Abstract

Se describe un alojamiento de sello entre etapas para un motor de turbina que tiene alojamientos de sello entre etapas superior e inferior en los cuales una superficie de sellado por contacto del alojamiento de sello se restablece después de un intervalo de operación del motor. La superficie de sellado por contacto se restablece al ajustar una tira de desgaste reemplazable en la superficie de sellado corriente abajo del alojamiento de sello. Para ajustar la tira de desgaste reemplazable, una ranura circunferencial es maquinada a lo largo de un borde periférico exterior del alojamiento de sello. La ranura es maquinada para incluir ubicación axial y retención radial de tal manera que las tiras de desgaste puedan ser deslizadas en el alojamiento de sello entre etapas de mitad superior y mitad inferior circunferencialmente desde la unión horizontal. La ranura incluye orificios de paso y las tiras de desgaste incluyen orificios roscados correspondientes de tal manera que las tiras de desgaste puedan ser sujetadas en la ranura por sujetadores y hardware de retención de sujetador.
