防止汽机甩负荷过程中给水泵汽蚀的条件和措施

The Conditions and Measures of Preventing Feed Water Pump's Cavitation when the Turbine's Load Rejects

根据汽机甩负荷造成给水泵汽蚀的原因及危害 ,从计算除氧器暂态过程中给水泵入口汽蚀余量的最大降落值入手 ,分析防止给水泵汽蚀的条件 ,提出预防措施。

According to the cause and the damage of the feed water pump cavitation resulting from the turbine's load rejection,this paper analyzes the condition about presenting cavitation by calculating the largest difference of the pump inlet's cavitation residue in the transient process of the deacrator and proposes the measures about presenting cavitation.
