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。

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。
