Rubber loop sealing ring automatic tester - takes up sample by conical mandrel, rolls to extend and reduces between cylindrical surfaces

摘要

The O-ring (7) is placed on a conical mandrel (8) that extends it. It is further extended in by conical sleeve (2) cooperating with the mandrel. Under radial tension, the sealing ring is overturned and moved in a circular cylindrical space formed between an inner cylindrical surface (13) of the sleeve and an outer cylindrical surface (26) of the mandrel. The surface of the ring under test is optically examined for faults. Pref. the cylindrical end-piece (15) of the sleeve is of transparent material. USE/ADVANTAGE - Quality control of sealing rings for hydraulic or pneumatic installions in machines or vehicles. Controls and inspects complete surface of O-ring in extended state, ensuring secure sealing and cheaper mfr.
