What are the protection devices for Tianjin belt conveyors?

1. Tianjin Belt Conveyor Temperature Protection: When the belt conveyor drum and belt friction exceeds the temperature limit, the detection device (transmitter) mounted closely to the drum emits an over-temperature signal. Upon receiving the signal, the receiver triggers a 3-second delay, causing the actuator to engage, cutting off the power supply to the motor, and the conveyor automatically stops to provide temperature protection.

2. Tianjin Belt Conveyor Speed Protection: In the event of a conveyor breakdown, such as motor burnout, mechanical transmission damage, belt or chain breakage, belt slip, etc., if the magnetic switch in the accident sensor SG installed on the conveyor's driven parts cannot close or close at the normal speed, the control system will activate the speed protection circuit after a certain delay, based on its inverse time characteristic. This triggers the action of the execution part, cutting off the power supply to the motor to prevent the accident from escalating.

3. Tianjin Belt Conveyor Intermediate Stop Protection: In case a stop is needed at any point along the conveyor, the corresponding switch should be turned to the middle stop position, and the belt conveyor will immediately come to a halt. To restart, first reset the switch, then press the signal switch to send the signal.
