Description

Pulleys are important components for belt conveyors.In order to meet the requirements of long-distance high-speed large-capacity belt conveyor, LIBO adopts advanced finite element method, good-quality material, optimized technical process and  large high-precision machines to produce good-quality and long-life pulleys.
 Technical feature
1、Middle and heavy pulleys will be inspected with static analysis and Three-dimension finite element analysis software, which strictly ensure the quality;
2、the material for shell is *6Mn of more superior performance instead of Q**5, which ensures shell quality and performance, whose content of S and P ensures welding quality;
3、the material for shaft is forged shaft of *0Cr instead of #*5 round steel，which improves mechanical property;
4、the bearing block and taper-lock are ground, which ensure the installation precision;
5、the welding line and shaft are inspected by NDT and the shaft will be tested three times, which can ensure the quality of shaft and welding line;
6、stress annealing will be done after welding with CO2 gas shielded arc-welding machine, which can ensure the quality of welding line;
7、the contact-sealing is adopted, which enjoys more superior dustproof and waterproof;
8、We design and manufacture pulleys according to DIN,JIS,CEMA and ISO standards.
