Design & Application of Variable Frequency Constant Pressure Technology in Water Supply System

The existed problem on traditional controlling way of city water supply system was analyzed,then the controlling principle of frequency conversion was elaborated.Finally,a designed practical example by frequency conversion technical was given on the water supply system.It was proved that frequency conversion can maintain constant pressure water,and it was a very ideal efficient measure for energy saving.Therefore design and transformation on water supply system had a broad market application prospect.
