DEVICE FOR PROTECTION OF GAS SEPARATOR BEARING Russian patent published in 2020 - IPC F04D13/10 E21B43/00 F04D15/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry and can be used in gas separators, which are part of submersible electric centrifugal pumps. Proposed device comprises divider head with channels for discharge of separated liquid and discharge of separated gas into annular space of the well. There is a shaft with a bearing, which is provided with possibility of rotation. Note here that baffle-baffle is installed in channel for discharge of separated gas into annular space of the well before bearing. It has at least three seals between rotating and stationary parts in form of labyrinth. Seals are formed by annular channels of small cross-section. They prevent passage of gas. In the separating head there is a hole for supply of lubricating liquid from the channel with the separated liquid.

EFFECT: increased reliability of gas separator bearing operation due to elimination of dry friction in bearing.
