柱塞泵柱塞往复运动总行程L是不变的，由凸轮的升程决定。柱塞每循环的供油量大小取决于供油行程,供油行程不受凸轮轴控制是可变的。供油开始时刻不随供油行程的变化而变化。转动柱塞可改变供油终了时刻，从而改变供油量。柱塞泵工作时，在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下，迫使柱塞作上、下往复运动，从而完成泵油任务，泵油过程可分为以下两个阶段。
进油过程
当凸轮的凸起部分转过去后，在弹簧力的作用下，柱塞向下运动，柱塞上部空间（称为泵油室）产生真空度，当柱塞上端面把柱塞套上的进油孔打开后，充满在油泵上体油道内的柴油经油孔进入泵油室，柱塞运动到下止点，进油结束
回油过程
柱塞向上供油，当上行到柱塞上的斜槽（停供边）与套筒上的回油孔相通时，泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通，油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油。此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行。此时便开始了下一个循环。
柱塞泵以一个柱塞为原理介绍，一个柱塞泵上有两个单向阀，并且方向相反，柱塞向一个方向运动时缸内出现负压，这时一个单向阀打开液体被吸入缸内，柱塞向另一个方向运动时，将液体压缩后另一个单向阀被打开，被吸入缸内的液体被排出。这种工作方式连续运动后就形成了连续供油 。

柱塞泵，是由电动机提供泵的动力，经鼓型齿联轴器带动减速机转动。由减速机减速带动曲轴旋转。通过曲柄连杆机构，将旋转运动转变为十字头和柱塞为往复运动。当柱塞向后死点移动时，泵容积腔逐步增大，泵腔内压力降低，当泵腔压力低于进口压力时，吸入阀在进口端压力作用下开启，液体被吸入；当柱塞向前死点移动时，泵腔内压力增大，此时吸入阀关闭，排出阀打开，液体被挤出液缸，达到了吸入和排出的目的。

滤油器的选用
一般粒径在10μm以下的污染物对泵的影响不太明显，而大于10μm、特别是在40μm以上时对泵的使用寿命就有明显影响。液压油中固体污染颗粒极易使泵内相对运动零件表面磨损加剧，为此需要安装滤油器降低油的污染程度。过滤精度要求：轴向柱塞泵10～15μm，叶片泵为25μm，齿轮泵为40μm。泵的污染磨损可以控制在允许范围之内。高精度滤油器使用日益广泛，可大大延长液压泵的使用寿命。

液压泵原理
是为液压传动提供加压液体的一种液压元件，是泵的一种。它的功能是把动力机(如电动机和内燃机等)的机械能转换成液体的压力能。图中为单柱塞泵的工作原理。凸轮由电动机带动旋转。当凸轮推动柱塞向上运动时，柱塞和缸体形成的密封体积减小，油液从密封体积中挤出，经单向阀排到需要的地方去。当凸轮旋转至曲线的下降部位时，弹簧迫使柱塞向下，形成一定真空度，油 箱中的油液在大气压力的作用下进入密封容积。凸 轮使柱塞不断地升降，密封容积周期性地减小和增 大，泵就不断吸油和排油。
