Position switch HFKPT1-12-30 deviation switch Position switch HFKPT1-12-30 deviation switch Working principle: The belt position deviation switch is installed on both sides of the belt conveyor, 1-3 meters away from the front and rear ends of the belt conveyor. When the belt deviates, the edge of the belt presses against the gear wheel, forcing it to deflect and causing the limit switch to operate. To reduce friction between the gear wheel and the belt, the main body of the gear wheel is made of bearings< When a minor deviation accident occurs (12 °), the * group contacts of the two-stage deviation switch act and issue an accident warning signal. When a serious deviation accident occurs (30 °), the second set of contacts of the two-stage deviation switch will act, which can automatically stop the conveyor. The position switch HFKPT1-12-30 is a protective device used in conveyor belt automation to control belt deviation. It is used to detect the deviation phenomenon during the operation of the belt conveyor, output an alarm or stop signal according to 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. The position switch is suitable for belt conveyors, which can issue an alarm signal and further automatically stop the belt conveyor before it deviates, causing serious edge wear or even tearing accidents. Can timely and effectively protect equipment safety, avoid accidents from escalating, and achieve the goal of ensuring production and protecting equipment. In addition, since signals can be sent to the control system, it is convenient to achieve factory automation control, which can also achieve the goal of reducing staff and increasing efficiency, centralized control, and facilitating production and scheduling. The structural characteristics of the bidirectional pull rope switch: This machine adopts an aluminum alloy precision die-casting shell, which has high strength and light weight; The shell protection level reaches IP67, with good sealing, waterproof and dustproof, and can work in harsh environments; The contact capacity is large, and the action is sensitive and reliable< br/>
