摘要： The invention discloses a seal structure and a control method therefor that can improve sealing performance between a rotating portion and a fixed portion, smoothly start up a steam turbine (2), and suppress the temperature rise of the rotating portion even if the rotating portion is continuously rotated for a long period of time.
A seal structure is configured such that seal fins (62) on a seal base-plate (61) side and corresponding breathable spacers (4b) on a rotor (2a) side are opposed to each other and breathable spacers (4a) on the seal base-plate (61) side and corresponding seal fins (2a1) on the rotor (2a) side are opposed to each other. The seal base-plate (61) is installed shiftably in a direction coming close to or moving away from the rotor (2a). If steam St has low pressure, the seal fins (62) and the corresponding breathable spacers (4b) are not in contact with each other and the seal fins (2a1) and the corresponding breathable spacers (4a) are not in contact with each other. If the steam St has high pressure, the seal fins (62) and the corresponding breathable spacers (4b) are in contact with each other and the seal fins (2a1) and the corresponding breathable spacers (4a) are in contact with each other.摘要翻译： 本发明公开了一种密封结构及其控制方法，其能够改善旋转部分和固定部分之间的密封性能，平稳地启动蒸汽涡轮机（2），并且即使旋转部分 不断旋转很长一段时间。 密封结构被构造成使得密封基板（61）侧上的密封翅片（62）和转子（2a）侧上的对应透气间隔件（4b）彼此相对，并且密封件上的可透气间隔件（4a） 转子2a侧的基板61侧和对应的密封翅片2a1彼此相对。 密封底板（61）沿着接近或远离转子（2a）的方向可移动地安装。 如果蒸汽St具有低压，则密封翅片62和相应的透气垫片4b不相互接触，并且密封翅片2a1和相应的透气垫片4a不相互接触 。 如果蒸汽St具有高压，则密封翅片62和相应的透气间隔件4b彼此接触，并且密封翅片2a1和相应的透气间隔件4a彼此接触。
