RECEIVING-AND-DISCHARGING DEVICE OF AIRTIGHT CENTRIFUGAL SEPARATOR Russian patent published in 2002 - IPC

FIELD: equipment for separating mixture of two fluids in field of centrifugal forces. SUBSTANCE: receiving-and-discharging device includes centrifugal pumps for discharge of separated fractions. Centrifugal pumps have chambers installed on separator cover and accommodating impellers attached to shaft. Located on said shaft are bushing forming concentric channels for supply of heavy and light fractions to centrifugal pumps. Inlet channel of initial fluid is located inside device shaft which is rigidly connected with shaft of separator drum. Device has contactless seals of centrifugal pump chambers including circular chambers accommodating impellers mounted on shaft. Said impellers during their rotation form a circular layer of heavy fraction in said chambers. EFFECT: increased service life, and reduced expenditures for servicing of separator. 1 dwg
