  • As the research object of inducer and impeller combination aero fuel centrifugal pumps, the outlet clearance optimization on axial-force of the pump was carried out. Through comparing the axial-force simulation data with theoretical calculation data, the axial-force trends of the two methods were identified similar and the simulation's accuracy was verified by Pumplinx because of the error less than 4%. Then the outlet clearance's influence on axial-force was analyzed. Simulation results show that expanding the clearance to 0.2mm increases the axial-force value, and reduces the pressure charging; but reducing the clearance to 0.1mm and 0.13mm can make optimizations of the axial-force, and the clearance of 0.1mm is the best. The axial-force performance of the model with clearance of 0.1mm was analyzed finally, showing that this model's inner performance of different sections is normal and steady; the axial-force value at design point is 3620N, so reducing the outlet clearance to 0.1mm can make a high optimization about axial-force of the inducer and impeller combination centrifugal pump.
