通过实际设计和样机试验,对旋转喷射泵（以下简称旋喷泵）设计方法和参数的选择进行分析,探讨,总结。给出了旋喷泵复合叶轮的叶片数,进、出口安放角,叶轮出口宽度,叶轮外径,短叶片起始直径,短叶片在流道中的位置,叶轮流道出、入口面积比等的计算方法和取值范围。经试验验证,按文中方法设计的旋喷泵性能达到了设计指标和要求,表明文中所述的设计方法及相应参数的选择具有实用价值。
Through the actual design and prototype test, the choice of rotary jet pump (hereinafter referred to as rotary jet pump) design methods and parameters are analyzed, discussed and summarized. The number of blades, entrance and exit angle of entry, outlet width of impeller, outer diameter of impeller, initial diameter of short blade, position of short blade in the flow path, outlet of impeller, ratio of entrance area and so on are given Calculation method and value range. The experimental verification shows that the performance of the rotary jet pump designed according to the method in the text has reached the design specifications and requirements, indicating that the design method and the corresponding parameter selection described in the text have practical value.
