REXROTH力士乐叶片泵
叶片泵
（1）单作用叶片泵的工作原理 单作用叶片泵的工作原理。转子外表面和定子内表面都是圆柱面。转子的中心与定子的中心保持一个偏心距e。在配油盘上开有吸油窗口和压油窗口，当转子如图示方向转动时，下部两相邻叶片、定子、转子及配油盘所组成的密闭容积，油液通过吸油窗口吸入；而上部两相邻叶片、定子、转子及配油盘所组成的密闭容积减小，油液由压油窗口压送到压油管中去。改变偏心距e的大小，可以改变泵的。当 e=O即转子中心与定子中心重合时，泵的为零。转子转一周，吸、压油各一次。由于径向液压力只作用在转子表面的半周上，转子受不平衡的径向液压力，故轴承将承受较大的负载，其寿命较短，不宜用于高压。
（2）双作用叶片泵的工作原理 双作用叶片泵的工作原理，泵有两个吸油窗口和两个压油窗口。转子转一周，泵吸、压油各两次。由于转子承受的径向液压力是平衡的，轴承受的力很小，故寿命长，适用于中高压系统。
叶片泵的优点是：运转平稳、压力脉动小，噪声小、结构紧凑、尺寸小、大。其缺点是：对油液要求高，如油液中有杂质，则叶片容易卡死；与齿轮泵相比结构较复杂。它广泛应用于机械制造中的机床，自动线等中、低压液压系统中。该泵有两种结构形式：一种是单作用叶片泵，另一种是双作用叶片泵
叶片泵的脚架安装式
泵体用螺钉安装固定在的脚架上，而脚架再用螺栓固定在机器设备的底板上。采用这种安装方式时，泵轴与原电动机之间通过弹性联轴器或其他传动构件连接，对安装精度的要求可以降低，但占地尺寸较大。
叶片泵的法兰安装式
利用泵体上的法兰端面和止口圆周定位，而泵的轴端则插入机器设备传动轴的轴芯孔内，用螺钉将泵体上的法兰直接安装固定在机器设备的箱体上。这种安装方式结构紧凑，占用空间小，但对机器设备上止口圆周与主轴、轴芯孔的同心度，以及法兰端面的轴线的垂直度等加工精度要求高，以保证安装后泵轴与机器设备传动轴的同心，否则会影响泵的正常工作。
