300MW供热机组电动给水泵偶合器原理及倒转原因处理方法

The Coupler Theory of 300 MW Electrically Driven Feed Pump in Heat-supply Unit and its Inversion Processing Method

给水泵是热电厂的重要设备。在简单介绍了300 MW供热机组电动给水泵液力偶合器原理的基础上,从给水泵倒转的原因和采取的防范措施等方面进行了简要的阐述,分析了故障产生原因,提出了防止给水泵倒转的预防措施。

Driven feed pump is an important equipment in a heat and power plant.On the basis of briefly introducing the coupler theory of 300 MW electrically driven feed pump in heat-supply unit,the pump inversion reasons and some adopting measures were discussed,and then fault-causing reasons were analyzed and some precautionary measures to prevent pump inversion were proposed.
