Commissioning Plan of an Agitator
1. Pre-Commissioning Checks
- Documentation Review
- Review P&ID, datasheets, vendor manuals, and installation drawings.
- Visual Inspection
- Check for physical damage during transport or installation.
- Ensure correct alignment and positioning of the agitator.
- Mechanical Checks
- Verify tightness of bolts and mounting hardware.
- Check shaft alignment and coupling.
- Ensure seals and bearings are installed correctly.
- Electrical Checks
- Confirm motor wiring per vendor specs.
- Check insulation resistance of motor windings.
- Verify correct motor rotation (bump test).
- Lubrication
- Fill gearboxes and bearings with specified lubricants.
2. Installation Verification
- Confirm tank and agitator are level.
- Ensure impeller clearance and orientation are correct.
- Verify that all instrumentation (e.g., vibration sensor, temperature probe) is installed and connected.
3. Dry Run Test (No Load)
- Run the agitator without fluid for a short duration.
- Check for:
- Unusual noise or vibration.
- Proper motor rotation.
- Bearing and seal temperature rise.
- Smooth startup and shutdown.
Commissioning Plan of an Agitator
4. Wet Commissioning (With Process Fluid)
- Slowly fill the tank with process fluid.
- Start the agitator at low speed and gradually ramp up.
- Observe:
- Proper mixing and flow patterns.
- Stable operation under load.
- Seal and bearing performance.
- Vibration levels.
5. Control System Integration
- Verify correct functioning of speed control (VFD, soft starter, etc.).
- Test interlocks, alarms, and emergency stop functionality.
- Confirm that local/remote control switching works.
6. Performance Testing
- Run for a specified period under normal operating conditions.
- Record:
- Power consumption.
- Shaft vibration and bearing temperatures.
- Noise levels.
- Mixing effectiveness (as per process requirements).
7. Handover Documentation
- Final inspection report.
- Test and calibration certificates.
- Operation and maintenance manual.
- As-built drawings.
- Sign-off by mechanical, electrical, and process engineers.
