High Pressure – High Velocity Oxy-Liquid Fuel (HP-HVOLF) Spray System
HP-HVOLF COATING PROCESS
The SE-JET 5000 uses an elegantly simple and effective desing to produce Hight pressure – High Velocity Liquid – Oxy Fuel Coating of superior quality
The Coating benefits inlcudes:
- High coating density (*1% porosity)
- High coating hardness (>72 HRC)
- Coating thickness up to 12mm (depends on powders)
- Smoother as-sprayed finish
- High bond strength (>1000 PSI)
In addition to the outstanding coating quality the SE-JET 5000 delivers spray rates four times higher than typical HVOF Systems. This dramatic increase in spray rate and productivity places the SE-JET 5000 system in a new category of HVOF equipment.
Fuel (kerosene) and oxygen mix and then atomized after passing through orifices into a combustion chamber thereby creating stable, clean and uniform combustion. The combustion chamber pressure is monitored to assure proper combustion mode and constant pressure.
The Particle velocity is directly related to chamber pressure. The unique cover / diverging exit nozzle of the combustion chamber is sized and shaped to create a supersonic jet that maintains a low-pressure area where the powder is radially injected through multiple ports. The SE-JET 5000 HVOF Gun uses a radial powder injection system as opposed to the axial systems of others HVOFs
The radial injection has several benefits:
- Less powder feed pressure is required because the powder injected into a low pressure area created by the converging / diverging nozzles.
- Powder velocity and temperatures are evenly distributed across the spray.
Once injected the powder mixes with the gas and is accelerated to near maximum velocity as leaves the barrel and is carried along at constant velocity to impact the substrate.
