排煙(yan)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)(xiang)廠家(jia)(jia)選用(yong)控(kong)制參數(shu)為風(feng)(feng)(feng)(feng)(feng)(feng)量、全壓(ya)(ya)、功(gong)率、噪聲以及(ji)電(dian)機(ji)(ji)功(gong)率等。排煙(yan)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)(xiang)廠家(jia)(jia)廠家(jia)(jia)由于設置了排煙(yan)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)(xiang)廠家(jia)(jia)，有利于消聲。排煙(yan)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)(xiang)廠家(jia)(jia)選型時(shi)，應考(kao)慮管路體系(xi)的漏風(feng)(feng)(feng)(feng)(feng)(feng)丟(diu)掉(diao)、計算誤差(cha)(cha)，以及(ji)排煙(yan)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)(xiang)廠家(jia)(jia)實(shi)踐風(feng)(feng)(feng)(feng)(feng)(feng)量、風(feng)(feng)(feng)(feng)(feng)(feng)壓(ya)(ya)的負偏差(cha)(cha)，一般選用(yong)風(feng)(feng)(feng)(feng)(feng)(feng)量為1.05～1.1，風(feng)(feng)(feng)(feng)(feng)(feng)壓(ya)(ya)為1.10～1.15 的系(xi)數(shu)。但也不(bu)選用(yong)過大，以防(fang)止(zhi)排煙(yan)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)箱(xiang)(xiang)廠家(jia)(jia)長期處在低功(gong)率區(qu)工(gong)作。
排煙(yan)風機(ji)(ji)箱價(jia)格(ge)安裝前，應對風機(ji)(ji)各部(bu)(bu)件(jian)進(jin)行(xing)檢(jian)查。機(ji)(ji)件(jian)是(shi)(shi)否完(wan)整(zheng)，葉輪與(yu)機(ji)(ji)殼的旋轉方向是(shi)(shi)否一致(zhi)，各部(bu)(bu)聯接(jie)是(shi)(shi)否嚴密，葉輪、主軸、軸承等(deng)首(shou)要機(ji)(ji)件(jian)有(you)無(wu)損害，傳動組是(shi)(shi)否靈敏等(deng)等(deng)。如發現問(wen)題，應立(li)即予以修好和調(diao)整(zheng)
