摘要
对云浮发电厂3号机组给水泵切换操作时出现逆止门卡涩关不严所造成的机组停机事件进行描述,从给泵参数特性、流程以及故障过程等方面分析了B给泵逆止门倒转的原因;剖析高压给水泵倒转的风险,并对今后切换给水泵提出相应的防范措施。
This paper describes one unit closing-down incident caused by untight shut of check valve when operating water pump switching of No. 3 unit in Yunfu power plant. It analyzes reasons for check valve reversion of B water pump in as- pects of water pump parameter characteristics, technical process and fault process and risk of high pressure water pump re- version and proposes prevention measures for switching water pump.
