德国力士乐A4VG系列高压柱塞泵技术参数和特点

Rexroth-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zui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；
◆zui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zui高转速：- 功耗为角功率的一半（例如当Vg man和PN/2时
2）高歇zui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。
