Compressor equipment operates under high load, and its engines are especially susceptible to overheating. Let's tell a case of how Elektromotors engineers restored a compressor motor in Tashkent.
Situation
At a production facility in Tashkent, a screw compressor motor overheated and stopped. The compressor provided compressed air to the entire line, so its downtime stopped production.
Diagnostics
Diagnostics revealed a set of problems:
- Overheating and partial destruction of the winding insulation.
- Dust-clogged cooling system.
- Worn bearings, giving additional heating.
Repair
- Rewinding of the winding with class H insulation (increased heat resistance).
- Replacement of bearings.
- Cleaning and restoration of the cooling system.
- Balancing of the rotor and testing under pressure load.
Result
| Indicator | Result |
|---|---|
| Insulation | Class H (increased) |
| Cooling | Restored |
| Warranty | 12 months |
The engine was returned to operation with an increased heating margin. The customer was recommended to regularly clean the cooling system - it was its contamination that became the root cause of overheating. Prevention is cheaper than repair.
