Super air knife   

    The super air knife is mainly used for dust removal and liquid removal. Compared with traditional air rods and strips, it can save 70% of air consumption. It uses a large amount of compressed air.

The air knife is a very suitable product for various applications, such as dust removal, water removal, drying and cooling. Super air knives can be divided into stainless steel air knives according to material

Knife, aluminum alloy air knife and plastic air knife. Stainless steel air knife is mainly used in corrosion-resistant occasions. Aluminum alloy air knife has good versatility. Plastic air knife is mainly used.

In situations containing acidic cleaning fluid or corrosive plating fluid.

    After the compressed air enters the air knife, it is blown out at high speed as an air flow sheet with a thickness of only 0.05 mm. Through the principle of Costa effect and the special air knife

With its unique geometric shape, this sheet air curtain can divert up to 30-40 times the ambient air, forming a thin, high-strength, large-flow impact air curtain.

Ruitian Mechanical and Electrical Technology's Leitz air knives are divided into two types: standard air knives and super air knives in terms of working modes . The air curtain of the standard air knife is deflected 90 degrees and then blown out;

The air curtain of the wind knife blows out horizontally. The Costa effect, also called the Coanda effect, refers to when there is a surface between the fluid (water flow or air flow) and the surface of the object it flows through.

When friction occurs, the flow of fluid slows down. As long as the curvature of the object surface is not too large, the fluid will leave its original flow direction and instead adhere to the protruding surface.

The surface of the object flows, and finally a strange phenomenon occurs where the fluid is adsorbed and flows on the surface of the object. You can do a small experiment like this: turn on the water dragon

head, release a small stream of water, and place the back of the spoon next to the flow. The water will be attracted and flow to the back of the spoon. This is due to the Coanda effect

As a result, when the water flow attaches to the spoon, the Coanda effect water flow always flows on the convex surface of the spoon.
