Title:
HIGH-PRESSURE GEAR PUMP THRUST PLATE AND METHOD FOR DESIGNING COMPENSATION OIL GROOVE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/284019
Kind Code:
A1
Abstract:
A high-pressure gear pump thrust plate and a method for designing a compensation oil groove thereof. The method comprises: calculating pressure forces of various regions of a high-pressure gear pump under a rated work condition, and calculating a resultant force and an action point of the resultant force according to the pressure forces of the various regions and action points of the pressure forces; calculating various component forces received by a thrust plate, and establishing a balance equation A according to resultant force balance of the thrust plate under a high-pressure condition; calculating, on the basis of the various component forces received by the thrust plate, torques of the various component forces on the thrust plate relative to an X axis and a Y axis, and establishing a balance equation B according to torque balance; and adjusting the area, shape, and position of a compensation oil groove on the thrust plate according to the balance equation A and the balance equation B. According to the method, a pressure compensation oil groove is designed on a gear pump, so that a thrust plate keeps stable work under a high-pressure condition, thereby achieving a pressure compensation effect and prolonging the service life of a thrust plate and a high-pressure gear pump.
