Abstract

The invention relates to a novel hypersonic flame spraying gun. The novel hypersonic flame spraying gun mainly comprises a combustor shell body, a gun barrel shell body, a coaxial tail base, a combustor, a gun barrel, two high-pressure oxygen input pipes, two high-pressure liquid fuel input pipes, a catalysis ceramic chip, an ignition needle, power feeding needles, a water cooling sleeve and the like, wherein the gun barrel shell body and the coaxial tail base are coaxially fixed to the front end and the back end of the combustor shell body correspondingly; the combustor is arranged in the combustor shell body; and the gun barrel is arranged in the gun barrel shell body. Compared with traditional hypersonic flame spraying guns, the jet speed and the particle speed are significantly increased through the unique structural design of the novel hypersonic flame spraying gun, jetting of eleven mach cones can be achieved, the jet speed reaches 3500 m / s, and the particle speed reaches 1500 m / s.

Description

technical field [0001] The invention relates to a supersonic flame spray gun, in particular to a novel supersonic flame spray gun with high jet velocity and particle velocity. Background technique [0002] Hypersonic flame thermal spraying technology is widely used in various fields of industrial production, and has gradually become an indispensable process in the manufacturing process of many mechanical products, such as turbine blades, valves, gates, piston rods, steel structure bridges, etc., can Effectively improve the wear resistance, corrosion resistance, fatigue resistance and other properties of the equipment surface, and play a role in improving the performance and prolonging the service life. With the development in recent years, the hypersonic flame thermal spraying technology used in practical engineering at home and abroad is mainly divided into three categories: the first category is the hypersonic flame spraying technology using gas fuel (such as propane, etc....
