Description

Technical Field

[0001] The utility model relates to the technical field of plasma paint spraying equipment, in particular to a plasma paint spraying processing electromechanical equipment. Background Art

[0002] Plasma spraying is a technology for strengthening and modifying the surface of materials. It uses a plasma arc driven by direct current as a heat source to heat materials such as ceramics, alloys, and metals to a molten or semi-molten state, and then sprays the material at high speed onto the pre-treated workpiece surface to form a firmly adhered surface layer. This spraying technology is widely used in the surface treatment of solar power generation equipment and wind power generation equipment.

[0003] When plasma spraying is used, a DC arc is generated between the cathode and the anode. The arc heats the air flow in the spray gun into a high-temperature plasma and ejects it from the nozzle to form a plasma flame. The metal powder is fed into the powder inlet of the spray gun through a powder feeder and then enters the plasma jet. The metal powder is melted and accelerated to be sprayed onto the engine surface to form a coating. However, the spray gun structure of some existing plasma spraying processing electromechanical equipment is relatively simple, and its powder inlet is usually two symmetrically distributed slots. After the metal powder enters the plasma jet from the powder inlet, its movement trajectory diverges due to inertia, and some of the floating powder cannot be melted by the plasma jet, thereby causing pollution and waste. In addition, the utilization rate of the metal powder is low, resulting in low spraying efficiency. Therefore, a plasma spraying processing electromechanical equipment is proposed to address the above problems. Utility Model Content
