Characteristics and advantages of HV-80-JP supersonic flame spraying system

1, Solid cabinet design, fuel flow control area, pressure display area, electronic control area are modular layout, panel clear and easy to operate.
2. All imported valves, pressure switches, flow switches and sensors from Europe and America are of the same quality as those from Europe and America
3, The use of Japanese mitsubishi high-performance PLC control, after ignition automatically maintain oxygen and fuel, carrier gas flow output.
4. All the internal fuel, oxygen, carrier gas and cooling water connected on the equipment have the detection function to ensure that all preparation processes can be fully tested before ignition.
5. Monitor the running status of the equipment in real time. Once any part is found to be operating beyond the safe range, the whole system will stop sharply, send an alarm and provide fault information.
6. The equipment starts and stops automatically under the control of PLC, which reduces the possibility of operator's misoperation.
7. Communication interface is set up inside the equipment to control the operation of peripheral devices.
8. Signal shielding measures are adopted to protect peripheral devices from electromagnetic interference during high frequency arc ignition.
 

Zhengzhou Lijia has developed a process and equipment for the inner hole tungsten carbide spraying process and equipment with a diameter of more than 100mm. As the core of the supersonic flame inner hole spraying equipment, Lijia company adopts the HV-80D kerosene supersonic flame inner hole spray gun. The inner hole spray gun adopts a global original design structure and has obtained a national invention patent, patent number: 201720177582.X. It is continuously designed and structured to innovate and optimize. This spray gun is the smallest in the world today and only uses fuel and oxygen to support combustion. The diameter of the supersonic spray gun, the front diameter of the gun body is only 80mm, and it can go deep into the narrow space within 100mm for spraying operations. At present, it has been successfully applied to spraying in narrow spaces in many industries.
This technology is mainly used for internal bores, hydraulic parts, cylinders, valve bodies, compressor bores, shell cavities, container interiors, 8-shaped holes and other working conditions with narrow internal spaces. This technology can be used to achieve inner walls with an inner diameter of 100mm or more. Spraying cemented carbide coating, the coating has high hardness, Vickers hardness above HV1100, and has the functions of wear resistance, corrosion resistance and high temperature resistance. Currently Zhengzhou Lijia is actively researching and developing spraying for smaller inner holes. It is planned to be this year In the second half of the year, a cemented carbide spraying technology with an inner diameter of 80mm or less will be developed. At present, our company undertakes a large number of internal hole tungsten carbide spraying business. Welcome friends to come to visit us.
