鼓筒水位
Examples
- Soft - sensing model for drum level
锅炉汽包水位软测量模型研究 - Varations of drum level with starting up of boiler circulating pump in the forced circulation boiler
强制循环锅炉炉水循环泵启动对汽包水位的影响 - As per the contract , feedwater control system shall be in automatic mode at full range , and the requirement of drum level control index of feedwater control system is high
按照合同技术要求,一是给水控制系统必须全程投入自动;二是对给水控制指标(汽包水位)提出了较高的要求。 - 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。
