基于REXROTH A4VG泵远程压力控制方案介绍

Introduction of Remote Pressure Control System Based on REXROTH A4VG Pump

REXROTH A4VG闭式泵是一款使用非常广泛的液压泵,其排量范围宽,控制方式多样及性能可靠使其成为闭式泵中的经典产品。该文将着重介绍其压力切断功能以及两种远程压力控制的工作原理,扩展了A4VG闭式泵的功能,并介绍了相关关键元件的选型以及设计时的注意点。此两种远程压力控制方案以应用于实际产品之中。

The REXROTH A4 VG pump is a widely used hydraulic pump, it is a classic product because of its wide range of displacement,many kinds of control methods and good performance in application. This article mainly introduces the working principle of Pressure Cut-off and two kinds of Remote Pressure Control systems for REXROTH A4 VG pump, as well as key components selection and some dos and donfs for designing. These two kinds of Remote Pressure Control systems have been applied in the real products.
