Component	Characteristic	Parameter
E-2000 Powder feeder	1. The powder feeder is a high-precision powder feeding mechanism based on the principle of toothed dial with vibration structure and gravity falling, with uniform powder output and wide particle size range. 2. After the top cover is sealed, the powder condition in the powder cylinder can be clearly seen through the visual transparent observation window on the powder cylinder. 3. Nitrogen or argon with small flow is used as powder gas. The powder is rotated to the powder outlet along with the powder tray at the bottom and enters into the spray gun together with the powder gas. 4. Adopting the latest international turnover structure, it is convenient to clean the powder, which can be discharged from the lower mouth, or can be poured from the barrel body.	1. Powder feeding: toothed dial 2. Cleaning method: barrel body flip 3. Volume of powder storage tube :2L 4. Powder feed gas: nitrogen 5. Powder feeding air pressure: 0.15-1.2mpa 6. Powder feeding speed :0~500g/min 7. Powder feeding accuracy :±1% 8. Powder size :1~150 m

HA-2000 has many functions and features, and its advantages are mainly reflected in the following aspects:
1) Touch screen operation, the design structure of the equipment adopts full closed-loop automatic control structure, the gas is all controlled by pressure sensors imported from the United States and pressure regulating valves imported from Japan, the pressure can be monitored in real time and automatically reach the set value of the process.
2) The fuel is propane and the combustion-supporting agent is air, which is the safest combustion mode among the gas models in the market at present;
3) The structure of the spray gun is designed according to the principle of the rocket generator. The flame flow speed reaches over 2000m/s, with large output power and stepless adjustment;
4) The spray gun adopts axial center powder feeding. This new injection method makes the powder dissolve well and distribute evenly in the whole flame, which improves the coverage efficiency and coating quality;
5) It has the function of process recipe storage and invocation. Parameters can be added, modified and saved.
6) The system fuel adopts full closed-loop design, modular design, high-performance PLC control, safe and simple operation;
7) The coating produced has excellent performance with low porosity less than 1% (average porosity less than 0.5%) and high spray efficiency (up to 30KG powder per hour).

At present, Zhengzhou Lijia has developed the inner hole tungsten carbide spraying process and equipment for the diameter of more than 100mm. As the core of the supersonic flame inner hole spraying equipment, Lijia adopts HV-80D type kerosene supersonic flame inner hole spraying gun. The inner hole spray gun adopts the world's original design structure, and has obtained the national invention patent, patent number: X and the continuous design structure innovation and optimization, the spray gun is the world today, only using fuel and oxygen combustion auxiliary supersonic spray gun with the smallest diameter, the gun front end diameter is only 80mm, currently can penetrate into the narrow space within 100mm for spraying operations. At present, it has been successfully applied to the spraying of narrow space in a variety of industries.
The technology is mainly used for inner hole, hydraulic parts, cylinder, valve body, the compressor bore, shell lumen, inside the container, eight hole and internal condition, in the narrow space can be realized by this technology in the inner diameter 100 mm above the wall coating cemented carbide coating, the coating hardness, vickers hardness above HV1100, wear-resisting, anti-corrosive, high temperature resistance, and other functions, At present, Zhengzhou Lijia is actively research and development for smaller inner hole spraying, plans to develop the inner diameter of 80mm in the second half of this year to develop cemented carbide spraying technology, at present, our company to undertake a large number of inner hole tungsten carbide spraying business, welcome friends to visit.
