| 摘 要： | 根据相似理论，分析和表达了模型泵及泵装置扬程特性曲线和效率特性曲线，提出了预测原型泵及泵装置扬程特性和效率特性的数学模型，作为泵站技术改造水泵选型预测的理论依据；应用该数学模型对安徽上桥泵站技术改造中适宜的泵水力模型进行了比较、分析，预测了原型泵装置性能；以效率最优为准则，优选了适合于上桥泵站特征水位组合、流量的水力模型．优选结果为采用350ZMB-3．8模型；更换新泵后，在功率未增大的情况下，单泵流量加大5—8m^3／s．

| Abstract: | Based on similarity theory and expressions of water head and efficiency curves of pumps and pump sets, a mathematical model for predicting water head and efficiency of prototype pumps and pumping sets is put forward. According to the model, the pump set characteristics are predicted and the optimal hydraulic model of pumps suited to the Shangqiao Pump Station is selected. The optimal selection result is 350ZMB - 3.8 model. After reconstruction, the single pump flow rate increases by 5-8 m^3/s under the same input power. |
