摘要
Moog760先导阀是可控震源KZ-28的一个关键控制元件,但在震源运行过程中发现Moog760先导阀存在自激振荡现象。本文介绍了Moog760先导阀的结构原理及位置闭环控制系统,对Moog760先导阀自激振荡现象进行了理论分析,总结了导致这一故障的相关因素,并提出了相应的改进措施。
Moog760 pilot valve is a key control unit in KZ28 vibrator. During the field operation of vibrator, we found that Moog760 pilot valve has the self-excited oscillation. This article introduced the structure and principle of Moog760 pilot valve and its closed-loop position control system, analyzed the cause of self-excited oscillation, then proposed effective improvement measures.
