Abstract

UNA BOMBA CENTRIFUGA SUMERGIDA, DEL TIPO MUTIETAPAS DE CORONA (14) GIRATORIA CERRADA, ES UTILIZADA PARTICULARMENTE PARA LA EXTRACCION DE FLUIDOS QUE CONTIENEN ARENA, TIERRA Y/O PEQUEÑOS RESIDUOS DE POZOS SUBTERRANEOS. CADA ETAPA (4) DE LA BOMBA COMPRENDE UNA CAMARA, EN EL INTERIOR DE LA CUAL ES CONTENIDA UNA CORONA (14) GIRATORIA DE PALETAS, CONSTITUIDA POR UNA TAPA (11), UN ELEMENTO (12) ESCALONADO DE FORMA CILINDRICA HUECA Y UN DIFUSOR (1 3) DE PALETAS FIJAS. ENTRE CORONA (14) Y TAPA (11) SE INTERPONEN MEDIOS DE ESTANQUEIDAD (15, 16), DISPUESTOS Y CONFORMADOS DE MANERA A IMPEDIR LA INFILTRACION ENTRE SI DE SUSPENSIONES SOLIDAS PRESENTES EN EL FLUIDO.
