Description

Technical Field

[0001] The utility model relates to the technical field of supersonic flame spraying devices, in particular to a supersonic flame spraying device with a high degree of automation. Background Art

[0002] Supersonic flame spraying is a new type of thermal spraying technology developed in the early 1980s based on ordinary flame spraying. It uses hydrogen, acetylene, propylene, kerosene, etc. as fuel and oxygen as a combustion aid. It burns in a combustion chamber or a special nozzle to produce a supersonic flame. At the same time, powder is sent into the flame to produce molten or semi-molten particles, which collide at high speed and deposit on the surface of the substrate to form a coating.

[0003] The existing patent application number is: CN202223009195.5, and the patent name is: A utility model patent for a highly automated supersonic flame spraying device. The spray gun of the device drives the screw to rotate through a second motor, so that the spray gun can move evenly in one direction; although this type of equipment can ensure uniform coating spraying during spraying, since the spray gun needs to be connected to the feed pipe during use, there is a risk of loosening and leakage of the feed pipe joint during the long-term continuous movement of the spray gun, which needs to be improved.
