Abstract

Una turbina de vapor incluye un eje giratorio el cual se configura para girar alrededor de un eje, un álabe el cual se proporciona sobre una superficie periférica externa del eje giratorio, una cubierta la cual cubre el eje giratorio y el álabe desde un lado periférico externo, una veleta la cual se proporciona sobre una superficie periférica interna de la cubierta y un dispositivo de sellado el cual incluye un anillo de sellado proporcionado entre la superficie periférica externa y la veleta y una porción de ajuste de posición configurada para ajustar una posición del anillo de sellado en una dirección radial. Un método de ajuste de espacio del sello incluye un paso de medición para medir la longitud del anillo de sellado en la dirección radial desde una posición de referencia predeterminada como una longitud de referencia, un paso de preparación para preparar un anillo de sellado sin usar y un paso de ajuste para ajustar una longitud del anillo de sellado sin usar desde la posición de referencia hacia la longitud de referencia por la porción de ajuste de posición.
