The introduction of Tungsten carbide coating machine/Hvof Thermal Spray Service The HVOF (High Velocity Oxygen Fuel) Thermal Spray Process is basically the same as the combustion powder spray process (LVOF) except that this process has been developed to produce extremely high spray velocity. There are a number of HVOF guns which use different methods to achieve high velocity spraying. One method is basically a high pressure water cooled HVOF combustion chamber and long nozzle. Fuel (kerosene, acetylene, propylene and hydrogen) and oxygen are fed into the chamber, combustion produces a hot high pressure flame which is forced down a nozzle increasing its velocity. Powder may be fed axially into the HVOF combustion chamber under high pressure or fed through the side of laval type nozzle where the pressure is lower. Another method uses a simpler system of a high pressure combustion nozzle and air cap. Fuel gas (propane, propylene or hydrogen) and oxygen are supplied at high pressure, combustion occurs outside the nozzle but within an air cap supplied with compressed air. The compressed air pinches and accelerates the flame and acts as a coolant for the HVOF gun. Powder is fed at high pressure axially from the centre of the nozzle.
Tungsten carbide coating equipment,SX-5000 HVOF spray equipment Our HVOF system SX-5000 consists of control cabinet, powder feeding machine, cooling system, spray gun and pipeline system. It’s a compact equipment with the traits of easy-operating, stable working performance, low fuel consumption and high-quality coating.
A.SX-5000 control cabinet of Tungsten carbide coating machine/Hvof Thermal Spray Service
The control cabinet is equivalent to advanced foreign control system in designing. It’s easy to operate, with the feature of automation-operation during spraying process. You can monitor the system and control the spray gun real-time, and react with system breakdown immediately.
Parameters of SX-5000 control cabinet
Input power supply
Single phase AC220V,50Hz
Fuel gas and pressure
B.SX-5000 powder feeding machine of Tungsten carbide coating machine/Hvof Thermal Spray Service
Powder feeding machine is used to save spraying powder and send them to the spray gun according to technological requirements. It uses nitrogen as feeding gas, and the powder is pulverized into atomization. Then the pulverized powder and nitrogen gas together are sent into spray gun from powder tube. You can use the potentiometer on control cabinet panel to regulate the velocity of feeding powder.
C.SX-5000 cooling system of Tungsten carbide coating machine/Hvof Thermal Spray Service
D.SX-5000 spray gun of Tungsten carbide coating machine/Hvof Thermal Spray Service
The spray gun can be operated by manual or fixed to machine hand. It uses oxygen and propane as working gas, and the spraying particles can gain a velocity of ≥450m/s. It can work steadily in a long time.
