Type 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.
First, the pressurized sand blasting gun is divided into two types: 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 eight small openings in the middle, which play the role of secondary air intake. Thereby, the efficiency of the blasting gun can be improved. In terms of materials, sand blasting guns are divided into boron carbide, alloy steel, tungsten carbide, iron and so on. The most durable is a boron carbide sandblasting gun.
Life is generally 500-700 hours. The price is generally between 300-500. Secondly, the service life of tungsten carbide and alloy steel is generally 300-400 hours, and the price is generally between 200-300. Iron can only be used for 10 hours, and few people use it now.
Second, the negative pressure sand blasting gun is shown in the figure. Negative pressure sand blasting gunThe negative pressure sand blasting gun is also the sand blasting gun used for box type sand blasting machines. It 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. There is no switch on this blasting gun, and an additional pressure switch is required. There is also a pistol sandblasting gun with a switch on the gun body. In other words, the Kellogg sand blasting gun has a price of about 200-300 yuan. The component nozzle inside is easier
Damaged and can be replaced. Its material is divided into two kinds of boron carbide and tungsten steel. Among them, boron carbide has a longer service life than tungsten steel. Generally, a boron carbide nozzle is selected for replacement. The price is 120-180 yuan. Depending on its specifications. The choice of the two guns is based on the blasting machine that has been purchased, and the selection of the blasting machine is based on the process.
