The working principle of the BHFKPT1-20-35 two-stage deviation switch for conveying equipment accessories is that the BHFKPT1-20-35 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. Features: Simple and practical structure, stable and reliable performance, dust-proof, shockproof, moisture-proof, small size, light weight, long service life, easy installation, maintenance free. The output signal can be interlocked with on-site equipment and can also be delivered to microcomputer control systems. Power supply adaptability: 24-380VBHFKPT1-20-35 two-stage deviation switch. Precautions: 1. The deviation switch gear wheel should be kept perpendicular to the belt. 2. It is recommended to maintain a distance of 120-160mm between the gear wheel of the deviation switch and the edge of the belt. 3.
