Abstract

DE ACUERDO AL INVENTO SE OBTIENE UNA BOMBA (1) DE CHORRO CENTRIFUGA Y AUTO-ARRANCABLE, COMPRENDIENDO UN ALOJAMIENTO (2,30,40,50,60,70) DE BOMBA EL CUAL NO PRESENTA UNA FORMA ESPECIFICA EN ALGUNAS DE SUS SUPERFICIES CON CORTES INFERIORES Y EN LAS CUALES LA UNIDAD DE BOQUILLA DE EXPULSION (19) SE MONTA SOBRE SUS ASIENTOS (15,20,31,36,49,46,59,69,66,79,76), LOS CUALES SON COAXIALES CON LOS EJES (21) DE ROTACION DEL EXPULSOR (22). DICHA BOQUILLA (19) DE EXPULSION PRESENTA UN DIAFRAGMA (7,32,42,52,62,72), DISPUESTO TRANSVERSALMENTE, EL CUAL DIVIDE EL VOLUMEN INTERIOR DEL ALOJAMIENTO (2,30,40,50,60,70) DE LA BOMBA DE MODO QUE SE CREA UNA CAMARA DE SUCCION (3) Y UNA CAMARA DE PRESION (5) Y UN COLLAR DELANTERO (10,37, 47,57,67,77), EL CUAL SIRVE PARA DIVIDIR LA CAMARA DE SUCCION (3), DE MODO QUE SE CREE UN CANAL (24) Y UNA CAJA (11,35,45,55,65,75) DE ALTA PRESION PARA ALIMENTAR EL MEDIO DE IMPULSION DENTRO DE LA BOQUILLA (12), DISPUESTA EXCENTRICAMENTE EN EL COLLAR (10,37,47,57,67,77) CON UNA DISPOSICION ANTI REMOLINOS EN LA CAJA DE ALTA PRESION (11,35,45,55,65,75). EL CITADO (2,30, 40,50,60,70) ALOJAMIENTO DE LA BOMBA PRESENTA SU CONEXION (4,34,44,54,64, 74) DE SUCCION POSICIONADA EN EL EXTREMO DELANTERO DE LA BOMBA (1), SOBRE EL COLLAR (10,37,47,67,77) Y ESTA TOTAL O PARCIALMENTE CIRCUNSCRITA POR EL DIAFRAGMA (7,32,42,52,62,72).FIG 1.ACCORDING TO THE INVENTION, A CENTRIFUGAL AND SELF-STARTING JET PUMP (1) IS OBTAINED, INCLUDING A HOUSING (2,30,40,50,60,70) OF THE PUMP WHICH DOES NOT PRESENT A SPECIFIC FORM ON SOME OF ITS SURFACES WITH LOWER CUTS AND IN WHICH THE EXPULSION NOZZLE UNIT (19) IS MOUNTED ON ITS SEATS (15,20,31,36,49,46,59,69,66,79,76), WHICH ARE COAXIAL WITH THE AXIS (21) OF ROTATION OF THE EJECTOR (22). SUCH EXPULSION NOZZLE (19) PRESENTS A DIAPHRAGM (7,32,42,52,62,72), ARRANGED TRANSVERSALLY, WHICH DIVIDES THE INTERNAL VOLUME OF THE ACCOMMODATION (2,30,40,50,60,70) OF THE PUMP TO CREATE A SUCTION CHAMBER (3) AND A PRESSURE CHAMBER (5) AND A FRONT NECKLACE (10,37, 47,57,67,77), WHICH IS USED TO DIVIDE THE SUCTION CHAMBER (3 ), SO THAT A HIGH PRESSURE CHANNEL (24) AND A BOX (11,35,45,55,65,75) IS CREATED TO SUPPLY THE IMPULSION MEDIA INSIDE THE NOZZLE (12), PROVIDED EXCENTRICALLY ON THE NECKLACE (10,37,47,57,67,77) WITH AN ANTI-SWIRL PROVISION IN THE HIGH PRESSURE BOX (11,35,45,55,65,75). THE CITED (2,30, 40,50,60,70) ACCOMMODATION OF THE PUMP PRESENTS ITS CONNECTION (4,34,44,54,64, 74) OF SUCTION POSITIONED AT THE FRONT END OF THE PUMP (1), ON THE NECKLACE (10,37,47,67,77) AND IS TOTAL OR PARTIALLY CIRCUMSCRIBED BY THE DIAPHRAGM (7,32,42,52,62,72) .FIG 1.
