DEVICE hydroprotection SUBMERSIBLE MOTOR oil-filled submersible pump

摘要

The invention relates to a petroleum engineering, namely to the seal section protectors used in the oil-filled submersible motors downhole centrifugal pumps. hydroprotection apparatus comprises a compensator. Internal cavity protector seal section and the motor are hydraulically interconnected. Tread hydroprotection configured undivided and comprises cable tokkovvod at the bottom of the tread. The tread composition also includes a coupling for a tread and motor shafts, oil-filled channel disposed in its upper part an overflow valve at least one radial and axial support. Mechanical seal bellows is placed on the shaft in the cavity disposed between upper and lower bearing supports the shaft. The technical result when using this protector - simplification submersible motor assembly in the well and improving its reliability.
