用可编程控制器实现无塔自动恒压供水

Using Programmable Make the Constant - Pressure Water Supply Controller into Reality in No Tower

从可编程器,变频调速器的技术特点入手,探讨一种利用可编程器和变频技术结合实现自动恒水供水的新方式.该系统尤其适用于城市大型供水系统.着重介绍了其原理、功能、结构.

From the teachnical feature of programmable and VFSR.the article approached the new way. Which is using programmable and VFSR combined to make the constant - pressure water supply into reality,This kind of system expecially suit large water supply system in the city. It mainly introduce the theory founction and instruction of the system.
