Conveyors require multiple components to work together to operate stably and normally. The roller is an important part of the belt conveyor, accounting for 35% of the total cost and more than 70% of the resistance, so the importance of the roller is indescribable. In the process of using the roller, users should pay attention to the five matters of maintenance and repair.
Idlers are used to support the quality of the conveyor belt and the material, and their operation must be flexible and reliable. Reducing the friction between the belt and the idler plays a key role in the life of the belt, which accounts for more than 25% of the total conveyor cost. So how to maintain and repair the idler?
Maintenance and repair methods/procedures
1.The normal service life of the roller is more than 20,000h, and it generally does not need to be maintained. However, according to the size of the place of use and the load, the corresponding maintenance date should be formulated, and the oil injection maintenance should be cleaned in time, and the floating coal should be cleaned up in time, such as the use of sticky dust rollers. The rollers with abnormal sound and non-rotation should be replaced in time.
2. When replacing the bearing, the bearing cage opening must be outward, and after the bearing is loaded into the idler, the appropriate clearance should be maintained and not crushed.
3.Labyrinth seals should be made of original accessories, and should be assembled separately into the rollers, and should not be assembled together.
4.When using the roller, it should be strictly prevented from hitting the roller body with heavy objects.5.In order to ensure the sealing performance and use performance of the roller, it is forbidden to disassemble the roller at will.
