FIELD: mechanical engineering; turbines.
SUBSTANCE: invention relates to systems for adjusting seals and providing supply of oil to turbo-expanders. In proposed system for removal of gas-polluted oil from seals of turbo0expander, injector is installed in line along which gas-polluted oil is removed from float chambers into gas separator. Oil line from turbo-expander lubrication seal system is laid to nozzle of injector. Placed in said oil line are check valve and through valve installed in series with oil line from impeller charge laid additionally to through valve with possibility of delivery of lubricating oil to injector nozzle at starting and cutting off oil delivery to injector nozzle when turbo-expander attains operating mode. Invention improves reliability of operation of turbo-expander seal system owing to mounting suction injector with through and check valves at gas-polluted oil drain from float chambers.
EFFECT: improved reliability of turbo-expander seal system.
