When supersonic spray gun burns, the temperature of combustion chamber is universal at 3000 degree or so, and this temperature is usually can not
Effectively adjust, this temperature is when spraying the powder of 1000~2000 degree of fusing point, best results, but closed in spraying low temperature
When gold, material below 1000 degree of warm area, superfusion occurs in powder, for the powder of less than 500 degree fusing points, it is also possible to can cause
Gasification, it is impossible to realize the spraying of cryogenic material alloy.
Utility model content：
Technical problem to be solved in the utility model is：A kind of supersonic flame of sprayable low-temperature metal material is provided
Spray gun, can control spraying temperature, realize the spray process of cryogenic material alloy.
The utility model is for the technical solution adopted for solving the technical problem：
A kind of supersonic spray gun of sprayable low-temperature metal material, including gun housing, in addition to the spray of stabilizer, oxygen
Mouth, atomizer, spark plug, cooling water inlet pipe road, combustion chamber, flame convergence section, upside compressed air inlet port, flame spread
Section, hollow gun barrel, powder feeding pin, cooling water return duct, downside compressed air inlet port, cooling water outlet and middle connection
Device；The combustion chamber is located at the inside of the gun housing, and described combustion chamber one end is provided with described stabilizer, the other end and is provided with
Described intermediate connector, the upper and lower sides of the intermediate connector are respectively arranged with described upside compressed air inlet port with
Side compression air inlet, the combustion chamber, flame convergence section, the burning of flame spread section and hollow gun barrel composition flame are launched
Passage, the powder feeding pin is located on the cool-down nozzle of the hollow gun barrel end.
Behind combustion chamber, flame convergence section, flame spread section and hollow gun barrel described in cooling water inlet pipe road insertion
It is connected with described cooling water return duct.
The course of work of the present utility model is as follows：
1st, fuel oil injects combustion chamber from the atomizer on stabilizer, and oxygen is entered by the oxygen jet on stabilizer to burn
Room, then oxygen will enter combustion chamber with oxygen mix after fuel-oil atmozation；
2nd, by plug ignition, mixture in combustion chamber is fully burnt, high temperature and high pressure gas are formed；
3rd, high temperature and high pressure gas enter convergence section by the inner bore of pipeline of intermediate connector, and gas is compressed again, together
When from the radial hole injecting compressed airs of intermediate connector both sides, make the reduction of high-speed flame temperature, enter back into diffuser, formed low
Warm supersonic airstream；
4th, powder enters flame core from the both sides powder feeding pin of nozzle end cool-down nozzle, and low-temperature alloy powder is obtained in flame
Less heat is incendivity to molten condition, accelerates to spray from the gun barrel port of export by flame stream.
The utility model uses liquid fuel aviation kerosine, can control spraying temperature, realize cryogenic material alloy inwall
Spray process.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
