The use of grooved roller conveyor belt:
1, to prevent the conveyor belt load start.
2, conveyor belt deviation, should take timely measures to correct.
3, different types, specifications of the conveyor belt should not be used together, the joint is best to use glue method.
4, buffer roller type, structure, specification, number of layers should be based on the use of reasonable selection.
5, the conveyor belt running speed should not be larger than 2.5m/s, the block is large, the wear of the material and the use of fixed pear discharge device should be as low as possible.
6, the roller conveyor drum diameter and conveyor belt layer, the transmission drum, hoist to the roller and the supporting roller angle requirements should be based on the design of the transport, reasonable selection.
7, the feeding direction along the direction of belt, in order to reduce the material falling on the conveyor belt impact should adopt the chute, reduce materials gap distance; the conveyor belt feeding section, should shorten the distance between rollers and the buffer roller for material leakage, conform to the conveyor belt adopts the material blocking plate is soft and moderate, in order to avoid gear plate is excellent, scraping conveyor belt surface.
8, the friction roller in use, such as the lack of a roller, should be promptly added and repaired; roller materials were covered by rotary, prevent leakage between the card on the tapered roller and belt conveying belt, pay attention to lubrication of the movable part, but not the oil conveying belt.
9, avoid suffering from the conveyor belt rack, block pillar or bulk material, prevent Pengpo tear, bucket elevator conveyor belt that local damage, application of artificial cotton and timely repair, so as not to expand.
The mean diameter of the roller is the change of the outside diameter of the roller because of the deformation of the roller. The radial jump is caused by many reasons, which can not be predicted and avoided, but can only be controlled in a small range, so as to ensure the reliability and service life of the roller. The relevant standards of the state on the roller roller radial jump values according to different diameter of roller made the relevant provisions, and some roller manufacturers to establish their own set more stringent standards to ensure the quality of products.
Through the analysis of the production and assembly process of the roller, it can be seen that there are two main reasons for the roller diameter jump:
(1) deformation of the roller tube during sawing or assembly;
(2) in the process of assembly, the deviation between the center of the roller tube and the center of the idler. Whatever the reason, it is a gradual process, not a sharp mutation. |
