本文提出了混流泵变轴面速度设计的流动模型,建立了混流泵轴面速度与周向速度(环量)间的定量关系式——流型方程式;论述了流型函数的物理意义;给出了流型函数构成的基本原则,阐明了混流泵设计的主要步骤。
In this paper, the flow model of variable speed axial flow design of mixed flow pump was put forward. The quantitative relationship between flow velocity and circumferential velocity (flow rate) was established. The flow equation was discussed. The physical meaning of flow function was discussed. Out of the basic principles of the flow function constitute, clarified the main steps of mixed-flow pump design.
