丹尼逊柱塞泵
PV/PVT系列液压泵是适用于开式回路的轴向柱塞式变量液压泵,其设计的侧重终点在于工作的经济性。PVT系列是PV泵的带后驱动及侧面油口配置的派生系列。
PV/PVT系列柱塞泵变量形式有:压力补偿(恒压)变量、带遥控口的压力补偿变量、负载传感变量以及扭矩限 定(相当于恒功率)变量。连续工作压力可以达到280bar。DENISON柱塞泵已广泛用于高压及有变量要求的工业领域里,在工业领域里得到了很高的肯定。
丹尼逊柱塞泵功能特性
丹尼逊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。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PVH57QIC-RAF-2S-10-C25-31
