两台水泵变频调速恒压供水电路的应用

Application of two pumps' constant pressure supply water circuit by frequency conversion to adjust speed

在中国大力开展节能减排的重要时期,结合当前供水的要求和特点,对两台泵变频调速恒压供水电路的构成、原理和控制线路的工作过程作了较为详细的研究,以推广变频调速恒压供水的应用。

In the important period of carrying out energy conservation and emission reduction vigorously in China, according to present request and characteristic of water- supply, in this paper, it is studied in detail such as the composition, the principle and working course of two pumps＇ constant pressure supply water circuit by frequency conversion to adjust speed, so as to extend the application of constrant pressure supply wa- ter circuit by frequency conversion.
