FOLLOWING W.P.S. ON THE TEMPERATURE CONTROL BETWEEN WELDING, JIMWAY EXTEND THE SERVICE LIFE OF PULLEYS WITH WELD BEAD'S STRESS ELIMINATION AND THE QUALITY CONTROL OF THE WELD BEAD BY NDT.
Belt conveyor combine with motors, pulleys, belt and rollers. The function of the drive pulley is to transfer the drive force from the pulley surface to the belt; in consequence, the quality of pulleys is the major part of the conveyor running smoothly. Jimway focus on the structural design and production process, also develop our own stress analysis of the program counter to maintain the production process. A smooth angle “R”, made by processing in the shell to end disc welds, influences stress-bearing and the service life. Jimway corresponds ISO standard and can be customized.
