Main structure of open mobile sand blasting machine

1. Sandblasting box for sanding and derusting in Dalian: that is, pressure tank. It is a tank with pressure vessel produced by qualified manufacturers. Generally, the thickness is at least 6mm. The thickness of steel plate is determined according to the volume. Q235B steel plate is generally selected. The national standard of design pressure is 0.7MPa, and the working pressure is about 0.65Mpa Each pressure tank has the pressure vessel certificate followed by the manufacturer Do not use without The size of the box body is selected according to the requirements. Generally, 0.3m3 sand blasting machine is equipped with M8 nozzle. When the air volume of the air compressor is 4m3 / min, the sand material can be sprayed for 30-40 minutes, and the cleaning area can reach grade 2.5 and 10-15 square meters This model is generally used by anti-corrosion companies

2. Sand blasting pipe: generally, the sand blasting pipe of 1 inch and 2 minutes (outer diameter 51mm and inner diameter 32mm) is selected, which requires high wear resistance The length of sandblasting pipe provided by each manufacturer is different. When purchasing, note that if the manufacturer provides 5M and you need 6m, you have to buy it again. The original 5m is wasted and can not be used A roll of sand blasting pipe is 18 meters and 20 meters Most of them are 18 meter rolls on the market Prices vary. Another imported roll is 40 meters, but the price is high. Pay attention when buying

3. Sand blasting nozzle: generally, double air inlet tungsten steel nozzle is used for sand blasting nozzle. Now with boron carbide, the double air inlet nozzle has a longer service life, but it can not be bumped and is easy to break. Because of its high hardness and good wear resistance, most of them still use double air inlet tungsten steel nozzle The nozzles are divided into M6, M8, M10, M12 and other types. The air consumption of each type is different. For example, the M6 nozzle basically needs a little more than 2 square meters of gas, while the M8 nozzle needs 4 square meters of gas per minute, while the screw type and piston type of air compressor with 4 square meters of gas per minute cost about 40000 yuan and 16000 yuan respectively The price is much higher than that of sand blasting machine. Please pay attention when buying. Many users buy open sand blasting machine because the air compressor can't be brought with them and can't be used. They have to buy the air compressor again Increased trouble and burden In addition, it should be noted that in the market, there are great differences in the price of 4-party air compressors per minute, mainly in the motor. The motor is generally required to be 22KW. If it is not available, the air compressor marked with 4-party air compressors per minute may not be available Pay attention to

4. Sand control valve: there are many kinds. The key is wear resistance, and the price of consumables is low Generally, there is wear-resistant rubber in the sand control valve. If it is broken, it can be replaced with wear-resistant rubber. Generally, the sand control valve is not easy to break The ease of use of sand control valve directly affects the efficiency of sand blasting machine In addition, Cr12 with high wear resistance is used in the sand control valve In short, a sentence is easy to use and not easy to break Is the best

5. Rubber plug: there is a rubber cold on the top. Its function is to seal the gas sandblasting tank with the rubber plug upward during air inlet, so that there is high-pressure gas in the container. When adding sand, the gas is released, the rubber plug falls, and sand is added from above the rubber plug There are two kinds of cold rubber: Rubber and iron It's not easy to break
