Abstract

UN CUERPO (9) DE UN VOLUMEN DADO QUE SE CONTROLA PARA MOVER EL CODO (8) DEL DIFUSOR (7) DE UNA TURBINA TIPO FRANCIS PARA HACER QUE VARIE EL VOLUMEN DEL DIFUSOR (7) Y UN CONDUCTO AUXILIAR (23) CON UNA CAPACIDAD CONSTANTE DE CONDUCCION SE EXTIENDE PARALELO AL DIFUSOR (7), DESDE LA REGION DEL CODO (8) HASTA LA REGION QUE SE ENCUENTRA ADYACENTE AL DEPOSITO PIEZOMETRICO (21), PARA INTRODUCIR MEDIANTE LA UTILIZACION DE UNA VALVULA CONTROLADA (25) UNA CORRIENTE DE AGUA CONTROLADA, ADICIONAL (QO + Q) EN EL CODO (8) DEL DIFUSOR (7), EN DONDE EL USO DE DICHO CUERPO MOVIL (9) Y/O DE DICHO CONDUCTO AUXILIAR (23) TIENE COMO OBJETIVO REDUCIR A UN MINIMO (7) LOS CONSTANTES IMPULSOS DE PRESION QUE TIENEN LUGAR EN EL DIFUSOR MANTENIENDO ASI LA VELOCIDAD DE FLUJO, EL INTERVALO, EL PAR Y LA POTENCIA DEL ROTOR (3) DE LA TURBINA.
