Explosion proof KPT2 two-stage deviation switch& FSPK-12-30 structural features: The explosion-proof KPT2 two-stage deviation switch has a universal installation design that allows the deviation detection device to be installed freely at the top or bottom of the conveyor longitudinal beam; Closed, corrosion-resistant, and sturdy cast aluminum casing. Protection standard IP65, capable of long-term operation in harsh environments; The cover plate can be removed for maintenance without the need to remove the action lever; Imported action rod bearing, capable of operating at a speed of 4000 rpm for a long time; When the action angle is 12 °, the alarm contact will act. When the action angle is 30 °, it is the output of the shutdown signal. Explosion proof KPT2 two-stage deviation switch installation: The deviation prevention switch can be fixed at the top or bottom of the conveyor longitudinal beam, and the action rod is about 25mm away from the edge of the belt. Usually installed on both sides of the belt at a distance of 0.3-2 meters from the head or tail. When the belt deviates, it forces the actuating rod to deviate and triggers the alarm switch. If the deviation continues, triggering another set of switches will result in a protective shutdown of the conveyor. The basic principle of explosion-proof KPT2 two-stage deviation switch: When the conveyor belt is running and in contact with the switch vertical roller, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. The superior 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. 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< br/>
