Abstract

DISPOSITIF DE REGULATION DES GROUPES DE BUSES D'INJECTION DE VAPEUR POUR LA COMMANDE DE TURBINES A VAPEUR. IL COMPREND UN REGULATEUR DU TYPE A REGLAGE PROPORTIONNEL OU PROPORTIONNEL INTEGRAL. UN SERVO-MOTEUR 14, 15, 16, 17 EST ASSOCIE A CHAQUE GROUPE DE BUSES I, II, III, IV POUR ACTIONNER UNE SOUPAPE 10, 11, 12, 13 D'ADMISSION DE VAPEUR. LES SERVO-MOTEURS SONT COMMANDES L'UN APRES L'AUTRE EN SEQUENCE. ILS COMMENCENT A OUVRIR OU A FERMER LA SOUPAPE ASSOCIEE LORSQUE LA SOUPAPE PRECEDENTE S'OUVRE OU SE FERME.STEAM INJECTION NOZZLE GROUPS REGULATION DEVICE FOR STEAM TURBINE CONTROL. IT INCLUDES A PROPORTIONAL OR INTEGRAL PROPORTIONAL ADJUSTMENT TYPE REGULATOR. A SERVO MOTOR 14, 15, 16, 17 IS ASSOCIATED WITH EACH NOZZLE GROUP I, II, III, IV TO ACTUATE A STEAM INTAKE VALVE 10, 11, 12, 13. THE SERVO-MOTORS ARE CONTROLLED ONE AFTER THE OTHER IN SEQUENCE. THEY START TO OPEN OR CLOSE THE ASSOCIATED VALVE WHEN THE PREVIOUS VALVE OPENS OR CLOSES.
