Many friends bought the shot blasting machine cleaning effect is not ideal how to do? We do not consider the quality problems of the shot blasting machine manufacturers, from the impact of the five factors to consider the cleaning effect of the shot blasting machine, according to the following five points to find a solution to the cleaning effect of the shot blasting machine.

First, the size of the shot blasting: the larger the steel shot (shot blasting), the greater the impact kinetic energy, the greater the strength of the shot blasting, but the coverage of the steel shot is reduced. Therefore, while ensuring the strength of shot blasting, smaller shot blasting should be selected as far as possible. In addition, the size of the shot peening is also limited by the shape of the part. When there is a groove on the part, the diameter of the shot should be less than half the radius of the circle in the groove. The pellet size is usually selected between 6 and 50 mesh.

Second, the hardness of shot blasting: when the hardness of shot blasting is higher than the hardness of the part, the change of its hardness value does not affect the strength of shot blasting; When the shot blasting is softer than the part, if the hardness value of the shot blasting decreases, the shot blasting strength also decreases.

Third, the speed of shot blasting: when the shot blasting speed increases, the shot blasting strength also increases, but when the speed is too high, the amount of shot blasting damage also increases.

Fourth, the projectile Angle: when the shot blasting jet is vertical to the surface to be sprayed, the shot blasting strength * (this word advertising law prohibits) is high, so it should generally be kept in this state for shot blasting. If limited by the shape of the part, it is necessary to use small Angle shot blasting, the size and speed of shot blasting should be appropriately increased.

Fifth, the amount of broken shot blasting: the kinetic energy of the shot blasting fragments is low, the more the shot blasting is broken, the intensity of shot blasting is reduced, and the irregular broken shot will scratch the surface of the parts, so the broken shot should be often removed to ensure that the integrity of the shot blasting (blasting) is greater than 85%. The shot blasting equipment is basically the same, only some auxiliary devices are used to control the shot blasting process more strictly.

In fact, the factors that affect the cleaning efficiency of the shot blasting machine are not only so many, but also include many factors such as accessory materials, working load, temperature, humidity, environment, lubrication, surface processing quality, and motion properties. As long as the equipment inspection is usually done, the wear parts are replaced in time, and the front-line operators learn the relevant maintenance knowledge of the shot blasting machine to avoid unnecessary failures of the machine, so as to improve the production efficiency of the workshop and reduce the generation cost of the enterprise.
