Large Refinery Unit Bearing Repair And New Technology Instance

Though slipping bearing researched deeply in theory, the effect that combines theory with practice is not very perfect. Engineering technicians in the factories have practical experience relatively rich, but on the other hand, lack If theory knowledge.Aimed for fluid dynamics lubricated theory, application practice of different slipping bearings combined in large scale centrifugal set of oil refineries, overhaul and repair method are described in all round way, which includes five slipping bearings commonly, cylinder bushing, elliptic bushing, four wedge shaped tillable bushing and Michelle thrust bushing. A new technology is proposed, that is, how to process, scrape and grind fixed 4 wedge shaped bushing of catalysis flue gas turbine that has a role in oil refineries. By means of designing and calculating, processing standard model shaft, catalysis flue gas turbine bushing is scraped, grinded and repaired which forms a set of new processing technology method to provide a reliable assurance for catalysis flue gas turbine in oil refineries that makes high quality overhaul and high level operation. For cylinder and elliptic bushing, processing, scraping and grinding methods are researched emphatically. It is an overall scientific method scraping and grinding two bushings that combines mechanical processing with scraping and grinding model shaft. For and, repair method during the operation procession is researched emphatically. It is very simple and practical.Through many times research, a conclusion is drawn in this article on the basis of practice and it has high practical value. It has a certain guide for engineering technicians and technical workers in industrial enterprises, which is useful to master skillfully processing, scraping and grinding method of different slipping bushing and raise the overhauling quality of large scale set.
