Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece has a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved. Therefore, the fatigue resistance of the workpiece is improved, and it and the coating are increased. The adhesion between them prolongs the durability of the coating film, which is also conducive to the leveling and decoration of the coating, removes impurities, variegations and oxide layers on the surface, while roughening the surface of the medium, eliminating residual stress on the workpiece and improving the substrate The role of surface hardness.
Suction type 1. General composition Sand blasting machine A complete suction dry blasting machine is generally composed of six systems, namely the structural system, medium power system, piping system, dust removal system, control system and auxiliary system.
2. The working principle is that the suction type dry blasting machine is driven by compressed air, and the negative pressure formed in the spray gun through the high-speed movement of the airflow. The abrasive is sucked into the spray gun through the sand conveying pipe and ejected through the nozzle to be sprayed onto the surface to be processed. To achieve the intended processing purpose. In the suction-type dry blasting machine, compressed air is both the supply power and the acceleration power of the jet.
Press-in type For the press-in type dry blasting machine, we focus on the press-in type blasting work unit, which is a basic work unit composed of a pressure tank and a spray gun.
1. General composition A complete press-in dry blasting machine working unit is generally composed of four systems, namely the pressure tank, the medium power system, the piping system, and the control system.
2. The working principle of the press-in dry blasting machine The press-in dry blasting machine is driven by compressed air and uses the working pressure established in the pressure tank by the compressed air to press the abrasive through the sand outlet valve into the sand conveying pipe and Ejected through a nozzle and sprayed onto the surface to be processed to achieve the intended processing purpose. In a press-in dry blasting machine, compressed air is both the supply power and the acceleration power of the jet.
