重慶推薦防火閥批發

風(feng)(feng)管(guan)(guan)(guan)主(zhu)要指中央空調系(xi)統的(de)(de)通風(feng)(feng)管(guan)(guan)(guan)道，它(ta)常常被忽視，但(dan)卻是空調系(xi)統的(de)(de)重要組成部分，目前常見的(de)(de)風(feng)(feng)管(guan)(guan)(guan)主(zhu)要有四種：1）鍍鋅(xin)(xin)薄(bo)鋼板風(feng)(feng)管(guan)(guan)(guan)；2)無(wu)機玻(bo)璃(li)鋼風(feng)(feng)管(guan)(guan)(guan)；3)復(fu)合(he)玻(bo)纖板風(feng)(feng)管(guan)(guan)(guan)；4)纖維織(zhi)物風(feng)(feng)管(guan)(guan)(guan)。鍍鋅(xin)(xin)薄(bo)鋼板風(feng)(feng)管(guan)(guan)(guan)：早使用(yong)的(de)(de)風(feng)(feng)管(guan)(guan)(guan)，采用(yong)鍍鋅(xin)(xin)薄(bo)鋼板制(zhi)作，適合(he)含濕量(liang)小的(de)(de)一般性氣體的(de)(de)輸送，有易(yi)生(sheng)銹，無(wu)保(bao)溫(wen)和消聲功能，制(zhi)作安(an)(an)裝周(zhou)期(qi)長的(de)(de)特點。無(wu)機玻(bo)璃(li)鋼風(feng)(feng)管(guan)(guan)(guan)：較(jiao)新的(de)(de)風(feng)(feng)管(guan)(guan)(guan)類型，采用(yong)玻(bo)璃(li)纖維增強無(wu)機材料(liao)制(zhi)作，遇火不(bu)燃(ran)、耐腐(fu)蝕(shi)、份量(liang)重，硬度大但(dan)較(jiao)脆，受自重影(ying)響易(yi)變形(xing)酥裂，無(wu)保(bao)溫(wen)和消聲性能，制(zhi)作安(an)(an)裝周(zhou)期(qi)長。

鑒于軸流風機有紊流區的性能特點，在選型和使用時，需要注意以下兩點：重慶防火閥建議使用在空曠環境中,軸流風機的輸入功率隨系統靜壓的增大而增大，而在紊流區，輸入功率的增大幅度會更大。因此，軸流風機一般多應用在有較大空曠環境的場合下，可以使其工作在靜壓較低的環境下，降低功耗，保證穩定性和壽命。防火閥批發定期(qi)(qi)清理(li)風(feng)(feng)(feng)道(dao),當軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)應用在(zai)較為封閉(bi)的(de)(de)風(feng)(feng)(feng)道(dao)系統中(zhong)時，長期(qi)(qi)運行后風(feng)(feng)(feng)道(dao)中(zhong)的(de)(de)積(ji)灰、垃圾(ji)逐(zhu)漸變多，會(hui)使風(feng)(feng)(feng)道(dao)內(nei)的(de)(de)靜壓逐(zhu)漸增加，使得風(feng)(feng)(feng)機(ji)的(de)(de)運行工況點逐(zhu)漸左移(yi)。這不僅(jin)會(hui)降低風(feng)(feng)(feng)機(ji)性(xing)能，更重要的(de)(de)是會(hui)增加軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)進(jin)入紊流(liu)區(qu)的(de)(de)風(feng)(feng)(feng)險。因此必(bi)須要定期(qi)(qi)清理(li)風(feng)(feng)(feng)道(dao)，保(bao)證(zheng)風(feng)(feng)(feng)機(ji)工況點不產生較大偏移(yi)。
