TURBINE PLANT WITH PUSHER AND PUSHER FOR SUCH PLANT Russian patent published in 2002 - IPC

FIELD: power engineering. SUBSTANCE: turbine plant is designed for use in steam-turbine plant containing at least two partial-admission turbines 2, 3a, 3b, 3c, each provided with turbine rotor 5 passing along main axis 4, and inner housing 7, 8a, 8b, 8c accommodating guide vanes 6. At least one of inner housing 8a, 8b, 8c is made for shifting in axial direction for this purpose pusher 9 is used which elongates under action of temperature. Pusher 9 has first elongating member 10a and second elongating member 10b interconnected by member 11. Said connecting member 11 provides axial shifting of second elongating member 10b mechanically or hydraulically. Axial shift of second elongating member exceeds temperature elongation and/or main shift of first elongating member 10a. EFFECT: provision of minimum axial clearance between rotor and inner housing of turbine. 7 cl, 3 dwg
