風機是依靠輸入的機械能，提高氣體壓力并排送氣體的機械，它是一種從動的流體機械。風機的性能參數主要有流量、壓力、功率、效率和轉速。另外，噪聲和振動的大小也是主要的風機設計指標。
    Fans are machines that rely on input mechanical energy to increase gas pressure and send gas side-by-side. It is a driven fluid machinery. The performance parameters of fan are mainly flow, pressure, power, efficiency and speed. In addition, noise and vibration are also the main design indicators of fans.
    油煙凈化設備安裝系統里常見的風機有幾種？它們又都有什么特點呢？離心風機和軸流風機之間又有什么區別呢？
    How many kinds of fans are there in the installation system of lampblack purification equipment? What are the characteristics of them? What is the difference between centrifugal fans and axial fans?

    離心風機：一般用于工業油霧凈化器安裝現場、或廚房油煙凈化器管道相對比較復雜的安裝現場；
    Centrifugal fan: generally used for the installation site of industrial oil mist cleaner, or for the relatively complicated installation of kitchen fume purifier pipeline.
    軸流風機：用于廚房油煙凈化設備現場，一般用于補鮮風；
    Axial fan: used for kitchen fume purification equipment, usually used for fresh air supply.
    風柜：用于廚房油煙凈化設備現場，一般用于抽廚房油煙。
    Wind cabinet: used for kitchen fume purification equipment on-site, generally used for cooking kitchen fumes.
    離心風機和軸流風機主要區別在于：
    The main difference between the centrifugal fan and the axial fan is that:
    1、離心風機改變了風管內介質的流向，而軸流風機不改變風管內介質的流向；
    The centrifugal fan changes the flow direction of the medium in the duct, while the axial flow fan does not change the flow direction of the medium in the duct.
    2、離心風機安裝比較復雜 ，軸流風機安裝比較簡單、直接串聯在風管上即可；
    centrifugal fan installation is more complicated, axial fan installation is relatively simple, directly connected in series on the wind pipe.
    3、離心風機的電機與風機一般是通過軸連接的，軸流風機的電機一般在風機內；
    the centrifugal fan's motor and fan are usually connected by shaft, and the motor of axial fan is usually in the fan.
    4、離心風機風壓較大，一般用于比較復雜的現場作為引風機。軸流風機常安裝在風管當中、或風管出口前端。
    The centrifugal fan has high wind pressure and is generally used as a draught fan for more complicated fields. Axial fans are often installed in the duct or at the front end of the outlet.
