Common Faults and Solutions of Shot Blasting Machine (Part Two)

Shot blasting machine is vulnerable to consumption. It will occur a variety of problems during operation, so Jiangsu Longcheng Casting Machinery sum up the common problems and their treatment methods.

Cause analysis and measures of the control cage failure

Fixed on the casing of a shot blasting machine, directional rotation sleeve can be thrown when the steel shots change direction. When a set of internal directional deep groove or directional cover opening is ground to about 10 mm, then it should be replaced. The direction of the deviation of the angle between the nest and the center of the impeller determines the radial scattering angle of the projectile, which is about 45 degrees.

Damage and replacement of distributor

The distributor is fixed on the main shaft to rotate together with the impeller. The distributor is wearing parts, and when the distributor wear more than 15 mm then it should be replaced. If you continue to use, the radial steel shot scattering angle will increase the guard plate wear, then reduce cleaning effect.

Damage and replacement of impeller

The impeller of the shot blasting machine is fixed on the combined plate by 8 bolts. In order to ensure the stability of the operation, the impeller should be regularly checked to see whether there is a shake and the impeller wheel roundness and stress situation. The impeller should be replaced timely when any serious wear is found.
