Abstract

UNA BOMBA CENTRIFUGA DE AUTOCEBADO QUE INCLUYE UNA CAJA DE PLACAS METALICAS CILINDRICA (2) QUE FORMA UNA CAMARA DE PRESION (13, 13'', 13") Y QUE TIENE UN ORIFICIO DE ENTRADA DE SUCCION (5) Y UN ORIFICIO DE SALIDA DE PRESION (6). LA CAMARA DE PRESION (2) TIENE UN PROPULSOR CON ALABES (12) CON UN DIFUSOR COLOCADO EN LA PERIFERIA (17), UN DISPOSITIVO EYECTOR AXIAL (19) QUE INCLUYE UN TUBO DE VENTURI (20) Y UN ESPACIO INTERMEDIO TORICO PARA TRANSPORTAR EL FLUJO EMITIDO DESDE EL DIFUSOR RADIAL (17) HACIA LA CAMARA DE PRESION (13''). EN LA PORCION INFERIOR DEL ESPACIO INTERMEDIO (16) HAY COLOCADA UN SOLO ALABE CURVO (26) QUE SE EXTIENDE VERTICALMENTE DESDE LA REGION PERIFERICA DEL DIFUSOR RADIAL (17) HASTA UN PASO DE SALIDA ANULAR, CENTRAL (22) DEL ESPACIO INTERMEDIO (16) QUE SE EXTIENDE A TODO ALREDEDOR DE DICHO DISPOSITIVO EYECTOR (19) DE TAL MODO QUE CONTRARRESTA AL COMPONENTE ROTATIVO DE LA DIRECCION DE VELOCIDAD DEL FLUIDO Y FOMENTA LA SEPARACION DE AIRE.
