摘要
从压力控制供水系统的静特性出发，分析了变恒速为调速恒压供水节能的原理，给出了变频调速的系统图，提出了变频调速时的压额控制特性，使系统运行性能最好。
From a steady state characteristic of supply water system of pressure control,this paper analyzed the principle of variable frequency regulative speed for constant pressuresupply water. give this system diagram and proposed the VF control characteristic. The re-sults of the system ran are satisfactory.
