Abstract

TURBINA QUE CONSTA DE AL MENOS UN PASO (20) CON UN DIAFRAGMA (2) CORTADO EN DOS SEGUN UN PLANO DIAMETRAL Y QUE COMPRENDE UN ACORONA EXTERIOR (3) Y UNA CORONA INTERIOR (6) UNIDAS ENTRE SI MEDIANTE UNOS ELEMENTOS (10 Y 11) QUE PROPORCIONAN EL GUIADO DEL FLUIDO DE LA TURBINA, ESTANDO LA CARA ANTERIOR (14) DE LA CORONA EXTERIOR (3) APLICADA CONTRA UNA CORONA (19) DEL ESTATOR (4) DE LA TURBINA, ESTANDO PROVISTO DICHO DIAFRAGMA (1) DE UN ELEMENTO DE ESTANQUEIDAD (17) QUE GARANTIZA LA ESTANQUEIDAD ENTRE L ACORONA EXTERIOR (3) Y EL ESTATOR (4). SE CARACTERIZA PORQUE DICHO ELEMENTO DE ESTANQUEIDAD (17) ESTA SITUADO EN EL TRAMO (15) DE LA CORONA EXTERIOR (3), PORQUE LA CARA ANTERIOR (14) DE DICHA CORONA EXTERIOR (3) ESTA PROVISTA DE UN APOYO (18) DISTANTE DEL TRAMO (15) Y QUE SE APOYA CONTRA LA CORONA (19) DEL ESTATOR (4) Y PORQUE HAY UNOS ELEMENTOS (22,27,27'') PARA GARANTIZAR UNA COMUNICACION DEL ESPACIO (25) SITUADO ENTRE EL APOYO (18) Y EL ELEMENTO DE ESTANQUEIDAD (17) CON UN ESPACIO EXISTENTE TRAS EL DIAFRAGMA (1), ESTANDO DICHO ESPACIO A UNA PRESION INFERIOR A LA PRESION P1 QUE HAY EN LA CARA ANTERIOR (26) DEL DIAFRAGMA (1)
