Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE VACIO GIRATORIA IMPERMEABLE AL ACEITE CON UNA CAMARA DE SUCCION (8), CON UN ROTOR (3) DISPUESTO DE FORMA GIRATORIA EN LA CAMARA DE SUCCION, QUE ESTA EQUIPADO CON UN SEGMENTO DE ANCLAJE (21) Y UN SEGMENTO DE COJINETE (23), CON UNA RANURA DE CORREDERA (24) PREVISTA EN EL SEGMENTO DE ANCLAJE, CON DOS CORREDERAS (26) DISPUESTAS EN LA RANURA DE CORREDERA QUE FORMAN ENTRE ELLAS UNA CAMARA INTERMEDIA DE CORREDERA (28), CON UN ALOJAMIENTO PARA EL ROTOR (3) QUE COMPRENDE EL SEGMENTO DE COJINETE (23) Y UN TALADRO DE COJINETE (11), CON UNA BOMBA DE ACEITE (45, 46) PARA GENERAR UNA CORRIENTE DE ACEITE QUE ATRAVIESA LA CAMARA INTERMEDIA DE CORREDERA (28) Y CON UN CONTROL PARA EL ACEITE QUE ATRAVIESA LA CAMARA INTERMEDIA DE CORREDERA (28), A TRAVES DE UN CANAL DE ACEITE (66) QUE DESEMBOCA EN EL TALADRO DE COJINETE (11) Y, A TRAVES DE TALADROS RADIALES Y AXIALES (68, 69), EN EL SEGMENTO DE COJINETE (23); PARA REDUCIR LOS RUIDOS DE FUNCIONAMIENTO DE LA BOMBA DE VACIO,SE PROPONE QUE LA POSICION DE LAS DESEMBOCADURAS DEL CANAL DE ACEITE (36) QUE DESEMBOCA EN EL TALADRO DE COJINETE (11), POR UN LADO, Y DEL TALADRO RADIAL (68) EN EL SEGMENTO DE COJINETE (23), POR EL OTRO, EN RELACION A LA POSICION DE LA CORREDERA (26) O DE LA RANURA DE CORREDERA (24), SE ELIJA DE TAL MANERA QUE EL ACEITE SOLO ENTRE EN LA CAMARA INTERMEDIA DE CORREDERA (28), CUANDO ESTA AUMENTE SU VOLUMEN, Y QUE PARA EL ACEITE QUE ABANDONA LA CAMARA INTERMEDIA DE CORREDERA (28) SE PREVEA UNA UNION ABIERTA PERMANENTEMENTE, QUE CONDUCE A LA CAMARA DE SUCCION (8).
