LIQUID CONCENTRATOR WITH SEALING DEVICE Russian patent published in 1997 - IPC

FIELD: sealing devices of liquid concentrators. SUBSTANCE: rotor has first sealing end located perpendicularly to axis of rotation of rotor forming clearance with second sealing end. First and second ends define area where pressure differential and seal are formed. First sealing end has at least one trajectory for flow of liquid to keep it under action of balanced centrifugal force and force of pressure differential for forming the seal in clearance between first and second sealing ends. EFFECT: enhanced reliability. 8 cl, 13 dwg
