Abstract

BOMBAS DE FLUIDO ROTATIVAS.LAS BOMBAS, DEL TIPO DE N, N B 1 LOBULOS TIENEN DOS ROTORES, INTERIOR (10) Y EXTERIOR (14) SITUADOS EXCENTRICAMENTE Y RADIALMENTE MOVILES UNO RESPECTO AL OTRO AUNQUE EN GRADO LIMITADO, DE FORMA QUE SE COMPENSEN LA HOLGURA EXISTENTE EN LAS BASES DEL ROTOR EXTERIOR (22), SUPERIOR A LA DE FUNCIONAMIENTO NORMAL, PARA LA ELIMINACION DE SUCIEDADES CONTENIDAS EN EL LIQUIDO BOMBEADO, CON LA EXISTENTE EN LA ZONA OPUESTA (32) DE ENGRANE TOTAL, YA QUE ESTA SE MANTIENE DENTRO DE LOS LIMITES DE HOLGURA DE FUNCIONAMIENTO NORMAL,NO SUPERIOR A 0,14 MM, LOGRANDOSE ASI UNA MAYOR EFICACIA VOLUMETRICA DE LA BOMBA. LA BASE ENTRE LOBULOS DEL ROTOR EXTERIOR (14) ES DE CONFIGURACION SEMICILINDRICA, Y EL ROTOR INTERIOR PUEDE TENER UN NUMERO PAR O IMPAR DE LOBULOS. EL ROTOR EXTERIOR (14) ESTA MONTADO EN UNA CARCASA CON LA HOLGURA SUFICIENTE PARA PERMITIR EL MOVIMIENTO RADIAL ENTRE ROTORES.
