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.A SUBMERGED CENTRIFUGAL PUMP, OF THE CLOSED ROTATING CROWN (14) TYPE, IS PARTICULARLY USED FOR THE EXTRACTION OF FLUIDS CONTAINING SAND, EARTH AND / OR SMALL RESIDUES FROM UNDERGROUND WELLS. EACH STAGE (4) OF THE PUMP INCLUDES A CHAMBER, INSIDE OF WHICH IS CONTAINED A ROTATING CROWN (14) OF PALLETS, CONSISTING OF A LID (11), A CYLINDRICAL HOLLOW STATIONARY ELEMENT AND A DIFFUSER (1 3) OF FIXED PALLETS. BETWEEN CROWN (14) AND COVER (11) WATERTIGHT MEANS (15, 16) ARE INTERPOSED, WILLING AND CONFORMED TO PREVENT THE INFILTRATION BETWEEN IF OF SOLID SUSPENSIONS PRESENT IN THE FLUID.
