Using vibration analysis on rotating machinery,
enables the early detection of faults before breakdown. This will
reduce economical losses to production and equipment, saving industry
millions of dollars in machine down time.
The evaluation of the changes in vibration response,
critical speeds and stability of a machine, has become an important
part of most maintenance programs. The aim
therefore, is to evaluate machine condition for weaknesses. This
will enable the diagnosis of faults, therefore repairs can be planned
and performed economically.
The list below indicates typical problems
that could affect rotating machinery:
- Unbalance
- Misalignment
- Eccentricity
- Bent shaft
- Shaft crack
- Mechanical looseness
- Journal bearing faults
- Rolling element bearing faults
- Rotor rub
- Cavitation
- Electrical motor problems
- Gear faults
Vibration assessments are also necessary to
indicate possible damage to buildings and the effects on its occupants.
- Vibration on building structures
- Impact assessment
- Vibration on people and sensitive equipment
- Environmental noise related to vibration
