| description | A system and a method for measuring and adjusting rotor to stator clearances are disclosed, as well as a turbomachine embodying the system and method. In an embodiment, a turbomachine is assembled, including a stator having an upper and a lower stator shell, and a rotor disposed within the stator. A cold clearance between the rotor and the stator is determined at each of a plurality of clearance measurement points using an in situ clearance sensor system. Each of the clearance measurement points is axially spaced from each other clearance measurement point. The cold clearance between the rotor and the stator is adjusted based on the determined cold clearances, by displacing one of the upper stator shell or the lower stator shell relative to a foundation, thereby changing the shape of the upper stator shell or the lower stator shell to accommodate the rotor within the stator.
회전자 대 고정자 간극들을 측정하고 조정하기 위한 시스템 및 방법, 뿐만 아니라 이러한 시스템 및 방법을 실시하는 터보기계가 개시된다. 실시예에서, 위쪽 및 아래쪽 고정자 쉘을 갖는 고정자, 및 고정자 내에 배치되는 회전자를 포함하는 터보기계가 조립된다. 회전자와 고정자 사이의 냉간 간극이, 정 위치 간극 센서 시스템을 사용하여, 복수의 간극 측정 지점 각각에서 결정된다. 각각의 간극 측정 지점은 각각의 다른 간극 측정 지점으로부터 축방향으로 이격된다. 회전자와 고정자 사이의 냉간 간극은, 기초부에 대해 위쪽 고정자 쉘 또는 아래쪽 고정자 쉘 중 하나를 변위시킴에 의해, 이에 의해 고정자 내부에 회전자의 위치를 수용하기 위한 위쪽 고정자 쉘 또는 아래쪽 고정자 쉘의 형상을 변경하도록 함으로써, 결정된 냉간 간극에 기초하여 조절된다. |
