　　濟南的夏季高溫潮濕、冬季寒冷干燥，這種氣候特點對通風管道系統的穩定性提出了較高要求。在日常使用中，通風管道可能出現一些小故障，用戶掌握基礎排查與處理方法，既能保障系統持續運行，又能避免小問題演變成大維修。

　　Jinan's climate characteristics of high temperature and humidity in summer and cold and dry in winter place high demands on the stability of ventilation duct systems. In daily use, there may be some minor malfunctions in ventilation ducts. By mastering basic troubleshooting and handling methods, users can ensure the continuous operation of the system and avoid small problems from escalating into major repairs.

　　異常噪音的排查與處理

　　Troubleshooting and Handling of Abnormal Noise

　　通風管道運行時若出現“嗡嗡”共振聲，首先檢查固定支架是否松動。濟南地區因溫差變化大，金屬熱脹冷縮易導致吊桿螺絲移位，只需用扳手緊固即可消除異響。若聽見“嘶嘶”漏氣聲，可用肥皂水涂抹法蘭連接處，氣泡產生位置即為漏風點，此時需關閉系統，對縫隙處加裝密封膠條或重新擰緊螺栓。對于風閥葉片開合產生的“咔嗒”聲，可滴入少量潤滑油保養軸件，但需注意勿使用酸性油脂腐蝕金屬部件。

　　If there is a "buzzing" resonance sound during the operation of the ventilation duct, first check whether the fixed bracket is loose. Due to the large temperature difference in the Jinan area, metal thermal expansion and contraction can easily cause the suspension rod screws to shift. Simply tighten with a wrench to eliminate the abnormal noise. If you hear a hissing sound of air leakage, you can apply soapy water to the flange connection. The location where bubbles are generated is the air leakage point. At this time, the system needs to be shut down, and sealing strips should be added to the gaps or bolts should be tightened again. For the "click" sound generated by the opening and closing of the air valve blades, a small amount of lubricating oil can be dripped to maintain the shaft components, but care should be taken not to use acidic grease to corrode metal parts.

　　風量衰減的應急處理

　　Emergency response to air volume attenuation

　　當發現送風/排風效果明顯減弱時，先檢查過濾網是否積塵。濟南春季的楊柳絮、冬季的霧霾顆粒易堵塞濾網，用軟毛刷清理后恢復通風量。若風管彎頭處風速降低，可能是內部積灰導致，可拆卸檢修口用吸塵器清理，注意勿損傷鍍鋅層。對于軟連接帆布破損造成的漏風，可用鋁箔膠帶臨時修補，后續再更換標準配件。

　　When the air supply/exhaust effect is significantly reduced, first check whether the filter screen has accumulated dust. The willow catkins in spring and haze particles in winter in Jinan are prone to clogging the filter screen. After cleaning with a soft bristled brush, restore ventilation. If the wind speed at the bend of the air duct decreases, it may be caused by internal dust accumulation. The removable inspection port can be cleaned with a vacuum cleaner, and care should be taken not to damage the galvanized layer. For air leakage caused by damage to the soft connection canvas, aluminum foil tape can be used for temporary repair, and standard accessories can be replaced later.

　　冷凝水問題的季節性應對

　　Seasonal response to condensate water issues

　　在濟南的梅雨季節，通風管道內外溫差大易產生冷凝水。發現保溫層破損時，可用B1級橡塑保溫管對裸露部位進行包裹，接縫處用膠水粘合。若排水不暢導致吊頂滲水，需檢查接水盤是否堵塞，用細鐵絲疏通排水孔，并調整坡度確保冷凝水順暢排出。對于蒸發器結霜現象，可先用吹風機低溫檔融化冰層，再聯系專業人員檢修制冷系統。

　　During the rainy season in Jinan, there is a large temperature difference between the inside and outside of ventilation ducts, which can easily produce condensation water. When the insulation layer is found to be damaged, B1 grade rubber insulation pipes can be used to wrap the exposed parts, and the joints should be glued together. If poor drainage leads to water leakage from the ceiling, it is necessary to check whether the water tray is blocked, use fine wire to clear the drainage hole, and adjust the slope to ensure smooth discharge of condensed water. For the phenomenon of frosting on the evaporator, you can first use a low temperature blower to melt the ice layer, and then contact a professional to inspect the refrigeration system.

　　振動傳遞的消減技巧

　　Techniques for reducing vibration transmission

　　風機運轉產生的振動可能通過風管傳遞至室內，在支架與結構連接處加裝3-5mm橡膠減震墊，可降低70%以上的傳導噪音。對于柔性短管老化開裂問題，可用喉箍固定新軟接臨時替代，但需注意長度不超過200mm，避免影響氣流組織。若發現風管穿墻處振動，可用聚氨酯發泡劑填充縫隙，既密封又減震。

　　The vibration generated by the operation of the fan may be transmitted indoors through the air duct. Installing 3-5mm rubber shock absorbers at the connection between the bracket and the structure can reduce more than 70% of the conducted noise. For the problem of aging and cracking of flexible short tubes, a new flexible joint can be temporarily replaced with a throat clamp, but it should be noted that the length should not exceed 200mm to avoid affecting the airflow organization. If vibration is found at the point where the air duct passes through the wall, polyurethane foam can be used to fill the gap, which is both sealed and shock-absorbing.

　　日常維護要點

　　Key points of daily maintenance

　　建議用戶建立季度巡檢制度：春季重點清理新風入口防蟲網，夏季檢查保溫層完整性，秋季測試風閥啟閉靈活性，冬季確認電伴熱帶工作正常。每次使用后用濕布擦拭風口，避免油污積累。對于商業場所，可加裝壓差開關實時監測風阻，當數值超過初始值30%時啟動預警，及時安排清洗。

　　It is recommended that users establish a quarterly inspection system: focus on cleaning the insect proof net at the fresh air inlet in spring, check the integrity of the insulation layer in summer, test the flexibility of the air valve opening and closing in autumn, and confirm the normal operation of the electric heat tracing belt in winter. Wipe the air vent with a damp cloth after each use to avoid oil accumulation. For commercial premises, a pressure differential switch can be installed to monitor wind resistance in real time. When the value exceeds 30% of the initial value, a warning will be triggered and cleaning will be arranged in a timely manner.

　　掌握這些基礎維護技能，用戶能解決80%以上的通風管道常見問題。對于涉及電路改造、系統調試等專業操作，仍需聯系具備資質的工程人員處理，確保安全運行。

　　By mastering these basic maintenance skills, users can solve over 80% of common ventilation duct problems. For professional operations involving circuit modification, system debugging, etc., it is still necessary to contact qualified engineering personnel to ensure safe operation.
