Other factors affecting the quality of shot blasting machine
The blasting quality of the shot blasting machine is affected by the opening angle position of the directional sleeve (the opening angle position of the directional sleeve of the shot blasting machine can be changed. In the actual work process, according to different cleaning surfaces, it can be based on The position of the opening angle is purposely adjusted, and the position of the opening angle is determined through continuous testing. It is also affected by many other factors: the size and shape of the projectile particles of the shot blasting machine, the size and direction of the projectile throwing speed, and the shot blasting The walking speed of the machine is actually determined by the opening angle of the directional sleeve.
From a practical point of view, sometimes a shot blasting machine is needed to increase the roughness of the surface being cleaned, such as road roughening, tunnel maintenance, and sometimes a shot blasting machine is needed to reduce the roughness of the surface being cleaned, such as shot blasting to increase color , Derusting of steel plate, etc. Different parameters need to be selected according to different situations.According to experience, when the projectile throwing speed is above 50m / s, the general cleaning effect can be achieved, such as derusting of the steel plate, the projectile speed of the shot blasting machine should be above 60m / s, The airport runway degumming requires that the projectile speed should be above 70m / s; when the throwing angle is selected between 30b-60b, the throwing effect is better.
