叶片泵吸油和排油过程
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。
叶片泵安装详解 
1、油泵支架座要牢固，刚性好，并能充分吸收振动。
2、泵和电机轴同轴度应控制在0.1mm以内，尽可能采用柔性联轴节，以避免泵轴承受弯矩及轴向载荷。
3、油泵的吸入管道通径应不小于泵通径，吸油滤油器通流量应不低于油泵油量的两倍。
4、泵吸吸入压力的数值请参照下表所示(对于某些排量的泵，低吸入压力受转速限制)。如泵安装**油箱时，吸距油液液面高度应小于1米，使用脂或含水液压液时应小于o．8米。
5、当泵的工作转速《1200r/min时，安装时，应将泵的吸向上，以便启动时易于吸油。
6、注意进油口处连接法兰、接头以及整个吸油管道必须严格密封，防止漏气，否则会引起噪声并使油箱内产生大量泡沫，降低泵的寿命。
7、油箱应设有隔板，用来分隔回油带来的气泡与脏物。回油管应伸到油面以下(不得直接和泵的连接)，防止回油飞溅引起气泡。
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。

液压油箱在液压系统中的主要作用为储油、散热、分离油中所含空气及泡沫。选用油箱先要考虑其容
量，一般移动式设备取泵大流量的2～，固定式设备取3～；其次考虑油箱油位，当系统全部液压油缸伸出后油箱油面不得低于低油位，当油缸回缩以后油面不得**高油位

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。
