Compared with the dry sandblasting machine, the biggest feature is that it can well control the dust pollution during the sandblasting process and improve the working environment of the sandblasting operation.
The structure of the water sandblasting machine
1. water sandblasting machine generally constitutes a complete water sandblasting machine generally composed of five systems, namely structural system, medium power system, pipeline system, control system and auxiliary system.
2. The operating principle of the water sandblasting machine uses the grinding liquid as the feeding power of the grinding liquid, and the uniformly mixed grinding liquid (mixed liquid of abrasive and water) is transported to the spray gun through the grinding liquid pump.
The working principle of water sandblasting machine:
As the accelerating 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, and sprayed to the outside of the processing to express the expected processing intent. In the liquid sandblasting machine, the grinding fluid pump is the power supply, and the compressed air is the acceleration power.
The physical treatment method of sandblasting machine and the advantages of sandblasting technology
Sandblasting machine sandblasting method electroplating pretreatment, the concept of sandblasting machine is to grind the surface of pneumatic sand material. The sandblasting and electroplating process occupies a pivotal position. The main function is to remove impurities and oxide scale on the surface of the workpiece, and the surface area is increased. , Improve the adhesion of the coating and improve the quality of the sandblasted coating; the machine can also dissipate the residual stress in the structure, realize the surface hardening of the workpiece, improve the surface resistance to plastic deformation and fracture, and the surface compressive stress of the workpiece, and increase its fatigue Strength; damage surface defects and reduce processing workpieces, reduce stress concentration, etc.
Advantages of sand blaster machine:
1. It is processed by physical reaction and sandblasting, the basic metal parts are not damaged, and the dimensional accuracy will not change;
2. The surface of the workpiece is not contaminated, and the abrasive will not react with the material part.
3. The sand blaster machine can easily handle difficult-to-machine parts such as grooves and recesses, and various grit abrasive tools can be used.
4. The processing cost is greatly reduced, which is mainly reflected in the improvement of the work efficiency of the sandblasting machine, which can meet various surface processing requirements.
5. Low energy consumption and cost saving.
6. The sand blaster machine does not pollute the environment and saves the cost of environmental treatment.
