DB-PP belt conveyor deviation switch DB-PP (sturdy structure) 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. The deviation switch DB-PP (sturdy structure) is used to control the deviation phenomenon during the operation of the belt conveyor. It outputs an alarm or shutdown signal based on the actual deviation amount of the belt, which can effectively prevent accidents caused by belt deviation. This series of deviation switches has a two-stage action function. The first level action is used for alarm, and the second level action is used for automatic shutdown. When the tape machine is running, when the tape deviates and comes into contact with the vertical roller of this switch, the vertical roller rotates. If the deviation continues to increase, the squeezing vertical roller will shift. When the deflection angle of the vertical roller exceeds 12 °, the first level switch acts and outputs an alarm signal. When the deflection angle of the vertical roller exceeds 30 °, the secondary switch acts and outputs (shutdown signal). Parameters: Voltage: 220V/380V/480V, current options: 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A.15A. The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation. After troubleshooting, when the tape leaves the vertical roller for normal operation, the vertical roller can automatically reset. In order to adapt to long-term use under outdoor conditions, this product is sealed as a whole, and the internal metal parts are galvanized and purified. The external parts, except for the shell, are coated with multiple layers of bright chrome. The shell is made of cast aluminum/stainless steel, and the surface is treated with electrostatic spraying technology, making it suitable for use in harsh environments< br/>
