Analysis of Causes of Interruption of Screw Conveyor Operation

2015-04-14 10:04:12 　　 The screw shaft is broken when the user is using the screw loading conveyor . The main shaft of the screw conveyor is broken due to the following reasons: the middle hanging bearing is blocked, the screw blade is jammed by the material dead. 1. The long-distance screw conveyor is connected by a section of the body, and the screw shaft is connected through a hanging bearing. The connection between the previous section of the spiral and the back section of the spiral is used to connect the connecting shaft on the bearing through the middle hanging shoe Bolted together. The screw connection bolt is subjected to two forces: 　　 one is the pre-tightening force after being tightened by itself. The second is the torsion moment of the spiral rotation and the shear force acting on the bolt. If the material particles are too large, the blades will collide with the materials during the rotation, the blades are easily damaged, and the blades are easily blocked, causing the screw shaft to break.　　2. When the material enters the suspension bearing, the inside of the suspension bearing is blocked by the material, and the screw shaft is jammed and cannot rotate. It is also easy to cause the main shaft of the screw loading conveyor to break.　　 Therefore, the maintenance of the screw conveyor is one of the indispensable links in the production work of the enterprise. If you do not pay attention to the maintenance of the equipment during use, the service life of the equipment will be reduced.　　In addition, the machinery reminds you to pay attention: the screw conveyor must be fixed well before use to avoid shaking of the equipment during use.
