摘要
鉴于三峡ALSTOM机组补气阀运行几年后产生的问题,对补气阀工作原理进行了分析,并重新设计选型,改进了原补气阀的结构。实际运行表明:新补气阀运行稳定、可靠,满足机组安全运行的要求。
Seeing that some troubles in the air-admission valve of the Alstom hydro-generating unit in Three Gorges Power Plant have cropped up after put into operation several years later, according to the working principle analysis, the structure of the valve is reformed, the operating practice shows that the operation of the improved valve is more stable and reliable.
