Abstract
DISPOSITIVO PARA ASEGURAR LA ESTANQUIDAD LONGITUDINAL DEL ARBOL DE UNA BOMBA EN CASO DE ROTURA DE LA UNTA DINAMICA QUE SEPARA LA CAMARA DE ALTA PRESION DE LA CAMARA DE BAJA PRESION. EN CASO DE ROTURA DE LA JUNTA (3), LA CAMARA (5) DEBE SOPORTAR LA ALTA PRESION DE LA CAMARA (4) Y EL CONDUCTO DE EVACUACION (6) RESULTA INOPERANTE, POR LO QUE EL FLUIDO A PRESION ESCAPA POR EL ESTRECHAMIENTO (11). PARA CONSEGUIR EVITAR ESTO SE DISPONE DE UN PISTON (12) Y MEDIOS PARA EL DESPLAZAMIENTO AXIAL DEL MISMO, DE TAL FORMA QUE DICHO PISTON ES APLICADO CONTRA LA CORONA (33), PREVISTA A TAL EFECTO EN EL ARBOL (1), COMPRIMIENDO UNA JUNTA TORICA (14) QUE REDUCE O SUPRIME EL ESCAPE DE FLUIDO. EL PISTON (12) ES DESPLAZADO MEDIANTE UNA FUENTE DE FLUIDO A PRESION CONECTADA AL CONDUCTO (15) QUE COMUNICA CON UNA CAMARA (16). UNA JUNTA TORICA (17) ESTATICA EVITA TODA MEZCLA DE LOS DIFERENTES FLUIDOS BAJO PRESION. ESPECIAL APLICACION EN LAS BOMBAS PRIMARIAS DE LOS REACTORES NUCLEARES.
