液压缸试验控制电路改进

Improvement on the Electrical Control Circuit of Hydraulic Cylinder Testing

本文介绍一种实现液压缸换向控制的电路，克服了原电路的一些缺点。与原电路相比，有结构体积小、控制灵活、可靠、稳定等特点，易于实现自动化控制。

This paper introduces a circuit that can control the kinetic orientation of cylinder. This circuit overcomes some de-fects of the original one, so the circuit is credible, stable, has small volume; and this circuit is apt to achieve automatic control.
