，及時(shí)補(bǔ)充潤滑油，為保障良好的潤滑效果，推薦使用 ISO VG 220 齒輪油；對水冷型風(fēng)機(jī)的冷卻器進(jìn)行全面清理，仔細(xì)檢查整個冷卻水系統(tǒng)，確保冷卻水流量達(dá)到或超過 2m3/h，以維持良好的散熱性能；通過合理調(diào)整工況，加裝安全閥或采用變頻控制等技術(shù)手段，避免風(fēng)機(jī)超壓運(yùn)行，確保其在安全、高效的工作區(qū)間內(nèi)運(yùn)轉(zhuǎn)；當(dāng)軸承出現(xiàn)損壞時(shí)，及時(shí)更換耐高溫、性能優(yōu)良的軸承，建議選用 SKF、NSK 等知名品牌產(chǎn)品，以提升風(fēng)機(jī)運(yùn)行的穩(wěn)定性和可靠性。

The overheating of the fan, that is, the high temperature of the bearings or housing, is mainly caused by multiple key links. Insufficient or deteriorated lubricating oil is an important cause. If the oil level is too low to provide sufficient lubrication, the lubrication performance of the oil will significantly decrease after aging, which will lead to increased friction between components and generate a large amount of heat; For water-cooled fans, cooling system failure is the direct cause of overheating. Insufficient cooling water flow or pipeline blockage prevents timely removal of heat generated during operation, resulting in continuous temperature rise; Overload operation cannot be ignored either. When the system resistance is too high or the exhaust pressure exceeds the rated working pressure of the fan, the fan will be in an overloaded state for a long time, which will inevitably generate excessive heat; Bearing damage is also a common factor, as poor lubrication or long-term fatigue wear can lead to bearing jamming, exacerbating friction and ultimately causing overheating. Effective solutions to these issues include regularly checking the oil level and replenishing lubricating oil in a timely manner. To ensure good lubrication, it is recommended to use ISO VG 220 gear oil; Thoroughly clean the cooler of the water-cooled fan, carefully inspect the entire cooling water system, and ensure that the cooling water flow rate reaches or exceeds 2m 3/h to maintain good heat dissipation performance; By adjusting the working conditions reasonably, installing safety valves or using frequency conversion control and other technical means, the fan can avoid overpressure operation and ensure its safe and efficient operation within the working range; When the bearing is damaged, it is recommended to replace it with a high-temperature resistant and high-performance bearing in a timely manner. It is suggested to choose well-known brands such as SKF and NSK to improve the stability and reliability of the fan operation.
