Raising the Speed Limit of Axial Piston Pumps by Optimizing the Suction Duct

Abstract The maximum delivery pressure and the maximum rotational speed determine the power density of axial piston pumps. However, increasing the speed beyond the limit always accompanies cavitation, leading to the decrease of the volumetric efficiency. The pressure loss in the suction duct is cons...
