Supersonic flame spraying equipment and spraying method thereof

Abstract

The invention provides supersonic flame spraying equipment and a spraying method thereof. The supersonic flame spraying equipment comprises an air compressor, a heat exchanger, a main control cabinet,a pressurizing pump, an oil tank, an oxygen bus bar, a machine shell, a base, a powder feeder, an extension pipe, a supersonic fame spraying gun, an angle-adjustable supporting frame, a height position movable adjustment rod, a spattering-preventive collection cover for remaining sprayed powder, a powder pollution-preventive adsorption exporting core and a V-shaped connecting frame. According tothe supersonic flame spraying equipment, a first lining seat, a second lining seat, a joining lining seat, an angle motion bar, a sliding pipe, a third lining seat and a telescopic adjustment rod arearranged; adjustment of the telescopic adjustment rod through extension and contraction is benefited; the sliding pipe slides on the outer wall of the angle motion bar, and at this moment, the angle motion bar moves inside the first lining seat, the inclination angle of the angle motion bar is changed, and the spraying angle of the supersonic flame spraying gun is changed; and finally, extension and contraction work of the telescopic adjustment rod is stopped so that the spraying work can be guaranteed to proceed smoothly.

Description

technical field [0001] The invention belongs to the technical field of supersonic flame spraying, and in particular relates to a supersonic flame spraying equipment and a spraying method thereof. Background technique [0002] The current supersonic flame equipment system (HVOFSPRAYINGSYSTEM) is mainly used in the field of anti-wear and anti-corrosion spraying engineering for industrial parts. The equipment uses the mixed combustion of propane and oxygen as the heat source. Its flame temperature is moderate and the particle flying speed is fast. The obtained coating has the advantages of high bonding strength, low porosity and high spraying rate. This equipment can be used in chemical industry, steel , metallurgy, shipbuilding, automobiles, railways, printing and papermaking, machining, environmental protection, special material manufacturing and many other fields. The structure of the traditional supersonic flame spraying equipment, especially the structure of the powder fe...
