摘要
针对某电厂600 MW直接空冷机组真空严密性不合格的现状,分析了真空严密性差的原因及危害,并解决了凝汽器真空系统的泄漏问题.通过真空严密性试验研究,采取有效的整改措施,使真空下降速度由294 Pa/min降低到31 Pa/min。
Aiming at the unqualified vacuum tightness of the 600 MW direct air-cooling generating units in a Power Co. , Ltd. , the causes for poor vacuum tightness were analyzed and the condenser vacuum system leak- age was solved. Through vacuum tightness testing after the rectification, the descent velocity of vacuum was dropped to 31Pa/min from previous 294Pa/min.
