Abstract
BOMBA IMPULSADA POR UN ELECTROMOTOR QUE FUNCIONA DE FORMA SINCRONA Y QUE MUESTRA UN ARBOL DE ROTOR (1) PARA SUMINISTRAR LIQUIDO A UNA RUEDA DE RODADURA (2) DE LA BOMBA QUE SE ENCUENTRA DISPUESTA EN UN EXTREMO DEL ARBOL DEL ROTOR. EL ESPACIO EN EL QUE ESTA DISPUESTO EL ESTATOR (8) Y EL ESPACIO EN EL QUE ESTA DISPUESTO EL ROTOR (6) ESTAN SEPARADOS ENTRE SI DE FORMA ESTANCA A LOS LIQUIDOS A TRAVES DE UN DIAFRAGMA (12) DE PLASTICO. LOS DIAFRAGMAS DE PLASTICO PRESENTAN LA VENTAJA DE QUE NO IMPIDEN EL FLUJO MAGNETICO ENTRE EL ESTATOR (8) Y EL ROTOR (6). PARA REALIZAR EL DIAFRAGMA (12) CON UN GROSOR DE PARED LO MAS PEQUEÑO POSIBLE, EL DIAFRAGMA (12) DEL INTERIOR DEL ESTATOR (8) SE REALIZA DE TAL FORMA, QUE SE APOYA EN LAS PRESIONES INTERNAS DEL ESTATOR (8). A FIN DE QUE EL DIAFRAGMA (12) TAMPOCO SE ROMPA EN LAS AREAS DE LOS BORDES (31, 32) EN LAS QUE NO ESTA SUJETADO POR EL ESTATOR (8), EL GROSOR DE LA PARED DEL DIAFRAGMA (12) ES MAYOR EN LAS AREAS (31, 32) EN LAS QUE SOBRESALE DEL ESTATOR (8) QUEEN EL AREA DEL ESTATOR (8).
