什么是風管，常見風管有哪些類型，風管主要指中央空調系統的通風管道，它常常被忽視，但配件卻是空調系統的重要組成部分。風管是由薄鋼板、鋁板、硬聚氯乙烯板、玻璃鋼以及其它復合材料等制成的，推薦配件用(yong)于輸送空氣和空氣混合物的各種管(guan)(guan)(guan)(guan)道的總稱(cheng)。1、按(an)照材質可(ke)(ke)分(fen)為(wei)(wei)(wei)(wei)：金(jin)屬(shu)(shu)(shu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、非金(jin)屬(shu)(shu)(shu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)。其中：（1）金(jin)屬(shu)(shu)(shu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)又可(ke)(ke)分(fen)為(wei)(wei)(wei)(wei)：鋼板風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、鋁板風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、不銹鋼風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)等；（2）非金(jin)屬(shu)(shu)(shu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可(ke)(ke)以(yi)(yi)分(fen)為(wei)(wei)(wei)(wei)：硬聚(ju)氯乙烯(xi)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、有機(ji)玻璃風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、無機(ji)玻璃風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、玻璃鋼風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)以(yi)(yi)及其它(ta)復(fu)合材料(liao)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)等；2、按(an)照風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)外形可(ke)(ke)分(fen)為(wei)(wei)(wei)(wei)：圓形風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、矩(ju)形風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)；3、按(an)照通風(feng)(feng)(feng)(feng)(feng)(feng)(feng)空調系(xi)統工(gong)作壓力可(ke)(ke)分(fen)為(wei)(wei)(wei)(wei)：高壓風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、中壓風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、低壓風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)三個類別，

現階(jie)(jie)段是(shi)很多雞(ji)舍(she)(she)都配備了通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)，我是(shi)2013年開始用(yong)的通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)，在(zai)使用(yong)過程中，曾(ceng)經出現過很多問(wen)題(ti)，現總結(jie)一下(xia)，歡迎拍磚交(jiao)流(liu)。一，通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)的作(zuo)用(yong)。1降低(di)操作(zuo)負(fu)壓。冬季沒安裝通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)的雞(ji)舍(she)(she)，使用(yong)小(xiao)窗(chuang)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)，尤其是(shi)跨度大的雞(ji)舍(she)(she)為了導風(feng)(feng)(feng)(feng)(feng)(feng)(feng)合理安全，使用(yong)高負(fu)壓通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)。而(er)使用(yong)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)道(dao)(dao)，由(you)(you)于進風(feng)(feng)(feng)(feng)(feng)(feng)(feng)在(zai)管(guan)道(dao)(dao)內基(ji)本(ben)不擴散，低(di)負(fu)壓下(xia)都是(shi)按(an)照風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)方(fang)向，依次從開口(kou)處出風(feng)(feng)(feng)(feng)(feng)(feng)(feng)。2位置高，出風(feng)(feng)(feng)(feng)(feng)(feng)(feng)均勻。進風(feng)(feng)(feng)(feng)(feng)(feng)(feng)雖(sui)然在(zai)管(guan)道(dao)(dao)內沒有預(yu)熱，但下(xia)落位置高，向下(xia)擴散時間就是(shi)預(yu)熱過程。3跟風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)配合合理配置，在(zai)初始開啟風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)階(jie)(jie)段，由(you)(you)于設計問(wen)題(ti)導致進風(feng)(feng)(feng)(feng)(feng)(feng)(feng)窗(chuang)使用(yong)不安全，可以利用(yong)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)管(guan)過渡。

風機(ji)(ji)分類可(ke)(ke)以(yi)(yi)按(an)氣(qi)(qi)體流(liu)動(dong)(dong)(dong)的方向，分為離(li)心式、軸(zhou)流(liu)式、斜流(liu)式和(he)(he)橫流(liu)式等類型。這種風機(ji)(ji)分類的機(ji)(ji)器有(you)：離(li)心風機(ji)(ji)工作(zuo)時(shi)，動(dong)(dong)(dong)力機(ji)(ji)(主(zhu)要是(shi)電(dian)動(dong)(dong)(dong)機(ji)(ji))驅動(dong)(dong)(dong)葉(xie)(xie)輪(lun)在(zai)(zai)蝸形機(ji)(ji)殼內旋轉，空氣(qi)(qi)經吸氣(qi)(qi)口從葉(xie)(xie)輪(lun)中心處吸入。由(you)于葉(xie)(xie)片(pian)對氣(qi)(qi)體的動(dong)(dong)(dong)力作(zuo)用(yong)，氣(qi)(qi)體壓力和(he)(he)速(su)度得以(yi)(yi)提(ti)高，并在(zai)(zai)離(li)心力作(zuo)用(yong)下沿著(zhu)葉(xie)(xie)道甩向機(ji)(ji)殼，從排氣(qi)(qi)口排出(chu)。因氣(qi)(qi)體在(zai)(zai)葉(xie)(xie)輪(lun)內的流(liu)動(dong)(dong)(dong)主(zhu)要是(shi)在(zai)(zai)徑向平面內，故又(you)稱徑流(liu)風機(ji)(ji)。離(li)心風機(ji)(ji)主(zhu)要由(you)葉(xie)(xie)輪(lun)和(he)(he)機(ji)(ji)殼組成，小(xiao)型風機(ji)(ji)的葉(xie)(xie)輪(lun)直(zhi)接(jie)裝在(zai)(zai)電(dian)動(dong)(dong)(dong)機(ji)(ji)上中、大型風機(ji)(ji)通過聯軸(zhou)器或(huo)皮帶輪(lun)與電(dian)動(dong)(dong)(dong)機(ji)(ji)聯接(jie)。離(li)心風機(ji)(ji)一般為單側進(jin)氣(qi)(qi)，用(yong)單級葉(xie)(xie)輪(lun)；流(liu)量大的可(ke)(ke)雙(shuang)側進(jin)氣(qi)(qi)，用(yong)兩個背靠背的葉(xie)(xie)輪(lun)，又(you)稱為雙(shuang)吸式離(li)心風機(ji)(ji)。

在(zai)葉(xie)輪運轉初期及所有(you)定期檢查的時候(hou)，只要一(yi)有(you)機(ji)會，都必(bi)須檢查葉(xie)輪是否出現裂(lie)紋、磨損、積(ji)塵(chen)等缺陷。只要有(you)可能，都必(bi)須使(shi)葉(xie)輪保持清潔狀態(tai)，并(bing)定期用(yong)鋼絲刷(shua)刷(shua)去上面的積(ji)塵(chen)和(he)銹皮(pi)等，因為(wei)隨著(zhu)運行(xing)時間(jian)(jian)的加長，這些(xie)灰塵(chen)由(you)于不可能均勻(yun)地附著(zhu)在(zai)葉(xie)輪上，而造(zao)成(cheng)葉(xie)輪平衡(heng)破壞，以至引起轉子(zi)振動(dong)。葉(xie)輪只要進(jin)行(xing)了(le)修理(li)，就需要對其再作動(dong)平衡(heng)。如有(you)條(tiao)件(jian)，可以使(shi)用(yong)便攜(xie)試(shi)動(dong)平衡(heng)儀在(zai)現場進(jin)行(xing)平衡(heng)。在(zai)作動(dong)平衡(heng)之前，必(bi)須檢查所有(you)緊(jin)定螺栓是否上緊(jin)。因為(wei)葉(xie)輪已(yi)(yi)經在(zai)不平衡(heng)狀態(tai)下運行(xing)了(le)一(yi)段(duan)時間(jian)(jian)，這些(xie)螺栓可能已(yi)(yi)經松(song)動(dong)。
