圆盘式转子支架由于具有结构紧凑,刚度大和通风良好等优点,已被国际上众多的发电机制造厂所采用,尤其是将该结构用于中大型水轮发电机,岩滩转子支架是由中心体和10个扇形外环组件组成,系圆盘结构。其外径14.4m 高2.75m,总重达193t。该支架的制造特点是厂内制成分半件,在工地装焊成整体。采用的新工艺如下:(1)以精密火焰切割取代机械加工。转子支架扇形外环组件间连接处的径向缝,及外环组件与中心体连接处环缝和立缝按传统工艺需
Due to its advantages of compact structure, large rigidity and good ventilation, the disc rotor support has been adopted by many generator manufacturers in the world. In particular, this structure is used in medium and large hydroelectric generators. Central body and 10 sector-shaped outer ring components, Department of disc structure. Its outer diameter 14.4m high 2.75m, the total weight of 193t. The manufacture of the stent is made of the factory features half, installed in the workplace into the overall welding. The new technology used are as follows: (1) to replace the precision flame cutting machining. Rotor bracket fan-shaped outer ring joints between the radial joints, and the outer ring assembly and the central body at the junction of girth and vertical sewing required by the traditional process
