負壓(ya)(ya)風(feng)(feng)(feng)機的(de)(de)工(gong)作原理：負壓(ya)(ya)風(feng)(feng)(feng)機向(xiang)外排(pai)風(feng)(feng)(feng)，降低(di)室(shi)內(nei)空(kong)氣(qi)(qi)(qi)(qi)壓(ya)(ya)力，使(shi)室(shi)內(nei)空(kong)氣(qi)(qi)(qi)(qi)變薄(bo)，形(xing)成負壓(ya)(ya)區。空(kong)氣(qi)(qi)(qi)(qi)由(you)于(yu)氣(qi)(qi)(qi)(qi)壓(ya)(ya)差的(de)(de)補償而流入(ru)房間(jian)(jian)。在工(gong)業廠(chang)房的(de)(de)實(shi)際應用(yong)中，負壓(ya)(ya)風(feng)(feng)(feng)機集中安裝(zhuang)在廠(chang)房一側(ce)，進(jin)風(feng)(feng)(feng)口在廠(chang)房另(ling)一側(ce)。空(kong)氣(qi)(qi)(qi)(qi)從進(jin)風(feng)(feng)(feng)口對流吹入(ru)負壓(ya)(ya)風(feng)(feng)(feng)機。 在此過程中，負壓(ya)(ya)風(feng)(feng)(feng)扇(shan)附近(jin)的(de)(de)門窗保持關閉狀態，通(tong)過補償進(jin)氣(qi)(qi)(qi)(qi)口側(ce)面的(de)(de)門窗，迫使(shi)空(kong)氣(qi)(qi)(qi)(qi)流入(ru)車間(jian)(jian)。空(kong)氣(qi)(qi)(qi)(qi)從進(jin)風(feng)(feng)(feng)口依(yi)次流入(ru)車間(jian)(jian)，經過車間(jian)(jian)，由(you)負壓(ya)(ya)風(feng)(feng)(feng)機排(pai)出車間(jian)(jian)。通(tong)風(feng)(feng)(feng)高效，換氣(qi)(qi)(qi)(qi)率高達99%。 通(tong)過具體(ti)的(de)(de)工(gong)程設計(ji)(ji)，根據需要設計(ji)(ji)通(tong)風(feng)(feng)(feng)速(su)度(du)和風(feng)(feng)(feng)速(su)，任(ren)何(he)高熱、有害氣(qi)(qi)(qi)(qi)體(ti)、灰塵和煙霧都能迅速(su)從車間(jian)(jian)排(pai)出，任(ren)何(he)通(tong)風(feng)(feng)(feng)不良的(de)(de)問題都能一勞(lao)永逸地解決(jue)。通(tong)風(feng)(feng)(feng)效果可以在打開風(feng)(feng)(feng)扇(shan)的(de)(de)幾秒鐘內(nei)實(shi)現(xian)。
