力士乐A4VSO变量柱塞泵A4VSO40DR/10R-PPB13N00
柱塞泵是由几个柱塞（一般为3个或6个）并列安装，用1根曲轴通过连杆滑块或由偏心轴直接推动柱塞做往复运动，实现吸、排液体的液压泵。它们也都采用阀式配流装置，而且大多为定量泵。煤矿液压支架系统中的乳化液泵一般都是卧式柱塞泵。
乳化液泵用于采煤工作面，为液压支架提供乳化液，工作原理靠曲轴的旋转带动活塞做往复运动，实现吸液和排液。
泵的泵油机构包括两套精密偶件：柱塞（plunger）+柱塞套(barrel)构成柱塞偶件(plunger and barrel assembly)（图5-11）、出油阀（delivery valve）和出油阀座(delivery valve seat)构成出油阀偶件(delivery valve assembly
柱塞和柱塞套是一对精密偶件，经配对研磨后不能互换，要求有高的精度和光洁度和好的耐磨性，其径向间隙为0.002～0.003mm

泵缸体安装铜套的三种方法：
（a）缸体加温热装或铜套低温冷冻挤压，过盈装配；
（b）采有乐泰胶粘着装配，这咱方法要求铜外套外径表面有沟槽；
（c）缸孔攻丝，铜套外径加工螺纹，涂乐泰胶后，旋入装配。[1]
熔烧结合方式的缸体与铜套，安装方法如下：
（a）采用研磨棒，手工或机械方法研磨修复缸孔；
（b）采用坐标镗床，重新镗缸体孔；
（c）采用铰刀修复缸体孔。[1]
采用“表面工程技术”，安装方法如下：
（a）电镀技术：在柱塞表面镀一层硬铬；
（b）电刷镀技术：在柱塞表面刷镀耐磨材料；
（c）热喷涂或电弧喷涂或电喷涂：喷涂高碳马氏体耐磨材料；
（d）激光熔敷：在柱塞表面熔敷高硬度耐磨合金粉末。
