多参数变频恒压供水系统的研制

The Application of Transducer and PLC in Frequency Conversion Waterworks

以一种典型二次生活供水系统为例,介绍了系统的主要工作原理及变频器和PLC在多泵恒压供水系统中的应用,与传统系统相比,该方案设计先进,功能全面,同时节省了电耗,增加了可靠性,减少了水泵和管网损坏,对相近系统有重要的参考价值。

Giving an example of a typical secondary water supply system, this article introduces the main principle of the transducer and PLC and their applications in multi - pump isobaric water supply. Compared with traditional systems, this project has an advanced design and comprehensive functions. Thus it decreases the con sumption of electric energy, and at the same time enhances the reliability and reduces damage to pumps and pipes.
