具有消防排煙風機和通風換氣的(de)兩用(yong)(yong)功用(yong)(yong)，具有用(yong)(yong)率高(gao)(gao)、噪聲(sheng)低、裝置便利、運行(xing)平穩、流(liu)量大、耐高(gao)(gao)溫(wen)(wen)等特(te)色，是高(gao)(gao)層建筑用(yong)(yong)消(xiao)防(fang)高(gao)(gao)溫(wen)(wen)排煙(yan)風機(ji)更新換代產品，箱(xiang)板(ban)采(cai)用(yong)(yong)冷軋鋼板(ban)折彎而成，為雙(shuang)層復式(shi)結構(gou)，內部(bu)填(tian)裝防(fang)火保溫(wen)(wen)材料(liao)，以避免高(gao)(gao)溫(wen)(wen)度(du)環境下發生(sheng)結露現象，更能有用(yong)(yong)降噪減振(zhen)。消(xiao)防(fang)高(gao)(gao)溫(wen)(wen)排煙(yan)風機(ji)生(sheng)產廠家(jia)依據高(gao)(gao)檔民用(yong)(yong)建筑的(de)不同要求，采(cai)用(yong)(yong)變速或多速驅(qu)動形(xing)式(shi)，以到達一機(ji)兩用(yong)(yong)（即常用(yong)(yong)通排風和消(xiao)防(fang)使用(yong)(yong)時高(gao)(gao)溫(wen)(wen)排煙(yan)）的(de)目的(de)。

風機(ji)基本形式(shi)為(wei)軸(zhou)流(liu)風機(ji)，可采(cai)用于風管(guan)連(lian)接和(he)壁式(shi)裝置（裝置形式(shi)可筆直(zhi)或水平式(shi)），很大(da)程(cheng)度地節(jie)省(sheng)了占地面積。調試前應先查看(kan)供應消防高溫排煙(yan)風機(ji)用的電(dian)(dian)源及電(dian)(dian)壓各項是否(fou)(fou)符(fu)合要(yao)求(qiu)(qiu)，電(dian)(dian)源是否(fou)(fou)缺相或同相位，所配電(dian)(dian)器元(yuan)件的容量(liang)是否(fou)(fou)符(fu)合要(yao)求(qiu)(qiu)。查看(kan)風管(guan)閥門開閉狀況，確(que)定管(guan)道內無雜物存在。停機(ji)查看(kan)風機(ji)是否(fou)(fou)有異(yi)常現(xian)象(xiang)，承(cheng)認(ren)無異(yi)常現(xian)象(xiang)再開機(ji)工(gong)作。

消(xiao)防高溫(wen)排煙(yan)風機(ji)(ji)到達正(zheng)(zheng)常轉(zhuan)速時，應丈量風機(ji)(ji)輸入電(dian)(dian)(dian)(dian)流(liu)是(shi)否正(zheng)(zheng)常，風機(ji)(ji)的運行電(dian)(dian)(dian)(dian)流(liu)不(bu)能超(chao)越(yue)其(qi)額(e)定電(dian)(dian)(dian)(dian)流(liu)。若運行電(dian)(dian)(dian)(dian)流(liu)超(chao)越(yue)其(qi)額(e)定電(dian)(dian)(dian)(dian)流(liu)，應查(cha)看供應的電(dian)(dian)(dian)(dian)壓是(shi)否正(zheng)(zheng)常。消(xiao)防高溫(wen)排煙(yan)風機(ji)(ji)廠家試機(ji)(ji)時將風機(ji)(ji)進口或(huo)出口管路上的閥(fa)(fa)門(men)關閉，工(gong)作后將閥(fa)(fa)門(men)漸漸開啟，到達所(suo)需工(gong)況停止，并(bing)注(zhu)意風機(ji)(ji)的工(gong)作電(dian)(dian)(dian)(dian)流(liu)是(shi)否超(chao)越(yue)額(e)定電(dian)(dian)(dian)(dian)流(liu)。

消防高溫排煙風機的(de)供配電(dian)達(da)不(bu)到(dao)高層民用(yong)建筑負荷級別要(yao)求。有的(de)供電(dian)線路不(bu)是(shi)接自(zi)消防電(dian)探(tan)，而是(shi)接至樓層照明配電(dian)箱，有的(de)規劃采用(yong)單回(hui)路配電(dian)線路，有的(de)規劃未設結尾(wei)電(dian)源(yuan)自(zi)動(dong)切換(huan)裝置，均達(da)不(bu)到(dao)一、二級供電(dian)負荷要(yao)求的(de)專用(yong)雙回(hui)路。
