What is the purpose of notches in steam turbine blades?
Thread Content
GE steam turbine, condensing type, more than 5,000 units installed. I found a gap on the new rotor impeller. What is the purpose of this design? By the way, can you send me some photos of the steam turbine and compressor that were overhauled this time?
This is called a riveted integral girdle. Since the blades are shorter, have better stiffness and lower natural vibration frequency, riveted shrouds can be used. The gap here is the blade installation locking port.
The turbine blades have a shroud structure, and the notch is for locking!
