Based on the present status of electricity consumption of water supply enterprises in shenyang , this paper analyzed the factors effeting on the electricity consumption , and put forward the outlines for energy saving 文章根据沈阳市给水系统电能消耗的情况，分析了影响电耗的因素，提出了节能的要点。
Intelligent application controller smartrelay applies to the automatic lighting factory automation or family management , access control , water supply systems , pump control or ventilation systems 智能型应用控制器smartrelay适用于工厂或家庭自动化中的自动照明管理存取控制给水系统泵机控制或通风系统。
Contamination of water supplies is usually due to poor sanitation close to water sources , sewage disposal into the sources themselves , leakage of sewage into distribution systems or contamination with industrial or farm waste 水源的污染通常是由于接近水源的地方卫生条件太差而造成的：污水排入水源，污水渗入给水系统或工农业污水造成污染。
This paper discusses on the necessity of making the vertical division for the high - rise buildings , probes into some key problems in the vertical division of the water - supply system , and discusses on the features of three kinds of water - supply modes 论述了高层建筑进行竖向分区的必要性,探讨了给水系统进行竖向分区的关键问题,并对3种给水方式的特点进行了论述。
Can install on the road at the pipe of any seat , preventing the medium go against the current , the boiler is to river system all last times , and namely his attended mode is using original pipeline both ends flanges can dive into the operating to the clamp 可在任何位置的管路上安装，防止介质逆流，锅炉给水系统上回，其连接方式是利用原有管道两端法兰对夹即可投入运行。
The method comprises of three components , namely , prediction model for hourly water of the entire network , model of water distribution system and optimization model . hourly water demand prediction of distribution system was mainly studied 本文介绍了城市给水系统优化调度技术的主要内容，并对优化调度的基础，如用水量预测模型，管网模型和优化调度模型进行了深入的研究。
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。
Main contents for optimal dispatch of pump stations in municipal water supply system were introduced , and delved the model of water prediction , analysis of water supply reliability , water distribution system and optimal dispatch 本文介绍了城市给水系统优化调度的主要内容，并对优化调度的关键内容如用水量预测模型、供水可靠性分析模型、管网的网络模型及优化调度模型进行了深入系统的研究。
By this way , however , the working pressure of the fire water system will be at higher level in case of the central stabilizing high pressure system and undesirable consequences related to the pressure - acceptance of the pipe and the joints shall come forth 而在集中稳高压给水系统中，这样确定的稳压泵扬程及设定压力值，往往使消防给水管网始终处于较高压力工况，因而使管网内水压与管道及其接口的承压能力这一对矛盾趋于突出。
