The main structural components of the fan are impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts (bearings), etc. The unpowered fan uses the air heat convection caused by the natural wind and the indoor and outdoor temperature difference to drive the turbine to rotate so as to use the centrifugal force and negative pressure effect to exhaust the indoor fresh hot air.

風機關系到系統的輸配能耗，是建筑節能非常關鍵的部分。根據國家空調設備質量監督檢驗多年風機檢測表明很多風機在額定工況下都存在問題，因此需要嚴格按照產品標準要求生產和制造風機。風機剛開始工作時軸承部位的振動很小，但是隨著運轉時間的加長。

Fan is related to the energy consumption of transmission and distribution of the system, and is a very important part of building energy saving. According to the national air conditioning equipment quality supervision and Inspection Center for many years, fan testing shows that many fans have problems under rated conditions, so it is necessary to produce and manufacture fans in strict accordance with product standards. At the beginning of the fan, the vibration of the bearing is very small, but it increases with the running time.

風機內粉塵會不均勻的附著在葉輪上，逐漸破壞風機的動平衡，使軸承振動逐漸加大，一旦振動達到風機允許的值11mm/s時（用振幅值表示的允許值如下），風機必須停機修理（清除粉塵堆積，重做動平衡）。因為這時已是非常危險的，用戶千萬不可強行使用。在風機振動接近危險值時，有測振儀表的會報警。

The dust in the fan will adhere to the impeller unevenly, and gradually destroy the dynamic balance of the fan, so that the bearing vibration will gradually increase. Once the vibration reaches the maximum value of 11mm / s allowed by the fan (the maximum allowable value expressed by the amplitude value is as follows), the fan must be shut down for repair (remove the dust accumulation, and do the dynamic balance again). Because it is very dangerous at this time, users must not use it forcibly. When the fan vibration is close to the dangerous value, the vibration measuring instrument will give an alarm.

風機的軸承溫度正常時為≤70℃，如果一旦升高到70℃，有電控的應（會）報警。此時應查找原因，首先檢查冷卻水是否正常？軸承油位是否正常？如果一時找不到原因，軸承溫度迅速上升到90℃，有電控的應（會）再次發出報警、停車信號，風機開車、停車或運轉過程中，如發現不正常現象應立即進行檢查，檢查發現的小故障應及時查明原因設法消除。

When the bearing temperature of the fan is normal, it is ≤ 70 ℃. If it rises to 70 ℃, the fan with electric control shall (will) give an alarm. At this time, the reason should be found out. First, check whether the cooling water is normal? Is the bearing oil level normal? If the cause cannot be found for a while, the bearing temperature will rise rapidly to 90 ℃. If there is electric control, the alarm and stop signal shall be sent again. In the process of fan start-up, stop or operation, if abnormal phenomenon is found, it shall be checked immediately, and the small fault found in the check shall be found out in time to eliminate the cause.
