Abstract

LA INVENCION SE REFIERE A UN TURBINA DE VAPOR CON UN EJE (3) QUE, AL MENOS SOBRE PARTE DE SU LONGITUD, ESTA LOCALIZADO EN UNA CARCASA (4) A TRAVES DE LA CUAL PASA, SIENDO UNO DE LOS EXTREMOS DE LA CARCASA (4), EL EXTREMO (10) ESTANCO A LA PRESION Y EL EXTREMO OPUESTO EL EXTREMO (12) DE EXAHUSTACION DE VAPOR. ADICIONALMENTE, LA CARCASA INCORPORA UNA VALVULA (30) DE CONTROL DISEÑADA PARA CONTROLAR LA RELACION DE FLUJO DE VAPOR DENTRO DE LA CARCASA (4). LA INVENCION PROPONE QUE LOS COJINETES DEL EJE GIREN DE FORMA SECA, SIENDO CONSEGUIDO ESTO MEDIANTE LA UTILIZACION DE COJINETES (6,8,14) MAGNETICOS LOCALIZADOS DENTRO DE LA CARCASA (4) EN EL EXTREMO (10) DE ALTA PRESION Y EN EL EXTREMO (12) DE EXHAUSTACION DE VAPOR. LA INVENCION SE REFIERE TAMBIEN A LA OPERACION DE VALVULA DE CONTROL DE FORMA QUE SE ENCUENTRE LIBRE DE ACEITE, CONSIGUIENDOSE POR MEDIO DE LA UTILIZACION DE UN ACTUADOR (28) ELECTROMAGNETICO.
