Pressurized sandblasting gun and negative pressure sandblasting gun

Pressurized sandblasting gun

Pressurized sandblasting gun is divided into single air inlet and double air inlet.
The single inlet air is a straight tube with a venturi structure.
The double air inlet is divided into two sections, with eight small openings in the middle, which plays the role of secondary air inlet. This can improve the efficiency of the sandblasting gun.

Negative pressure sandblasting gun

The negative pressure sandblasting gun is also the sandblasting gun used by the box-type sandblasting machine, which has an air inlet port and a sand inlet port.
The sand material is sucked into the sandblasting gun by the negative pressure generated by the gas in the sandblasting gun and then driven out of the sandblasting gun by the gas.
There is no switch on this sandblasting gun, and additional pressurization switch is required.
There is also a pistol sandblasting gun with a switch on the gun body. The price of the Kale sandblast gun is about 200-300 yuan.
The parts and nozzles inside are easy to be damaged and can be replaced. Its material is divided into boron carbide and tungsten steel. The service life of boron carbide is longer than that of tungsten steel. Generally, boron carbide nozzle is selected for replacement. The price is 120-180 yuan. It depends on its specification.
The selection of the two guns depends on the sandblasting machine you have purchased, and the selection of sandblasting machine depends on the process.
