Mining conveyor equipment explosion-proof deviation switch EXKPT1-20-35-X Mining conveyor equipment explosion-proof deviation switch EXKPT1-20-35-X Purpose: Two level deviation protection function, one level deviation alarm signal can be connected to the automatic adjustment device, used to correct the deviation and distortion of the tape. The second level deviation is used as a shutdown signal, which can be connected to the control circuit to achieve shutdown. Belt Switch, also known as Anti Bias Switch. It is a product used to detect the deviation of the conveyor belt of a belt conveyor. It is a safety protection device that automatically alarms and stops the conveyor belt in the event of deviation. The deviation switch has two levels of angles, commonly used are: the first level angle is 10, 12, 20. The second level angle is 30, 35, 45. Basic principle: 1. The deviation switch is set on both sides of the conveyor belt, and the vertical roller should be perpendicular to the edge plane of the conveyor belt, and the two sides of the conveyor belt should be located at 1/3 of the height of the vertical roller. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be installed every 30-35 meters in the middle position of the conveyor.) 4. The deviation switch should be connected to the middle frame of the conveyor through an installation bracket. The switch bracket should be welded to the conveyor frame after the conveyor is installed. The deviation switch and the deviation switch bracket should be fixed with bolts. Construction features: This machine adopts a cast aluminum alloy shell, which has high strength and light weight. The surface of the shell is coated with electrostatic spray coating technology, which is uniform, has strong adhesion, and is resistant to aging. The rotating cam adopts a two-point locking structure, and the vertical roller is fastened with positioning pins to ensure reliable operation. The overall sealing performance of the machine is good, and it can work normally in a submerged state
