FIELD: heat power engineering; production and reconstruction of steam turbines.
SUBSTANCE: proposed invention makes it possible to increase ecological and fire safety, provide reliability and high quality of operation of bearing lubrication system and steam turbine control system by eliminating penetration of oil aerosols into engine room and getting of oil onto steam turbine insulation, to prevent contamination of oil with water and provide reliability separation of steam-water and oil media and reliable transportation of ejected products of separated media into drain spaces and their reliable removal along outer utilization system. According to invention, impeller pump wheel is installed between steam baffle and oil control plates, and vertical ring groove is made from outer side of main disk in which separating ring of seal holder is fitted.
EFFECT: improved ecological and fire safety.
