The HA10VS0/31 series axial piston pump adopts a swash plate structure, which realizes stepless volume adjustment by changing the inclination angle of the swash plate. When the swash plate is inclined, the stroke of the piston in the cylinder increases, thereby increasing the pump's displacement; conversely, reducing the inclination angle of the swash plate reduces the pump's displacement. This structure allows the pump to flexibly adjust the flow according to actual needs, improving the operating efficiency of the system.
