Abstract

ESCALON DE TURBINA QUE COMPRENDE UNA REJILLA DE ALABES FIJAS (1) SOLIDARIA DEL ESTATOR (3) DE LA TURBINA QUE SOPORTA UN DIAFRAGMA SEGUIDA DE UNA REJILLA DE ALABES MOVILES (7) MONTADA SOBRE UN DISCO (9) SOLIDARIO DEL ROTOR (6) DE LA TURBINA, COMPRENDIENDO DICHA REJILLA DE ALABES MOVILES EN SU PARTE SUPERIOR UN HERRAJE DE ESTANQUEIDAD (10) CONSTITUIDO POR VARIAS RAMAS (11). EL DISCO (9) COMPRENDE ORIFICIOS DE ASPIRACION (16) QUE DESEMBOCAN EN EL ESPACIO QUE HAY ENTRE EL DIAFRAGMA (4) Y EL DISCO Y DISPUESTOS CERCA DE LA PARTE PERIFERICA DEL DISCO (9). LOS ORIFICIOS DE ASPIRACION (16) ESTAN CONECTADOS POR CANALIZACIONES (17) QUE ATRAVIESAN AL MENOS ALGUNOS ALABES MOVILES (8) HASTA UNOS ORIFICIOS DE SALIDA (18) QUE DESEMBOCAN EN LA PARTE SUPERIOR DE ESTOS ALABES (8) POR DEBAJO DEL HERRAJE DE ESTANQUEIDAD (10) O EN UNA CAMARA DE ESTE (11). LA CIRCULACION PERTURBADA A LOS PIES DE LOS ALABES FIJOS (2) Y LA CIRCULACION DE FUGA ENTRE EL DIAFRAGMA (4) Y EL ROTOR (6) SON ASPIRADOS POR LOS ORIFICIOS (16), LO QUE MEJORA EL RENDIMIENTO.
