Belt conveyor roller and conveyor belt in the conflict will occur when the temperature, the temperature on the belt conveyor of all the operation and security has a very important meaning. The temperature measuring instrument, detection device and to emit ultra-high temperature signal, the receiving signal is delayed by 3 seconds to perform the move received a bit, cut off the motor power supply, active transport machine stop switch, to maintain the effect of overheating. Belt conveyor for mining coal mine. If a conveyor is not operated in operation, blocked by the media, or other reasons for this suspension. Coal position sensor to touch the corresponding temperature, coal immediately adopted the move to maintain the circuit, so that the conveyor belt immediately suspended. The back end of the coal transported in the end, the conveyor to make the appropriate termination, until the loader active suspension of operation. Each type of conveyor should be in the correct local, the device sensor, due to a simple damaged conveyor belt.
Roller and conveyor belt friction, the temperature measuring instrument, close to the detection roller mounting device (transmitter) issued over temperature signal, the received signal is delayed by 3 seconds from the execution of the action part, turn off the power automatic conveyor stop switch.
Introduction of temperature protection method for belt conveyor
Roller and conveyor belt friction, the temperature measuring instrument, close to the detection roller mounting device (transmitter) issued over temperature signal, the received signal is delayed by 3 seconds from the execution of the action part, turn off the power switch, automatic stop conveyor, plays the role of overheating protection.
Mining of belt conveyor with head and coal position. If a conveyor operation or accidents cannot be blocked or the coal bunker is full, parking lot or other reasons, piles of coal, coal and coal DL corresponding to the position sensor contact, a protection circuit, take immediate action to immediately stop the conveyor belt. And then continue to face the coal, the back end of the coal transported in the rotation by the station after the occurrence of a proper stop, until the loader automatically stops running.
Each type of conveyor should be in the right place, the multi conveyor belt will be easy to break through. At this time, we should pay attention to maintenance.
Mine belt conveyor belt, if failed, such as motor burned, the damage of the mechanical transmission part, a belt or a chain belt slipping fracture, etc., on the conveyor belt is installed on the magnetic induction switch accident of passive components cannot be closed or the secretary is not closed, then the normal speed control.
