Abstract

EL GRUPO BOMBA SUMERGIBLE SE COMPONE EN ESENCIA DE UN MOTOR ELECTRICO (1) Y DE UNA BOMBA CENTRIFUGA ACCIONADA POR EL, LOS CUALES ESTAN MONTADOS CON EL MISMO EJE EN UNA CARCASA COMUN (2). EL GRUPO TIENE UNA ABERTURA DE ENTRADA (15) Y UNA ABERTURA DE SALIDA FORMADA COMO MANGUITO DE PRESION (16). CONCENTRICA CON EL RODETE (10) ESTA UNA PARED DE LA CARCASA (21) QUE LA RODEA, LA CUAL TIENE UN ABOMBAMIENTO (18), QUE FORMA UNA ZONA DE RETENCION PARA EL FLUJO EN EL LADO DE PRESION. EN LA PARTE DE ESTA ZONA DE RETENCION SE UNE UN CANAL CONDUCTOR (17) HACIA EL MANGUITO DE PRESION (16), POR EJEMPLO, EN FORMA DE UN TUBO.THE SUBMERSIBLE PUMP GROUP IS COMPOSED IN ESSENCE OF AN ELECTRIC MOTOR (1) AND A CENTRIFUGAL PUMP OPERATED BY IT, WHICH ARE ASSEMBLED WITH THE SAME AXLE IN A COMMON HOUSING (2). THE GROUP HAS AN INLET OPENING (15) AND AN OUTLET OPENING FORMED AS A PRESSURE SLEEVE (16). CONCENTRATED WITH THE IMPELLER (10) IS A WALL OF THE HOUSING (21) WHICH SURROUNDS IT, WHICH HAS A CUP (18), FORMING A RETAINING ZONE FOR THE FLOW ON THE PRESSURE SIDE. IN THE PART OF THIS RETENTION AREA, A CONDUCTIVE CHANNEL IS JOINED (17) TO THE PRESSURE SLEEVE (16), FOR EXAMPLE, IN THE FORM OF A TUBE.
