BCL-305 / A circulating hydrogen compressor Lanzhou Petrochemical refinery from abroad an important station for the hydrogenation plant equipment, which after a long period of high-speed operation , parts in varying degrees of wear, particularly the compressor rotor shaft bushing wear the most, causing significant decline in overall efficiency , Lan Lian Machinery Factory undertake this rotor repair tasks. Structural characteristics of imported equipment , through careful analysis and discussion of hot charging process to solve the high-precision rotor center hole can not be used in the case of large interference fit bushings installed production problems , successful repair of the rotor . While the reference standard , with domestic metal materials instead of imported materials, imported equipment at home for the renovation and repair of the foundation . Currently this equipment in Lanzhou Petrochemical refinery hydrotreating unit running smoothly, normally, repair work to achieve the desired effect.
