工業(ye)大(da)風扇的使(shi)用(yong)(yong)與維(wei)護往(wang)往(wang)被人(ren)們所忽略，一臺工業(ye)大(da)風扇能(neng)否發揮最大(da)經(jing)濟效益，延長使(shi)用(yong)(yong)壽命(ming)等，正(zheng)確使(shi)用(yong)(yong)與日常維(wei)護是(shi)個關鍵(jian)性問題(ti)。

(1)起(qi)動(dong)：工(gong)業大(da)(da)風(feng)扇(shan)在起(qi)動(dong)前(qian)首(shou)先應(ying)(ying)進行(xing)機械方面的(de)(de)(de)檢查(cha)(cha)，如檢查(cha)(cha)轉(zhuan)軸是(shi)否靈活;軸承應(ying)(ying)有適當潤滑;風(feng)扇(shan)與風(feng)罩不能(neng)相撞，工(gong)業大(da)(da)風(feng)扇(shan)底座固定率等。然后必須(xu)以電(dian)路(lu)方面檢查(cha)(cha)，加檢查(cha)(cha)工(gong)業大(da)(da)風(feng)扇(shan)的(de)(de)(de)引線(xian)(xian)是(shi)否接對。有的(de)(de)(de)工(gong)業大(da)(da)風(feng)扇(shan)出線(xian)(xian)盒中只有兩根(gen)線(xian)(xian)，這種容(rong)易接對，有的(de)(de)(de)有四根(gen)線(xian)(xian)，這時一定按有關說明書的(de)(de)(de)接法(fa)進行(xing)，否則會燒壞工(gong)業大(da)(da)風(feng)扇(shan)。線(xian)(xian)頭必須(xu)接牢;在工(gong)業大(da)(da)風(feng)扇(shan)的(de)(de)(de)插座前(qian)最好(hao)安裝保(bao)險(xian)絲(si)，保(bao)險(xian)絲(si)的(de)(de)(de)安培定額應(ying)(ying)比(bi)電(dian)動(dong)機的(de)(de)(de)安培定額約(yue)高10——25%。

工業大風(feng)扇(shan)在運轉前(qian)，最(zui)好(hao)不(bu)帶負載進行空載試轉一次，察看(kan)轉動是(shi)否(fou)正常，轉向(xiang)是(shi)否(fou)符合要求等(deng)。單相工業大風(feng)扇(shan)的轉向(xiang)。廠家已把繞(rao)組(zu)接好(hao)，不(bu)易隨意改動。

工業大風扇(shan)起動(dong)時(shi)(shi)一般3——5秒即可起動(dong)完畢(bi)，若(ruo)超過(guo)這個(ge)時(shi)(shi)間工業大風扇(shan)轉(zhuan)不(bu)(bu)起來或達不(bu)(bu)到70——80%額定轉(zhuan)速時(shi)(shi)，應(ying)迅速切斷電源，檢(jian)查故障(zhang)原(yuan)因，切不(bu)(bu)可遲延(yan)，否則(ze)易燒壞繞(rao)組(zu)。這種情況可能(neng)是負(fu)載(zai)過(guo)大;電壓較低.離心開關不(bu)(bu)動(dong)作，工業大風扇(shan)繞(rao)組(zu)有問題等(deng)。

(2)運(yun)(yun)行(xing)(xing)：工(gong)(gong)業大(da)風(feng)扇帶負載正常運(yun)(yun)轉時轉速均勻，聲音適(shi)中(zhong)，發(fa)熱適(shi)當。但(dan)要經常注意工(gong)(gong)業大(da)風(feng)扇溫(wen)升(sheng)情況，若發(fa)現(xian)嚴重(zhong)發(fa)熱及其(qi)它不(bu)(bu)良癥狀必需(xu)拉閘停止(zhi)運(yun)(yun)行(xing)(xing)。多(duo)半在(zai)農村由于電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)壓降低(di)出現(xian)此種(zhong)情況，這(zhe)種(zhong)發(fa)熱雖一時不(bu)(bu)會燒壞(huai)繞組，但(dan)要降低(di)工(gong)(gong)業大(da)風(feng)扇使(shi)用壽命。要保證工(gong)(gong)業大(da)風(feng)扇防(fang)潮及通風(feng)良好，出線(xian)盒及電(dian)(dian)(dian)(dian)容(rong)(rong)器等(deng)(deng)(deng)處不(bu)(bu)能進水，也不(bu)(bu)能有機械損傷。風(feng)罩的避(bi)風(feng)口(kou)不(bu)(bu)能堵塞，工(gong)(gong)業大(da)風(feng)扇外殼應良好接地等(deng)(deng)(deng)。電(dian)(dian)(dian)(dian)容(rong)(rong)器損壞(huai)更新時，新電(dian)(dian)(dian)(dian)容(rong)(rong)器的電(dian)(dian)(dian)(dian)壓值不(bu)(bu)得低(di)于舊電(dian)(dian)(dian)(dian)容(rong)(rong)器的電(dian)(dian)(dian)(dian)壓值，其(qi)做法數(shu)最好相等(deng)(deng)(deng)。

