Shot blasting wheel
The shot blasting wheel is the core component of the shot blasting machine. The shot material is thrown out by centrifugal force to hit the surface. The shot blasting wheel is installed in the shot blasting room with a replaceable protective liner. The shot blasting wheel is driven by a shot blasting motor.
In the center of the shot blasting wheel is the distribution wheel (4 columns), which distributes the shot material entering the blade. At the top is the directional sleeve, which needs to be carefully installed to control the direction of the shot material.
Directional sleeve
Adjustment of the directional sleeve and adjustment of the shot blasting marks
In order to obtain a satisfactory shot blasting effect, the adjustment of the shot blasting marks is very important.
① The direction of rotation of the shot blasting wheel must be correct;
② The worn shot blasting wheel and components must be replaced;
③ The diameter of the shot must meet the requirements of the machine (maximum 1.8mm);
④ The direction of the opening on the directional sleeve determines the direction of the shot blasting, which directly affects the shot blasting marks;
⑤ The position of the directional sleeve must be adjusted every time the shot blasting assembly is replaced;
⑥ Setting of the directional sleeve: When adjusting the directional sleeve, loosen the clamping device and select the directional sleeve. There is a notch on the edge of the directional sleeve to indicate the opening position of the directional sleeve. Shots of different specifications have different weights, so they have different throwing directions and accelerations, so different shot materials cannot be mixed.
How to replace the liner
1. Remove the bolts and remove the cover;
2. Loosen the bolts to take out the left and right liner from the bottom;
3. After the left and right liner are removed, the top plate can be taken out from the bottom;
4. The center liner can be taken out from the front of the machine by loosening the bolts at the rear of the shot blasting chamber;
5. Loosen the bolts to take out the side liner from the bottom;
6. Loosen the bolts to take out the upper and lower liner from the bottom.
