渝中值得信賴的通風管道廠家

消防排煙風機風量與送風機風量計算方法是根據建筑面積來確定的，每個防煙分區都需要獨立計算其排煙量，當排煙風機擔負一個防煙分區的時候可按平方米面積不小于60m3／h計算，擔負多個防煙分區則按平方米面積不小于120m3／h計算。送風量按排煙量的50%計算。每個防煙分區不應大于500平方。常見的消防防排煙系統中，排煙量一般根據大防煙分區面積500*120等于60000立方每小時計算，在通風管道設計排煙量的時候要注意漏風量，一般可按小漏風量10%計算。例如：當建筑面積為1000平方時，通風管道廠家需(xu)要(yao)設(she)置兩(liang)個防煙(yan)分區，每個防煙(yan)分區的(de)大(da)面積為500平方，排煙(yan)量(liang)(liang)是(shi)500*1203／h=600003／h，再加上(shang)小漏(lou)風量(liang)(liang)10%為60003／h，總排煙(yan)量(liang)(liang)應為660003／h，其中(zhong)送風量(liang)(liang)為排煙(yan)量(liang)(liang)的(de)50%應為330003／h。

鑒于軸(zhou)(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)(ji)有(you)紊流(liu)(liu)(liu)區(qu)的(de)(de)性能(neng)特點(dian)(dian)，在選型和(he)使(shi)用時，需(xu)要注意以(yi)下(xia)兩點(dian)(dian)：建(jian)議使(shi)用在空曠(kuang)環(huan)境(jing)中,軸(zhou)(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)(ji)的(de)(de)輸入(ru)(ru)功(gong)率(lv)隨系統(tong)靜壓的(de)(de)增大(da)(da)而增大(da)(da)，而在紊流(liu)(liu)(liu)區(qu)，輸入(ru)(ru)功(gong)率(lv)的(de)(de)增大(da)(da)幅度會更大(da)(da)。因此(ci)，軸(zhou)(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)(ji)一(yi)般多應(ying)用在有(you)較大(da)(da)空曠(kuang)環(huan)境(jing)的(de)(de)場合(he)下(xia)，可以(yi)使(shi)其工作在靜壓較低的(de)(de)環(huan)境(jing)下(xia)，降低功(gong)耗，保證(zheng)穩定性和(he)壽命(ming)。定期(qi)清理風(feng)(feng)道,當軸(zhou)(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)(ji)應(ying)用在較為封(feng)閉的(de)(de)風(feng)(feng)道系統(tong)中時，長期(qi)運行后(hou)風(feng)(feng)道中的(de)(de)積灰(hui)、垃圾逐漸(jian)變多，會使(shi)風(feng)(feng)道內(nei)的(de)(de)靜壓逐漸(jian)增加，使(shi)得風(feng)(feng)機(ji)(ji)的(de)(de)運行工況點(dian)(dian)逐漸(jian)左(zuo)移。這(zhe)不(bu)僅會降低風(feng)(feng)機(ji)(ji)性能(neng)，更重要的(de)(de)是會增加軸(zhou)(zhou)流(liu)(liu)(liu)風(feng)(feng)機(ji)(ji)進入(ru)(ru)紊流(liu)(liu)(liu)區(qu)的(de)(de)風(feng)(feng)險(xian)。因此(ci)必須要定期(qi)清理風(feng)(feng)道，保證(zheng)風(feng)(feng)機(ji)(ji)工況點(dian)(dian)不(bu)產(chan)生較大(da)(da)偏移。
