    • PURPOSE: A cooling system for cooling a rotor is provided to use a space useful for the cooling system economically while flowing a cooling medium into buckets with uniform distribution. CONSTITUTION: In a turbine rotor(10) having axially spaced wheels(14,16,18,20) mounting buckets(22,24,26,28) and spacers(30,32,34) between the wheels, a cooling system for cooling the buckets comprises plural manifold segments circumferentially spaced from one another about and adjacent the rim of the rotor, and a retention system supported by the manifold segments and cooperable with the spacer for securing the manifold segments to the spacer against substantial axial movement relative to the rotor. Each manifold segment lies in communication with at least one passage(58) for flowing a cooling medium to or from the manifold segment. Each manifold segment has plural ports in communication with flow passageways of turbine buckets of at least one of the turbine wheels. The retention system includes a rib and a recess and another of the rib and the recess on each the manifold segment. The rib is engageable in the recess to retain the manifold segment on the spacer against substantial axial movement.
    • 目的:提供一种用于冷却转子的冷却系统,以便在将冷却介质流动到具有均匀分布的水桶中时,经济地使用用于冷却系统的空间。 构造:在具有在轮之间安装铲斗(22,24,26,28)和间隔件(30,32,34)的轴向间隔开的轮(14,16,18,20)的涡轮转子(10)中, 冷却桶包括多个歧管段,其围绕并邻近转子的边缘彼此周向间隔开,并且保持系统由歧管段支撑并与间隔件配合,用于将歧管段固定到间隔件上,以相对于 转子。 每个歧管段与至少一个通道(58)连通,用于将冷却介质流向歧管段或从歧管段流出。 每个歧管段具有与至少一个涡轮机轮的涡轮机叶片的流动通道连通的多个端口。 保持系统包括肋和凹部以及每个歧管段上的另一个肋和凹部。 所述肋可接合在所述凹部中,以将所述歧管段保持在所述间隔件上以防止实质上的轴向运动。

    • PURPOSE: A multi-stage turbine and a method for purging front and rear wheel spaces are provided to improve the efficiency of a gas turbine. CONSTITUTION: In a multi-stage turbine, at least one turbine wheel(12) supports a row of buckets(14) for rotation, and the turbine wheel is located axially between first and second annular fixed arrays of nozzles(36, 38). A cooling air circuit for purging a wheel space between the turbine wheel and the second fixed annular array of nozzles(38) comprises a flow path through a shank portion(50) of one or more buckets connecting a wheel space between the turbine wheel and the first fixed annular array of nozzles(36) with the wheel space between the turbine wheel and the second fixed annular array of nozzles. The shank portion of the one or more buckets includes a forward wall and a rear wall forming, in part, a hollow chamber in the shank portion. The flow path is formed by at least one hole in the forward wall, the hollow chamber, and at least one hole in the rear wall.
    • 目的:提供一种多级涡轮机和一种用于清洗前轮和后轮空间的方法,以提高燃气轮机的效率。 构造:在多级涡轮机中,至少一个涡轮机叶轮(12)支撑一排用于旋转的铲斗(14),并且涡轮机叶轮位于第一和第二环形固定喷嘴阵列(36,38)之间。 用于清洗涡轮机叶轮和第二固定环形喷嘴组(38)之间的车轮空间的冷却空气回路包括通过一个或多个铲斗的柄部(50)的流动路径,其连接涡轮机叶轮和 喷嘴(36)的第一固定环形阵列,其中所述涡轮机叶轮和所述第二固定环形阵列喷嘴之间的轮空间。 一个或多个铲斗的柄部分包括前部壁和后壁,该后壁部分地形成柄部分中的中空腔。 流路由前壁,中空室和后壁中的至少一个孔中的至少一个孔形成。
