中文摘要: 根据泵/风机在不同工况下运行的性能与特点,分析变流量运行时,泵/风机流量、扬程(压头)、功率与转速间的关系,提出了变流量运行时,泵/风机采用变频技术的节能原理及经济效益.以某电厂鼓风机系统为例,分析比较了电厂鼓风机采用变频调节时的特性、耗能情况及其经济性.

中文关键词: 泵/风机变频器变频调速节能

Abstract:Based on the performance and characteristics of pump/fan, this paper analyzes the relationship between flow quantity,head,power and rotate speed.Application of variable frequency speed-control in pump/fan system is introduced. The traits, energy consumption and the economical features of the Pump/fan using frequency speed-control are analyzed and compared.

keywords: pump/fan freqency-converter frequency speed-control energy-conservation
