The tensioning process of a 180 degree turning belt conveyor involves multiple aspects, and the following are some key steps and precautions: 
1、 Preparation before tensioning 
Check the status of the conveyor: Ensure that the conveyor is in a stopped state and disconnect the power supply to ensure safe operation. 
Preparation tools: Prepare the necessary tensioning tools, such as tensioning devices, bolts, wrenches, etc. 
2、 Tightening steps 
Adjust the parallelism between the drive shaft and the passive shaft: Ensure that the drive shaft is parallel to the passive shaft to avoid problems such as belt conveyor deviation and tooth skipping on one side. 
Fixed drive end bearing and sprocket: Fix the drive end bearing and sprocket, and adjust the center distance of the sprocket. 
Bilateral parallel tension: At the passive end, perform bilateral parallel tension from loose to tight. Lift the lower belt vertically upwards with your hand until the chain is at a certain distance (such as 50mm) above the lower track to ensure that the belt has the appropriate tension. 
Fixed passive end bearings and tensioning bolts: After adjusting the tension, fix the passive end bearings and tensioning bolts to prevent the belt from loosening during operation. 
3、 Inspection and adjustment after tensioning 
Check the tightness of the belt: Ensure that the belt tightness is moderate, neither too tight nor too loose. It can be judged by observing the running state of the belt on the drum, measuring the gap between the belt and the drum, and other methods. 
Idle test machine: After the installation and tensioning of the conveyor are completed, conduct an idle test machine. Observe whether the belt runs smoothly, whether there is any deviation, and whether the operating temperature of the driving part is normal. 
Adjust the tensioning stroke: Flexibly adjust the tensioning stroke according to the actual situation. For conveyors that are in operation for a long time, due to factors such as belt wear and elongation, it may be necessary to increase the tension stroke appropriately; For newly installed or recently repaired conveyors, it may be necessary to reduce the tension stroke appropriately. 
4、 Precautions 
Safe operation: When adjusting the tensioning stroke, attention must be paid to safe operation to avoid accidents such as personnel injury or equipment damage. Operators should receive professional training and be familiar with equipment operating procedures. 
Regular maintenance: Regularly inspect and check the conveyor to promptly detect and eliminate possible faults. At the same time, strengthen the training of operators and maintenance personnel to enhance their professional skills and safety awareness. 
In summary, the tensioning process of a 180 degree turning belt conveyor requires careful operation and comprehensive inspection to ensure the normal operation and safety of the conveyor.
