涪陵推薦通風設備批發

風機分類可以按氣體流動的方向，分為離心式、軸流式、斜流式和橫流式等類型。這種風機分類的機器有：離心風機工作時，動力機(主要是電動機)驅動葉輪在蝸形機殼內旋轉，空氣經吸氣口從葉輪中心處吸入。由于通風設備葉片對氣體的動力作用，氣體壓力和速度得以提高，并在離心力作用下沿著葉道甩向機殼，推薦通風設備從排氣口(kou)排出。因氣體在葉輪(lun)(lun)內的(de)流動主要是在徑向平面內，故又稱(cheng)徑流風(feng)機(ji)(ji)(ji)。離心(xin)風(feng)機(ji)(ji)(ji)主要由葉輪(lun)(lun)和機(ji)(ji)(ji)殼(ke)組成，小型(xing)(xing)風(feng)機(ji)(ji)(ji)的(de)葉輪(lun)(lun)直接(jie)裝在電動機(ji)(ji)(ji)上中、大(da)型(xing)(xing)風(feng)機(ji)(ji)(ji)通過聯(lian)軸器或皮帶輪(lun)(lun)與電動機(ji)(ji)(ji)聯(lian)接(jie)。離心(xin)風(feng)機(ji)(ji)(ji)一(yi)般為單側(ce)進(jin)(jin)氣，用單級(ji)葉輪(lun)(lun)；流量大(da)的(de)可雙側(ce)進(jin)(jin)氣，用兩個背靠背的(de)葉輪(lun)(lun)，又稱(cheng)為雙吸(xi)式離心(xin)風(feng)機(ji)(ji)(ji)。
