VICKERS威格士PVH柱塞泵/东莞威格士

威格士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三个阶段。
1、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。
2、供油过程
当凸轮轴转到凸轮的凸起部分顶起滚轮体时,柱塞弹簧被压缩,柱塞向上运动,燃油受压,一部分燃油经油孔流回喷油泵上体油腔。当柱塞顶面遮住套筒上进油孔的上缘时,由于柱塞和套筒的配合间隙很小(0.0015-0.0025mm)使柱塞顶部的泵油室成为一个密封油腔,柱塞继续上升,泵油室内的油压迅速升高,泵油压力>出油阀弹簧力+高压油管剩余压力时,推开出油阀,高压柴油经出油阀进入高压油管,通过喷油器喷入燃烧室。
3、回油过程
威格士柱塞向上供油,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。
威格士柱塞泵是往复泵的一种,属于体积泵,其柱塞靠泵轴的偏心转动驱动,往复运动,其吸入和排出阀都是单向阀。当柱塞外拉时,工作室内压力降低,出口阀关闭,低于进口压力时,进口阀打开,液体进入;柱塞内推时,工作室压力升高,进口阀关闭,高于出口压力时,出口阀打开,液体排出。带滑靴结构的轴向柱塞泵是目前使用zui广泛的轴向柱塞泵,安放在缸体中的柱塞通过滑靴与斜盘相接触,当传动轴带动缸体旋转时,斜盘将柱塞从缸体中拉出或推回,完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角,通过调节斜盘的倾角可改变泵的排量。
