Water-pressure axial plunger pump piston shoe pair with lotus leaf-like texture surface

Abstract

The invention discloses a water-pressure axial plunger pump piston shoe pair with a lotus leaf-like texture surface, and relates to the technical field of water hydraulic elements. The piston shoe pair comprises a swash plate and piston shoes, wherein a cross-scale secondary texture is arranged on the surface of the swash plate, and the secondary texture comprises a convex body fixedly connected to the surface of the swash plate and a small convex body or a small concave pit fixedly connected to the convex body. The piston shoe pair solves the problem of aggravation of frictional wear of water-pressure axial plunger pump piston shoe pairs and other water hydraulic element friction pairs at present, reduces the water film adhesion and friction coefficients of the surfaces of the swash plate and the piston shoes of a water-pressure axial plunger pump in the friction process, and has high wear resistance and good resistance-reducing and wear-resisting effects.

Description

Technical field [0001] The present invention relates to the technical field of hydrothermal pressing elements, in particular, a water pressure axial plunger pump skating boots on the surface of the impeller leaf fabric surface. Background technique [0002] The hydraulic axial plunger pump is high in its capacity, high working pressure, compact structure, and has become the preferred power component in the field of water hydraulic transmission technology, which is played in seawater, ocean ore oil development, marine ship transportation and other projects. Key role. Using pure water instead of hydraulic oil as a drive medium, it can greatly alleviate the pressure brought about by tension and ecological environment deterioration. However, the viscosity of water is low, the lubricity is poor, the corrosion is strong, especially the most complex side of the lace, especially the motion and force, the most complex, the most complex, the most complicated lace is very affected, and the ...

AI Technical Summary

Problems solved by technology

However, water has low viscosity, poor lubricity, and strong corrosion, which has a great impact on the tribological properties of the key friction pairs running in it, especially the sliding shoe pair with the most complicated movement and force, and is prone to increased gap leakage, water Key technical problems such as reduced membrane load-carrying capacity and increased friction and wear lead to phenomena such as shoe burning and gluing, which seriously affect the quality efficiency, working reliability and service life of hydraulic axial piston pumps
