Abstract

SE PRESENTA UN ESTATOR PARA BOMBA TURBO-MOLECULAR EN EL QUE CADA DISCO ESTATOR TIENE UNA FORMA FRUSTOCONICA PARA LA ORIENTACION INCLINADA DE LAS HOJAS (4, 4A), DICHO ESTATOR ESTA DIVIDIDO EN DOS PARTES SEMICIRCULARES (1, 2) QUE TIENEN UNAS LENGUETAS DE SUJECCION (12, 12A) EN SU INTERIOR, Y ESTA EQUIPADO A LO LARGO DE SUS BORDES EXTERIORES CIRCULARES (6, 6A) CON LENGUETAS RADIALES (120, 10A) QUE SE PROYECTAN PARA SUJETAR EL DISCO ESTATOR ENTRE DOS ANILLOS ESPACIADORES ADYACENTES (18). GRACIAS A ESTA CARACTERISTICA LA CORRIENTE DE RETORNO DE GAS QUE PODRIA ESTABLECERSE A TRAVES DE LOS INTERSTICIOS (20) ENTRE EL ESTATOR Y EL ALOJAMIENTO DE LA BOMBA (13) Y QUE PODRIA DIRIGIRSE HACIA EL LADO DE SUCCION DE LA BOMBA, PUEDE ALCANZAR EL ESPACIO INTERIOR DEL ESTATOR Y DE ESTA MANERA SER BOMBEADA HACIA AFUERA.
