德国REXROTH柱塞 力士乐柱塞泵A10VSO28DRG现货 德国REXROTH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。
