Belt conveyor belt deviation is one of the common faults in the operation of belt conveyor, and there are many reasons for it, including equipment manufacturing, installation and commissioning, operation and maintenance, etc. In order to facilitate memory and quickly judge the cause of belt deviation, the following formulas can be summarized:
1.The reason for the deviation is no outer end, and the center line of the hammer is tensioned.
2.The material drop point is not accurate, and the drop is too large and not straight.
3.The roller rotates inflexibly, and the bearing is damaged and does not rotate.
4.The belt joint is not perfectly round, and the belt itself is not straight.
5.The drum installation is not level, and there is a problem with the front and back tilt.
6.The axes of the drive and driven rollers are not parallel, and the axis line is tilted to the center line of the frame, causing the belt to deviate.
7.The axis of the drive and driven rollers is not perpendicular to the center line of the frame, causing the belt to mistrack.
8.The distribution of materials on the belt is uneven, and one side is more and the other side is less, resulting in belt deviation.
9.The belt is subjected to additional lateral forces during operation, such as sudden stops or impact forces during start-up, which cause the belt to deviate.
10.The belt is subjected to longitudinal forces during operation, such as bending or twisting, which causes the belt to deviate.
In view of the various reasons mentioned in the above formula, corresponding measures can be taken to solve them, such as adjusting the position of the tensioning hammer, readjusting the material landing point, replacing the damaged rollers and bearings, correcting the belt joints, adjusting the installation level of the drum, correcting the parallelism and perpendicularity between the axis line of the drive and driven rollers and the center line of the frame, adjusting the distribution of materials on the belt, avoiding impact force during sudden stop or start, and avoiding the belt from longitudinal force, etc.
In short, mastering the above formulas can help us quickly judge and solve the problem of belt conveyor belt deviation, and improve the efficiency and safety of equipment operation.
