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

FIELD: machine building.

SUBSTANCE: invention relates to the field of compressor machines and can be used in the extraction of oil and gas. Compressor plant comprises working chamber made up of gas-liquid separator, reversible liquid pump and ejector. Ejector nozzle is hydraulically connected through check valve with source of working fluid and reversible liquid pump, which is equipped with controlled electric drive with frequency regulator, inlet of mixing chamber of ejector is connected via suction gas valve with low pressure gas line. Output of mixing chamber of ejector is connected by means of bypass pipeline to upper part of gas-liquid separator, outlet of which is connected via gas through pressure gas valve to high pressure gas line, and the liquid outlet is connected to a reversible liquid pump connected to the source of the working fluid. Gas-liquid separator is equipped with level gauge external chamber hydraulically connecting upper and lower parts of gas-liquid separator. Float is arranged in level gauge external chamber. On its outer wall there installed are two level sensors at a distance from each other corresponding to minimum and maximum allowable lower and upper positions of liquid level in gas-liquid separator. Sensors are connected via control unit with electric motor frequency regulator.

EFFECT: excluding gas ingress into flow part of liquid pump and liquid into high pressure gas line due to synchronization of operation of gas-liquid separator and reversible liquid pump with fluctuations of liquid level in gas-liquid separator.
