Title: Sealing structure for steam turbine
Inventor: NARITA KENJIRO
IPC: F01D11/02
Filed: 2011-01-14
Abstract: PROBLEM TO BE SOLVED: To improve sealing performance between a rotating region and a fixed region, to prevent fins from being damaged, and to prevent increases in the amount of steam leakage from any clearances newly formed by further abrasion of an abradable material.SOLUTION: In the sealing structure, free-cutting spacers 28 on a sealing base plate 25 and sealing fins 24 on a rotor 18 are opposed to each other. The sealing base plate 25 is disposed so as to be movable in an axial direction of the rotor 18. When a steam turbine increases in load, a pressure head 30 receives a pressure in rotor diameter direction which is converted into a pressure in rotor axial direction by a slope. A move support 40 having received the pressure in the rotor axial direction moves in a rotor axial direction. The sealing base plate 25 supported by the move support 40 is driven in the rotor axial direction. Since the free-cutting spacers 28 at positions opposed to those of the sealing fins 24 existing after the movement of the sealing base plate are maintained in a noncontact state, clearances between the sealing fins 24 and the free-cutting spacers 28 are dimensionally minimized.
