Title:
蒸気タービン用ブラシシール
Document Type and Number:
Japanese Patent JP4624630
Kind Code:
B2
Abstract:
A number of sealing segments (20) mounts a brush seal about a rotor. The tips of the brush seal (46) are maintained out of contact with the rotor surface throughout the entire operating range of the turbomachinery. Thus, the increase in temperature resultant from rubs between the bristle tips and the rotor (12) which effectively increase vibrations of the turbomachinery are eliminated. Brush seals are therefore maintained out of contact with the rotor throughout the entire operating range of the turbomachinery and thus do not affect the dynamic behavior of the rotor.
