Air compressor industry application – sandblasting industry
The sandblasting process is widely used. Almost every kind of utensils in our life need sandblasting in the process of strengthening or beautifying in the production process: stainless steel faucets, lampshades, kitchen utensils, car axles, airplanes and so on.
The sandblasting machine uses compressed air to transport powdery particles (diameter 1—4mm) from one place to another. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, and microscopically cut or impact the surface of the work piece to improve the surface quality of the object. In order to realize the rust removal, paint removal, surface impurity removal, surface strengthening and various decorative treatments of the work piece.
Sandblasting machines can be divided into general pressure sandblasting machines, pressurized sandblasting machines, and high-pressure sandblasting machines in terms of sandblasting efficiency and strength. The air compressor connected to the sandblasting machine generally has a pressure of 0.8Mpa, and then selects the appropriate air compressor according to the size of the air source required by the sandblasting machine.
The general pressure sandblasting machine is the siphon sandblasting machine. Compared with the other two types of sandblasting machines, the sandblasting efficiency of a single gun is lower than that of the pressurized and high-pressure sandblasting machines. Each gun needs to be equipped with an air compressor with an air output of at least 1 cubic meter per minute, that is, an air compressor with at least 7.5KW.
Both the pressurized sandblasting machine and the high pressure sandblasting machine belong to the pressure feeding sandblasting machine. The sandblasting efficiency of a single gun is lower than that of the high pressure type. Each gun on the pressurized sandblasting machine needs to be equipped with The best air compressor has a gas output of at least 2 cubic meters per minute, which is a 15KW air compressor.
Each gun on the high-pressure sandblasting machine needs to be equipped with an air compressor with an air output of at least 3 cubic meters per minute, which is a 22KW air compressor.
In general, the bigger the air compressor, the better. If you consider the cost, you can refer to the above data for selection. The air compressor connected to the sandblasting machine also needs to be equipped with an air tank and air dryer. The air tank is used to store the air generated by the air compressor to ensure the stability of the air source. The dryer is used to dry the moisture in the air to ensure The air is dry when it reaches the sandblasting machine, which also reduces the problem of sand plugging caused by sand agglomeration.
