A detailed Deaerator QUARTERLY preventive maintenance checklists
1. Visual Inspection
2. Operational Checks
3. Mechanical Components
- Inspect pump casing for cracks or corrosion.
- Look for wet spots or pooling around the base.
- Listen for unusual noises during operation.
- Check seals and gaskets for integrity.
- Ensure proper alignment with the motor.
- Manually operate each valve to check responsiveness.
- Look for leaks around valve stems and connections.
- Check for corrosion or build-up on valve body.
- Ensure valve handles are secure and operational.
- Verify that valve positions are correctly indicated.
- Use recommended lubricant type and amount.
- Clean surfaces before application to avoid contamination.
- Rotate bearings while applying lubricant for even distribution.
- Check for excess lubricant and wipe away.
- Follow the manufacturer's interval recommendations.
- Inspect trays for structural integrity and corrosion.
- Check for proper fit within the vessel.
- Look for signs of scaling or fouling.
- Ensure there are no obstructions on the trays.
- Confirm uniform spacing between trays.
- Look for rust or pitting on the external shell.
- Check for bulging or deformation in the shell.
- Inspect welds for cracks or separation.
- Ensure proper drainage to prevent water accumulation.
- Use a thickness gauge to measure metal integrity.
- Visual inspection for wet spots at connections.
- Tighten any loose fittings as needed.
- Check for signs of rust or corrosion.
- Use leak detection fluid to identify small leaks.
- Inspect gaskets and seals for wear or damage.
- Manually test the pressure relief valve operation.
- Check for signs of corrosion or damage on valves.
- Ensure discharge piping is clear and unobstructed.
- Verify calibration against pressure specifications.
- Inspect valve springs for proper tension.
- Check for signs of hot spots or discoloration.
- Inspect insulation for damage or wear.
- Look for leaks at joints and connections.
- Ensure proper drainage to prevent water accumulation.
- Use a thermal camera to detect heat loss.
- Inspect for cracks or fogging in the sight glass.
- Use appropriate cleaning solution to remove buildup.
- Ensure sight glass is properly sealed and secured.
- Check for condensation or leaks around fittings.
- Replace if visibility remains compromised.
- Simulate low and high water levels to test response.
- Check calibration against actual water levels.
- Inspect wiring and connections for integrity.
- Test alarms for proper functionality.
