柱塞泵结构组成主要有偏心轮、柱塞、弹簧、缸体、两个单向阀。柱塞与缸体孔之间形成密闭容积。偏心轮旋转一转，柱塞上下往复运动一次，向下运动吸油，向上运动排油。泵每转一转排出的油液体积称为排量，排量只与泵的结构参数有关。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。柱塞泵是活塞或柱塞的往复运动方向与缸体中心轴平行的柱塞泵。轴向柱塞泵利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。由于柱塞和柱塞孔都是圆形零件，加工时可以达到很高的精度配合，因此容积效率高
供应A10VSO18DFR1/31R-PPA12N00工作介绍：
如果这个闭死容积的大小发生变化，在闭死容积由大变小时，其中的油液受到挤压，压力急剧升高，使轴承受到周期性的压力冲击，而且导致油液发热；在闭死容积由小变大时，又因无油液补充产生真空，引起气蚀和噪声
在液压系统中用来维持定压是溢流阀的主要用途。它常用于节流调速系统中，和流量控制阀配合使用，调节进入系统的流量，并保持系统的压力基本恒定。用于过载保护的溢流阀一般称为安全阀。
液压系统对溢流阀的性能要求
（1）定压精度高
（2）灵敏度要高
（3）工作要平稳且无振动和噪声
（4）当阀关闭时密封要好，泄漏要小。
