摘要： An arrangement is disclosed in which deflections and mechanical stresses in turbine low pressure casings are controlled by inserting struts between the turbine diaphragm ledge ring stages. Preferably, the struts are cylindrical in shape, although other different shapes can be used in accordance with the needs of different applications. The struts can be solid or hollow in construction, although preferably they are hollow to reduce the material needed to fabricate them. The struts are located around the turbine casing, as is required to connect together two ledge rings where there is high axial deflection in the casing.
摘要翻译： 公开了一种布置，其中涡轮机低压壳体中的偏转和机械应力通过在涡轮隔膜凸缘环级之间插入支柱来控制。 优选地，支柱的形状为圆柱形，尽管可以根据不同应用的需要使用其他不同的形状。 支柱可以是实心的或中空的结构，尽管优选地它们是中空的，以减少制造它们所需的材料。 支柱位于涡轮机壳体周围，因为将壳体中存在高轴向偏转的两个凸缘环连接在一起是必需的。
