Basic functions of sand blasting gun


There are more types of sand blasting guns than schools, and they are generally divided into two types of pressure and negative pressure.
In terms of materials, sand blasting guns are divided into boron carbide, alloy steel, tungsten carbide, and iron. The most durable is a boron carbide sand blasting gun with a typical service life of 500-700 hours. The price is generally between 300-500.
There are two types of pressure sandblasting guns: single inlet and double inlet.
The single inlet is a straight tube with a Venturi structure.
The double air intake is divided into two sections, with 8 small openings in the middle, which play the role of secondary air intake. Thereby, the efficiency of the blasting gun can be improved.
Negative pressure sand blasting gun, which is also used for box type sand blasting machine, has an inlet port and a sand inlet port.
The negative pressure generated by the gas in the sand blasting gun sucks the sand material into the sand blasting and is then driven out of the sand blasting gun by the gas.
Distinguish from the shape of the gun body: There are many types such as A-type, B-type, C-type, K-type pneumatic Carle-type spray guns, engraving spray guns with canister spray guns, etc., regardless of how the spray gun is fixed on the frame, various types of spray guns are universal .
Distinguish from the docking method of the spray gun and the sand tube: there are direct insertion type (the sand tube is directly inserted into the spray gun and locked with screws) and ribbed spray gun using the sand core (insert the sand core into the sand tube and lock it with a hose clamp)
The blast gun is distinguished from the diameter of the interface between the sand core and the air core: the air core is distinguished by 10mm (c-type gun) and 13mm (A-type B-type gun, etc.), and the sand core is generally 13mm;
