Abstract

UNA RUEDA MOTRIZ PARA IMPULSAR UN FLUIDO (100) EN UNA BOMBA CENTRIFUGA INCLUYE UN NUCLEO DEL RODETE (105) QUE TIENE UNA FORMA PARECIDA A UN DISCO CON UN CENTRO Y UN BORDE, UNA SIMETRIA CIRCULAR Y ESTA PROVISTO PARA SER IMPULSADO DE MODO GIRATORIO. UNA PRIMERA SERIE DE ALABES (110) DE BOMBA SOBRESALE PERPENDICULARMENTE DE UNA PRIMERA SUPERFICIE DEL NUCLEO Y SE EXTIENDE, EN FORMA RADIAL HACIA EL EXTERIOR DESDE UN LUGAR (210) CERCA DEL CENTRO DEL NUCLEO HASTA OTRO LUGAR (150) CERCA DEL BORDE DEL NUCLEO. ESTOS ALABES (110) PROPORCIONAN UNA ELEVADA CARGA DE PRESION CON UN PEQUEÑO DIAMETRO DE LA RUEDA. UNA SEGUNDA SERIE DE ALABES (120) DE ENTRADA SEPARADOS Y RETORCIDOS SOBRESALE TAMBIEN, DE MODO PERPENDICULAR, DE LA PRIMERA SUPERFICIE DEL NUCLEO Y SE EXTIENDE, DE FORMA RADIAL, HACIA EL EXTERIOR DEL LUGAR (210) CERCA DEL CENTRO DEL NUCLEO DESDE OTRO LUGAR (220) MAS CERCANO AL CENTRO DEL NUCLEO. LA SEGUNDA SERIE DE ALABES SEPARADOS (120), POR MEDIO DEL GIRO Y UNA PRESURIZACION PREVIA DEL FLUIDO, FACILITA UNA RUEDA MOTRIZ QUE TIENE UNA CAPACIDAD DE BOMBEO LIBRE DE CAVITACION, CON UNA BAJA ALTURA DE ASPIRACION NETA Y POSITIVA (NPSH). SE PUEDE UTILIZAR UNA GUARDA DELANTERA (180) QUE PROTEJA TOTAL O PARCIALMENTE LA PRIMERA Y/O LA SEGUNDA SERIE DE ALABES.
