化工實驗室通風系統安裝施工過程：

首(shou)先應(ying)準備(bei)：通(tong)(tong)風設備(bei)、通(tong)(tong)風管道、消聲器、風機、控制(zhi)系統。

通(tong)(tong)風(feng)(feng)設(she)備我(wo)們一般都是選用通(tong)(tong)風(feng)(feng)柜(ju)，通(tong)(tong)風(feng)(feng)柜(ju)有分標準型(xing)通(tong)(tong)風(feng)(feng)柜(ju)，落(luo)地型(xing)通(tong)(tong)風(feng)(feng)柜(ju)，桌(zhuo)上型(xing)通(tong)(tong)風(feng)(feng)柜(ju)，補風(feng)(feng)型(xing)通(tong)(tong)風(feng)(feng)柜(ju)

通風柜的材質分為：全鋼通風柜、鋼木通風柜、不銹鋼通風柜、PP通風柜、鋁木通風柜、全木通風柜，一般化工實驗室選用全鋼通(tong)風(feng)柜(ju)比較多。

通(tong)風(feng)(feng)管道：分為PVC、PP、玻(bo)璃(li)鋼三種材(cai)質，用的最多是(shi)PVC材(cai)質，我們一般在做化工實驗(yan)室通(tong)風(feng)(feng)系(xi)統的時候(hou)選(xuan)用PP。

消聲器：是(shi)為了減少通風系統在(zai)運行(xing)的(de)噪(zao)音，一般選(xuan)用PVC、PP、玻(bo)璃鋼(gang)(gang)，選(xuan)用PP、跟玻(bo)璃鋼(gang)(gang)的(de)比較多，PVC焊接會不牢固(gu)，一般很少選(xuan)用。

控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)(xi)統(tong)：通(tong)風(feng)(feng)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)(xi)統(tong)可根據不同(tong)的情況采用不同(tong)的控(kong)(kong)(kong)制(zhi)(zhi)(zhi)方式，如單臺(tai)通(tong)風(feng)(feng)設備(bei)定制(zhi)(zhi)(zhi)風(feng)(feng)量通(tong)風(feng)(feng)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)(xi)統(tong)、多(duo)臺(tai)通(tong)風(feng)(feng)設備(bei)變頻通(tong)風(feng)(feng)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)(xi)統(tong)、多(duo)臺(tai)通(tong)風(feng)(feng)設備(bei)變頻+變風(feng)(feng)量通(tong)風(feng)(feng)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)(xi)統(tong)。

單臺通(tong)(tong)(tong)風(feng)(feng)(feng)設備定風(feng)(feng)(feng)量控制(zhi)系統是指(zhi)每一(yi)臺通(tong)(tong)(tong)風(feng)(feng)(feng)柜的(de)排風(feng)(feng)(feng)由(you)獨立的(de)一(yi)組通(tong)(tong)(tong)風(feng)(feng)(feng)管和一(yi)臺風(feng)(feng)(feng)機，有效(xiao)的(de)排放于大氣層(ceng)，風(feng)(feng)(feng)機的(de)開關、排風(feng)(feng)(feng)系統的(de)啟動(dong)(dong)安裝于通(tong)(tong)(tong)風(feng)(feng)(feng)柜或通(tong)(tong)(tong)風(feng)(feng)(feng)設備上，通(tong)(tong)(tong)風(feng)(feng)(feng)柜上方的(de)控制(zhi)閥(fa)為電動(dong)(dong)閥(fa)或手動(dong)(dong)閥(fa)。

此種通風系統優點：

1. 操作簡捷，系統(tong)的開關不(bu)影響同一(yi)個房間的設(she)備，只引用需要的通(tong)風設(she)備。

2. 防止通風系(xi)統的(de)串聯(lian)及廢氣的(de)回流。

3. 便(bian)于氣流的控制。

4. 系統動作的費(fei)用比較低。
