Three core factors of idler in conveyer belt
Clicks:2825 Date:7-5
Most of the conveyor belt, the conveyor roller use environment exists in water pollution and dust, the material of roller tube wear or corrosion, therefore, conveyor belt manufacturers to introduce to you the use of Technology: the ideal roller roller must also have three core technologies: Labyrinth 1, never pollution sealing technology; 2, roller manufacturing high precision and good consistency; 3, supporting technology and corrosion resistant pipe.
Pouring water and dust into labyrinth seals is a physical principle that has not been discovered. As we all know, labyrinth seal gap is large, the sealing effect is not good, is correct. However, the labyrinth seal gap is small, the number of layers, the sealing effect will be good understanding, but it is a big misunderstanding. The second core technology is the manufacturing accuracy of the idler.
China before 1995, the roller is made of cast iron bearing seat, the two ends of the tube body processing step hole, interference pressing production; after 1995, gradually improved by pressing the bearing seat, both ends of the tube body processing small step hole, carbon dioxide gas shielded welding production. The two processes are not guaranteed concentricity of less than or equal to 0.05mm each roller bearings on both ends of the position, not only the rotation resistance of roller bearing life is greatly reduced. The third core technology is the anti corrosion and abrasion resistance of the roller tube.
In the steel industry, coke, sinter, pellet, wear of steel slag is very serious, the roller 4.5mm thick steel tube body, wear off cycle is the shortest only ten days, an average of 6 months; in the coal mine, according to the different sulfur water roller, steel tube body corrosion, every month the most serious corrosion of nearly 1mm, generally about 0.3mm. Often in the coal mine to see bearings and other conveyor belts, roller parts are good, worn and corroded roller tube body "a mess, miserable."".
