HD-8000 Supersonic Flame Spraying Equipment Introduction
The working principle of HD-8000 is to fully atomize kerosene with the combustion aid oxygen through the atomizing nozzle to form a combustible mixture gas. Under the action of force, the gas enters the combustion chamber. The ignition system ignites it and ignites it through the Laval nozzle to form a high-temperature and high-pressure supersonic flame flow. The powder feeding system sends the powder material from the low-pressure area into the flame flow channel, and after heating and accelerating, it sprays it onto the surface of the workpiece to form a high-quality coating.
HD-8000 Four advantages mainly:
- The fuel is aviation grade kerosene, and the combustion aid is oxygen. At present, this combustion mode is recognized internationally as the safest combustion mode;
- The spray gun structure is designed based on the principle of a rocket generator, with a maximum combustion chamber pressure of 150PSI and a flame flow velocity of over 2000m/s. The output power is large and can be adjusted steplessly;
- The spray gun adopts radial powder feeding, which is a new injection method that allows the powder to dissolve well and distribute evenly throughout the flame, improving coverage efficiency and coating quality;
- The fuel flow rate of the system adopts a fully closed-loop design, modular design, high-performance PLC control, and safe and easy operation;
