What is sandblasting machine?

 A sandblasting machine is a machine that uses compressed air as power to form a high-speed jet beam to spray the spray material on the surface of the workpiece to be processed at a high speed, so that the mechanical properties of the outer surface of the workpiece surface are changed.

The working principle of sand blaster machine:

Due to the impact and cutting action of abrasives on the surface of the workpiece, the sand blaster machine obtains a certain degree of cleanliness and different roughness on the surface of the workpiece, and improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece and increasing it The adhesion between the coating and the coating extends the durability of the coating. The small sandblasting machine is also conducive to the leveling and decoration of the coating. The residual stress on the surface of the substrate and the effect of improving the surface hardness of the substrate. Suction dry automatic sandblasting machine

1. General composition automatic sandblasting machine

A complete suction dry sandblasting machine generally consists of six systems, namely structural system, medium power system, pipeline system, dust removal system, control system and auxiliary system.　　

2. Working principle The portable sand blasting machine is powered 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 pipe and ejected through the nozzle, and sprayed to the surface to be processed to achieve the expected Processing items. In the suction dry sandblasting machine, compressed air is both the feed power and the acceleration power of the jet.

Press-in dry sandblasting machine

For the press-in dry sandblasting machine, we focus on the press-in sandblasting work unit, which is the basic work unit composed of a pressure tank and a spray gun.　　

1. General composition 　　 A complete sand blaster machine working unit is generally composed of four systems, namely pressure tank, medium power system, piping system, and control system.

2. The working principle of the press-in dry sand blasting machine The press-in dry sand blasting machine is powered by compressed air, through the working pressure established in the pressure tank by the compressed air, the abrasive is pressed into the sand pipe through the sand valve and passed through the nozzle Injection, spray to the surface to be processed to achieve the desired processing goal. In the portable sand blasting machine, compressed air is both the feed power and the acceleration power of the jet.

water sandblasting machine

Compared with the dry sandblasting machine, the biggest feature of the water sandblasting machine is that it can well control dust pollution during the sandblasting process and improve the working environment of the sandblasting operation. The structure and working principle of the wet sandblasting machine will be introduced in detail below.　　

1. General composition 　　 A complete wet sandblasting machine is generally composed of five systems, namely structural system, medium power system, piping system, control system, and auxiliary system.　　

2. Working principle 　　 water sandblasting machine uses the grinding liquid pump as the feeding power of the grinding liquid, and the uniformly stirred grinding liquid (mixed liquid of abrasive and water) is delivered to the spray gun through the grinding liquid pump. As the acceleration power of the grinding liquid, compressed air enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding liquid entering the spray gun and is ejected through the nozzle to achieve the expected processing purpose. In the wet sand blasting machine, the grinding fluid pump is the power supply, and the compressed air is the acceleration power.
