Embodiment Construction
[0052] Figure 1 to Figure 5 It is a schematic structural diagram of an embodiment of the present invention and a schematic cross-sectional diagram of each flow-passing component. The invention provides a hydraulic design method of an axial-flow heavy metal pump. The axial-flow heavy metal pump works under extreme high-temperature conditions, and the conveying medium is high-temperature liquid metal. The main flow-through components are composed of a suction chamber (1), an impeller ( 2), the guide vane (3) and the diffuser tube (4) are composed of four parts. The structural parameters of the heavy metal axial flow pump include the outer diameter of the impeller D, the hub ratio, the airfoil placement angle, the leaf density, the number of guide vane blades, The cone angle of the guide vane body, the distance between the inlet side of the guide vane and the outlet side of the impeller, the length of the diffuser tube and the divergence angle of the diffuser tube are used for h...
