如何(hé)區(qū)分正壓送風機和消防排煙風(fēng)機

 

記得以前匯弘小編和大家說過,風機大體被分為兩大類,一種是離心風(fēng)機,而另一種(zhǒng)是軸流風機。但按(àn)照功能再細製劃分的話(huà),還會分出很多,比如消防排煙風(fēng)機、正壓送風風機(jī)、廚房排油煙風(fēng)機、除塵風機、高壓風機、鍋爐引風機等等(děng),而今天小編要和大家說的是正壓送風風機和消防排煙風機(jī)應該如何區分,蕾丝视频官网在選擇風(fēng)機的時候,如何分清楚應該選擇的是正壓送風風機還是消防(fáng)排煙風機,下麵匯弘小編就(jiù)詳細的(de)來和大家講解一下。

1、定義區別:

  正壓送風機主要是一種可以將空氣從外麵(miàn)吹到裏麵的風機。一般(bān)室內壓力(lì)高於室外壓力,普通風機無(wú)法將空氣從室外送入(rù)室內,因此在建築(zhù)現場,風機是室內通風(fēng)的主要設備。此外,送風機還用於向避難建築供氣(qì)。一旦發生火災,會產(chǎn)生大量的煙霧、一氧化碳等有毒氣體,遮擋視(shì)線,通過風機將空氣(qì)吹入(rù)方艙消(xiāo)防樓梯,使室內煙霧無法到達樓梯,為人們創造(zào)避難條件。

  消防排煙風機是指適用於“高層建築、地下建築、隧道及公共場所”等,可用於通風和高溫排(pái)煙的風機。另外,根據(jù)消防要求,消防風機要(yào)在280°等高溫條件下連(lián)續工作30分鍾以上(shàng),即使連續工作20小時也不會損(sǔn)壞。平均溫度為100°C 時的時間。

  2、功能區別:

  在防煙排煙係(xì)統中,送風機常用(yòng)於防煙係統,主要(yào)用(yòng)於對建築物內(nèi)部(bù)進行加(jiā)壓送風。通常,它可以對建築物內部的空氣進行加壓(yā),以(yǐ)保證建築物內的空氣流通。發生火災時(shí),室外的新鮮空氣也可以通過送風管道吹入樓梯間,使煙霧和有毒(dú)氣體不擴散到消防管道,使人員及時逃生。

  在排煙和防(fáng)煙係統中,消防排煙風機一般用於排煙係統。當發(fā)生火災時(shí),消(xiāo)防風機可以在有效時間內將建築物內的煙霧和有毒氣體排除,使(shǐ)人員能夠(gòu)順利逃生。

  3、安裝位置不同(tóng)

  正壓風機主要(yào)用於防煙係統,安裝在通風管道內。它通常與防火閥組合使用,形成防煙係統。

  消防排煙風機主要用於排風係統,安裝在排風(fēng)管道內。排煙器和排(pái)煙通(tōng)常相互組合使用,組成一個(gè)排煙係統。

  以上就是(shì)正壓送風機消防排煙風機(jī)的(de)區別。兩者在使用過程中區別並不明顯,主要是功能和安(ān)裝場所有些區(qū)別,主要功能是排煙。所(suǒ)以(yǐ)在使用(yòng)安裝過程中分清哪根管道是送風係統,哪根(gēn)管道是排煙係統,這樣就會很清晰的分辨出哪裏應該安裝正(zhèng)壓送風風(fēng)機,哪裏(lǐ)應該安裝排煙風機了(le)。
