Abstract

EL PRESENTE INVENTO SE REFIERE A UN DIFUSOR DE UN COMPRESOR CENTRIFUGO PARA GUIAR UN FLUIDO QUE FLUYE DESDE UN IMPULSOR (1) A UN CARACOL (4). EL DIFUSOR SE FORMA MEDIANTE UN PAR DE PAREDES LATERALES DISPUESTAS OPUESTAMENTE (2), (3). EL DIFUSOR DISPONE EN SU PORCION DE SALIDA DE FLUIDO (7) DE UNA PORCION DE CEBADO DE SALIDA (7A). ESTA PORCION DE CEBADO DE SALIDA (7A) SE FORMA ENANGOSTANDO GRADUALMENTE EL ANCHO DEL PASAJE CORRIENTE ABAJO DESDE UN PUNTO DE COMIENZO (10) QUE SE UBICA EN UNA POSICION EN LA QUE LA PRESION DE FLUIDO DINAMICO SE CAMBIA CASI PERFECTAMENTE A UNA PRESION ESTATICA. AL PROVEER LA PORCION DE CEBADO DE SALIDA (7A) SE DISMINUYE EL RIESGO DE PERDIDA DE PRESION, SE LIMITA LA POSIBILIDAD DE SEPARACIONES DE FLUJO E SE IMPIDE QUE EL FLUIDO FLUYA EN REVERSO DESDE EL CARACOL (4). ESTO RESULTA EN UNA MEJORA EN LA LINEA DE DISCONTINUIDAD Y EN LA EFICIENCIA DE CARGA PARCIAL.
