SUBMERGED MULTI-STAGE ELECTRIC PUMP Russian patent published in 1995 - IPC

FIELD: pump engineering. SUBSTANCE: electric motor, pump sections and catching head have conical flanges and interconnected through yokes. The yokes consist of two cylinder parts which enclose the conical surfaces of the flanges tensioned by bolts and defining a cylinder with internal cylindric bore when assembled. The sides of the bor are conical. The plane of connection of the cylinder parts is arranged over the axis of the electric pump. The longitudinal axis of the bore is coincident with the pump axis. Cable is fixed with respect to the yokes. The yokes are made up as unequal parts of the cylinder. The groove is made in the grater part of the cylinder. The cable is mounted within the groove for fixing. EFFECT: enhanced efficiency. 3 dwg
