FIELD: engines and pumps.
SUBSTANCE: claimed method allows a sealed split joint at downhole motor electric line input module. Pump input module consists of the housing that features no shifts of its axis from casing elements and flanges for connection with pump and drive motor. Module housing is provided with channels for shaft, fluid flows and separate channel for tight two-way coupling of the motor electrical connection, holes filled with electric-insulation fluid and intended for sealing of electric line. Joint tightness is ensured by seal rings and plugs with circular seals or lead and copper washers, or there can be made an open cavity fir sealing the jot by compound. Connection of electric line is executed with the help coupling by mating sealed couplings.
EFFECT: expanded applications, reliable design of right joint, higher safety.
