A detailed Cooling Tower QUARTERLY preventive maintenance checklists
1. Visual Inspection
2. Mechanical Components
3. Water System Inspection
- Collect water samples from various points.
- Use calibrated meters for pH and conductivity.
- Test hardness using appropriate chemical test kits.
- Record results and compare with acceptable ranges.
- Adjust treatment as needed based on findings.
- Shut down the system and isolate strainers/filters.
- Remove strainers and filters from their housings.
- Clean with water or appropriate cleaning solution.
- Inspect for damage or wear; replace if necessary.
- Reinstall and ensure they are securely fastened.
- Examine piping and joints for leaks or corrosion.
- Check spray nozzles for clogs or blockages.
- Look for signs of water pooling or dampness.
- Use a flashlight for better visibility in dark areas.
- Document any issues and schedule repairs.
- Check make-up water valve for proper operation.
- Inspect supply line for leaks or blockages.
- Monitor flow rate to ensure adequate supply.
- Ensure sensor activation is functioning correctly.
- Document findings and address any irregularities.
- Check chemical levels in storage tanks.
- Inspect feed lines for clogs or leaks.
- Verify calibration of chemical dosing pumps.
- Ensure safety equipment is in place and functional.
- Record chemical usage and adjust dosing if needed.
- Test float operation by manually adjusting water levels.
- Clean sensors to remove any buildup or debris.
- Check wiring connections for signs of wear.
- Ensure sensors respond accurately to water level changes.
- Document any faults and schedule repairs.
- Inspect visible piping for corrosion signs.
- Check for scale buildup in fittings and valves.
- Use a wire brush for light cleaning as needed.
- Note any areas requiring further inspection.
- Schedule maintenance for heavily corroded sections.
- Review dosing logs for consistency and accuracy.
- Check calibration of chemical dosing equipment.
- Inspect chemical injection points for leaks.
- Test water samples for residual chemical levels.
- Adjust dosing as necessary based on test results.
- Remove any floating debris from the basin surface.
- Check for sediment accumulation at the bottom.
- Use a vacuum or net for effective cleaning.
- Inspect basin walls for algae or biofilm growth.
- Document cleaning activities for maintenance records.
- Place thermometers at key points in the system.
- Record temperatures at regular intervals.
- Compare readings to operational benchmarks.
- Look for temperature fluctuations that may indicate issues.
- Document findings for future reference.
- Inspect overflow pipes for blockages or damage.
- Test overflow operation by simulating high-water conditions.
- Ensure proper drainage away from the cooling tower.
- Clean any debris from overflow openings.
- Document any issues and schedule necessary repairs.
- Remove any visible debris from the sump area.
- Check for sediment buildup that may affect drainage.
- Use a sump pump or vacuum for thorough cleaning.
- Inspect sump pump operation and test functionality.
- Record cleaning activities in maintenance logs.
- Check labels on pipes, valves, and equipment.
- Ensure labels are clear, legible, and durable.
- Replace any missing or damaged labels.
- Verify that labels comply with safety standards.
- Document labeling status for future audits.
- Gather operation logs from the past quarter.
- Look for patterns in water usage and quality.
- Identify any anomalies or unexpected fluctuations.
- Discuss findings with the maintenance team.
- Plan corrective actions based on trends observed.
- Visually inspect water surface for discoloration.
- Test water samples for microbial growth if needed.
- Use a net to remove floating debris and algae.
