A servo-fluxed disc motor pump and method of use

Abstract

The application provides a servo flow distribution disc motor pump and a use method thereof, and belongs to the technical field of motor pumps.The servo flow distribution disc is provided with a high-pressure waist-shaped groove, a low-pressure waist-shaped groove, a center hole and a throttle hole on the front surface, and is provided with a compression piston cavity and a balance piston cavity on the back surface.When the motor pump is not started, the first compression spring in the compression piston cavity and the second compression spring in the balance piston cavity are pre-tightened by the compression plug and the balance compression plug, so that the servo flow distribution disc can be tightly attached to the cylinder body, and the sealing performance of the motor pump during starting is ensured.When the motor pump is started, the sum of the hydraulic compression force of the oil in the compression piston cavity and the compression spring force is slightly greater than the hydraulic separation force provided by the flow distribution pair oil film, so that the servo flow distribution disc is still tightly attached to the cylinder body.The servo flow distribution disc structure design can ensure that the flow distribution pair can form a good seal when the cylinder body produces a slight tilt, a slight axial displacement and a combined micro-motion, reduces leakage, and reduces the wear of the flow distribution disc.
