| 摘 要： | 针对广大农村选泵时以井的深度为泵扬程的现象,从理论上分析了改变叶轮外径调节水泵工况的原理,并在泵站效率最大时,求出泵站的最优工况点,推导出了改变叶轮外径调节泵站工况时叶轮外径的相对切割量,并将该方法应用于具体的工程实例,使该泵站的效率提高了2.2%.

| Abstract: | Aimed at the phenomenon that in villages the depth of the well is taken as pump's head to select pump,the principle of condition regulation of water pumps by changing impeller diameter was theoretically analyzed.Optimal operational condition of pump station was obtained when it worked at maximum efficiency,and the relatively-truncated amount of impeller diameter was deduced for regulating operation condition of the pump station.The method was applied to a typical pump station and its efficiency was increase by(2.2 %.) |
