Supersonic Spraying System

Welcome to buy the Almac-DJ3000 supersonic spraying system independently developed and manufactured by Suzhou Almac Machinery Equipment Co., Ltd. It not only has superior performance and is at the advanced level at home and abroad, but also can realize the automation of the spraying process, making the production process more convenient.

Suzhou Almac Machinery Equipment Co., Ltd. is a Chinese manufacturer that has been deeply engaged in the research and development and manufacturing of spraying equipment for many years. It has gathered a group of professional talents and absorbed foreign technology. It was the first in China to develop touch screen controlled plasma equipment (Almac-180) (Almac-3710) (Almac-100), supersonic spraying equipment (Almac-500) (Airoco-8800) (Almac-M2plus) (Almac-M3plus), arc spraying equipment (Airoco400-Almac1000), which are widely used in the spraying industry.

The supersonic spray system uses propane, propylene and other hydrocarbon gas or liquid fuels and high-pressure oxygen to burn in a combustion chamber or special nozzle to produce a high-temperature and high-pressure flame flow (temperature can reach 3200℃), and the flame speed is as high as 15002000m/s or more. Then, the powder is sent into the flame axially or radially to produce molten or semi-molten particles, and the particles are deposited on the pretreated substrate surface at high speed (300600m/s) to form a coating.

The flame speed of the supersonic spray system is very fast, which gives the spray particles extremely high kinetic energy, allowing them to collide at high speed, making the particles in the coating more tightly connected, and having excellent wear resistance and corrosion resistance. Therefore, the supersonic spray system is widely used in aerospace, automobile manufacturing, energy, chemical industry, medical and national defense.

Powder feeder for supersonic spraying system

The Almac-DJ3000 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. Nitrogen gas is used as the powder feeding gas, and the sprayed powder is transported to the outlet of the powder feeder through the atomization vibration of the powder feeding gas. It leaves the powder feeding bucket together with the powder feeding gas and enters the spray gun. The speed of powder feeding can be adjusted by adjusting the potentiometer on the control cabinet panel.
