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。
泵过度发热有两个原因:一是机械摩擦生热。柱塞泵由于运动表面处于干摩擦
或半干摩擦状态,运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低压腔,大量的液压能损失转为热能;长期负荷过大导致卸荷阀频繁开启,油缸或阀有内泄(阀内部磨损,缸密封不好);阀或管道有堵塞现象。所以正确选择运动部件之间的间隙、油箱容积和冷却器,可以杜绝泵的过度发热和油温过高的现象。另外,回油过滤器堵塞造成回油背压过高,也会引起油温过高和泵体过热。
液压泵转速高,排油压力高,工作环境恶劣,油液污染、油液选用不合规定或油液过少,都可造成泵损、泄漏。泵内泄漏可使其功率损失加大,磨损严重。油液中侵入空气后易于压缩,可造成泵干磨。液压泵内长时间的泄漏、干磨或压缩厉害, 必然发热,引起油液升温,造成系统发热。

喷油泵主要用在的汽车柴油机上,喷油泵总成通常是由喷油泵、调速器等部件安装在一起组成的一个整体。其中调速器是保障柴油机的低速运转和对高转速的限制,确保喷射量与转速之间保持一定关系的部件。而喷油泵则是柴油机重要的部件,被视为柴油发动机的“心脏”部件,它一旦出问题会使整个柴油机工作失常。A4VS0125DR30R-PPB13N00,
