Description
The control wheel is located behind the set of nozzles, which is the inner part of the rotor, commonly called the rotor chest; The rotor blades along with the base and the cover (shroud) are produced by one-handed machining and a piece of solid metal material.
The control wheel vanes are loaded very dynamically, especially in the partial receiving area. A rolled wire acts as a damping element for possible vibrations. The rest of the rotor pressure vanes are equipped with an integrated shroud. The last two stages of condensing turbines are standardized and leveled as free twisted blades without a cover strip, which are connected to each other by a so-called damping wire. The roots of the blade are produced in different shapes of finger, hammer, or firewood, depending on the specific loading situation. All blades are made of 13% chrome steel. The guide blades are attached to the guide blade.
Each row is equipped with an integrated or riveted cover strip.
