Open the main structure of the mobile sandblasting machine.

Open sandblasting machine must choose to have a pressure vessel certificate.

Open the main structure of the mobile sandblasting machine:

1. Sandblasting box: the pressure tank is a tank with pressure vessel produced by pressure qualified production enterprises. The general thickness is at least 6mm, and the volume size determines the thickness of the steel plate. Q235B steel plate is generally chosen. The national standard of design pressure is 0.7Mpa, and the working pressure is about 0.65Mpa. Each pressure tank is accompanied by manufacturer's follow up pressure vessel certificate. You can't use what you don't have. The size of the box can be selected according to the requirements. In general, 0.3 square sandblasting machine and M8 nozzle in the compressor air volume of 4 square case, the sand material is full, spray 30-40 minutes, cleaning area, up to 2.5 level, 10-15 square. General anticorrosion companies use this type

2. Sandblasting pipe: sandblasting pipe generally choose 1 inch 2 minutes (outer diameter 51mm, inner diameter 32mm) of sandblasting pipe, high wear resistance is required. The length of sandblasting pipe is different for each manufacturer. When purchasing, we should pay attention to the fact that the manufacturer is 5 meters and needs 6 meters. Then purchase the original 5 meters and cannot waste. There are 18 meters and 20 meters of sandblasting pipe in one roll. Most in the market are 18-meter rolls. The price of sandblasting machine is different, the import is 40 meters a roll, but the price is high, pay attention to when buying.

3. spray gun: general spray gun using double intake tungsten steel spray gun, the current boron carbide double intake spray gun long life, but no collision, fragile, high hardness, good wear resistance, most of the current use of double intake tungsten steel spray gun. Nozzles are divided into M6, M8, M10, M12 and other types, each type of air consumption is different. M6 nozzle basically only more than 2 square of air is enough.
