凝汽器单侧停运与对应抽真空隔离阀连锁关闭的必要性研究

Study on Chain Relationship between Condenser and Vacuum Isolation Valve

在凝汽器单侧隔离工况下,其对应的抽真空隔离阀应连锁关闭,且无论何种情况,均不建议打开此阀,否则会导致凝汽器内不凝结气体增多、抽真空泵性能下降、凝汽器性能恶化等后果。本文对比了单侧隔离工况和正常运行工况的异同,并从凝汽器漏气量、不凝结气体聚积趋势、抽真空泵性能、凝汽器性能等方面进行了分析。

In the condenser unilateral isolation conditions, the corresponding vacuum isolation valve should be shut down at the same time, and in any case, it is not recommended to open the valve, otherwise some consequences would occur, such as the increasing of non-condensable gas of the condenser, and degrading of vacuum pump performance and condenser performance. This paper makes a comparison of unilateral isolated condition and the normal operation condition, and analyzes the condenser leakage, non-condensing gas accumulation trends, vacuum pump performance, and the performance of the condenser.
