【摘要】 经过大量的调查、研究,通过理论分析以及对不同比转速的许多轴流泵水力模型设计、试验研究,对影响轴流泵性能的主要参数进行了分析,在此基础上得出了性能良好的轴流泵水力模型设计参数选择的若干曲线。统计表明:性能好的轴流泵的主要参数均接近本文所推荐的曲线,因此,本文所推荐的曲线可作为设计轴流泵时选择设计参数的参考。更多还原

【Abstract】 Through a lot of investigations, designs and experimental researches about propeller pumps of different specific speed, an analysis of main parameters which may influence the performance of propeller pumps is given. On this basis, several curves of design parameters of hydraulic model of propeller pumps with good performance have been obtained.The statistical results indicate that the main parameters of propeller pumps with good performance are closed to the curves recommended in this paper. For this reason, the curves recommended in this paper can be used as a reference of parameters selection for propeller pump design.更多还原
