Analysis And Rectification of The Oil Leakage Problem of The Supercharger Inlet Pipe of A Certain Model
Supercharger inlet pipe assembly polytetrafluoroethylene(hereinafter referred to as PTFE)hose leakage occurred during the use of scanning electron microscopy found that the fracture fiber adhesion is not completely discon-nected,from the inside of the hose to observe the wound near the fracture is not completely split,and the leakage of the hose fracture and knife cut,burn fracture,blasting fracture and other hose fractures are compared,observed and ana-lyzed.And the PTFE hose molding sintering,hose cutting,braid reinforcement,component clamping,assembly,test verification of the whole process of the investigation,the results show that PTFE hose is twisted stress in the installation process,vibration and internal oil pressure in the process of engine operation,along the initial stress direction from the inside to the outside of the transverse tear,resulting in oil leakage failure.
