False vibration indications?
Unexpected outage delays?
Standard preventative maintenance procedures for generators, turbines, compressors and pumps can be greatly enhanced by demagnetizing services. And in some unplanned outages, magnetism is a root cause.
Magnetized rotors can generate stray currents
Magnetized rotors can generate stray currents which discharge across the close tolerances found between the rotor and diaphragms or bearings.
The electrical discharge can result in decreased efficiency, premature wear and vibration issues that can cause unplanned outages and possible damage to the equipment train.
Magnetized rotors can attract small metal filings
Any time the casing is opened, especially during an outage, small metal filings can be drawn to the magnetized areas. They then become lodged in the equipment and in the lubricating oil system resulting in damage if not found early enough.
Magnetized turbine and compressor casings can cause Problems during balancing and alignment
When aligning using a taught line and a micrometer, magnetism can cause false readings which can result in bearing rubs, misalignment, and extended outages.
Magnetized rotors can exhibit false vibration indications
Proximity monitor alarms can be triggered erroneously if the rotors are magnetized. These false indications can result in an unnecessary shutdown of the equipment if the alarm is not repeatedly overridden.
