FIELD: mechanical engineering.
SUBSTANCE: submersible pumping unit comprises screw pump mounted in the receiving pipe and connected with the submersible electric motor through a spline coupling. The bottom section of the receiving pipe is connected with the housing of the submersible electric motor, and its top section is connected to the pump-compressor pipe. The inner side of the receiving pipe is provided with the spring centering guide that holds the screw pump at its axis. The top section of the screw pump receives a connecting-disconnecting mechanism that locks it in the receiving pipe. The bottom section of the housing of the screw pump receives slot guiding bushing for locking the screw pump in the connecting spline bushing arranged in the bottom section of the receiving pipe. The housing of the screw pump is provided with a sealing ring that seals the high-pressure space of the receiving pipe hermetically.
EFFECT: expanded functional capabilities.
