Introduction of HV-8000

Good quality of coating! With coating having bonding strength of 90Mpa and porosity smaller than 1%, reached the international leading level,it has the test result in the domestic and foreign authoritative organization test report.

Coating powder deposition rate is high, compared with other domestic manufacturers equipment 20%, save more materials and cost, flame speed increased by more than 30%.

The mainframe equipment can be done without maintenance for 5 years, although the state stipulates that the quality is guaranteed for one year, our mainframe control system owned favorable remarks from the customers.it realizes excellent coating quality, this is unique in Domestic manufacturer.

We provide perfect after-sales service! In the length of warranty, when the equipment break down, we will contact the customer in 5 minutes, provide solution within 1 hour and site maintenance service within 24 hours, we solve the problem in 4 hours after the technician arrived at the scene, we also provide a 24-hour telephone hotline to responsible for providing technical problem solving and technical guidance.

HV-8000 has many functions and features, and its advantages are mainly reflected in the following ten aspects

  • 01 The touch screen is used as the man-machine interface to input spraying process parameters and display spraying status. The operation of the system is real-time monitoring.
  • 02 The fuel is kerosene and the combustion promoter is oxygen, which is a safer combustion mode;
  • 03 The spray gun is designed according to the principle of rocket generator. The pressure of combustion chamber reaches 150PSI, the flame flow velocity reaches more than 2000m/s, and the output power is large and can be adjusted steplessly.
  • 04 The spray gun uses radial powder feeding. This new injection method makes the powder dissolve well and distribute evenly in the whole flame, which improves the covering efficiency and coating quality.
  • 05 The system can store 8000 spray formulations, it can be directly called to the control panel when you use it.Users can easily store, invoke and modify the spraying formula through the main interface of the touch screen.
  • 06 In the system design, the temperature is located in a certain range, and to increase the speed is taken as the main objective of structural optimization. The test proved that the coating of the equipment not only has high bonding strength and coating density, but also the surface stress is compressive stress
  • 07 The master control cabinet for HV-8000 is entirely closed-loop control, modular design, high performance PLC control, safe and simple operation.
  • 08 The particles produced by combustion design at speeds of up to 1100 m/s (3,300-3,900 ft/s), significantly faster than other HVOF systems.
  • 09 Coating thickness is more than 10mm (compressive coating), micro-hardness is higher than any other HVOF system (The micro-hardness of Lijia HV series spray wc-co coating up to 1450, while other HVOF gun spray is only 900 ~ 1100)
  • 10 Lijia HV series achieved excellent high pressure HVOF coating quality, coating can reach 90MPa bonding strength.

1 D-3000 Powder feeder 1.The powder feeder is a high precision powder feeding mechanism which outputs via metering panel, uses patented feeding valve, with powder evenly output, having higher precision compared with the conveying modes of scraper type, screw and vibration, etc.;
2.Adopting small-flow nitrogen or argon gas as feeding gas, which, together with powder that arrives at powder outlet with rotation of feeding panel on the bottom, enters the spray gun, to save more gas than traditional mesohigh powder feeder.
3.Compared with the traditional double barrel type powder feeder, the metering disc type powder feeder is more fine and the powder particle size range is wider.
4.Metering panel feeder is finer than traditional dual-barrel feeder and scope of powder particle size is wider. The internationally ultromodern inclined structure is adopted to facilitate cleaning powder by overturning the barrel to pour out powder using 3 seconds.
