Description
Affiliated field
The present invention relates to a kind of high pressure sea water axial piston pump, relate in particular to a kind of novel thrust plate/cylinder body friction pair.
Background technique
High pressure sea water axial piston pump is the core drive element of the system such as sea water hydraulic transmission and reverse osmosis seawater desalting take seawater as medium.The flow friction pair of thrust plate/cylinder body composition is one of crucial friction pair in high pressure sea water axial piston pump.Thrust plate is the disk that has central through bore, is provided with the annular groove coaxial with central through bore on the rubbing surface between central through bore and outer circumferential face, is provided with two semi-circular through hole between this annular groove and central through bore; The cylinder body rubbing surface corresponding with thrust plate rubbing surface is located at one end of cylinder block, the central through bore of cylinder body rubbing surface is corresponding with the central through bore of thrust plate, on the rubbing surface between cylinder body central through bore and outer circumferential face, be also provided with the annular groove coaxial with central through bore, this annular groove is corresponding with the annular groove on thrust plate.Cylinder body annular groove and and central through bore between be provided with discontinuously six uniform arc-shaped through-holes, they are corresponding with two semi-circular through hole on thrust plate.On rubbing surface outside cylinder body circular groove, be provided with six uniform radial opening grooves.Flow friction pair is owing to being operated in briny environment, in addition at a high speed, heavy duty, thereby very easily burn into wearing and tearing, and then cause losing efficacy, have a strong impact on normal use and the working life of high pressure sea water plunger pump.The problem that the expert of association area exists for high pressure sea water Cylinder Block in Axial Piston Pump friction pair is both at home and abroad being studied always, but the thinking of dealing with problems is to seek to meet wear-corrosion resistance, resistance to wear and have the pairing material of self-lubricating property.By the manufacture of studying and engineering practice engineering plastics, engineering ceramics, surface engineering material and special, wear-resistant lose the applicable flow friction pair of alloy ratio.More than study comparatively perfect, but lubricating ability, bearer properties, friction and wear behavior and the life-span of how further to improve high pressure sea water Cylinder Block in Axial Piston Pump friction pair still wait the problem solving.
Summary of the invention
The object of this invention is to provide a kind of can improvement in the lubricated environment of seawater, at a high speed, lubricating ability, bearer properties, the high pressure sea water Cylinder Block in Axial Piston Pump friction pair with bionic non-smooth surface of friction and wear behavior of flow friction pair under the condition of heavy duty.The present invention is mainly according to bionic non-smooth surface effect, the flow friction pair friction surface of high pressure sea water axial piston pump is processed into the non-smooth surface of the pit cell cube formation with certain form.
Concrete scheme of the present invention is as follows: the flow friction pair that the present invention includes thrust plate and cylinder body composition.The thrust plate of this friction pair and the friction surface of cylinder body both one of or both are double is provided with some pit cell cubes, form bionic non-smooth surface form, to have the surface of non-smooth surface form can be independent thrust plate friction surface to this friction pair, also can be independent cylinder body friction surface, can also be two surfaces of thrust plate friction surface and cylinder body friction surface.The preferably dark 0.01-3mm of pit cell cube.On the friction surface of thrust plate and cylinder body, the opening area of pit cell cube is 0.8-12mm
2.Above-mentioned pit cell cube is arranged evenly and regularly, regularity of distribution form, can be uniformly distributed, the form such as radial distribution, concentric circles distribution, distributed in grid.The shape of above-mentioned pit cell cube has multiple, for cylindrical, conical, hemisphere, goalpost shape, fall truncated cone shape,, bowl type cylindrical with chamfering, one or more in hemisphere or semielliptical shape of falling, these forms can be used separately or mix use.
The present invention compared with prior art tool has the following advantages:
1, research nature large number of biological, as the lizard of mountain region and desert region, snake class, the earthworm in soil, marine shellfish and shark, plant bamboos etc., find that these biologies generally have good desorption, drag reduction and wear-resisting function, and these functions are relevant with its body surface non-smooth surface form.The present invention is according to bionic non-smooth surface effect, high pressure sea water Cylinder Block in Axial Piston Pump friction pair friction surface is processed into the non-smooth surface with certain form, these pit cell cubes meeting storage part seawater, seawater in pit can be coated to friction surface in the course of the work, has improved lubricating condition; Can form local dynamic pressure at pit cell cube place and support, improve its bearer properties simultaneously; These pit cell cubes can store the granular abrasive particle in Seawater in addition, prevent that these abrasive particles are brought to friction surface, have improved tribological property.Can greatly improve like this lubricating condition between friction pair rubbing surface, thereby reach the object of drag reduction anti-attrition, improve the wear resistance of friction pair, the working life of prolongation friction pair.
2, the present invention does not increase any part, has only improved the performance of flow friction pair by structural design, have simple in structure, reliable performance, with low cost, cost performance advantages of higher.This technology has personalized strong feature in addition, can, for different operating requirement, select the bionic non-smooth surface of different units volume morphing, size, the regularity of distribution, thereby obtain excellent performance.
