力士乐比例换向阀4WRZE16W8
力士乐柱塞泵特点：
-用于液压开式回路的斜盘结构轴向柱塞变是泵
-流量正比于驱动转速和排量，关能通过调节斜盘倾角实现无级变量
-ISO标准的安装法兰
-法兰转接符合SAE米制
-有两个壳体泄油孔
-优良的吸入性能
-允许连续运行压力可达280Bar
-低噪声
-驱动轴能承受轴向及径向负载
-高的功率/重量比
-广范围的多种控制形式
-控制响应时间短
-采用通轴结构，可用于多回路系统
Rexroth柱塞泵具有一定的自吸能力，但自吸的高度不宜超过500mm，并且严禁在吸入管道上安装滤油器，吸入管道直径不小于推荐数值，另外自吸时一定要把泵先调至全偏角。   
在转速超过1500rpm时，宜采用供油，供油压力为0.7MPa左右。在开式系统中，供油泵的流量应为该泵的130%，在闭式系统中，供油泵的流量应为该泵的35%。
