Application skills of shot blasting cleaning machine

Shot blasting is to use the high-speed rotating impeller to throw out small steel shot or small iron shot and hit the surface of the part at high speed, so the oxide layer on the surface of the part can be removed. At the same time, steel shot or iron shot impacts the part surface at high speed, resulting in lattice distortion and deformation of the part surface and increasing the surface hardness. It is a method to clean the part surface. Shot blasting is often used to clean the casting surface or strengthen the part surface.

Usage skills of shot blasting machine:

1. In the process of shot blasting cleaning machine, more workpieces should be placed in the shot blasting area as much as possible, which can not only improve the cleaning efficiency, but also reduce the wear of guard plate and increase its service life.

2. When the workpiece cannot be increased, the orientation sleeve shall be adjusted to make the shot steel shot on the workpiece as much as possible, which can also increase the service life of the guard plate and reduce its wear.

3. ① the dust removal system shall adjust the gates of the branch pipe to make the wind distribution reasonable and enhance the dust removal effect. ② The dust collector shall ensure regular ash cleaning.

Generally, Dalian sand blasting and shot blasting processing is used for workpieces with regular shape. Several polishing heads are up, down, left and right together, with high efficiency and little pollution. Shot blasting and sand blasting are widely used in the repair and shipbuilding industry. However, whether shot blasting or sand blasting, compressed air is used. Of course, it is not shot blasting that requires a high-speed rotating impeller. In the repair and shipbuilding industry, shot blasting (small steel shot) is generally used in steel plate pretreatment (rust removal before coating); Sand blasting (mineral sand used in repair and shipbuilding) is mostly used in formed ships or sections to remove the old paint and rust on the steel plate and repaint it. In the repair and shipbuilding industry, the main function of shot blasting and sand blasting is to increase the adhesion of steel plate coating paint.

In fact, the casting cleaning is not just shot blasting. For large parts, the drum sand cleaning is generally carried out first, that is, the riser of the casting is cut off and then rolled in the drum. The parts collide with each other in the drum, and most of the sand on the surface is cleaned first, and then shot blasting or shot blasting is carried out.
