泵变频控制的节能原理及其系统分析

The principle of energy-saving of pumps with frequency conversion control and its systems analysis

依据变频技术原理,论证了泵变频调速运行节能的基本原理,从而阐明了泵站运行采用转速控制法比阀门控制法在节能上的优点.通过对泵站现行的控制系统和变频控制系统进行分析、比较,推导出工程上简单实用的变频调压供水系统的数学模型.

According to the principle of frequency conversion technology, the basic principle of energysaving of the pumps with frequency conversion for speed regulation was demon.strated, so that it was concluded that the energy-saving effect of speed-control in pump station was superior to that of valve-control. A mathematical model of simple and practicable water supply system with frequency conversion for pressure regulation was derived by means of analysis and comparison between the existing control system and the control system with frequency conversion.
