Abstract
BOMBA DE CHORRO, CON JUNTA DE LABERINTO, PARA SISTEMA DE REFRIGARACION DEL NUCLEO DE UN REACTOR NUCLEAR. COMPRENDE UN MEZCLADOR UNIDO, MEDIANTE LA JUNTA DESLIZANTE (11), A UN DIFOSOR (63). DICHA JUNTA, QUE PERMITE UNA DILATACION TERMICA DIFERENCIAL Y FACILITA EL DESMONTAJE Y MANTENIMIENTO DE LAS SECCIONES DE LA BOMBA, ESTA CONSTITUIDA POR LAS PORCIONES (12,13) EN LOS EXTREMOS INFERIOR DE MEZCLADOR Y SUPERIOR DE DIFOSOR, RESPECTIVAMENTE. EL ESPACIO ANULAR DE HOLGURA ENTRE LAS PORCIONES DE JUNTA, QUE TIENE FORMA DE LABERINTO DEBIDO A LOS CANALES (17) DEL MEZCLADOR, REDUCE LA VIBRACION DEBIDA A LAS FUGAS. EN UNA VARIANTE, LOS SURCOS (17) PUEDEN SITUARSE EN EL DIFUSOR.
