FIELD: oil producing industry.
SUBSTANCE: invention relates to submersible pumping sets with cooling systems of submersible oil-filled electric motors. Proposed submersible pumping set contains pump, gas separator and drive electric motor arranged in forced flow-around housing with holes on side surface. Centrifugal gas separator is furnished with additional screw unit after separating unit (in direction of liquid flow), inlet part of gas separating channel to remove gas-liquid mixture being formed by space with additional screw unit. Housing is made to provide flow of liquid pumped out of annular space through side holes of housing to inlet holes of gas separator.
EFFECT: improved reliability of pumping set owing to effective operation of force cooling system of drive motor when setting well in operating conditions.
