Problems solved by technology

However, the valve plate with integral structure cannot adjust the position of the distribution window itself. After being fixedly connected with the end cover of the corresponding pump, it can only realize the fixed oil suction and discharge volume of the pump, so it cannot realize the double-row axial piston pump. Displacement variable

Abstract

The invention discloses a sluice flow valve plate for a double-row axial plunger pump. The sluice flow valve plate comprises an outer layer surface, an inner layer surface, a rubber ring and a tightening screw. The inner layer surface is arranged in the outer layer surface and is tightly attached to the outer layer surface, and the inner layer surface and the outer layer surface are tightly attached to form an outer pressure oil discharging window, an inner oil discharging and absorbing window, an inner pressure oil discharging window and an outer oil discharging and absorbing window. The inner layer surface is rotated, the relative angle between the inner layer surface and the outer layer surface is adjusted to change the position of each flow distribution window so as to brake off part of pressure oil discharged from an oil pressing area, and meanwhile, the corresponding structure of the flow distribution disc introduces the part of the pressure oil which is switched off into an oil suction area, so that the displacement variable problem of the double-row axial plunger pump is solved. The valve plate is of a split combined structure.

Description

technical field [0001] The invention relates to the technical field of hydraulic components, in particular to a gate flow distribution plate for a double-row axial plunger pump, which belongs to the scope of plunger pump components. Background technique [0002] Axial piston pump is one of the important power components in the hydraulic transmission system. Because of its compact structure, high working pressure and high volumetric efficiency, it is widely used in aerospace, engineering machinery, plastic machinery, metallurgy, machine tools and agricultural machinery. . [0003] At present, the axial piston pump generally adopts changing the inclination angle of the swash plate, so that the volume change range of the closed space formed by each plunger and the cylinder changes every one rotation of the cylinder body, thereby changing the displacement of the pump. However, the double-row axial piston pump is a new type of axial piston pump. Its swash plate structure is quit...
