AI Technical Summary
Existing axial piston pumps have low flow output efficiency under high pressure conditions, making it difficult to meet the instantaneous high flow requirements of large equipment. Furthermore, their single displacement design cannot flexibly match diverse load conditions, resulting in severe energy loss, which is inconsistent with the development trend of energy conservation and emission reduction.
The design employs a swashplate mechanism to achieve a bidirectional oil suction and discharge structure. The combination of the ball head and the slipper enhances the sealing performance, and the support of the limiting cylinder and the fixing ring improves the structure's resistance to deformation and reduces frictional resistance and energy loss.
It significantly improves hydraulic oil output efficiency, flexibly matches load conditions, reduces leakage and wear, extends equipment life, and meets energy-saving design goals.
