DEVICE ESTABLISHING CORROSION RATE OF CARBON STEEL 10 Russian patent published in 2004 - IPC

FIELD: measurement technology. SUBSTANCE: domestic washer with vertical-axial rotation of wring-out reservoir carrying balancing ring is employed to establish corrosion rate of carbon steel 10. Proposed device includes vessel and wring-out reservoir-drum mounted for rotation with reference to vertical axis which are components of mobile part of washer. Four supports-bracings with damping members are oriented in space vertically and are hinged to body and internal mobile part. Lower ends of supports- bracings are linked to internal mobile part above its center of gravity so that all points of internal mobile part move translationally with deviation from equilibrium position in vertical plane passing through supports-bracings and center of gravity of internal mobile part. Weight is suspended inside drum at height of 40.0 cm from bottom of drum by wire pulled through two holes made in wall of drum. Ring flute for free movement of tested specimens in the form of balls made of carbon steel 10 and occupying 1/6 part of internal space of balancing ring is installed in addition inside balancing ring. Part of space of ring is filled with 10% aqueous solution of ammonium chloride. EFFECT: improved functional reliability of device. 6 dwg
