Abstract:

A flow field model of inside pump head was setup herein. Inlet integrated passage and outlet integrated passage could be simplified as the Venturi passage structure. Optimal design was applied for inside passage structure of pump head, the simulation and testing results show that the optimization achieves the pressure loss reduction of the Venturi passage and the unloading balance pressure decrease of the bypass.

Key words: swash plate axial piston pump, Venturi passage, flow field simulation, optimal design
