摘要(Abstract):

对离心泵在恒压变频调速状态下的特性进行了分析 ,提出了恒压变频调速幅度的确定方法 ,介绍了在离心泵定速特性曲线H Q、N Q、η Q的基础上获得其恒压变速状态下 [N -Q]、[η -Q]、[n -Q]特性曲线的方法。
The characteristic of the centrifugal pump in the condition of an invariable pressure, a fluctuant frequency and an adjustive speed was analyzed. The method that could confirm the range of the speed in the condition of an invariable pressure, a fluctuant frequency and an adjustive speed was brought fooward. The method obtaining the pump ,s characteristic curve ?? in the condition of a invariable pressure and a fluctuant speed was introduced.
