Shaft seal structure and turbine |
摘要 |
The shaft seal structure is based on a leaf seal that includes springs, disposed between the stator blades and the leaf seal ring, to force the leaf seal ring away from the rotation shaft, and pressure guiding grooves for guiding the fluid pressure, through a boundary of planar plates, to a space between the outer peripheral surface of the leaf seal ring and the inner peripheral surface of the stator blade. Also, a turbine may be provided with the leaf seal so as to reduce gas leakage from the high-pressure-region to the low-pressure-region as well as to control the frictional wear between the planar plates and the rotation shaft.
