Features of KPT1-12/30 deviation switch: · Simple and practical structure, stable and reliable performance, dust-proof, shockproof, moisture-proof, small size, light weight, long service life, easy installation, maintenance free. · Output signal can be interlocked with on-site equipment and can also be delivered to microcomputer control system. · Wide adaptability of power supply: 24-380V two-stage deviation switch is suitable for belt conveyors, which can send out alarm signals and further automatic parking before the belt deviation will cause serious hanging edge wear or even tearing accidents. Can timely and effectively protect equipment A's 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 working principle is that the two-stage 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. Usage of the deviation switch: The deviation switch KPT1-12/30 is used to activate the local switch and immediately shut down the tape conveyor in case of an emergency on site, to prevent the accident from escalating. Due to its convenient installation and reliable switch operation, this machine has been widely used in the field of tape conveyors. Widely used in various fields such as metallurgy, coal, cement and building materials, mining, power, ports, metallurgy, chemical industry, etc., including conventional belt conveyors, underground cable support belt conveyors, ship loading and unloading systems, stacker/reclaimer conveyors, inclined and shuttle conveyors, cranes, excavators, boom limiters, skirt feeders, etc. 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. Deviation switch function: When the running tape deviates, the edge of the tape drives the vertical stick to rotate and squeeze to tilt. If the tilt angle of the vertical stick is greater than the first level action angle, a set of switch signals will be generated by the switch. If the vertical stick continues to tilt more than the second level action angle, another set of switch signals will be output. Two sets of switch signals can be used for warning or shutdown, the tape machine can reset and operate normally, and the upright rod can automatically reset< br/>
