OIL SYSTEM OF GAS TURBOCOMPRESSOR Russian patent published in 1994 - IPC

FIELD: oil systems of gas turbocompressors. SUBSTANCE: during operation of turbocompressor 1, oil from oil tank 2 flows to sealing oil pumps 4 and via pipe line 3 and then to filter 7 via pipe line 6. From filter 7 oil flows to chambers 9 and 10 of shaft tight seals 11 and 12 via pipe line 8 and then to oil chamber 14 of accumulator 15 via pipe line 13. Then oil is directed via pipe line 16 to oil chambers 17 of "oil - gas" pressure differential regulator 18 and after it oil flows to chambers 20 of oil cooler 21 via pipe line 19. From oil cooler 21 oil is fed via pipe line 22 through pressure regulator 23 and via pipe line 24 to bearings 25 and 26 wherefrom it is returned to oil tank 2 via pipe lines 27. Required pressure of oil is maintained in chambers 9 and 10 due to throttling of oil in regulator 18 to the pressure determined by regulator 23 which sets low pressure (through discharging part of oil via return pipe line 28) in pipe lines 19 and 22 and in chambers 20 of oil cooler 21 adequate for lubrication of bearings 25 and 26. EFFECT: enhanced efficiency. 2 cl, 1 dwg
