特性
1.可在压力设定下具有自动高速流量及补偿功能，比定量叶片泵功率损耗少，发热低，是一种节省能源的率叶片泵，为系统设计工程师在率的回路中佳选择。
2.运转平衡安静，特别适合机床和室内的要求。
3.内含压力调整机构，系统可以不要调压阀并且适用直接式电动机，装配容易。
4.备有多种不同压力及流量范围，可供选择。
叶片泵使用要点
1.为了使叶片泵可靠地吸油，其转速在500～1500r/min的范围，转速太低时，叶片不能紧压定子的内表面和吸油；转速太高则造成泵的“吸空”现象，泵的工作不正常。油的粘度要选用适当，粘度太大，吸油阻力；油液过稀，间隙影响，真空度不够，会对吸油造成不良影响。
2.叶片泵对油中的污物很敏感，工作可靠性较差，油液不清会使叶片卡死，因此注意油液良好过滤和环境清洁。
3.因泵的叶片有安装倾角，故转子只允许单向旋转，不应反向使用，否则会使叶片折断。
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。
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。的压力是由于对抗弹簧力的工作阻力作用于定子

泵的吸油滤油器，应采用泵流量的两倍以上，允许吸人真空度不大于0.013Mpa。在系统中的回油管路上，应设置过滤精度不大于20~30μm的回油滤油器，当新安装的系统工作10~20h后，可将回油滤油器拆开，取出滤芯，其内部有氧化皮、电焊渣、铁屑、砂粒和橡胶碎块等杂质，这些杂物是安装系统时未清理净的或液压件内部存留的，经压力的振动和流体的冲击而集中在回油滤油器内，若无回油滤油器时，则全部集中在油箱下部。
