摘要:
A sealing cover (20) used for a gas turbine (100). The gas turbine (100) comprises at least one turbine disk (143), and the sealing cover (20) is used to cover the turbine disk (143). A side wall (22a) of the sealing cover (20) is provided with a first air hole (222) and a second air hole (223). A spacing is formed between the first air hole (222) and the second air hole (223). A cooling passage (226) and a plurality of ribs (225) are provided within the sealing cover (20). The cooling passage (226) is in communication with the first air hole (222) and the second air hole (223), and the plurality of ribs (225) are disposed within the cooling passage (226) or outside the cooling passage (226). In addition, the plurality of ribs (225) are formed within a weight reduction cavity. A gas turbine (100) and a manufacturing method of a sealing cover (20) are also provided. The sealing cover (20) helps to improve working performance of the gas turbine (100).
摘要(中):
用于燃气轮机(100)的密封盖(20)。 燃气涡轮机(100)包括至少一个涡轮盘(143),并且密封盖(20)用于覆盖涡轮盘(143)。 密封盖(20)的侧壁(22a)设有第一气孔(222)和第二气孔(223)。 在第一气孔(222)和第二气孔(223)之间形成间隔。 冷却通道(226)和多个肋(225)设置在密封盖(20)内。 冷却通路226与第一空气孔222及第二空气孔223连通,多个肋225配置在冷却通路226内或冷却通路226的外部 )。 另外,多个肋(225)形成在减重腔内。 还提供了燃气轮机(100)和密封盖(20)的制造方法。 密封盖(20)有助于提高燃气轮机(100)的工作性能。 p>
