摘  要
传统的供水系统存在着占地面积大、建设费用高、管理维护复杂困难、供水质量低下等缺点和不足。为了解决这些问题,本文采用
 
 
  
  
  
  
  
  
  
  
  
  
  
  
 
 
 

 
控制技术和变频调速技术相结合的方法来研究恒压供水系统,该系统与现场液位传感器、压力传感器一起组成了两个独立的闭环控制子系统。设计好的系统每天24小时不间断按预先设定的水压恒定地向城市供水,保证了水厂的不间断生产。
通过该项目的研制和应用,不仅能够节约宝贵的水、电资源,降低了生产成本,减少设备维护,降低维修成本;而且提高了整个水厂的生产调度管理水平,减轻工人劳动强度,有效的提高了生产率。

ABSTRACT
Traditional water supply system has the shortages including occupying wide surface area、high expenses、management complex and difficult、water pollution again, and so on. In order to solve these problems, this paper combines  control technology and transducer technology to research constant pressure water supply system. Two independent sub-systems are irrespectively built with water place sensor and pressure sensor. The finished system can fulfill constantly supplying water to city day and night according to the water pressure given to assure the continuously produce.
With the research and use of this project, we can save large sum of precious water、electrical source, and decrease the produce price, reduce device management and lessen repair price. Moreover, this system also can improve the lever of produce and management, lighten the work’s strength, and increase the productivity.
 
 
Key Words: constant water supply system,  control transducer,
