FIELD: energy industry.SUBSTANCE: turbo unit of gas-compressor unit (GCU) or gas turbine power plant (GTPP) comprises a gas turbine engine (GTE), a casing of the gas turbine engine, a compressor (blower) with labyrinth shaft seals, a transmission, a transmission casing with flanges, located between the casing of the gas turbine engine and the compressor. The transmission casing is provided with the inner wall forming the air duct together with its outer wall, which connects the casing cavity of the gas turbine engine with the area in front of the labyrinth compressor seals through the openings formed in the flange of the transmission casing, and the openings formed in the inner wall of the transmission casing, connected to it through the radial channel formed by the partitions fastened to the inner wall of the casing.EFFECT: use of the proposed invention enables to increase pressure in the exhaustion area in front of the compressor seals that will prevent the penetration of oil and its vapour from the compressor into the cavity of the casing of GTE and will prevent occurrence of emergencies.5 dwg |
