Zhengzhou Lijia Thermal Spray Machinery Co., Ltd

The HA-2000 supersonic flame spraying developed by Zhengzhou Lijia is a new type of HVAF system, which heats the powder after ignition by generating a high-speed air flow of compressed air and propane fuel, accelerates the powder to more than 700m/s, and hits the substrate to form a coating with extremely low oxygen content and extremely high density.
HA-2000 spraying system is a set of spraying equipment developed by many engineers of our company on the basis of introducing, absorbing and digesting international advanced equipment and technology.
The equipment panel settings are all operated through the touch screen, with the world's leading process setting, spraying monitoring and other functional modules, all kinds of common operations, information display and fault alarm, which is very in line with the user's operating habits, simple and easy to use, and stable quality.
The main advantages of the HA-2000 system are as follows:
1) Touch screen operation, the equipment design structure adopts a full closed-loop automatic control structure, the gas is all controlled by imported pressure sensors and pressure regulators, and the pressure can be monitored in real time and automatically reach the process set value;
2) The fuel used is propane, and the accelerant is air, which is the safest combustion mode of the gas model in the market;
3) The structure of the spray gun is designed according to the principle of rocket, the flame flow speed reaches more than 2000m/s, the output power is large and can be adjusted steplessly;
4) The spray gun adopts axial center powder feeding, which is a new injection method that makes the powder better dissolved and evenly distributed in the whole flame, which improves the covering efficiency and the quality of the coating;
5) It has the function of storing and calling process formulas, and the parameters can be added, modified and saved;
6) The fuel of the system adopts full closed-loop design, modular design, high-performance PLC control, safe and easy operation;
7) The coating has high bonding strength, low porosity, and ≤1%, reaching the international leading level. High spraying efficiency (up to 20 kg of powder per hour)
