正压送风机在消防体系中起到的感化

文(wen)章来由:未知 人气:颁发时(shi)候(hou):2018-08-10
  正压送风机消防排烟(yan)风(feng)机都属于消防举措方法,应当能够或许完成联动透风装备网。在消防节制室的主动消防体系节制柜处于主动状况时,当火警主动报警的感烟探头、感温探头同时举措时,防火卷帘应当联动封闭,位于分散通道处时,应完成两步降。下降时,应当有旌旗灯号反应到消防节制室。当火警确认后,消防节制室应能节制正压送风机、防排烟风机举措,对处于分散通道、防烟楼梯间等部位的职员必然的防护感化。

    正压(ya)(ya)(ya)送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)是(shi)指向逃生(sheng)楼(lou)道里送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)。它(ta)将室外风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)压(ya)(ya)(ya)送(song)(song)(song)入室内。当修建(jian)物发(fa)生(sheng)火警时(shi),会(hui)发(fa)生(sheng)大(da)(da)批(pi)(pi)烟(yan)雾、一氧(yang)化碳(tan)等(deng)有毒气体(ti)并遮(zhe)挡视野,经由(you)过程正压(ya)(ya)(ya)送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)放风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)阀给逃生(sheng)的(de)(de)(de)消防(fang)楼(lou)梯送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng),使室内的(de)(de)(de)烟(yan)雾不(bu)能到达(da)楼(lou)梯,给人们(men)逃生(sheng)缔造前(qian)提。正压(ya)(ya)(ya)送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)通俗装于修建(jian)物顶,与各层(ceng)的(de)(de)(de)正压(ya)(ya)(ya)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)阀联动。火警早期时(shi)翻开风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)阀,启动正压(ya)(ya)(ya)送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji),使楼(lou)梯间、电(dian)梯厅处于正压(ya)(ya)(ya)状况(送(song)(song)(song)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)状况)。 一、SWF系列混(hun)流(liu)式(shi)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)概述 SWF系列混(hun)流(liu)式(shi)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)具备同机(ji)(ji)(ji)号(hao)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)量(liang)(liang)较(jiao)离(li)心(xin)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)大(da)(da),风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)压(ya)(ya)(ya)较(jiao)轴(zhou)流(liu)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)高(gao),能够轴(zhou)向装置(zhi)(zhi)(zhi)等(deng)特色;噪声(sheng)低(di)、耗电(dian)省、高(gao)效区宽、装置(zhi)(zhi)(zhi)利用(yong)(yong)较(jiao)离(li)心(xin)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)便利、运(yun)(yun)转(zhuan)(zhuan)靠得(de)住等(deng)。 二、SWF系列混(hun)流(liu)式(shi)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)特色 1.布局(ju)松散、装置(zhi)(zhi)(zhi)便利、运(yun)(yun)转(zhuan)(zhuan)靠得(de)住;该(gai)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)在(zai)不(bu)异风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)量(liang)(liang)、风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)压(ya)(ya)(ya)的(de)(de)(de)环境下(xia)(xia)均比轴(zhou)流(liu)式(shi)或(huo)离(li)心(xin)式(shi)体(ti)积小, 可间接(jie)与风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)筒毗连(lian),程度装置(zhi)(zhi)(zhi)或(huo)垂直装置(zhi)(zhi)(zhi),操(cao)纵利用(yong)(yong)便利的(de)(de)(de)特色。 2.噪声(sheng)低(di):该(gai)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)的(de)(de)(de)外壳经出(chu)格设(she)想、可较(jiao)大(da)(da)地下(xia)(xia)降外流(liu)噪声(sheng)。在(zai)单元(yuan)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)量(liang)(liang)、单元(yuan)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)压(ya)(ya)(ya)的(de)(de)(de)工(gong)(gong)况前(qian)提下(xia)(xia)、 比A声(sheng)级可下(xia)(xia)降2-3dB(A),同时(shi)在(zai)较(jiao)低(di)转(zhuan)(zhuan)速(su)的(de)(de)(de)环境下(xia)(xia),可取得(de)较(jiao)高(gao)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)压(ya)(ya)(ya)力。在(zai)工(gong)(gong)矿企业和(he)高(gao)等(deng) 民用(yong)(yong)修建(jian)的(de)(de)(de)送(song)(song)(song)排风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)体(ti)系中可取代高(gao)压(ya)(ya)(ya)离(li)心(xin)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)或(huo)取代高(gao)压(ya)(ya)(ya)轴(zhou)流(liu)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)而不(bu)须要大(da)(da)批(pi)(pi)消声(sheng)方法。 3.合用(yong)(yong)规模广(guang):本系列产物分(fen)单速(su)和(he)双速(su)两种型号(hao),可按照差别(bie)的(de)(de)(de)利用(yong)(yong)场所,转(zhuan)(zhuan)变(bian)(bian)风(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)机(ji)(ji)(ji)的(de)(de)(de)装置(zhi)(zhi)(zhi)角 度,转(zhuan)(zhuan)变(bian)(bian)叶片(pian)数(shu)和(he)变(bian)(bian)更转(zhuan)(zhuan)速(su)到达(da)其利用(yong)(yong)请求。
