Belt tearing detection devi TYZL - B - II, tear switch is longitudinal tear of detecting element, when in the operation of the adhesive tape tearing, sensors can be reliably detected, and a switch output, control box reived signal from the sensors, control relay action, output a switch to the control room and automatic emergency stop, panel alarm indicator flash at the same time, the control circuit self-locking, to restore normalcy to control circuit, can press reset knob on the panel. In addition, there is a self-calibration button on the panel. When this button is pressed, it can simulate the tear failure and check the work of the control system.
Purpose and scope of application: belt conveyor in the pross of conveying material, due to the material, debris or easy scratches or through the conveyor belt of the metal, especially the steel wire rope conveyor belt will cause the longitudinal tear accident, bring significant loss state property. The longitudinal tear monitoring devi of ZL series is capsule type, which can reliably send out alarm signal and stop signal when the conveyor belt is tearing, so as to avoid the expansion of accident. It is suitable for the safety protection of belt conveyor belt in all industries.
Working principle and performan.
The ZL series longitudinal tear monitoring devi consists of a perptron and a control circuit. Perptron is longitudinal tear detecting element, when the conveyor belt conveyor is different material after penetration, with the conveyor belt running to drive foreign bodies make the perptron is extruded, or when the chute discharging mouth and conveyor belt in a material jam for extrusion between the arrangement of the sensors in the discharging mouth, the sensors are sensitive and reliable to detect the conveyor belt tearing and switch output signal, signal downtime. The control circuit has the function of self-locking and delay. The control box panel has alarm indicator light. When the conveyor belt is tearing, the control circuit reives the switch signal detected by the sensor, and sends alarm and stop signal. This perptron trough structure, is applicable to trough belt conveyor, below the bearing installed on the conveyor belt, the main monitoring caused by a material through lose to send with tear accident, signal accident, so as to prevent or redu conveyor belt tearing
