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。

在应用的各种液压设备中，液压泵是关键性的元件，它们的性能和寿命在很大程度上决定着整个液压系统的工作能力，随着时代的发展和技术的进步，液压泵性能越 来越完善，在各种工业设备、行走机构以及船舶和飞机上都得到了广泛应用。因此对于叶片泵相关知识的学习和认识十分必要，特别是对于从事液压相关方面工作的人更显得尤为重要。
液压泵作为现代液压设备中的主要动力元件，它决定着整个液压系统的工 作能力。在液压系统中，液压泵的功能主要是将电动机及内燃机等原动机的机械能转换 成液体的压力能，向系统提供压力油并驱动系统工作。
在液压传动与控制中使用最多 的液压泵主要有齿轮式、叶片式和柱塞式三大类型。其中叶片泵是在近代液压技术发展早期实用的一种液压泵。
叶片泵与齿轮式、柱塞式相比，叶片泵具有尺寸小、重 量轻、流量均匀、噪声低等突出优点。在各类液压泵中，叶片泵输出单位液压功率所需 重量几乎是最轻的，加之结构简单，价格比柱塞泵低，可以和齿轮泵竞争。
定量叶片泵为双作用叶片泵，是现今已经发展成熟，并在工业领域得到应用的一种液压泵，双作用叶片泵是一般不能变量的，且径向力平衡的,因此工作情况较其它泵良好，被应用于液压系统领域，成为液压工业上不可或缺的关键性元件。
液压叶片泵的发展史 液压叶片泵的发展史即为叶片泵从诞生到发展的历史，作为液压系统的关键性动力元件，它随着液压系统的诞生而诞生，随着液压技术的发展而发展，并不断完善以适应新的液压系统的性能要求。
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最易磨损，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。
单作用叶片泵的工作原理
单作用叶片泵构造 基本结构：定子、转子、叶片、配油盘（吸、排口）、壳体（吸、排接管）、前、后 盖板。 定子型线是圆，转子也是园，二者存在偏心距。 片间工作空间：叶片、定子内表面、转子外表面、配油盘或盖板围成。
