Vickers威格士柱塞泵按柱塞排列方向的不同,分为轴向柱塞泵和径向柱塞泵。在此,简要介绍轴向柱塞泵和回转式径向柱塞泵。Vickers威格士轴向柱塞泵。轴向柱塞泵由配流盘、缸体(转子)、柱塞和斜盘等主要零件组成。在配流盘上开有两个弧形沟槽,分别与泵的吸、压油口连通,形成吸油腔和压油腔。斜盘、配流盘均与泵体相固定,柱塞在弹簧的作用下以球形端头与斜盘接触。两个弧形沟槽彼此隔开,保持一定的密封性。斜盘相对于缸体的夹角为γ。原动机通过传动轴带动缸体旋转,柱塞就在柱塞孔内作轴向往复滑动。处于π~2π范围内的柱塞向外伸出,使其底部的密封容积增大,将油吸入;处于0~π范围内的柱塞向缸体内压入,使其底部的密封容积减小,把油压往系统中。
显然,泵的输油量决定于柱塞往复运动的行程长度,也就是决定于斜盘的倾角γ。如果γ角可以调整,就成为变量泵。γ角越大,输油量也就越大。
Vickers威格士径向柱塞泵。所示当转子旋转时,柱塞在离心力作用下,它的头部与定子内表面紧紧接触,由于转子与定子之间有一个偏心量е,所以柱塞在随转子转动的同时,又在柱塞孔内作径向往复滑动。当转子按图中箭头所示方向旋转时,上半周的柱塞皆往外滑动,柱塞孔内的密封容积增大,于是通过轴向孔吸油;下半周的柱塞皆往里滑动,柱塞孔内的密封容积减少,于是通过轴向孔压油。
vickers威格士柱塞泵的泵油机构包括两套精密偶件:柱塞(plunger)+柱塞套(barrel)构成柱塞偶件(plunger and barrel assembly)、出油阀(delivery valve)和出油阀座(delivery valve seat)构成出油阀偶件(delivery valve assembly 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 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。 柱塞头部斜槽的位置不同,改变供油量的方法也不同。 出油阀和出油阀座也是一对精密偶件,配对研磨后不能互换,其配合间隙为0.01mm 。 出油阀是一个单向阀,在弹簧压力作用下,阀上部圆锥面与阀座严密配合,其作用是在停供时,将高压油管与柱塞上端空腔隔绝,防止高压油管内的油倒流入喷油泵内。 出油阀的下部呈十字断面,既能导向,又能通过柴油。出油阀的锥面下有一个小的圆柱面,称为减压环带,其作用是在供油终了时,使高压油管内的油压迅速下降,避免喷孔处产生滴油现象。当环带落入阀座内时则使上方容积很快增大,压力迅速减小,停喷迅速。 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。
