叶片泵工作原理
叶片泵的定子内表面是一个圆形，转子与定子间有偏心距，在配油盘上只开有一个吸油窗口和一个压油窗口。当转子在电动机驱动下按图示箭头方向旋转时，叶片经定子下半部时，在离心力的作用下，从叶片槽中伸出，两叶片间的密封容积，实现吸油；叶片经定子上半部时，被定子内表面逐渐压入叶片槽内，密封容积减少，实现压油
叶片泵特性
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。
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
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。

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。
