In this paper, the A7VDR bent-axis axial piston pump is taken as an example to analyze its structural composition and constant pressure control principle. Aiming at the actual operation method in on-site debugging process, from the perspective of power transfer, combined with the theory of electrical engineering, through the study of the relationship among pressure, flow and motor current of the piston pump, the principle and method for pressure regulating of the A7VDR bent-axis axial piston pump in practical application are summarized.
