摘要

Targeting the multi-diversion aero fuel centrifugal pumps with ejector, the numerical simulation of the centrifugal pump was performed. By comparing the simulation data with test data, the simulation's accuracy was identified by Pumplinx. The inner flow characteristics of the model were calculated by analyzing the pressure of middle axial and middle radial areas. Then cavitation characteristic was simulated in the worst operating conditions; and the gas-liquid two-phase distribution of the pump's full cavitation state was given at its Δh values and Δh-H curve was acquired. Studies have shown that this centrifugal pump's head, efficiency and cavitation characteristic curve of numerical simulation meet the test data. Pressure of inner flow is steady, and could make high pressure at high efficiency under small flow states; meanwhile, it could not produce cavitation within its operating range at the input pressure of 0.018 MPa, less than the input pressure of 0.027 MPa for technical requirements at its full cavitation state.
