变频调速恒压供水系统的原理与实现

对城镇住宅电力驱动恒压供水的原理及几种实用化方案进行了深入的讨论，以变频器为主体的恒压供水系统对供水水泵实现全方位的保护。该系统不但能最大限度地节约水资源，而且能够节约电能、延长供水水泵的使用寿命，并在紧急情况下（消防、减灾）能够做到重点供水。最后，对几种实用化供水方案进行了详细的讨论。

The Principle and Realization of Constant Pressure Water Supply with Inverter

This paper discusses the principle and some practical schemes of electric drive residential constant pressure water supply in the urban residential area in details.The constant water supply system with the inverter as the main body can achieve the fully fledged protection of water supply pumps,which can not only save water resources and electric energy at the maximum,but also prolong the service life of water supply pumps,and in the case of emergency (fire fighting and reducing disusters),water supply can be guaranteed sufficiently. Also,this paper details some practical water supply schemes.
