汽动泵在核岛厂中的运维布置原则分析

Principle Analysis of Operation and Maintenance Arrangement of Pneumatic Pump in Nuclear Island Plant

辅助给水汽动泵在主给水系统不能使用,且全厂失电的情况下,向蒸汽发生器的二回路提供足够的给水流量,以保障机组的安全运行,但是汽动泵排出的乏汽会由于气流、温度等的影响而造成邻近房间消防喷淋,或者产生大量的凝结水。本论文正是基于此,对核电项目中汽动泵的运维布置进行经验总结,结合厂房布置与工艺布置的工作完成情况,对此项改进工作的可取之处和可借鉴之处进行布置原则分析,为其他项目问题的解决提供经验参考。

Auxiliary feed water vapor pump can provide sufficient feed water flow to the second circuit of steam generator to ensure the safe operation of the unit when the main feed water system can not be used and the whole plant is in power loss. However, Lack of steam due to the impact of airflow, temperature and other adjacent rooms caused by fire sprinkler, or produce a lot of condensate. Based on this, this paper summarizes the experience of the operation and maintenance of steam-driven pumps in nuclear power projects, combined with the completion of plant layout and process layout, the disposition of this improvement and the reference Analysis, provide solutions for other projects to provide an empirical reference.
