Description

Technical Field

[0001] This utility model relates to the field of plasma spray gun technology, specifically a rotary plasma spray gun. Background Technology

[0002] A rotary plasma spray gun is a device that uses plasma technology for material surface treatment or coating deposition. It generates a high-temperature, high-speed plasma jet to heat the material to a molten or semi-molten state, accelerating it before spraying it onto the substrate surface to form a coating with specific properties. The rotary plasma spray gun is characterized by its unique plasma generation and acceleration method, typically involving the confinement and acceleration of the plasma by a magnetic field, making the spraying process more efficient and stable.

[0003] However, in the existing technology, such plasma spray guns are more troublesome and inconvenient to spray when the inner sidewalls of some equipment need to be coated. In addition, the weight of the plasma spray gun is much heavier than other spray guns, which is also more inconvenient for workers to handle and use. Therefore, a rotary plasma spray gun is needed to solve the above problems. Utility Model Content
