Maintenance and upkeep of high-temperature fans should be combined with the equipment's operating characteristics and industry standards. The following is a systematic maintenance strategy:
Daily Inspection and Basic Maintenance
1. Electrical System Testing
Manually test the start/stop function and observe whether the voltage/ammeter in the control cabinet is normal.
Check the motor insulation performance and grounding reliability to prevent leakage risks.
Regularly clean dust from electrical components to avoid short circuits or poor contact.
2. Mechanical Component Maintenance
Add the specified type of lubricating oil (high-speed machine oil) to the bearings every 1000 hours.
Check the coaxiality of the coupling and adjust the impeller-casing clearance to prevent friction and vibration. Tighten bolts, locating pins, and other connecting parts to eliminate potential loosening hazards.
Special Maintenance of Key Components 1. Bearing and Vibration Control: Monitor bearing temperature rise (normal ≤95℃), check lubrication or replace if abnormal. Perform dynamic balancing calibration regularly to resolve vibration problems caused by impeller deformation.
2. Cooling System Optimization: Clean dust from heat sinks to ensure ventilation efficiency (especially in high-temperature seasons). Check coolant level and pipe sealing to prevent leaks leading to overheating.
Periodic Deep Maintenance:
1. Replacement of Wear Parts: Replace gaskets, belts, and other consumables every 1000-1200 hours of operation. Check the intake filter; clean with a neutral detergent if heavily soiled.
2. Performance Testing: Record operating parameters (pressure/flow/temperature), compare with historical data to predict faults. Check impeller wear during shutdown, repair or replace if necessary.
Environment and Operation Management:
1. Installation Environment Requirements: Ensure good ventilation in the machine room; avoid hot air backflow at the air inlet/outlet. Install heat insulation materials in high-temperature areas to reduce the impact of ambient temperature.
2. Personnel Training: Operators must master emergency shutdown procedures and preliminary fault diagnosis methods. Maintenance files must be established, recording the content of each maintenance session and handling of any abnormalities.
Note: Maintenance cycles need to be adjusted according to actual operating conditions. Maintenance intervals should be shortened in dusty or continuous operation scenarios.
