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. Installation contains working chambers of high and low pressure, made in the form of partially filled with liquid underground vertical tanks with wellhead heads. Suction and discharge gas valves are installed respectively on low and high pressure gas pipelines connected to the cavities of the mouth heads of high and low pressure working chambers. Submersible pump is located in the low pressure working chamber. It contains an ejector, the nozzle of which is connected to the outlet of the submersible pump. Inlet of the mixing chamber through the suction gas valve is connected to the low pressure gas pipeline. Outlet of the mixing chamber is hydraulically connected to the working high-pressure chamber. Working chambers of low and high pressure communicate with each other by means of adjustable distribution devices installed respectively on the line informing the indicated chambers directly and on the line connecting the output of the submersible pump with the working chamber of high pressure.

EFFECT: energy efficiency is increased by reducing fluctuations in pump power and, consequently, the drive motor through the implementation of an ejector process, as well as reduced dimensions of the compressor unit.
