后，腔室从吸油侧分离。
随着转子继续旋转，高压流体侧的连接打开，腔室缩小并迫使流体通过压力油口进入系统。
压力控制
定子环由弹簧固定在其初始的偏心位置。系统中所需的大工作压力是在调节螺钉处通过弹簧设定。增大的压力是由于对抗弹簧力的工作阻力作用于定子
环内跑合面的压力侧而产生的。
达到相关压力（由设定的弹簧力决定）后，定子环朝零位置的方向移出其偏心位置。流量自我调节至当时所需的值。当达到
弹簧处设置的大设定压力时，泵会将流量调回至几乎为零。工作压力得到保持，且仅更换泄露流体。流体的损失和加热从而降至低水平。

液压泵是液压系统的动力元件，是靠发动机或电动机驱动，从液压油箱中吸入油液，形成压力油排出，送到执行元件的一种元件。液压泵按结构分为齿轮泵、柱塞泵、叶片泵和螺杆泵
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（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。
常用液压泵的种类：
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。
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。
液压泵特点
铝合金制造、强度高、耐腐蚀、重量轻、适合各种环境下作业。
双速特性减少了打压次数，在低压室快速处于负载用功状态，立刻转换成高压，缩短每次作业周期。
配有压力调节阀，可调节控制及设定工作压力。
液压系统的组成及其作用
一个完整的液压系统由五个部分组成，即动力元件、执行元件、控制元件、辅助元件(附件)和液压油。
动力元件的作用是将原动机的机械能转换成液体的压力能，指液压系统中的油泵，它向整个液压系统提供动力。液压泵的结构形式一般有齿轮泵、叶片泵和柱塞泵。
执行元件(如液压缸和液压马达)的作用是将液体的压力能转换为机械能，驱动负载作直线往复运动或回转运动。
控制元件(即各种液压阀)在液压系统中控制和调节液体的压力、流量和方向。根据控制功能的不同，液压阀可分为压力控制阀、流量控制阀和方向控制阀。压力控制阀又分为益流阀(安全阀)、诚压阀、顺序阀、压力继电器等;流量控制阀包括节流阀、调整阀、分流集流阀等，方向控制阀包括单向阀、液控单向阀、梭阀、换向阀等。根据控制方式不同，液压阀可分为开关式控制阀、定值控制阀和比例控制阀。
辅助元件包括油箱、滤油器、油管及管接头、密封圈、快换接头、高压球阀、胶管总成、测压接头、压力表、油位油温计等。
液压油是液压系统中传递能量的工作介质，有各种矿物油、乳化液和合成型液压油等几大类。

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，若超过额定压力工作，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超载。
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。若泵超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，要实现指定转速，为补偿泄漏量，其输入实际流量必须大于理论流量。
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。
