Title (EN) TIP BALANCE SLITS FOR TURBINES
(FR) FENTES D'ÉQUILIBRAGE DE POINTE POUR TURBINES
Abstract:
(EN) This application provides controlled tip balance slits (200) for turbines. An example leakage flow control system (110) for a turbine may include a flow runner (150) with a tip shroud (152), a diaphragm or a guide blade (130), an extension ring (160) coupled to the diaphragm and positioned adjacent to the tip shroud (152), and a tip balance slit (200).
(FR) Cette application fournit des fentes d'équilibrage de pointe commandées (200) pour des turbines. Un exemple de système de commande d'écoulement de fuite pour une turbine peut comprendre un canal d'écoulement (150) avec un carénage de pointe (152), un diaphragme ou une aube fixe (130), une bague d'extension (160) couplée au diaphragme et positionnée de façon adjacente au carénage de pointe (152), et une fente d'équilibrage de pointe (200).
