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：涪陵消防風機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。消防風機價格定(ding)期(qi)清理風(feng)(feng)道,當(dang)軸流(liu)風(feng)(feng)機(ji)應用在較(jiao)為封閉(bi)的(de)風(feng)(feng)道系統(tong)中時(shi)，長期(qi)運行后風(feng)(feng)道中的(de)積灰、垃(la)圾逐(zhu)漸(jian)(jian)(jian)變(bian)多(duo)，會使風(feng)(feng)道內的(de)靜壓逐(zhu)漸(jian)(jian)(jian)增加，使得風(feng)(feng)機(ji)的(de)運行工況點逐(zhu)漸(jian)(jian)(jian)左移。這(zhe)不(bu)僅(jin)會降低(di)風(feng)(feng)機(ji)性能，更(geng)重(zhong)要的(de)是會增加軸流(liu)風(feng)(feng)機(ji)進入紊流(liu)區的(de)風(feng)(feng)險(xian)。因此(ci)必(bi)須要定(ding)期(qi)清理風(feng)(feng)道，保證風(feng)(feng)機(ji)工況點不(bu)產生較(jiao)大偏移。

在空調(diao)送(song)(song)風(feng)(feng)(feng)(feng)系(xi)統中(zhong)(zhong)，空調(diao)送(song)(song)風(feng)(feng)(feng)(feng)機(ji)送(song)(song)出的(de)風(feng)(feng)(feng)(feng)必須通過主干(gan)(gan)管(guan)(guan)(guan)分配(pei)到(dao)(dao)支管(guan)(guan)(guan)中(zhong)(zhong)；在排(pai)(pai)煙(yan)(yan)(yan)系(xi)統中(zhong)(zhong)，煙(yan)(yan)(yan)氣由支管(guan)(guan)(guan)到(dao)(dao)主干(gan)(gan)管(guan)(guan)(guan)后(hou)，進入排(pai)(pai)煙(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)排(pai)(pai)出。當建筑(zhu)物(wu)內(nei)發生(sheng)火(huo)(huo)(huo)(huo)災時(shi)(shi)，在通風(feng)(feng)(feng)(feng)、空調(diao)系(xi)統中(zhong)(zhong)，為(wei)了防止(zhi)火(huo)(huo)(huo)(huo)勢(shi)通過送(song)(song)風(feng)(feng)(feng)(feng)系(xi)統蔓延，當送(song)(song)風(feng)(feng)(feng)(feng)系(xi)統中(zhong)(zhong)氣體溫(wen)度(du)達到(dao)(dao)70℃時(shi)(shi)，防火(huo)(huo)(huo)(huo)閥機(ji)構上(shang)熔斷(duan)器(qi)動作(zuo)，閥門(men)亦迅速關(guan)閥，切斷(duan)煙(yan)(yan)(yan)氣與火(huo)(huo)(huo)(huo)勢(shi)沿風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)蔓延的(de)通路。同樣，在排(pai)(pai)煙(yan)(yan)(yan)系(xi)統中(zhong)(zhong)，發生(sheng)火(huo)(huo)(huo)(huo)災時(shi)(shi)，排(pai)(pai)煙(yan)(yan)(yan)閥開(kai)啟，進行排(pai)(pai)煙(yan)(yan)(yan)，為(wei)了截斷(duan)高(gao)溫(wen)煙(yan)(yan)(yan)氣在排(pai)(pai)煙(yan)(yan)(yan)管(guan)(guan)(guan)路中(zhong)(zhong)流動，防止(zhi)火(huo)(huo)(huo)(huo)勢(shi)蔓延到(dao)(dao)另一防火(huo)(huo)(huo)(huo)分區(qu)，當排(pai)(pai)出的(de)煙(yan)(yan)(yan)氣溫(wen)度(du)達到(dao)(dao)280℃時(shi)(shi)，排(pai)(pai)煙(yan)(yan)(yan)防火(huo)(huo)(huo)(huo)閥、排(pai)(pai)煙(yan)(yan)(yan)口上(shang)熔斷(duan)器(qi)動作(zuo)，閥門(men)必須自動關(guan)閉，阻止(zhi)排(pai)(pai)煙(yan)(yan)(yan)。由此可見(jian)，防火(huo)(huo)(huo)(huo)閥、排(pai)(pai)煙(yan)(yan)(yan)閥做到(dao)(dao)了該通則通，該斷(duan)則斷(duan)的(de)隔煙(yan)(yan)(yan)阻火(huo)(huo)(huo)(huo)作(zuo)用。
