Non-contact Air Holding Mechanism for Inspection of Pipe Inner Walls
Inspection of pipe inner wall is the most important problem for nuclear power plant. At present there are no non-contact holding technique for the inspection system. For that purpose, we are developing a non-contact inspection system. This paper describes a "first" prototype model of the holder using air pressure, and results of preliminary experiment on air pressure distribution, holding attitude and static holding stiffness. In prototype mechanisms, when the supplied air pressure was 1.2MPa the angle of inclination was within 1', and the holding stiffness was 2N/μm(air film thickness 100μm).
