威格士VICKERS柱塞泵

威格士VICKERS柱塞泵

威格士油泵结构形式
1）威格士柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点，被广泛应用于高压、大流量和流量需要调节的场合，诸如液压机、工程机械和船舶中。
2）威格士柱塞和柱塞套是一对精密偶件，经配对研磨后不能互换，要求有高的精度和光洁度和好的耐磨性，其径向间隙为0.002～0.003mm
3）威格士柱塞头部圆柱面上切有斜槽，并通过径向孔、轴向孔与顶部相通，其目的是改变循环供油量；柱塞套上制有进、回油孔，均与泵上体内低压油腔相通，柱塞套装入泵上体后，应用定位螺钉定位。
威格士柱塞头部斜槽的位置不同，改变供油量的方法也不同。
编辑本段威格士油泵回油过程
① 柱塞往复运动总行程L是不变的，由凸轮的升程决定。
② 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。
③ 供油开始时刻不随供油行程的变化而变化。
④ 转动柱塞可改变供油终了时刻，从而改变供油量
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。
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。
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。
