给水调节阀 meaning in English
feed water regulating valve
feed-control valve
feed-regulating valve
Examples
- Both units ( 2x300mw ) of one power plant in india , designed and constructed by china , employ feedwater system composed of three 50 % capacity motor driven feedwater pumps , one low load feedwater control valve and one main motor - operated - valve
由我国承建的印度某电厂两台300mw发电机组,其给水系统设三台电动调速给水泵、一个低负荷给水调节阀(用于低负荷水位控制)和一个电动主闸阀。 - During unit startup and load is lower than 15 % , drum level is controlled by feedwater control valve , feedwater pump remains at minimum safety speed ; when load is between 15 % and 25 % , feedwater control valve is closing at fixed speed determined by function module , main motor - operated - valve is opened automatically , control mode of drum level is transferred to feedwater pump automatically and bumplessly ; when load is between 25 % and 50 % , control valve is closed fully , and main motor - operated - valve is open fully , drum level is controlled by one pump ; when load is more than 50 % , first pump is kept in operation , second pump is putting into operation automatically and
在机组启动、冲转及机组并网至15 %负荷阶段,给水泵维持在最低安全转速下运行,汽包水位由低负荷给水调节阀自动控制; 15 %至25 %负荷阶段,给水调节阀由函数模块按照一定的速率自动平滑关闭,主给水电动门自动打开,汽包水位控制方式自动无扰切换为给水泵自动控制;负荷在25 %至50 %阶段时,给水调节阀已完全关闭,主给水电动门已完全打开,水位控制已全由单台给水泵承担;负荷大于50 %后,在第一台给水泵运行的同时,第二台给水泵自动无扰投入。
