Steam turbine, and intermediate support structure for holding row of long moving blades therein |
摘要 |
A row of moving blades for a steam turbine has moving blades elongated radially which are arranged peripherally around and secured to a turbine rotor. The row also has an intermediate support structure for holding the blades to each other at a radially intermediate position. The support structure has a shape of a streamline cross section. The support structure may include a tie wire secured to the blades, or lugs protruding from the blades and combined to each other. The support structure may include lugs protruding from the blades to each other, and a sleeve combining the lugs. The shape of a streamline cross section may have an obtuse-angle or acute-angle upstream part. |
