CENTRIFUGE DRIVE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: mounted between outer surface of float and inner surface of cylindrical shell are sealing members secured to the shell and arranged in its upper and lower parts. Sealing members are made in form of flexible tires. They form hermetic chamber together with walls of float and cylindrical shell. Flexible tube mounted in cylindrical shell above lower sealing member is used for draining liquid from the hermetic chamber. Power requirements of drive are considerably reduced due to reduction of friction losses during rotation of float. EFFECT: reduction of power requirements of drive through reduction of area of direct contact of revolving bearing float with liquid. 1 dwg
