Supersonic spray gun is generally used for spraying outer surface of workpiece, for small space of the diameter within 500mm, uses
Conventional supersonic spray gun spraying small space inner surface difficult to realize, because conventional lance flame is axially spraying, no
Direction and the angle of flame can be changed, so being sprayed for inwall or endoporus, special elbow endoporus spray gun can only be used, it is this
The gun barrel of spray gun has 60 degree or 45 degree of angles with combustion chamber, and the common endoporus supersonic spray gun of spraying inwall is all adopted
With fuel gas, the pressure of gaseous fuel is not high, and this spray gun chamber pressure in burning is low, the flame speed of formation compared with
Low, in endoporus of the spraying than narrow inner-walls of duct or some workpiece, the particle rapidity of spraying is general in 500m/s, grain
Sub- striking work surface forms coating, high for coating needs bond strength（More than 80Mpa）, porosity is low（Less than 1%）Shape
Condition, this combustion gas endoporus spray gun does not reach requirement.
Utility model content：
Technical problem to be solved in the utility model is：Overcome the deficiencies in the prior art can be further there is provided one kind
Improve flame speed（1000m/s）, improve anchoring strength of coating（More than 80Mpa）, reduction porosity（Less than 1%）Liquid combustion
Expect endoporus supersonic spray gun.
The utility model is as follows to solve the technical scheme that technical problem is taken：
A kind of liquid fuel endoporus supersonic spray gun, including the gun barrel in gun housing and gun housing, in addition to oxygen conveying
Pipeline, fuel delivery line, ignition lead pipeline, atomizer, stabilizer, combustion chamber, high temperature and high pressure gas convergence section, elbow connection
Device, powder feeding pin, gas compression throat, flame spread section, nozzle, bottom of combustion chamber delivery port, spark plug and cooling water inlet pipe
Road；The combustion chamber is located at the inside of the gun housing, and the atomizer is arranged on the fuel delivery line and the stabilizer
The position being connected, the spark plug is arranged on the position that the ignition lead pipeline is connected with the stabilizer, the burning
Room one end is provided with described stabilizer, the other end and is provided with described elbow connector, and the combustion chamber connects with the elbow
Connect the pipeline connected after device connection and be followed successively by high temperature and high pressure gas convergence section, gas compression throat and flame spread section, it is described
Nozzle is arranged on the end of the flame spread section；The powder feeding mouthful of the powder feeding pin is located at the interposition of the elbow connector
Put.
The cooling water inlet pipe road through described combustion chamber, high temperature and high pressure gas convergence section, gas compression throat and
Flame spread section.
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 elbow connector, and gas is compressed again, then by throat,
Flame is turned to, diffuser is entered back into, supersonic airstream is formed；
4th, powder enters flame core from the powder feeding pin of elbow connector, and the flame come out from diffuser continues to add along gun barrel
Speed, powder obtains heat in flame and burnt to molten condition, accelerates to spray from the gun barrel port of export by flame stream.
The utility model, as fuel, can produce higher temperature and pressure using liquid aviation kerosine in burning,
With reference to peculiar structure of the present utility model, flame speed can be effectively improved（1000m/s）, improve anchoring strength of coating（It is more than
80Mpa）, reduction porosity（Less than 1%）.
