摘　　要：直流式循环冷却水系统多利用虹吸原理来降低循环水泵扬程,从而降低水泵功率以减少电耗,该原理在火电项目中运用较为成熟。针对核电项目厂坪标高较高,循环水量大等特点,提出了充分利用虹吸作用和溢流堰低位布置的两点设想,有利于减少循环水泵电耗,减轻以至消除排水口消能消泡的问题,使得循环水系统的运行更加经济和环保。Using bernoulli equation,this paper analyzed the water recycling system.Based on the characteristics of nuclear power plant,a new hydraulic calculation process was proposed in order to adopt the siphoning effect safely and effectively.It might save the recycling pump power consumption,relieve the problem of energy dissipation and bubble reduction,and bring considerable economy benefits.
