控制精度高。变量行程短泵的变量是在变量柱塞和限位柱塞作用下,改变定子的偏心距实现的,而定于的zui大偏心距为 5—9mm(根据排量大小不同),变量行程很短。且变量机构设计为高压操纵,由控制阀进行控制。故该泵的响应速度快。径向结构设计克服了如轴向柱塞泵滑靴偏磨的问题。使其抗冲击能力大幅度提高。NACHI液压柱塞泵 液压柱塞泵靠气压供油的液压油箱,在每次启动机器后,必须等液压渍箱达到使用气压后,才能操作机械。直轴斜盘式柱塞泵分为压力供油型的自吸油型两种。压力供油型液压泵大都采用有气压的油箱,也有液压泵本身带有补油分泵向液压泵进油口提供压力油的。自吸油型液压泵的自吸油能力很强,无需外力供油。对于自吸油型柱塞泵,液压油箱内的油液不得低于油标下限,要保持足够数量的液压油。液压油的清洁度越高,液压泵的使用寿命越长。 结构形式

日本NACHI不二越PVS系列柱塞泵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。
