The reasons for high bearing temperature in a pipeline pump

The reasons for high bearing temperature in a pipeline pump can be as follows

1. Damaged bearings: Frequent cause, like broken retainers or worn balls in rolling bearings, or delamination in sliding bearings.

2. Shaft misalignment or deviation: Leads to vibration and heat.

3. Increased axial thrust: Causes extra load and heating.

4. Lubrication issues: Insufficient, excessive, or contaminated oil, resulting in overheating.

5. Incorrect clearances: Between bearing parts contribute to overheating.

6. Poor rotor balance: Unbalance leads to additional radial force and heat.

7. Non-designed operating conditions: Vibration from improper operation increases bearing temperature.
