Kumaran Industries Best Tips for Preventive Maintenance of Centrifugal Fans Centrifugal fans are vital components in many industrial processes, ensuring airflow, cooling, exhaust, and ventilation. Whet her in manufacturing plants, power stations, chemical facilities, or refineries, regular preventive maintenance helps avoid costly downtime and extends the lifespan of your equipment. In this post, here are the best tips to keep your centrifugal fans running smoothly. 1. Regular Cleaning of Blades an d Housing Dust, dirt, and debris gradually build up on fan blades, the inlet and outlet, and inside the housing. This buildup causes im balance, reduces airflow, increases vibration, and forces the motor to work harder. Clean the impeller blades and housing at scheduled intervals , monthly or quarterly , depending on how dusty the environment is. A clean fan performs more efficiently. 2. Bearing Lubrication and Inspection Bearings are among the most critical parts. Lack of lubrication or dirty bearings lead to overheating, noise, and eventual failure. Follow the manufacturer’s guidelines for the type of lubricant, how often to apply it, and how much. Also inspect for signs of wear, moi sture entry, or misalignment. 3. Monitor Vibration, Motor, and Alignment Bala nced components reduce strain. If the impeller is out of balance, or if shafts are misaligned, vibration increases, reducing the useful life of both fan and motor. Keep an eye (or sensor) on vibration levels. Also check electrical connections, motor windin g temperatures, insulation, and ensure everything is aligned properly. 4. Inspect Drive Mechanisms (Belts/Couplings/Pulleys) If your centrifugal fan uses belts or pulley drives, check belt tension and condition. Worn or misaligned belts cause slippag e, red uce performance, and can damage other parts. If direct - drive or coupling - based, ensure coupling alignment and condition. Replace any comp onent that shows signs of wear. 5. Fastener Tightness & Structural Integrity With vibration and regular operation, bolt s, nuts, mounts, and housings can loosen. These loose components can lead to misalignment, excessive vibration, and even safety risks. Establish a schedule to check fasteners, inspect the housing for corrosion or cra cks, and ensure the structural frames ar e robust 6. Temperature, Seal, and Environment Checks Fans operating in high - temperature or corrosive environments need extra care. Make sure seals are intact to prevent ingress of dust or moisture. Monitor temperatures of bearings and motors, especially under load. In humid or corrosive atmospheres, protective coatings might be required. Also, ensure that fan shutdowns occur only when safe (e.g., not shutting off abruptly under hot conditions). 7. Maintain Records and Scheduled Preventive Maintenance Plans A maintenance plan is only as good as its documentation. Keep logs of inspection dates, lubrication, parts replacements, vibr ation or temperature readings. This helps spot trends, anticipate failures, and plan downtime for maintenance rat her than dealing with emergencies. Why Working With The Right Manufacturer Helps ?
