SX-9000 Supersonic Spraying Equipment

The SX-9000 supersonic flame spraying system is a new type of HVOF system. Its basic principle involves atomizing kerosene with oxygen to form a combustible mixture, which is then fed into the combustion chamber. After being ignited by the ignition system, the mixture produces a high-temperature, high-pressure flame. This flame is accelerated through a Laval nozzle, forming a supersonic flame jet at high temperature and pressure. A powder feeder delivers the powdered material from a low-pressure zone into the flame jet, where it is heated and accelerated before being sprayed onto the workpiece surface to form a high-quality coating.

Introduction to the SX-9000 Supersonic Flame Spraying Equipment
The SX-9000 supersonic flame spraying system is a new type of HVOF system.

After being ignited by the ignition system, the mixture produces a high-temperature, high-pressure flame.

Composition of the SX-9000 High-Speed (Supersonic) Flame Spraying Equipment

by ① Spray gun, ② Powder feeder, ③ Control system, ④ Heat exchange system, and ⑤ various pipelines—these five components make up a compact spraying device (which can be equipped with one imported JP5000 spray gun).

1. SX-9000 Fuel Supersonic Control Cabinet
(Main control system with Siemens) The PLC touch screen, equipped with a Deltec proton flowmeter imported from the U.S., allows for precise parameter adjustment and enables flexible programming according to coating requirements, featuring a high degree of automation. The control cabinet serves as the central hub of the supersonic spraying system; leveraging cutting-edge technology, it provides fully automated control over the entire spraying process. The fuel-powered supersonic spraying system boasts advanced performance comparable to similar foreign products, offering superior operational efficiency and ease of use. The control cabinet features a PLC-based touch-screen control terminal that integrates operation, settings, help functions, display, process monitoring, and fault alarm systems into a single unit, simplifying panel design and making the system both user-friendly and intuitively easy to operate.

2. SX-9000 Supersonic Fuel Powder Feeder
(The newly upgraded powder feeder comes with Siemens.) The PLC touch screen, along with functions such as powder feed rate, number of cycles, and coating thickness, is linked to the main control system for flexible programming and boasts a high degree of automation.
The SX-9000 fuel-supplied supersonic high-speed flame spraying powder feeder is a device used to store spraying powder and deliver it to the spray gun according to process requirements. It uses nitrogen as the powder-feeding gas; the spraying powder is atomized and vibrated by the powder-feeding gas, enabling it to be conveyed to the outlet of the feeder and then exit the feeder along with the powder-feeding gas, entering the spray gun. By adjusting the potentiometer on the control cabinet panel, the speed of powder feeding can be regulated.

Superiority of the SX-9000 Fuel (HVOF) Supersonic Spraying Equipment:

1. This is a relatively safe combustion mode that uses kerosene as the fuel and oxygen as the oxidizing gas.
2. The flame jet has a high velocity, delivers high output power, and allows for arbitrary adjustment of gas and fuel flow rates.
3. The spray gun employs radial powder feeding. This new injection method enables the powder to penetrate more effectively and distribute uniformly throughout the flame, thereby improving coverage efficiency and coating quality.
4. The system design sets the temperature range within a specific interval and takes increasing the speed as the primary objective function for structural optimization. X-ray diffraction tests have confirmed that the coatings produced not only exhibit high bonding strength and high density, but also feature compressive stress in the surface layer.

5. Modular design, featuring a control terminal plus PLC control for safe and easy operation.
