我(wo)總(zong)結(jie)了風(feng)扇電(dian)(dian)機(ji)的(de)(de)幾個常(chang)見(jian)問(wen)題，希望能(neng)對閉(bi)(bi)式冷(leng)卻塔風(feng)機(ji)用戶有所幫(bang)助(zhu)。電(dian)(dian)機(ji)裕(yu)度較(jiao)大，閉(bi)(bi)式冷(leng)卻塔風(feng)機(ji)運行。這是一個常(chang)見(jian)問(wen)題，風(feng)扇通常(chang)以(yi)(yi)高速和(he)(he)低負載運行。風(feng)機(ji)振動(dong)(dong)(dong)(dong)大，現(xian)場(chang)噪(zao)音大，工作環(huan)境惡劣。當擋板(ban)調整到10%以(yi)(yi)下(xia)(xia)時(shi)，管(guan)道會因負壓過(guo)大而喘振，危及設(she)備的(de)(de)安(an)(an)全(quan)運行。無(wu)論(lun)在什么(me)環(huan)境下(xia)(xia)，人(ren)身安(an)(an)全(quan)和(he)(he)設(she)備安(an)(an)全(quan)都很(hen)重要(yao)。直(zhi)接啟動(dong)(dong)(dong)(dong)時(shi)，閉(bi)(bi)式冷(leng)卻塔風(feng)機(ji)的(de)(de)啟動(dong)(dong)(dong)(dong)電(dian)(dian)流很(hen)高，可能(neng)導致高壓電(dian)(dian)源(yuan)進線保護(hu)動(dong)(dong)(dong)(dong)作，電(dian)(dian)機(ji)無(wu)法連續啟動(dong)(dong)(dong)(dong)。這就要(yao)求用戶在啟動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)時(shi)要(yao)充(chong)分注(zhu)意電(dian)(dian)源(yuan)的(de)(de)電(dian)(dian)流和(he)(he)額(e)定電(dian)(dian)壓，使(shi)電(dian)(dian)機(ji)能(neng)夠在正常(chang)環(huan)境下(xia)(xia)啟動(dong)(dong)(dong)(dong)。
