在水轮机调速器电液随动系统中,电液伺服阀是个关键元件,我们开发了 DF型电液伺服阀,并投入电站试用,经不断完善,已趋成熟,陆续为产品配套。本文着重就 DF 型电液伺服阀研制过程中的一些主要技术问题和解决方法作较详细介绍。
In electrohydraulic servo system of hydraulic turbine governor, electro-hydraulic servo valve is a key component. We developed DF electro-hydraulic servo valve and put it into trial use in power station. After continuous improvement, it has matured gradually to support the products. This article focuses on the DF-type electro-hydraulic servo valve development process some of the major technical issues and solutions for more detail.