(3)維修：工(gong)業(ye)大風扇(shan)運行(xing)相(xiang)當(dang)長(chang)一段時(shi)間可以(yi)拆開維修。清理(li)內部雜(za)物灰(hui)塵，填加潤(run)(run)滑油(用(yong)鈣(gai)鈉(na)基1號潤(run)(run)滑脂)等;最(zui)好用(yong)500伏級搖表測量繞(rao)組(zu)絕緣電阻，正常的應不小于0.5兆歐。

而大(da)(da)(da)型車間(jian)場所所使(shi)用的(de)工(gong)業(ye)(ye)(ye)(ye)(ye)節能風(feng)(feng)(feng)扇(shan)(shan)通(tong)常使(shi)用減(jian)速工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)一體(ti)機(ji)，減(jian)速工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)一體(ti)機(ji)是指減(jian)速機(ji)和工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)(馬(ma)達)的(de)集(ji)成(cheng)體(ti)。這(zhe)種集(ji)成(cheng)體(ti)通(tong)常也(ye)可稱為齒輪(lun)馬(ma)達或齒輪(lun)工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)。通(tong)常由專(zhuan)業(ye)(ye)(ye)(ye)(ye)的(de)減(jian)速機(ji)生產廠進行(xing)(xing)集(ji)成(cheng)組(zu)裝(zhuang)好后成(cheng)套供(gong)貨。減(jian)速工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)廣泛應(ying)用于(yu)鋼鐵行(xing)(xing)業(ye)(ye)(ye)(ye)(ye)、機(ji)械行(xing)(xing)業(ye)(ye)(ye)(ye)(ye)等(deng)。使(shi)用減(jian)速工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)的(de)優點是簡化(hua)設計、節省(sheng)空間(jian)。作為同行(xing)(xing)業(ye)(ye)(ye)(ye)(ye)的(de)佼佼者，SEW一直致力于(yu)研發更高(gao)效、更節能的(de)系(xi)列減(jian)速工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)。也(ye)是眾多(duo)工(gong)業(ye)(ye)(ye)(ye)(ye)節能風(feng)(feng)(feng)扇(shan)(shan)工(gong)業(ye)(ye)(ye)(ye)(ye)大(da)(da)(da)風(feng)(feng)(feng)扇(shan)(shan)使(shi)用的(de)首選品牌(pai)。

拆裝時(shi)應注(zhu)意：①繞組內部接(jie)線(xian)，離心(xin)開(kai)關的(de)焊(han)接(jie)點等不得弄(nong)錯(cuo)或斷開(kai)，②不準(zhun)碰(peng)破(po)繞組絕(jue)緣(yuan)，保護好(hao)離心(xin)開(kai)關的(de)動作(zuo)間隙，確保其觸(chu)頭正常動作(zuo)，其觸(chu)點有(you)火(huo)花燒斑(ban)時(shi)，可用細破(po)布輕(qing)輕(qing)打(da)磨。③對鋁(lv)殼(ke)工(gong)業(ye)大風(feng)扇應注(zhu)意避免重擊，保護好(hao)工(gong)業(ye)大風(feng)扇端面止口，切勿將機殼(ke)、端蓋上的(de)散(san)熱(re)筋損(sun)壞，以保持良好(hao)的(de)散(san)熱(re)條件。風(feng)扇葉(xie)不能(neng)碰(peng)彎碰(peng)斷，軸承(cheng)及轉軸不得有(you)機械損(sun)傷(shang)等。工(gong)業(ye)大風(feng)扇貯(zhu)存(cun)時(shi)，應放在通風(feng)干燥(zao)處。
