Research on the Volumetric Efficiency of a Novel Stacked Roller 2D Piston Pump

In order to improve the volumetric efficiency of axial piston pump, this paper proposes a novel stacked roller 2D pump. It utilizes alternate communication between distribution cylinder and oil intake discharge ports housing realize flow distribution. While removing independent mechanism traditional leakage loss at friction pair can be reduced efficiency. Based on principle, an analytical model pump was established. Then, co-simulation whole built using both Simulink AMESim software. The variation curve output under different load pressures rotational speeds obtained, as well influence backflow, leakage, circumferential On basis, prototype designed manufactured in measure speeds, dedicated test bench experimental results are consistent with simulation results; when speed is 6000 rpm pressure 5 MPa, reach 98.6%. research work validates that has high
