经典闭式回路原理图[0]

Posted on 2023年11月14日 by

闭式回路一般用于大功率(>37KW)和慢动作(0.1cycle/s)的环境。因为其主回路没有节流阀而节能。

此部分的原理图不包括适用于EHA的回路图。(EHA相关的一些论文资料整理),因此此部分主要是传统的闭式回路及其原理。

  • 教材原理图

  • A4VSG系列的厂商推荐闭式原理图

上图中:

1)A4VSG泵的样本

2)力士乐A4VSO和A4VSG EO控制用放大板原理,其他泵的控制方式HM, HS, HS4, EO

3)位置传感器见LVDT的原理

4)冲洗阀SDVB16

5)比例阀4WRA6V30-2X/G24N9K4/V-589(力士乐)/DLHZO-TE040L3(ATOS),在此控制下,泵的相应时间为0.22s

6)梭阀

7)短路阀Z4WE6E68-2X/AG24NZ4

8)补油泵

补充说明:宁波恒力A4VSO和A4VSG泵的介绍
