力士乐(Rexroth)柱塞泵A4VG系列


 Rexroth力士乐A4VG高压柱塞泵系列

-排量从28到250
-常用压力400bar(40Mpa)
-尖峰压力450bar(45Mpa)
力士乐A4VG特点:
 斜盘式轴向柱塞变量泵,用于闭式回路静液压传动
◆流量与驱动转速及排量成正比并可无级变量;
◆流量随斜盘摆角从零增加到其最大值;
◆使斜盘摆过中位可以平稳改变液流流动方向;
◆易与各种控制和调节系统匹配的多种变量方式;
◆泵在高压油侧配备两个溢流阀来保护静液压传动(泵和马达)免于超载;
◆高压溢流阀同时也具有补油阀的功能;
◆内置辅助泵用作补油泵和控制泵;
◆最高补油压力由一个内置补油溢流阀来限制;
◆全系列带有内置压力切断阀;
典型应用:
混凝土泵车、重型液压平板车、液压泵站
技术参数:
 数值表(理论值,未考虑ηmh和ηv;数值经过圆整)
 1)极限最高转速:- 功耗为角功率的一半(例如当Vg man和PN/2时
 2)高歇最高转速:- 在高速空载运行时
          - 在发动机超速期间:△p=70...150 bar 和 Vg max
          - 在反向尖峰负载时:△p<300 bar和 t < 5 秒。
