Abstract

The invention discloses a high-pressure seawater axial plunger pump valve friction pair with a bionic non-smooth surface. The high-pressure seawater axial plunger pump distribution friction pair is mainly characterized in that a plurality of concave pit unit bodies are arranged on one of the friction surfaces of a valve plate and a cylinder body of the friction pair or both the friction surfaces of the valve plate and the cylinder body to form a bionic non-smooth surface morphology, i.e., the friction pair is provided with a surface with the non-smooth surface morphology, and the surface can be a separated valve plate friction surface or can be a separated cylinder body friction surface or can be the valve plate friction surface and the cylinder body friction surface. According to the high-pressure seawater axial plunger pump valve friction pair disclosed by the invention, the lubricating capability, the bearing characteristic and the friction wearing performance of the high-pressure seawater axial plunger pump valve friction pair can be improved reasonably at high cost performance.

Description

[0001] Field [0002] The invention relates to a high-pressure seawater axial plunger pump, in particular to a novel valve plate / cylinder body friction pair. Background technique [0003] The high-pressure seawater axial piston pump is the core power component of seawater hydraulic transmission and reverse osmosis seawater desalination and other systems with seawater as the medium. The distribution friction pair composed of the distribution plate / cylinder block is one of the key friction pairs in the high-pressure seawater axial piston pump. The distribution plate is a disc with a central through hole, and an annular groove coaxial with the central through hole is provided on the friction surface between the central through hole and the outer peripheral surface. a semicircular through hole; the friction surface of the cylinder body corresponding to the friction surface of the distribution plate is set at one end of the cylindrical cylinder body, the central through hole of th...
