As the "cooling core" in industries such as petrochemicals and electric power, the operating status of air coolers directly affects production efficiency and energy consumption. Scientific maintenance management not only extends equipment service life but also reduces the risk of breakdown and shutdown. The following practical maintenance guide helps you precisely safeguard equipment performance.
1. Daily Inspection: Building the "First Line of Defense" for Operation
Daily inspections should focus on three core aspects: first, appearance check-inspect whether fins are deformed and frames are corroded, and promptly clean up blockages such as debris and fallen leaves accumulated on the surface; second, operating parameter monitoring-track inlet and outlet temperature, pressure, and fan speed through the instrument panel, and immediately investigate if the deviation exceeds ±5%; third, inspection of dynamic and static components-confirm that fan blades are not loose, motors operate without abnormal noise, and the belt tightness should be appropriate when pressing down 10-15mm.
2.Regular In-depth Maintenance: Extending Equipment "Service Life"
In-depth maintenance should be carried out quarterly: for fin scaling, use high-pressure water jet (pressure ≤15MPa) for cleaning; if oil contamination is severe, use neutral cleaning agents to avoid material corrosion; check the tightness of tube bundles, detect leak points through pressure tests, and promptly apply anti-corrosion coating to slightly corroded parts; replace the lubricating oil for fan bearings, select the appropriate type (e.g., 3# lithium-based grease), and the filling amount should be 2/3 of the bearing cavity.
3. Fault Early Warning: Responding Quickly to "Abnormal Signals"
When a sudden drop in heat exchange efficiency occurs, it is mostly due to fin blockage or scaling, requiring immediate shutdown for cleaning; if there is abnormal fan vibration, check the balance of blades and the tightness of fixing bolts; in case of motor overheating, inspect voltage stability and whether the heat dissipation channel is unobstructed. In case of sudden faults, prioritize starting the standby cooling system to avoid affecting the production process.
Professional maintenance can increase air cooler energy efficiency by over 20% and extend equipment service life by 3-5 years. For customized maintenance plans, you can contact our technical team for one-on-one support to ensure continuous and stable operation of the equipment.
