LUBRICATING SYSTEM OF GAS COMPRESSOR UNIT WITH STATIONARY GAS TURBINE ENGINE Russian patent published in 2021 - IPC F02C7/06 F16N31/02 

FIELD: machine building.

SUBSTANCE: invention can be used in gas pumping units. Lubrication system of gas transfer unit with stationary gas-turbine engine (5) contains oil tank (1) and connected to it blowing and drain pipelines and standard dynamic oil separator (7). In order to increase degree of oil purification oil tank (1) ventilation pipeline is fitted with oil-filter trap (8). Filter-oil trap (8) contains filter-cartridges intended for oil trapping. At inlet of oil-and-air mixture through inlet pipeline into housing of filter-oil trap and further at passing through self-cleaning filter-cartridges, separated oil enters oil tank (1) of gas transfer unit with gas turbine engine (5), and cleaned air through discharge pipeline will enter atmosphere. Filter-oil trap (8) creates resistance to oil-air mixture flow, which exceeds natural draft of standard ventilation system. Filter-oil trap (8) is fitted with ejector. Air to ejector is supplied from gas transfer unit or from fan (12).

EFFECT: technical result consists in elimination of oil emissions from oil tank of gas transfer unit and reduction of turbine oil consumption.
