風(fēng)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(fēng)機的性能參數(shù)主要有流量、壓力、功率、效率和轉(zhuǎn)速。另外，噪聲和振動的大小也是主要的風(fēng)機設(shè)計指標(biāo)。
    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(shè)備安裝系統(tǒng)里常見的風(fēng)機有幾種？它們又都有什么特點呢？離心風(fēng)機和軸流風(fēng)機之間又有什么區(qū)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(fēng)機：一般用于工業(yè)油霧凈化器安裝現(xiàn)場、或廚房油煙凈化器管道相對比較復(fù)雜的安裝現(xiàn)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(fēng)機：用于廚房油煙凈化設(shè)備現(xiàn)場，一般用于補鮮風(fēng)；
    Axial fan: used for kitchen fume purification equipment, usually used for fresh air supply.
    風(fēng)柜：用于廚房油煙凈化設(shè)備現(xiàn)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(fēng)機和軸流風(fēng)機主要區(qū)別在于：
    The main difference between the centrifugal fan and the axial fan is that:
    1、離心風(fēng)機改變了風(fēng)管內(nèi)介質(zhì)的流向，而軸流風(fēng)機不改變風(fēng)管內(nèi)介質(zhì)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(fēng)機安裝比較復(fù)雜 ，軸流風(fēng)機安裝比較簡單、直接串聯(lián)在風(fēng)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(fēng)機的電機與風(fēng)機一般是通過軸連接的，軸流風(fēng)機的電機一般在風(fēng)機內(nèi)；
    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(fēng)機風(fēng)壓較大，一般用于比較復(fù)雜的現(xiàn)場作為引風(fēng)機。軸流風(fēng)機常安裝在風(fēng)管當(dāng)中、或風(fēng)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.
