广州机床研究所于一九七四年开始,进行电液比例控制元件的开发研究工作,已经研制了压力阀类、流量阀类、换向阀类及复合阀类四大类约20多个品种规格,其技术性能已能满足很多行业的要求。为了更广泛地推广上述科研成果,除了对元件的性能应作进一步改进及扩大品种规格外,最主要的是在控制系统方面还要作进一步的研究及探索,以便更多的设备在更新换代的时候,能够采用这个新的技术。本文仅就作者所接触到的典型系统,作一些概括的、粗浅的
Guangzhou Machine Tool Research Institute started in 1974, the development of electro-hydraulic proportional control components, has developed a pressure valve, flow valve, valve and valve complex four categories of about 20 varieties Specifications, its technical performance has been able to meet the requirements of many industries. In order to promote the above scientific research achievements more extensively, in addition to further improvement on component performance and expansion of variety specifications, the most important thing is to further study and explore the control system so that more equipment can be replaced When, can adopt this new technology. This article only makes some generalizations and superficialities about the typical system that the author touches
