FIELD: machine building.SUBSTANCE: in axial-centrifugal compressor, the rotor of which includes impeller (6), axial gap (8) is adjusted by special air ventilation in the rotor, with a device containing two parallel channels (11, 13), in which flow velocities are adjusted with corresponding valves (12, 14). At that, temperature in one of them is changed by heat exchanger (15). Thus, adjustment of temperature and flow velocity of ventilation air is performed.EFFECT: providing adjustment of an axial gas in an extended section of an axial-centrifugal compressor due to difference of thermal deformations. |
