Proper consideration of both items will help the customer determine suitable sump pit dimensions and level control elevations 正确考虑这两个问题将有助于用户确定适当的污水坑直径和水位控制高度。
Nowdays , flood reason limited water level is staticslly controlled in most reservoirs , which wastes plentiful flood resources 目前，水库多数采用静态汛期限制水位控制方法，产生了洪水资源大量浪费的现象。
This paper uses the boiler water level system as the controlled object , studies and realizes the web - based remote control system 本文以工业锅炉水位控制系统为被控对象，研究并实现了基于web的远程控制系统。
The third part : a reservoir operation system is built up . it includes water level control model , discharge control model and generation model 第三部分，研究和建立了一个集发电调度模型、水位控制模型和流量控制模型于一体的水库单库调度模型集成系统。
Then a fuzzy control system is designed on the basis of the characteristic of boiler , though the dynamic quality is improved , there is static error 在此基础上结合锅炉对象的特点设计了水位控制的模糊控制系统，虽然系统动态品质得到明显改善，然而系统存在稳态误差。
The simulation results prove that the control system has perfect decouple and self - learning control performance for multi - variable strong - coupled time - varying deaerator water level control system 仿真结果表明，该控制系统对多变量强耦合的除氧器水位控制对象具有良好的解耦性能和自学习控制特性。
The main contributions are as follows : 1 . the usual instrument faults existing in boiler water level control system are intensively investigated and described mathematically 具体包括以下几个方面： （ 1 ）深入研究了汽包水位的串级三冲量控制系统，分析了汽包水位控制系统中常见的故障，并对这些故障进行了模型化研究。
Easy for operation with cpu control system , there auto - fill water into water tank / heater system and water level auto - controlled system in the machine so that it can be operation in order , keep right temperature with auto - controlled system during the machine operation Cpu电脑板控制系统,操作简便,水箱加热器自动注水,自动水位控制,确保运转正常,自动温控装置保持温度恒定
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。
