Belt conveyor protection

Belt conveyor is a common conveying equipment with wide applications. During the use of the conveyor, it is necessary to regularly inspect the functions of each component of the conveyor. Today, Zhanwei Machinery will talk about the testing method and testing cycle of the conveyor protection device.

There are two testing methods for anti slip protection devices: one is the inductive anti slip protection device, which should be able to automatically stop the belt conveyor by rotating the sensor direction; Another method is to lift the roller off the surface of the belt, and the belt conveyor should be able to automatically stop. Test cycle of anti-skid protection device: It should be tested once a day during the maintenance period, and the test record should be filled out.

2. Deviation Protection Test Method: When the belt conveyor is running normally, the rolling guide rod of the deviation sensor is manually pushed, and after a delay of 5-10 seconds, the limit switch is activated to automatically stop the machine, which is considered normal. Deviation protection test cycle: The test should be conducted once a day during the maintenance period, and the test record should be filled out.

3. Temperature protection device: The temperature protection sensor should be checked by the user unit once a day and replaced every 3 months. When replacing, the using unit should obtain qualified sensors from the Mechanical and Electrical Department in advance, and the old sensors that have been replaced underground should be promptly handed over to the Mechanical and Electrical Department for testing.

4. Test method for tension reduction protection device: When the conveyor is stopped, for the hydraulic sensor type tension reduction protection device, the overflow valve of the hydraulic station of the tension device is slowly loosened manually. When the pressure is lower than the specified value, the low pressure fault indicator light on the fault display panel lights up as normal. Test cycle of tension reduction protection device: It should be tested once a day during maintenance and a test record should be filled out.
