How does GE repair a steam turbine?
GE has developed an array of proven repair techniques for all parts of the industrial steam turbine. Rotor repairs, straightening, balancing, weld repairs, disc head repairs, disassembly, and rebuild The repairs are usually executed in our specialized repair workshops or even on-site with our mobile repair equipment.
Do generator rotor fan vanes & blower blades fail?
The potential failure of generator rotor fan vanes and blower blades has been identified as an area for detailed risk assessment in the electric power generation industry. Liberation of fan component has caused catastrophic damage to both the rotor and stator components on a number of units.
Why do generator fan wheels fail?
Similar to retaining rings, these surfaces are subject to larger interference fits which should periodically be inspected. The failure mechanisms most common to generator fan wheels include: low cycle fatigue, high cycle fatigue, brittle fracture, corrosion and erosion.
Which filler metal is used to repair cracks in a pump turbine?
Cracks in the casing of a pump turbine made of DIN 14315 standard cast material number 1 0553 was also successfully repaired (Geissler 1992) using build-up welding under inductive preheating at 423K using E515 B11020 (H) electrodes. This filler metal was selected on the basis of its good toughness values.
