摘要
采用REXA执行器取代电液伺服阀,对华能岳阳发电有限责任公司2号机组、GEC ALSTHOM 362.5MW汽轮机、抗燃油DEH系统进行了改造。彻底解决了电液转换装置易受油质污染的缺陷,消除了影响机组安全运行的隐患,提高了DEH系统运行的稳定性、可靠性,改造的成功为抗燃油DEH系统的设计、改造提供了新的途径。
Replacing servo valve by REXA actuator, the No. 2 unit DEH system of Huaneng Yueyang Power Plant is retrofitted successfully. Because of having no servo valve, the DEH system can run normally without being concern about the problem of dirty oil of system, and the stability and reliability of DEII system can be improved. Practice shows a new way for design or retrofit of DEH in hydraulic system.
