Transportation Precautions
Proper handling during transportation ensures the longevity and safety of WCB 220V Ex-Proof equipment:
Packaging and Securing
Use sturdy crates or pallets with anti-vibration materials.
Ensure moisture-proof wrapping to prevent corrosion.
Secure motors and components to prevent movement during transit.
Handling
Use lifting equipment such as cranes or forklifts.
Avoid dropping, impacts, or scratches.
Protect the shaft, housing, and terminal box during handling.
Environmental Protection
Avoid exposure to rain, snow, or excessive humidity.
Prevent contact with hazardous chemicals during transportation.
Store temporarily in dry, ventilated areas before installation.
Maintenance Cycles
Routine maintenance ensures safe and efficient operation of WCB 220V Ex-Proof motors and equipment.
| Component | Maintenance Frequency | Key Actions |
|---|
| Bearings | Every 3–6 months | Lubricate with approved oil/grease, check alignment |
| Mechanical seals | Every 6–12 months | Inspect for wear or leakage, replace if necessary |
| Electrical connections | Every 6 months | Check tightness, inspect insulation, verify voltage and current |
| Housing & exterior | Monthly | Clean dust, inspect corrosion, apply protective coating if needed |
| Motor operation | Daily | Monitor temperature, vibration, noise, and load |
| Full inspection | Every 12–18 months | Inspect all components, replace worn parts, verify explosion-proof certification |
Tips: Following the maintenance schedule reduces downtime and prevents premature failure.
Fault Analysis
| Fault | Possible Cause | Solution |
|---|
| Motor fails to start | Power supply issue, blown fuse, incorrect wiring | Verify voltage, inspect wiring, reset protection devices |
| Overheating | Overload, blocked ventilation, bearing failure | Reduce load, clean ventilation, replace bearings |
| Excessive vibration | Misalignment, rotor imbalance, loose foundation | Realign shaft, balance rotor, tighten mounting bolts |
| Leakage | Damaged seal or gasket | Replace seals, inspect mating surfaces |
| Low efficiency | Cavitation, corrosion, or scaling | Clean internal components, monitor operating conditions |
Proactive monitoring of vibration, temperature, and electrical parameters can prevent most operational faults.
Operating Instructions
Installation Guidelines
Place equipment on a rigid, vibration-free foundation.
