What Is Rotating Equipment?
Rotating equipment includes any machine with moving/rotating components, such as:
-
Centrifugal pumps
-
Gear pumps
-
Fans & blowers
-
Compressors
-
Motors & generators
-
Turbines
-
Gearboxes
-
Stirrers & mixers

Different Ways to Take Care of Rotating Equipment:
1. Maintenance to avoid problems:
Inspections on a set schedule to avoid problems.- Putting on oil
- Checks on bearings
- Checking the coupling
- Checks the belt tension
- Keeping strainers and screens clean
2. Condition-based maintenance (CBM) or predictive maintenance:
uses tools to find problems before they happen.- Checking for vibrations
- A thermogram
- Ultrasound to find leaks
- Analysis of motor current signature
3. Maintenance to fix problems:
After finding a failure, fix or repair the parts.

- Not balanced
- Wear on bearings
- Loose nuts
- Problems with soft feet
Fix:
- Balance the wheel again.
- Use a precise tool for alignment
- Lock down the base bolts.
- Change out old bearings

2. Getting too hot:
Reasons:
- Not enough grease
- Motor overload
- Filters are blocked
- Failure of bearings
Fix:
- Use the right grease or oil.
- Lower the load
- Keep cooling systems clean.
- Change the springs
3. Noise from the bearing or failure:
Reasons:
- Not enough grease
- Not straight
- Getting dirty
- Lots of vibrations

Fix:
- Make sure you use good grease.
- Keep the line
- Replace the bearings before they completely fail.
4. Out of place:
Reasons:
- Installing something wrong
- Setting of the foundation
- The growth of heat
- Loose nuts
Fix:
- Straighten out the laser
- Fix a soft foot
- Fix the nuts.
- Change the shims
5. Seal Leaks:
Reasons:

- Seals that are worn out
- Not enough pressure
- Hollowing out
- Rotor not balanced
Fix:
- Change to the right type of seal
- Keep the pump's pressure levels steady.
- Do not run when it is dry.
Rotating Equipment Maintenance Kit You Need:
1. Vibration analyzer for computers:
- Find problems early and stop unexpected shutdowns from happening.
2. Tool for Aligning the Laser:
- Get accurate positioning in just a few minutes.
3. A camera for thermal imaging:
- Find motors, couplings, and gears that are getting too hot.
4. Use a multimeter to check the electricity:
- It's useful for checking out cars.

5. Full set of mechanic's tools:
- Important for all kinds of upkeep.
How to Make Things Reliable for a Long Time:
To get the most out of your tools, do these things:- Keep records of repair
- Teach technicians how to do vibration measurement and alignment.
- Check the bearing temperature once a week.
- OEM parts should be used.
- Be sure to lubricate at the right times.
- Do job reviews every year.
