Generators, like other equipment, are not engineered to last forever. While preventive maintenance prolongs the manufacturer’s stated “expiry” date, it is not a magic bullet. Sooner or later, it becomes essential to consider the option of a generator rotor removal. Although a period of shut-down is necessary to accomplish this, it often remains the only means through which to ensure ongoing productivity and prevent ultimate and more costly mechanical and/or electrical failure.
Factors Surrounding Removal
Rotors are moving parts. They do not act alone but interact with other components of the generator. Problems occur as a result of various issues, including imbalance, damaged damper, overheating, and vibrations. When pondering a rotor removal, it is important to consider various factors, including:
- Problem: What is the reason? Will replacing the rotor be a permanent fix or do other components require repair or replacement?
- Speed: It is very important to ensure downtime is minimal.
- Safety: The safety of all involved is crucial during the entire process
- Technology: It is important to utilize the best possible technology. Off-site monitoring can detect the issues and indicate repair of the unit and or its components, or the need to perform the ultimate action – generator rotor removal
- Experience and Skill: Only those who are highly skilled and trained in removal should be in positions where their expertise in this area is essential
Always look at the various factors involved, including the location of the generator and whether on or off-site removal is the most feasible, effective, and efficient means of removing the affected generator rotor.
Generator Rotor Removal
Some problems affecting the optimal operation of a generator may not relate to the rotor. Other issues may prove to be minor and require basic repairs or replacement of certain parts. However, as the generator ages, it may require more drastic measures to ensure ongoing productivity. One process the equipment may undergo to ensure this is a generator rotor removal.
