METHOD FOR AUTOMATICALLY ADJUSTING STEAM FEED PUMP NEAR CRITICAL POINT AT WHICH RECIRCULATION VALVE IS OPENED

Disclosed is a method for automatically adjusting a steam feed pump near a critical point at which a recirculation valve is opened, comprising the following steps: in response to reaching a critical point at which recirculation valves of two steam feed pumps are opened at the same time, setting a rotating speed offset for one of the steam feed pumps, such that the inlet flow of the corresponding steam pump is slowly increased; and far away from the critical point at which the corresponding recirculation valve is opened, only allowing the corresponding recirculation valve of the other steam feed pump to be slowly opened. L'invention divulgue un procédé de réglage automatique d'une pompe d'alimentation en vapeur à proximité du point critique d'ouverture de la soupape de recirculation, comprenant les étapes suivantes : en réponse à l'atteinte d'un point critique au niveau duquel des soupapes de recirculation de deux pompes d'alimentation en vapeur sont ouvertes en même temps, régler un décalage de vitesse de rot
