Abstract

GUIA DE ADMISION DE FLUJO PARA UNA TURBINA DE VAPOR DE BAJA PRESION QUE INCLUYE UN ALOJAMIENTO GENERALMENTE CILINDRICO Y UN PAR OPUESTO DE REDES ANULARES DE ALABES QUE TIENEN UN PAR DE ALABES FIJOS ENFRENTADOS DISPUESTOS EN EL INTERIOR DEL ALOJAMIENTO. DICHA GUIA (1) INCLUYE UNA PLACA DE REFUERZO (43), GENERALMENTE CILINDRICA, CON UNA PIEZA PUENTE (45) GENERALMENTE CILINDRICA, MIEMBROS DE UNION ALARGADOS (47), MIEMBROS DE ACOMODACION (79) Y MIEMBROS DE ESTANQUEIDAD (81) UNIDOS A ALABES FIJOS ENFRENTADOS (13, 15) DE LAS FILAS ANULARES DE ALABES DE TURBINA PARA BLOQUEAR LA CIRCULACION DEL VAPOR DE BAJA PRESION POR LOS ORIFICIOS DE LA PIEZA PUENTE, AL TIEMPO QUE SE PERMITE UN LIMITADO MOVIMIENTO RELATIVO ENTRE LAS DIVERSAS PARTES. EL INVENTO ES APLICABLE A GENERADORES DE ENERGIA ELECTRICA.
