The number of blasting guns is customized according to the original design of the blasting machine
1. Selection of sand material. Generally, sand with good quality is selected, and brown corundum, white corundum, green silicon carbide, glass beads, resin sand, steel sand, and steel shot are usually used. The specific sand used should be selected according to the actual process requirements.
2. There are wear holes in the sand nozzle, gas nozzle and gun body. It should be replaced in time to avoid causing greater wear. When the caliber of the nozzle is increased to 30%, it should be replaced in time. So as not to waste gas.
3. The hardness and shape of each sand are different. Generally speaking, the larger the hardness, the more abrasive the sandstone is, the faster the damage to the spray gun, so when you encounter similar sand, you should check the caliber of the spray gun and nozzle, and check it every 7 days. Generally, the hardness is called small sand. The shape of the sand is round. The inspection cycle can be checked every 15 days.
4. The boron carbide nozzle is introduced to replace which part is worn when the blast gun is replaced. Do not replace the whole set, so as to avoid wasting costs. The number of spray guns of the sand blasting machine is customized according to the original design of the sand blasting machine . It consists of nozzles, sand nozzles, gas nozzles, gun bodies, and plastic sleeves. The nozzle ultimately determines the efficiency of the sand blast and the air consumption of the air compressor. The greater the number of guns, the faster the processing efficiency, and conversely, the higher the air source using an air compressor. The nozzle of a general pressure sand blasting machine has a gas consumption of 0.8 cubic meters per minute at 8mm.
