摘要
液压系统在高压下的保压控制很重要，本文介绍了采用光导卸荷控制保压，自动补压系统的工作原理及特点，此系统克服了溢流阀保压控制使油温升高的弊病。
The pressure maintaining of hydraulic system in high pressure condition is very important.The working principle and characteristics of preceeror relief method to control pressure maintaining and automatic pressure compensation system are introduced in this article. This system has overcome the disadvantage of oil temperature rise resulted in overflow valve Pressure maintaining.
