Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE REFRIGERACION (1) CON ACCIONAMIENTO ELECTRICO, CON UN ROTOR (2) RODEADO POR UN ESTATOR (12) DEL MOTOR ELECTRICO (13), CON UN EJE DE ROTOR HUECO (4) A TRAVES DEL CUAL SE EFECTUA LA ALIMENTACION DE LIQUIDO HACIA EL RODETE DE LA BOMBA (5), ESTANDO DISPUESTO EL ESTATOR (12) EN UNA CAMARA DE ESTATOR (11) DE LA CARCASA DEL MOTOR (3), Y ESTANDO APOYADO EL EJE DEL ROTOR (4) GIRATORIO EN LA CARCASA DEL MOTOR (3), EFECTUANDOSE EL APOYO DEL EJE DEL ROTOR (4) MEDIANTE COJINETES DE RODAMIENTO (7, 8). PARA INCREMENTAR EL GRADO DE RENDIMIENTO Y REDUCIR EL DESGASTE EN LOS COJINETES SE PROPONE QUE POR LO MENOS UNO DE LOS COJINETES DE RODAMIENTO (7, 8) SEA UN COJINETE DE RODAMIENTO ESTANCO A LOS LIQUIDOS, Y QUE HAYA UNOS ELEMENTOS DE JUNTA (9, 10) INTEGRADOS EN LA JAULA DEL COJINETE DE RODAMIENTO (7A, 8A), Y QUE LA CAMARA DEL ESTATOR SEPARADA ESTANCA A LOS LIQUIDOS CON RESPECTO AL LIQUIDO IMPULSADO, SEA UNA CAMARA SECA.
