? 為了使其在空間環境中有杰出的使用,就要在挑選上多下功夫,對柜式風機箱選(xuan)用(yong)(yong)關鍵,首(shou)要在(zai)于風(feng)(feng)(feng)機(ji)(ji)箱選(xuan)用(yong)(yong)操控(kong)參數(shu)為(wei)風(feng)(feng)(feng)量(liang)、全壓、功率、噪(zao)聲以及(ji)電機(ji)(ji)功率等。有(you)離(li)心式(shi)和軸流式(shi),一(yi)般(ban)通(tong)風(feng)(feng)(feng)機(ji)(ji)因為(wei)設置了柜式(shi)風(feng)(feng)(feng)機(ji)(ji)箱,有(you)利于消聲,在(zai)對通(tong)風(feng)(feng)(feng)機(ji)(ji)進行選(xuan)型的時分(fen),應考慮管路(lu)體(ti)系的漏(lou)風(feng)(feng)(feng)丟失(shi)、計算差(cha)錯,以及(ji)通(tong)風(feng)(feng)(feng)機(ji)(ji)實踐(jian)風(feng)(feng)(feng)量(liang)、風(feng)(feng)(feng)壓的負(fu)差(cha)錯,一(yi)般(ban)選(xuan)用(yong)(yong)風(feng)(feng)(feng)量(liang)為(wei)1.05~1.1,風(feng)(feng)(feng)壓為(wei)1.10~1.15 的安全系數(shu)。
在對柜式(shi)風機(ji)箱進(jin)行試車的(de)(de)時分,一定(ding)要仔(zi)細(xi)閱讀產品(pin)說明,查(cha)(cha)察接線過(guo)程與(yu)接線圖是(shi)(shi)不(bu)是(shi)(shi)符(fu)合(he)(he)(he);還(huan)應(ying)該過(guo)細(xi)查(cha)(cha)察供給(gei)風機(ji)電(dian)(dian)(dian)(dian)源的(de)(de)電(dian)(dian)(dian)(dian)壓是(shi)(shi)不(bu)是(shi)(shi)切合(he)(he)(he)要求,電(dian)(dian)(dian)(dian)源是(shi)(shi)不(bu)是(shi)(shi)缺相(xiang)或(huo)同相(xiang)位,所(suo)配電(dian)(dian)(dian)(dian)器元件的(de)(de)容量是(shi)(shi)不(bu)是(shi)(shi)切合(he)(he)(he)要求,然后柜式(shi)風機(ji)箱抵達正常轉速時應(ying)測(ce)量風機(ji)輸入電(dian)(dian)(dian)(dian)流(liu)是(shi)(shi)不(bu)是(shi)(shi)正常,柜式(shi)風機(ji)箱的(de)(de)電(dian)(dian)(dian)(dian)流(liu)不(bu)能(neng)超越其額定(ding)電(dian)(dian)(dian)(dian)流(liu)。若電(dian)(dian)(dian)(dian)流(liu)超越其額定(ding)電(dian)(dian)(dian)(dian)流(liu)應(ying)查(cha)(cha)察供給(gei)的(de)(de)電(dian)(dian)(dian)(dian)壓是(shi)(shi)不(bu)是(shi)(shi)正常。
對柜(ju)式風機(ji)(ji)(ji)箱(xiang)和(he)電(dian)機(ji)(ji)(ji)的裝置,在檢(jian)修時沒(mei)有找正,柜(ju)式風機(ji)(ji)(ji)箱(xiang)和(he)電(dian)機(ji)(ji)(ji)的兩軸用聯(lian)軸器聯(lian)接時,軸向誤差和(he)徑(jing)向誤差超(chao)差很大,使整個機(ji)(ji)(ji)組產生巨大的振蕩,從(cong)而使軸變形。
在裝置和檢(jian)修(xiu)柜(ju)式(shi)風(feng)機箱時,依照(zhao)技能要求將離(li)心式(shi)柜(ju)式(shi)風(feng)機箱與(yu)電機兩軸(zhou)的平行度和同心度控制(zhi)在0.05-0.1mm之間(jian),兩聯軸(zhou)器中心應(ying)留有5-6mm空隙。這樣,工軸(zhou)彎曲折斷的故障就得到了(le)完(wan)全修(xiu)理。
柜式風機箱根據噪(zao)聲(sheng)等級能夠(gou)分為(wei):超低噪(zao)聲(sheng)離(li)(li)心風(feng)機箱(xiang)、低噪(zao)聲(sheng)離(li)(li)心風(feng)機箱(xiang)、普通(tong)型離(li)(li)心風(feng)機箱(xiang)等。目前多數風(feng)機箱(xiang)出產廠家都(dou)標榜自己出產的(de)(de)風(feng)機箱(xiang)產品為(wei)超低噪(zao)聲(sheng)型,不過實(shi)際使用(yong)還(huan)要看詳細(xi)參數規范,滿意工(gong)況要求才能夠(gou)。現(xian)在的(de)(de)風(feng)機箱(xiang)工(gong)藝(yi)都(dou)在箱(xiang)體加(jia)上了消音棉和消聲(sheng)器(qi)的(de)(de)配(pei)件,能夠(gou)挑選正規廠家的(de)(de)產品裝置。
