Operating Instructions
Installation Guidelines
Place the motor or equipment on a stable, vibration-free foundation.
Ensure proper alignment of the shaft and connected equipment.
Connect electrical wiring according to local explosion-proof regulations.
Verify grounding to prevent static buildup.
Install necessary monitoring and safety devices such as thermal sensors or pressure gauges.
Start-Up Procedure
Check that all safety covers and enclosures are secure.
Open any inlet valves and ensure priming of pumps or equipment if required.
Start the motor gradually and monitor current, voltage, and vibration levels.
Confirm stable operation before full-load operation.
Routine Operation
Maintain fluid quality in pumps or pipelines to prevent wear and corrosion.
Avoid frequent starts and stops to reduce mechanical stress.
Monitor temperature, noise, and vibration to detect early faults.
Shutdown Procedure
Close discharge valves or fluid supply gradually to avoid hydraulic shock.
Turn off the motor and allow the equipment to cool down.
Inspect for any leakage, wear, or abnormal noise before next operation.
Fault Cause Analysis
| Fault | Possible Cause | Recommended Action |
|---|
| Motor fails to start | Power supply issue, fuse blown, wiring fault | Check voltage, inspect wiring, reset protection devices |
| Overheating | Overload, blocked airflow, bearing failure | Reduce load, clean ventilation, replace bearings |
| Excessive vibration | Misalignment, unbalanced rotor, loose foundation | Realign shaft, balance rotor, tighten mounting bolts |
| Leakage | Worn mechanical seal, gasket failure | Replace seals or gaskets, inspect mating surfaces |
| Low efficiency | Cavitation, corrosion, or scaling | Clean internal components, check fluid quality, monitor operating conditions |
Tips: Regular inspection and monitoring can prevent most operational faults and extend service life.
