Title (EN) METHOD OF EXTENDING THE SERVICE LIFE OF USED TURBOCHARGER COMPRESSOR WHEELS
(FR) PROCÉDÉ DE PROLONGEMENT DE LA DURÉE DE VIE DE ROUES DE COMPRESSEUR DE TURBO
Abstract:
(EN) A method is provided for renewing a used metallic compressor wheel (14) having a damaged surface. The method generally comprises the steps of inspecting the used compressor wheel (14) for fatigue cracks and, if fatigue cracks exceeding a predetermined length are not present, renewing the used compressor wheel (14) by peening. The inspection process comprises conducting a non-destructive examination of the used compressor wheel (14) to detect cracks larger than those which would fall generally within the compressive stress zone that is generated with peening.
(FR) La présente invention concerne un procédé permettant de renouveler une roue de compresseur métallique utilisée (14) présentant une surface endommagée. Le procédé comprend, généralement, les étapes consistant à inspecter la roue de compresseur utilisée (14) afin de déceler des fissures de fatigue et, en l'absence de fissures de fatigue dépassant une longueur prédéterminée, renouveler la roue de compresseur utilisée (14) par martelage. Le procédé d'inspection consiste à réaliser un examen non destructif de la roue de compresseur utilisée (14) pour détecter des fissures plus grandes que celles qui serait obtenues généralement dans zone de contrainte de compression qui est générée avec le martelage.
