The Blast Wheel Wear And Cause Of Failure To Explore And Sub-pill Round Structure On The Rate Of Shot Blasting

In this article, the author reviews the evolution of the modern blast wheel. It is indicated that the developing in shot-feeding modes are the main direction in blast wheel, and the applying situation and developmental tendency of the machine are presented briefly. In this paper, the motion of shots entered the windows on shot blasting impellers has been analyzed. The velocity of shots in the pile formed in the windows on shot blasting impellers has been deduced when the blast wheel is working normally. And also, the critical localization of shots flying off the window in the control cage has been analyzed. The movement of shots in the clearance of the control cage and the impeller has also been analyzed. According to their motion model, their angular velocity has been educed while they disengage from the clearance. And also the quality of shots in the impeller and the clearance has been deduced. The new modality of the pile formed in the windows of the shot blast wheel has also been described. The velocity of shots flying off the window of the control cage are calculated, and also the position of shots coming into collision with the vane are confirmed. The movement of shots after the collision are analyzed, it is indicated that the shots come into collision with the vane for several times before they fly off the blast wheel. Contrastive experiments were done. It shows that the parallel windows impeller the parallel windows with flutes impeller are new kinds of impellers with larger shot blast capacity ,higher efficiency. And also the shot blasting capacity and efficiency are affected by the length of the screw. Furthermore, the invalidations of the impeller, the control cage and especially the vane are analyzed from the angle of the energy. This provided a new way to prolong the life of the impeller and the control cage.
