Paper machine dryer shaft wear background:
At the end of the year, a paper enterprise found that there were two places of wear on the side shaft head of the 2 dryer support, and the axial movement of the bearing seat was serious, and the wear and tear situation was: bearing model 1: 12 cone spherical roller bearing 23136CAK W33, spindle shaft diameter 180mm, unilateral wear 12 18mm, wear width 96mm The damage to the inner ring of the bearing has a serious impact on the normal continuous production of the enterprise. After conducting technical exchanges and analyzing the causes of the failure, the relevant leaders understood that our company's technology can be used to ensure the quality and effect of the use, without disassembling the equipment as a whole and completing the repair work within eight hours at the earliest, and decided to carry out on-site rapid repair through Soray carbon nanopolymer material application technology during shutdown and maintenance.
Soray engineers repair the dryer shaft of a paper machine
Soray's repair technology is to use the unique mechanical properties of carbon nanopolymer materials and targeted repair processes to repair the wear of various shafts. In view of the wear of the paper machine dryer shaft, according to the equipment operation parameters, drawings and dimensions of parts and components provided by the enterprise, after careful analysis by the technical personnel of our Soray Industrial Solution Center, combined with our previous successful experience in repairing large-scale pipe bundle equipment, chemical treatment tanks, screw presses, crushers and other equipment, the process steps of the on-site repair are determined, and the on-site repair scheme we provide can meet the operation requirements of the repaired equipment.
After communicating with the enterprise in the early stage, our company's technical engineers combined with the analysis of equipment operating parameters and wear degree, the use of Soray "taper shaft repair process" can meet the repair requirements of the shaft, that is, the use of the unworn size on the shaft as a benchmark to determine the coaxiality, combined with the auxiliary positioning of the special model ruler of Solei, after determining the coaxiality of the bearing and the shaft, and the use of Soray carbon nanopolymer material technology repair process to restore the shaft diameter to achieve rapid repair, to meet the normal operation of the equipment.
