In order to study the effect of the structural style of high-speed pump on internal flow, 4 types high-speed pump of different structural style are selected for comprehensive analysis, S-A turbulence model and SIMPLIEC algorithm are adopted for numerical simulation of internal flow. By comprehensively comparing the static pressure, total pressure, sectional velocity vector and flow path line, two types of high-speed pumps with cylindrical-blade impeller matching nozzle type pump casing have relatively ideal pressure field and flow condition, can reduce hydraulic loss. The comprehensive performance of 4 types of high-speed pump is predicted through computational simulation, the high-speed pump with open cylindrical-blade impeller matching nozzle type pump casing has most excellent performance, indicating the structural style of high-speed pump has effect on its internal flow and performance.
