【摘要】 从保证抽送黄河水用泵（以下简称抽黄泵）的寿命和工作可靠性出发，提出了抽黄泵性能参数选择的原则：限制抽黄泵的单级扬程Ｈ；限制抽黄泵单级扬程Ｈ与转速ｎ的乘积Ｈｎ值。并给出抽黄泵性能参数的Ｈ·ｎ－Ｑ关系曲线和泵的比转速ｎ＿ｓ与单级扬程Ｈ的关系曲线。更多还原

【Abstract】 In order to ensure required longevity and wording reliability of the pumps forwater pumping from Yellow River,the selection principle of the performance parameteres ispresented,which includes the limit of single stage head H and the limit of the production ofmutiplication value H· n single stage head H and pump speed n.H·n-Q curve and the curveof specific speed n_s versus single head H are also given.更多还原
