一次射水抽气系统定期切换后真空异常下降的原因分析及处理

Cause Analysis and Treatment of Abnormal Vacuum Drop after Periodic Switching of Primary Water Jet Air Extracting System

针对某电厂定期切换射水泵的工作过程中,凝汽器真空持续下降、调整无效的异常情况展开分析,找到处理方法,解决了射水抽气系统不能正常投运的问题,同时提出了改善优化思路。

In view of the abnormal situation of condenser vacuum continuous drop and ineffective adjustment during the regular switching of water jet pump in a power plant,a treatment method was found to solve the problem that the water jet air extraction system could not be put into operation normally,at the same time improvement and optimization ideas were put forward.
