離心風機用在很多地方，主要由葉輪、機殼、聯軸器、軸等部件組成。其中，葉輪是產生風壓和傳遞能量的主要工作部件；外殼主要用于引入氣體和廢氣，同時將氣體的部分動能轉變為壓力能；聯軸器用于連接電機和風扇以傳遞扭矩。軸安裝并固定葉輪，葉輪通過聯軸器與電機連接。
Centrifugal fans are used in many places and mainly consist of components such as impellers, casings, couplings, and shafts. Among them, the impeller is the main working component that generates wind pressure and transmits energy; The shell is mainly used to introduce gas and exhaust gas, while converting some of the kinetic energy of the gas into pressure energy; The coupling is used to connect the motor and fan to transmit torque. Install and fix the impeller on the shaft, and the impeller is connected to the motor through a coupling.
離心風機停止時，關閉風機的主制動器，并通知電氣人員拆除與離心風機連接的電氣設備，如溫度、振動等，做好標記并妥善保管。脫開聯軸器，取下風機外殼法蘭上的定位銷，取下螺栓；拆下軸承座與風機上半殼之間的連接螺栓，用起重機吊起上半殼。
When the centrifugal fan stops, turn off the main brake of the fan and notify the electrical personnel to remove the electrical equipment connected to the centrifugal fan, such as temperature, vibration, etc., mark and properly store them. Disconnect the coupling, remove the locating pin on the flange of the fan casing, and remove the bolt; Remove the connecting bolts between the bearing seat and the upper half of the fan casing, and use a crane to lift the upper half of the casing.
