SX-6000 HVOF supersonic spray tungsten carbide coating Manual operation

MFC SX- 9000 Auto / FM SX-8000 Economical / M SX-6000 Manual operation

SX-9000 /SX-8000/ SX-6000 supersonic flame spraying is a new type of HVOF system, its basic principle is to atomize kerosene through oxygen to form a combustible mixture into the combustion chamber, the ignition system will ignite it to produce high temperature and high pressure flame, and accelerate the formation of high temperature and high pressure supersonic flame flow through the pull-valve nozzle. Powder feeder will send powder materials from the low pressure area into the flame flow. After heating acceleration, it is sprayed onto the surface of the workpiece to form a high-quality coating. spraying system is a spraying equipment developed on the basis of the introduction, digestion and absorption of foreign advanced equipment and technology, and has different significant characteristics from other HVOF.

Safe operation: HVOF runs on kerosene or similar fuels. For maximum performance, other HVOF systems typically use hydrogen, a potentially dangerous gas. But HVOF does not need this expensive, difficult-to-process gas to get the best performance. Kerosene is a safe fuel widely used in millions of homes, so sx-9000, SX-8000,SX-6000 are the safest choices for HP/HVOF coatings

Coating systems provide high quality coating services for industries including steel, Marine, aerospace, carton machinery, paper machinery, plastics machinery, petrochemical machinery and general machinery. Some of the coatings of the sx-8000 have become standard coatings for various types of rollers in the steel industry, corrugated rollers in carton machinery, and large diesel engine intake and exhaust valve stems.

SX-8000 Supersonic Flame spraying Features:

1. The fuel used is kerosene and the combustion gas is oxygen, which is a safer combustion mode.

2, the flame flow speed is high, the output power is large, and the gas and fuel flow can be adjusted arbitrarily.

3, the spray gun uses radial powder feeding, this new injection method makes the powder can be better deepened and evenly distributed in the entire flame, improve the covering efficiency and coating quality.

4. The temperature range is located in a certain range in the system design, and the increase of speed is regarded as the main objective function of structural optimization. X-ray diffraction test proves that the prepared coating not only has high bonding strength, high coating density, but also the surface stress is compressive stress.

5, modular design, control terminal +PLC control, safe and easy to operate.

6, combustion design particle speeds of 1100 m/s (3,300 to 3,900 ft/s), significantly faster than other HVOF spray systems;

7, the coating thickness is greater than 1/2 inch (compressive stress layer). The microhardness of the coating is higher than that of any other technology or system (WC-Co), the hardness is 1450, while the microhardness of other gas HVOF spray guns is only 1100 ~ 900;

8. The sx-8000 supersonic flame spraying equipment achieves excellent high pressure HVOF spraying coating quality, and the bonding strength of the coating can reach 90 mpa.

The equipment includes: Atomic energy control cabinet; b powder feeder; C-spray gun; d cooling system; Connection of oil storage tanks and pipelines.

SX-6000 HVOF equipment Site preparation:

1.main power switch + propane + nitrogen + liquid oxygen ( for HVOF advanced plasma spray gun）

A, nitrogen: nitrogen for powder feeding, common nitrogen cylinder, nitrogen pressure 0.8mpa

B, propane: propane for spray gun ignition, ordinary propane cylinder, propane pressure 0.8MPa

C: liquid oxygen: liquid oxygen gas and kerosene are added together to produce a flame.

2.Ordinary industrial kerosene or aviation kerosene should be clean and free from impurities. Fuel interface can be directly connected to the oil drum and tilt the oil drum. The oil drum should be equipped with 10um fuel filter and re-supply equipment.

3.  Sprayed All kinds of ceramic coatings Including:Tungsten carbide, nickel-chromium carbide, nickel-chromium alloy, etc. / Carbide powder :WC, TiC, Cr3C2, etc. / cermet powder: WC-CO, CR3C2-NICR, etc

SX-6000 HVOF spraying equipment is an improved spraying equipment based on the introduction/digestion/absorption of foreign advanced equipment and technology.

Compared with other HVOF, there are eight distinct and significant characteristics:

1. Kerosene is the fuel and oxygen is the combustion aid. This is a relatively safe way to burn.

2. The gun is designed according to the principle of rocket engine. Chamber pressure up to 150PSI and speed up to 150PSI

Flame greater than 2000m/s. Large output power, no level adjustable.

3. Powder gun adopts radial feeding method. This new injection method allows the powder to be better melted and evenly distributed throughout the flame,Improve the coating efficiency and quality;

 4. A certain temperature range is determined by system design, and speed increase is the main objective function of structure optimization. X-ray diffraction test shows that the coating not only has high strength and high density, but also has surface stress.

5. Modular design, high-performance PLC control, easy to operate

6. The combustion design has particle velocities of up to 1100 M/S(3,300-3,900 ft/s), significantly faster than other HVOF systems.

7. Coating thickness greater than 1/2 inch (compressive stress coating). The microhardness of the coating is higher than that of any other HVOF system (WC-Co), with a hardness of 1450, while the microhardness of other gas HVOF guns is only 1100 ~ 900;

8. The SX-8000 supersonic flame spraying equipment achieves excellent high pressure HVOF coating quality, and the coating can reach a binding strength of 90MPa.

The equipment contains:

 1-control system 2-intelligent powder feeder;3-spray gun; 4-water chiller;5-the oil storage tank and piping connection.
