消防排煙風機廠家產品由多個配件構成，比如說葉輪、機殼、軸承、主軸等等構成，而通風設備不同的配件也起著不同的作用。首先對于葉輪而言，一般采用優質鍍鋅板制作而成的葉片，通過傾斜設計，與拉伸成型的前盤一起形成了更合理的流道，從而保證了葉輪的高效率。而軸承是帶鑄造座的外球面軸承，可以通過外球面配合調整同軸度的誤差。主軸一般采用45#鋼經調制處理后精車而成，保證足夠的光潔度和尺寸精。另外兩層板內部填充消聲材料，推薦通風設備能更有效隔(ge)熱降(jiang)噪。消防(fang)(fang)排煙風(feng)(feng)機不(bu)能距離隧(sui)(sui)道(dao)(dao)的(de)(de)邊壁太近，避免(mian)影響通(tong)(tong)風(feng)(feng)效果(guo)。通(tong)(tong)風(feng)(feng)系統從(cong)安全隧(sui)(sui)道(dao)(dao)向(xiang)通(tong)(tong)過橫(heng)通(tong)(tong)道(dao)(dao)向(xiang)事(shi)故(gu)隧(sui)(sui)道(dao)(dao)方向(xiang)送(song)風(feng)(feng)，抑制煙氣進(jin)入橫(heng)通(tong)(tong)道(dao)(dao)及未發(fa)生事(shi)故(gu)的(de)(de)隧(sui)(sui)道(dao)(dao)，滿(man)足疏散人員迎著新風(feng)(feng)進(jin)入橫(heng)通(tong)(tong)道(dao)(dao)和安全隧(sui)(sui)道(dao)(dao)內，同時(shi)保證等待區域所需要的(de)(de)新鮮(xian)空氣。充分利用定點(dian)救援站處的(de)(de)斜井和隧(sui)(sui)道(dao)(dao)兩端的(de)(de)消防(fang)(fang)排煙風(feng)(feng)機作(zuo)為送(song)入新風(feng)(feng)和排煙的(de)(de)通(tong)(tong)道(dao)(dao)，通(tong)(tong)風(feng)(feng)必須維持橫(heng)通(tong)(tong)道(dao)(dao)口處于正壓狀態(tai)，防(fang)(fang)止煙氣流向(xiang)通(tong)(tong)道(dao)(dao)內。

消防(fang)排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)風(feng)(feng)機(ji)風(feng)(feng)量(liang)(liang)(liang)與送風(feng)(feng)機(ji)風(feng)(feng)量(liang)(liang)(liang)計算方(fang)法是(shi)根據建筑面(mian)積(ji)來確定(ding)的(de)(de)，每個(ge)(ge)防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)都需(xu)要獨立計算其(qi)排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)，當排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)風(feng)(feng)機(ji)擔(dan)負一個(ge)(ge)防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)的(de)(de)時(shi)候(hou)可按平(ping)方(fang)米(mi)(mi)面(mian)積(ji)不小(xiao)于60m3／h計算，擔(dan)負多個(ge)(ge)防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)則(ze)按平(ping)方(fang)米(mi)(mi)面(mian)積(ji)不小(xiao)于120m3／h計算。送風(feng)(feng)量(liang)(liang)(liang)按排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)的(de)(de)50%計算。每個(ge)(ge)防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)不應大于500平(ping)方(fang)。常見(jian)的(de)(de)消防(fang)防(fang)排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)系統中，排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)一般(ban)(ban)根據大防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)面(mian)積(ji)500*120等于60000立方(fang)每小(xiao)時(shi)計算，在(zai)設(she)計排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)的(de)(de)時(shi)候(hou)要注意漏風(feng)(feng)量(liang)(liang)(liang)，一般(ban)(ban)可按小(xiao)漏風(feng)(feng)量(liang)(liang)(liang)10%計算。例如：當建筑面(mian)積(ji)為1000平(ping)方(fang)時(shi)，需(xu)要設(she)置兩個(ge)(ge)防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)，每個(ge)(ge)防(fang)煙(yan)(yan)(yan)(yan)(yan)分區(qu)的(de)(de)大面(mian)積(ji)為500平(ping)方(fang)，排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)是(shi)500*1203／h=600003／h，再加上小(xiao)漏風(feng)(feng)量(liang)(liang)(liang)10%為60003／h，總排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)應為660003／h，其(qi)中送風(feng)(feng)量(liang)(liang)(liang)為排(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)(liang)(liang)的(de)(de)50%應為330003／h。
