Supersonic Spraying Equipment is a cutting-edge technology that utilizes high-velocity gas streams to deposit materials onto a substrate surface. Here's an overview of this advanced equipment.Basic Principle:Supersonic spraying equipment operates on the principle of accelerating a mixture of fuel (such as kerosene) and oxygen through a specially designed nozzle.
This mixture is fully atomized and injected into a combustion chamber where it undergoes high temperature and pressure. After ignition, a supersonic jet flow is created, which carries powdered materials into the flame stream. The powdered materials are heated and accelerated before being sprayed onto the workpiece surface, forming a high-quality coating.
Fuel Type and Combustion Mode: The equipment uses kerosene as fuel and oxygen as the accelerant, resulting in a relatively safe combustion mode.
Gun Structure and Performance: The spray gun is designed based on rocket engine principles, with a chamber pressure of 150 psi and a flame flow rate exceeding 2000 m/s. The output power can be adjusted to meet different coating requirements.
Powder Feeding System: The radial powder feeding method ensures that the powder is evenly distributed throughout the flames, improving coating efficiency and quality.
System Design: The system is optimized for structural performance within a specific temperature range, with speed as the primary objective function. X-ray diffraction tests have proven that the coatings produced by this equipment have high bonding strength, density, and compressive surface stress.
Modular Design and PLC Control: The modular design allows for easy maintenance and upgrades. The high-performance PLC control system ensures safe and simple operation.
Particle Velocity and Coating Quality: The particles in the supersonic jet flow reach speeds of up to 1100 m/s, significantly faster than other HVOF (High Velocity Oxygen Fuel) systems. This results in coating layers with thicknesses exceeding 1/2 inch and microhardness values higher than any other HVOF system.
Supersonic spraying equipment has a wide range of applications across various industries:
Steel and Shipbuilding: Coatings for various rollers and components in the steel and shipbuilding industries.
Aerospace: Manufacturing high-temperature alloy parts with anti-oxidation layers to improve heat resistance.
Machinery: Coatings for carton, paper, plastic, and petrochemical machinery to extend service life.
General Machinery: Providing quality services to the coating industry in general machinery.
In addition to its practical applications, supersonic spraying equipment has also found its way into the artistic realm. Artists utilize its unique properties to create stunning artworks by spraying different materials and paints onto canvases, achieving rich textures and depth.
