Abstract

The invention relates to a floating composite axial plunger pump valve plate. The floating composite axial plunger pump valve plate comprises an upper valve plate and a valve plate base, an O-shaped sealing ring is arranged on the valve plate base at the joint of the upper valve plate and the valve plate base, a center through hole is formed in the center of the upper valve plate and the valve plate base, an oil suction window is formed in one side of the center through hole, an oil pressing window is formed in the other side of the center through hole, vibration reduction grooves are formed in the front ends of inlets of the oil suction window and the oil pressing window, a micro unit body texture area is arranged on the upper valve plate between the oil suction window and the oil pressing window, and the micro unit body texture area is composed of a plurality of micro bosses. The floating composite axial plunger pump valve plate has the advantages of small friction force, less unbalance loading abrasion, leakage reduction, high volume efficiency, convenience in replacement, low cost, light weight and wide application range.

Description

technical field [0001] The invention belongs to the field of hydraulic pumps, and in particular relates to a floating composite axial piston pump flow plate. Background technique [0002] Axial piston pump is one of the most important hydraulic components, widely used in engineering machinery, metallurgical equipment, aerospace, transportation and other fields. In the practical application of the axial piston pump, it is found that the pressure distribution on the surface of the valve plate is uneven, which will generate an eccentric load moment, cause eccentric wear on the surface of the valve plate, reduce the volumetric efficiency, and reduce the service life. With the rapid development of science and technology, axial piston pumps are developing in the direction of high pressure, high speed and large flow, which puts forward higher requirements for the performance of axial piston pumps. development is extremely important. [0003] At present, neither the patented techn...
