液压比例控制系统在液压支架用安全阀试验台上的应用

Application of Hydraulic Proportional Control System in Hydraulic Safety Valve Test Table

针对原液压支架用安全阀试验台流量调节过程繁琐、效率及检测精度低的问题,采用比例控制技术,进行闭环流量控制。改进了试验台的液压系统,实现了流量调节的自动化,提高了试验效率及检测精度。

There are problems existing in the original hydraulic safety valve test bench, including complicated flow controlling process and low accuracy and detection efficiency. To solve the problems, the proportional control technology was used to realize closed-loop flow control. The hydraulic system of the experiment platform was improved. The automation of flow regulation is realized, and the test efficiency and accuracy are improved.
