High Pressure Seamless/CNG cylinder Inner Sand Blasting Machine Outer Shot Blasting Machine~
Product Introduction
1.Cylinder internal sand blasting machine
Sandblasting is a method of using compressed air to blow out quartz sand at high speed to clean the surface of parts.The main function of sandblasting is to remove rust and scale on the surface, such as parts after heat treatment.Sandblasted sand, which is just river sand, is no different from that used in construction, except that the sandblasted sand is screened, contains less mud, and has a particle size specification. Of course, some industries are also different. For example, the shot blasting in the shipbuilding industry uses real steel shot, and the sand blasting uses metal ore (not river sand-quartz sand).
1)During the sandblasting process, clean up the attachments, welding slag, grease and other dirt on the metal surface;
2) During the sandblasting process, the air temperature should also be kept below 85 degrees;
3) The compressed air used in the sandblasting process needs to be treated by a cooling device and an oil-water separator to ensure that the compressed air is dry and oil-free;
Fourth, the best choice of abrasive is ceramic sand and iron sand. The abrasive is required to be angular, clean, dry and free of oil.
2.External shot blasting machine
The shot blasting machine refers to the casting equipment that uses the high-speed projectile thrown by the shot blasting machine to clean or strengthen the surface of the casting. The shot blasting machine can shake out, de-core and clean the castings at the same time. In some areas, it is also called a sandblaster and a sandblaster.
1) Shot blasting is to use a high-speed rotating impeller to throw small steel shot or small iron shot out to hit the surface of the part at high speed, so the oxide layer on the surface of the part can be removed.
2) Shot blasting has many functions and functions. It not only removes rust and oxide scale, but also improves surface roughness, removes machining burrs, eliminates internal stress of parts, reduces deformation of parts after heat treatment, and improves surface wear resistance of parts. pressure capacity, etc.
3) The steel shot and iron shot used in shot blasting are not actually shot in the real sense. To be precise, it is a small steel wire or a small steel rod, which only looks like a ball after a period of use.
