Abstract
EN UNA TURBINA DE VAPOR, UN ANILLO (36) DE ALABES ESTACIONARIOS, QUE NORMALMENTE ESTA SOSTENIDO SOBRE UNA PARED RADIAL DE UNA ENVUELTA INTERIOR (30) DE LA TURBINA, ES SOSTENIDO SOBRE UN ANILLO (34) DE ALABES SEPARADO DE AGUAS ARRIBA, DE MODO QUE EL ANILLO (36) DE ALABES ESTACIONARIOS QUEDA SEPARADO DE LAS INDESEABLES DEFORMACIONES TERMICAS QUE OCURREN NATURALMENTE EN LAS ESTRUCTURAS DE ENVUELTA INTERIOR DE LA TURBINA. EL ANILLO (36) DE ALABES ESTACIONARIOS DE AGUAS ABAJO ESTA FIJO AL ANILLO (36) DE ALABES DE AGUAS ARRIBA Y LA UNION SE EFECTUA UTILIZANDO UNOS PERNOS DE CONEXION (44) Y PASADORES O CLAVIJAS DE ALINEACION. LA DISPOSICION ES COMPACTA Y DE BAJO COSTE Y REDUCE LAS FUGAS EN LOS OBTURADORES DEL RECORRIDO DE ALABES.
