Study on Flow Field Optimization of Flow Distribution Disk of Double-unloaded Groove Piston Pump

SONGYuning (Yingkou Institute of Technology, Department of Mechanical and Power Engineering)

Abstract


By referring to all kinds of research data and summarizing the analysis and research of various kinds of distribution disks, a new type of distribution disc with double V-shaped unloading slots is designed again. Then, the new designed disk is loaded into the piston pump by CFD software to simulate. Finally, through simulation, it is concluded that the width of the triangle slot of the distribution plate is about 10 °, the slope angle is about 12°, and the diameter of the unloading hole is about 0.8mm. When the diameter of the perforated hole is about 1.5mm, the flow curve of the unloading hole is the smoother. Pressure shock and noise are also minimized at this time. Draw By improving the damping tank, the flow noise and cavitation change are smaller than before.
