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...

Abstract

The invention relates to the hydraulic design of an axial flow pump, and discloses a hydraulic design method of an axial flow heavy metal pump operating under an extreme high temperature working condition. The main flow-passing parts of the axial-flow heavy metal pump designed by the present invention are composed of four parts: suction chamber (1), impeller (2), guide vane (3) and diffuser pipe (4). Hub ratio dh / D, airfoil placement angle β′, blade density l / t, number of impeller blades Zy, number of guide vane blades Zd, guide vane cone angle γ1, distance between guide vane inlet side and impeller outlet side The distance L1, the length of the diffuser tube L2 and the diffuser angle γ2 of the diffuser tube are hydraulically designed. On the premise of ensuring the good safety characteristics of the pump, it has good hydraulic performance and cavitation performance, making the pump more reliable.

Description

technical field [0001] The invention relates to the hydraulic design of an axial-flow pump, in particular to a hydraulic design method for an axial-flow heavy metal pump operating under extreme high-temperature conditions in a solar thermal power generation system or a nuclear power plant system. Background technique [0002] In the past hundred years, with the rapid development of society, economy and technology, human's demand for energy has been increasing day by day, and energy has become a necessary condition for promoting the development of human society and economy. However, with the reduction of fossil energy reserves and the increasingly prominent environmental problems, the development of new and renewable energy has become a current hot issue. Renewable energy such as solar energy, hydropower, wind power, biomass energy, wave energy, tidal energy, ocean temperature difference energy, etc. Solar energy is currently being praised by many scientists as a potential en...
