- Misalignment
- Bearing damage
- Lubrication failure
- Looseness
- Seal failure
- Gear wear
- Cavitation
- Overheating
- Excessive vibration
Practical example
A pump is monitored using vibration, bearing temperature, seal leakage, lubricant condition, and operating pressure.
Maintenance methods
Controls may include alignment, lubrication, balancing, condition monitoring, inspection, and performance testing.
Common mistake
Maintaining only the driver or driven unit without considering the complete train, foundation, coupling, piping, and operating conditions can leave the real cause unresolved.
