摘要

大坝发电厂 3号、4号汽轮机组投产以来高压调节汽门油动机的油缸温度一直偏高

经常发生油缸上部密封圈泄漏

压力油烧结积碳

油质变差

伺服阀频繁故障等问题

对此提出了改造方案

实施后取得显著效果。

Abstract

The temperature of servomotor's oil cylinder concerning the highpressure governing valve of a 300MW unit NO.3 in Daba Power Plant is somewhat higher from the begining of putting into operation right up to now

some problems

such as upper seal leakage of the oil cylinder

agglomerition and carbon deposition of the pressure oil

deterioration of the oil quality

as well as frequent failure of the servo valve etc.

have often occurred. For these reasons

a retrofitting scheme has been put forward

and after implementation of the said scheme

remarkable results having been obtained.
