FIELD: motors and pumps.SUBSTANCE: invention relates to the hydrocarbon production and is intended for pumping of fluid by submersible electric centrifugal and electric screw pumps of various types with the submersible electric motor in a sealed housing or in other arrangement. According to the invention the sealed housing is connected with the input unit using the split nut located in a recess of the input unit, and the housing during assembly and disassembly is moved along the key, or the sealed housing and the input unit are joined through the intermediate connecting element with guiding keys or with right and left thread, that excludes mutual rotating of the sealed housing and input unit, twisting of the power cable in the housing and its damage.EFFECT: method ensures sealed joint of the housing of the submersible electric motor with the input unit of submersible pumps, which is designed without axle shift with reference to the housing elements, with flanges for joining with the pump and submersible electric motor.8 dwg |
