SYSTEM OF TURBOCOMPRESSOR SEALS Russian patent published in 2009 - IPC F04D29/10 

FIELD: machine building.

SUBSTANCE: invention is related to sealing engineering, may be used in systems of seals of turbocompressors of different purpose, in particular in sealing systems of gas pumping units. Specified technical result is achieved in sealing system of turbocompressor shaft comprising end gas seals, double-stage labyrinth seals, between stages of which leveling chambers are installed, and line of gas supply in chambers between end and labyrinth seals, in which filters are installed, as well as flow limiter arranged in the form of pressure difference controller. System is equipped with valve 11 for emergency air exhaust, which is connected to leveling chambers 7 between stages of labyrinth seals 4, at that valve drive is connected to high pressure alarms 14 in lines 12 for leaks drain downstream the first stages of end seals, and cavity of pressure difference controller setting pressure is connected to leveling chambers, which are installed between stages of labyrinth seal by separate pipeline.

EFFECT: increased reliability and efficiency of operation, due to additional installation of emergency gas exhaust valve in sealing system.
