STEAM TURBINE

摘要

FIELD: thermal engineering. SUBSTANCE: steam turbine has multistage rotor 2 with disks 3 provided with releasing holes 4 and running blades 5. Turbine also has diaphragms 7 with nozzle blades 8 on rim forming nozzle ducts 11. Diaphragms are provided with labyrinth seals 9 in their central bores and ducts 12 communicating with nozzle ducts 11. Starting sections 13 of diaphragm central bores communicate with nozzle ducts 11 through ducts 12. EFFECT: improved economic efficiency of turbine. 1 dwgn
