对漏空气点分布规律、检漏方法和消除漏点措施进行了讨论。通过采用现代化的检漏堵漏等技术
总结出提高该型机组的真空严密性的一些方法和经验。消漏措施实施后
2号机组真空严密性由0.696 kPa/min提高至0.098 kPa/min。
Abstract
The tightness of vacuum system for 300 MW unit no.2 in Guo'an Electric Power Co Ltd has been tested
the distribution regularity of air leakage points
the leakage detecting method and the leakage eliminating measures being discussed.Through adopting modern leakage-detecting technology etc.
some methods and experiences for enhancing the tightness of vacuum for unit of its type have been summarized up.After implementation of said leakage-eliminating measures
the tightness of vacuum for unit no.2 has been enhanced from 0.696 kPa/min to 0.096 kPa/min.
