Experimental Study on Operation Characteristics of Variable Frequency Speed-regulating Pump in Opening System
Pages: 4-9
Year: Issue:  8
Journal: Gas & Heat

Keyword:  开式系统变频调速水泵阀门开度运行特性;
Abstract: 通过实验研究开式系统中水泵、变频器和电动机组合系统的变频调速运行特性.在改变水泵频率和系统中调节阀门开度的工况下,获得变频水泵在各种工况下的转速、流量、压头、总功率等数据,利用曲线拟合方法得到变频水泵全工况的流量比与频率比、压头比与频率比、总功率比与频率比之间的关系式.
