Two stage belt deviation switch HFICDT1-12-30& The XLPP-J-IIHFKPT1-12-30 two pole deviation switch is made of high-precision aluminum alloy produced by die-casting, with high strength, light weight and sturdy outer shell. The outside is painted in red and yellow, smooth and bright. Easy to discover. Used for emergency shutdown of belt conveyors due to belt deviation. Explosion proof two pole deviation switch is a product in conveyor belt automation. Can be used for underground and cableway support belt conveyors; Ship loading and unloading system; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Cranes, excavators, boom limits; Skirt feeder/conveyor; The heavy-duty limit switch detects the deviation of the adhesive tape, which is a protective device for automatic alarm and shutdown of the adhesive tape machine control. Usage: Used to detect the deviation phenomenon of belt conveyors during operation, output alarms or shutdown signals based on the actual deviation amount of the belt, and effectively prevent accidents caused by belt deviation. It is a protective device that realizes automatic alarm and shutdown of the tape machine control. Basic principle: When the conveyor belt deviates during operation, the conveyor belt touches the switch roller and causes the roller to deflect. When the roller deflection angle reaches level 1 switch angle, the switch sends an alarm signal. When the conveyor belt deviates seriously and reaches the second level switch angle, the switch sends a stop signal to automatically stop the conveyor belt due to deviation fault. When the deviation fault is eliminated and the tape machine is running normally, the switch vertical roller can automatically reset and return to the initial state. Installation and adjustment: 1. The deviation switch should be set on both sides of the conveyor belt, and the vertical rollers should be perpendicular to the edge plane of the conveyor belt, with both sides of the conveyor belt located at 1/3 of the height of the vertical rollers. 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< br/>
