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。
After a lot of investigations and studies, through theoretical analysis and design and test of many axial-flow hydraulic models of hydraulic pumps with different specific rotational speeds, the main parameters influencing axial-flow pump performance are analyzed. Based on this, Several Curves for Selecting Design Parameters of Axial Flow Pump Hydraulic Model. The statistics show that the main parameters of the axial-flow pump with good performance are all close to the curve recommended in this paper. Therefore, the curve recommended in this paper can be used as a reference for the selection of design parameters when designing the axial-flow pump.
