| 摘 要： | 火电机组等级检修后真空系统查漏是发现系统漏点,保证机组启动后真空严密性的一项重要工作.与纯凝式机组相比,空冷机组真空系统的空间更为庞大,不宜采用整体灌水的方法进行查漏.借鉴国内部分电厂采用了压缩空气查漏的办法,经过多次现场工作的摸索和实践,总结出一套结合灌水查漏和压缩空气加压相结合的查漏办法,提高了漏点判断的准确性,实...

| Abstract: | The overhaul of the machine is a key job which can discover the leak and make sure the vacuum tight of the machine after it running.Compare with the pure condenser unit,the air cold machine has a bigger vacuum system.It is about 36 meters high and it's Internal space about 12 cubic meters.It is no proper to check the machine with water to discover the leak,some power of domestic check the leak by condense the air of the machine,which set a good example for other unit.After hard explore and practice,company ... |
