Belt conveyor KPT1-12-30 two-stage deviation switch Belt conveyor KPT1-12-30 two-stage deviation switch Working principle: The working process of this switch is that when the conveyor belt deviates, the belt touches the switch vertical roller. When the vertical roller deviates to the first level action angle, the first level switch acts and outputs a signal alarm. If the tape continues to deviate and the vertical roller of the switch reaches the level II action angle, the level II switch will send a stop signal. If it is connected to the control circuit, the automatic shutdown and deviation switch can provide protection for the belt conveyor site, so it must meet the IP protection level. The switch is divided into two positions to detect the degree of deviation and twisting of the conveyor belt. Based on the degree of deviation and twisting of the belt, automatic alarm and shutdown are achieved to avoid accidents such as expensive conveyor belt damage and material scattering caused by belt twisting. This switch is easy to install, reliable to operate, and is one of the backup protection devices for belt conveyors. Basic principle: During the operation of the conveyor, when the belt deviates and comes into contact with the switch vertical roller, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. 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. Scope of application: Two level deviation switch for conventional belt conveyors: underground, cable support belt conveyors: ship loading and unloading systems; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Crane, excavator, boom limit: skirt feeder/conveyor: heavy-duty limit switch detects the deviation of the tape, which is a protective device for automatic alarm and shutdown of the tape machine control. Widely used in various belt conveyor equipment in fields such as metallurgy, coal, cement and building materials, mining, electricity, ports, metallurgy, chemical industry, etc. Introduction: The deviation switch is a product used to detect the deviation of the conveyor belt of a belt conveyor. It serves as a safety protection device that automatically alarms and stops the conveyor belt in the event of deviation< br/>
