COMPRESSOR UNIT Russian patent published in 2019 - IPC F04B23/00 F04B19/06 F04F1/08 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to the field of compressor machines and can be used in the extraction of oil and gas on land or at sea, including the implementation of the gas-lift method for the removal of water from gas wells. Unit contains a working chamber, made in the form of a gas-liquid separator, a reversible liquid pump and an ejector. Ejector nozzle is hydraulically connected through a non-return valve to the source of the working fluid and the reversing fluid pump. Entrance of the mixing chamber of the ejector is connected through a suction gas valve with a low pressure gas pipeline. Outlet of the mixing chamber of the ejector is connected via an overflow pipe to the upper part of the gas-liquid separator, the output of which is connected via gas through a gas discharge valve to the high-pressure gas pipeline, and the liquid outlet is connected to a reversible liquid pump connected to the source of the working fluid.

EFFECT: energy efficiency increases by reducing fluctuations in the power of the liquid pump, and, accordingly, the drive motor.
