Abstract

CIERRE DE PRESA DOBLE EN UNA BOMBA ENFRIADORA DE REACTOR QUE INCLUYE UN MECANISMO INTERNO EN EL CIERRE PARA PRESIONIZAR SU CORONA CIRCULAR. EN UN MODO, EL MECANISMO ES UN CONDUCTO DE FLUJO INCLINADO INCORPORADO EN EL RODETE GIRATORIO DEL CIERRE QUE TIENE UN SALIDA EN COMUNICACION CON LA CORONA CIRCULAR DEL CIERRE Y UNA ENTRADA EN COMUNICACION CON EL FLUJO DE AGUA DE ENFRIAMIENTO PARA EL REACTOR DENTRO DEL ALOJAMIENTO DE LA BOMBA Y SITUADO EN UN RADIO DE ROTACION MEJOR QUE LA SALIDA DEL CONDUCTO. LA ROTACION DEL RODETE PROVOCA UN MOVIMIENTO GIRATORIO DEL CONDUCTO Y EL AGUA QUE SE ENCUENTRA EN EL MISMO, QUE VUELVE AL CONDUCTO Y EL RODETE GIRATORIO EN UNA BOMBA CENTRIFUGA, CREA UN DIFERENCIAL DE PRESION A LO LARGO DEL CONDUCTO DEBIDO A LOS EFECTOS CENTRIFUGOS, Y LA ALIMENTACION DEL AGUA A TRAVES DE LA SALIDA DEL CONDUCTO HACIA LA CORONA CIRCULAR DEL CIERRE A UNA PRESION SUPERIOR A LA DE LA ENTRADA DEL CONDUCTO. EN OTRO MODO, EL MECANISMO ES UN TUBO QUE SOBRESALE FORMANDO ANGULO DEL RODETE GIRATORIO, O UN CANGILON REBAJADO DEFINIDO EN EL RODETE FORMANDO ANGULO Y COMUNICANDOSE CON EL CONDUCTO QUE TIENE UNA ENTRADA Y UNA SALIDA CON EL MISMO RADIO DE ROTACION. EL TUBO O CANGILON TIENEN GENERALMENTE EL MISMO RADIO DE ROTACION PERO SE EXTIENDEN POR ENCIMA DE LA ENTRADA DEL CONDUCTO. EL MOVIMIENTO ROTACIONAL DEL TUBO O CANGILON CON EL RODETE GIRATORIO A TRAVES DEL AGUA DE ENFRIAMIENTO DEL REACTOR EN EL ALOJAMIENTO DEL CIERRE, DESARROLLA UNA PRESION MAYOR EN LA ENTRADA DEL CONDUCTO QUE EN LA SALIDA, LA CUAL, A SU VEZ, ES ALIMENTADA POR EL CONDUCTO A LA CORONA CIRCULAR DEL CIERRE DE PRESA DOBLE.
