<p>隨著(zhù)科技的發(fā)展，消防排煙3C設備的使用越來(lái)越廣泛，由于消防排煙3C設備的選型不像軸流風(fēng)機和離心風(fēng)機的使用那么熟練，因此對于一些客戶(hù)來(lái)說(shuō)，對于如何選型問(wèn)題必然會(huì )比較困難。為了進(jìn)一步提高用戶(hù)對它的了解，我們對它的相關(guān)內容做了如下介紹：</p><p><br/></p><p>1、選擇3C消防排煙風(fēng)機時(shí)，首先要了解其工作溫度、風(fēng)量、總壓、功率、噪聲、電機功率、轉速和軸功率。</p><p><br/></p><p>2、選用的3C消防排煙風(fēng)機應能在介質(zhì)溫度不高于85℃的條件下長(cháng)期正常工作。</p><p><br/></p><p>3、3C消防排煙風(fēng)機在介質(zhì)溫度為280℃時(shí)可連續工作30分鐘℃, 當介質(zhì)溫度冷卻到環(huán)境溫度時(shí)也能正常工作。</p><p><br/></p><p>4、在額外轉速條件下，風(fēng)機在工作區的實(shí)測壓力曲線(xiàn)和規范中給出的曲線(xiàn)應符合下列規定：</p><p><br/></p><p>a）在常規流量下，軸流排風(fēng)機的壓力誤差為±5%。</p><p><br/></p><p>b）在常規流量下，離心式排風(fēng)機的壓力誤差為±5%。</p><p><br/></p><p>5、3C消防排煙風(fēng)機可采用普通鋼制離心風(fēng)機或專(zhuān)用排煙軸流風(fēng)機，下限風(fēng)量為7200m/h，風(fēng)量不宜超過(guò)60000m/h（指一個(gè)排煙區風(fēng)量）。</p><p><br/></p><p>6、防煙增壓風(fēng)機按排煙系統和不良氣體回路計算風(fēng)壓值，確保防煙樓梯間余壓值為40-50pa，前室、合用前室、消防電梯前室、避難層余壓為25-30pa。</p><p><br/></p><p>7、3c消防排煙風(fēng)機的朝向應在排煙區的同一樓層或上層。</p><p><br/></p>
