深井直接供水水泵变频调速控制系统研究

study on the frequency control system of motor speeds for the water pump in deep well

在对深井直接供水系统压力变化分析基础上，论证该系统水泵变频调速供水原理。

This paper analyses the change law of the water pressure in water supply system from deep well and demonstrates the principle of the water supply by using frequency control of motor speed. The formula for the profit analysis of the system is given in this paper.
