Zhengzhou Lijia Thermal Spray Machinery Co., Ltd

The HV-8000 supersonic flame spraying developed by Zhengzhou Lijia is a new type of HVOF system, which uses aviation-grade kerosene as a fuel system, and is currently one of the most popular kerosene fuel equipment in the world. Its basic principle is to fully atomize the kerosene through the atomization nozzle to form a combustible mixture into the combustion chamber, and the ignition system ignites the high-temperature and high-pressure gas, which is ignited by the Laval nozzle to form a high-temperature and high-pressure supersonic flame flow, and the powder feeding system sends the powder material from the low-pressure area into the flame flow, and sprays it to the surface of the workpiece to form a high-quality coating after the heating is accelerated.
HV-8000 equipment panel settings are all operated through the touch screen, with the world's leading 8 powerful functional modules, all kinds of common operations, information display and fault alarms are readily available, in line with the user's operating habits, simple and easy to use, stable quality.

Top 10 advantages of HV-8000 supersonic flame spraying equipment:
1) Touch screen operation, the equipment design structure adopts a full closed-loop automatic control structure, and the gas is all controlled by the mass flow controller, and the flow can be monitored in real time and automatically reach the process set value.
2) The fuel used is kerosene, and the accelerant is oxygen, which is the safest combustion mode in the current market;
3) The structure of the spray gun is designed according to the principle of rocket generator, the maximum combustion chamber pressure is 150PSI, the flame flow speed is more than 2000m/s, and the output power is large and can be adjusted steplessly;
4) The spray gun adopts radial powder feeding, which makes the powder better dissolved and evenly distributed in the whole flame, which improves the covering efficiency and the quality of the coating;
5) With the function of process formula storage and call, the parameters can be added, modified, and saved up to 8000 sets of process parameters, which can be called at any time.
6) The system design locates the temperature range in a certain range, and takes the speed improvement as the main goal of structural optimization; The coating has high bonding strength, high coating density, and the surface stress is compressive stress;
7) The fuel flow of the system adopts full closed-loop design, modular design, high-performance PLC control, safe and simple operation;
8) Combustion design produces particles up to 1100 m/s (3300 to 3900 feet per second), which is faster than conventional HVOF;
9) The thickness of the spraying coating is greater than 10mm (compressive stress coating), and the microhardness is higher than that of any other HVOF system (HV-80S spraying WC-Co coating microhardness is up to 1450);
10) HV-8000 coating can reach 70MPa binding strength.
