Abstract

JUNTA EMPERNADA DE PLANO DOBLE PARA CONJUNTOS SEGMENTARIOS DE ALABES FIJOS DE TURBINA SOPORTADOS SEPARADAMENTE. SE DESCRIBE UNA TURBINA DE VAPOR QUE ELIMINA LA TRANSFERENCIA DE DEFORMACION TERMICA DESDE EL CILINDRO INTERIOR A LOS CONJUNTOS DE ALABES FIJOS. UNA CONEXION EMPERNADA DE PLANO DOBLE Y UN INTERFAZ FLOTANTE LIBREMENTE DE LENGUETA Y ACANALADURA, FORMADOS ENTRE EL ANILLO EXTERIOR DE LOS CONJUNTOS DE ALABES FIJOS Y EL CILINDRO INTERIOR DE TURBINA, PROPORCIONAN LA HOLGURA NECESARIA PARA ELIMINAR LA DEFORMACION ASOCIADA CON LOS CONJUNTOS DE ALABES FIJOS MIENTRAS LOS SOPORTA DENTRO DEL CONJUNTO DE TURBINA. EL ANILLO EXTERIOR DE LOS CONJUNTOS DE ALABES FIJOS PUEDE SER FORMADO COMO UN COMPONENTE INTEGRAL O FORMADO POR DOS SECCIONES QUE DESPUES SON SOLDADAS ENTRE SI. LOS ALABES ROTATIVOS DE LA TURBINA ESTAN SITUADOS MUY PROXIMOS AL ANILLO EXTERIOR DE LOS CONJUNTOS DE ALABES FIJOS Y LA GUIA DE FLUJO ESTA COLOCADA EN EL ANILLO EXTERIOR.
