COMPRESSOR UNIT FOR COMPRESSION OF GAS OR GAS-LIQUID MIXTURE, WHICH IS INTENDED FOR THEIR PUMPING TO WELL OR PIPELINE Russian patent published in 2010 - IPC F04B19/06 F04B47/04 

FIELD: engines and pumps.

SUBSTANCE: unit includes beam-pumping unit 3, piston-type compressor 5 installed on frame, as well as system of pipelines integrating them. Under frame 4 of beam-pumping unit 3 of the first compression stage (module) of gas or gas-liquid mixture there fixed horizontally or with higher location of working zone, rigidly or freely to some extent is piston-type compressor 5 containing operating cylinder 7, suction valve 8, discharge valve 9, plunger 10 with polished stock 11. At that, working zone 12 of cylinder 7 of piston-type compressor 5 through suction valve 8 is connected to pipeline 13 of gas or gas-liquid low pressure mixture, and through discharge valve 9 of piston-type compressor 5 is connected in its turn to high pressure pipeline 14. If there is the second module in compressor unit, gas or gas-liquid mixture is supplied via high pressure pipeline 14 of the first compression stage to the second compression stage (to the second module) to piston-type compressor 24 of the second compression stage to working zone 26 of cylinder 25 through suction valve.

EFFECT: increasing efficiency and reliability of operation owing to increasing efficiency and reliability of operation of piston-type compressors intended for utilisation with any ratio of gas and liquid.
