The function of the spraying roller is to support the conveyor belt and the weight of the material. The spraying roller operation is flexible and reliable. Reducing the friction between the conveyor belt and the supporting rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the idler is a small part in the belt conveyor and the structure is not complicated, it is not easy to manufacture the idler.
The criteria for judging the quality of the idler are as follows: the radial runout of the idler; the flexibility of the idler; and the axial shift.
Operation of spraying roller:
1. Before using the rollers, you should carefully check the appearance for serious bumps and damages. The rotating rollers should rotate flexibly without jamming.
2. The installation distance of the idler should be determined by scientific calculation according to the type of logistics and the characteristics of the conveyor. Avoid over-sparse or dense installation.
3. The roller installation should be adapted to avoid friction between each other.
Maintenance of spraying rollers:
1. The normal service life of the roller is more than 20000h, and generally no maintenance is required. However, according to the place of use and the size of the load, a corresponding maintenance date should be established, timely cleaning and oil injection maintenance, and timely cleaning of floating coal. Replace the rollers with abnormal noise and non-rotation in time.
2. When replacing the bearing, make the bearing cage opening outward. After the bearing is installed in the idler roller, the proper clearance should be maintained and it should not be crushed.
3. The labyrinth seals shall use original accessories. They shall be packed into the rollers separately during assembly, and shall not be put together for assembly.
4. When using the middle roller, prevent heavy objects from hitting the roller tube body.
5. In order to ensure the sealing performance and performance of the roller, it is prohibited to disassemble the roller at will.
