排煙(yan)風(feng)機的電流怎么控制(zhi)!
如(ru)何解決排煙風(feng)(feng)機(ji)的(de)(de)電流過大(da)的(de)(de)問題, 消防風(feng)(feng)機(ji)的(de)(de)性(xing)(xing)(xing)能(neng)(neng)(neng)表中列出的(de)(de)性(xing)(xing)(xing)能(neng)(neng)(neng)是(shi)最高效(xiao)率(lv)范圍(wei)內的(de)(de)性(xing)(xing)(xing)能(neng)(neng)(neng),按(an)風(feng)(feng)量(liang)分為五(wu)個性(xing)(xing)(xing)能(neng)(neng)(neng)點,選用時按(an)性(xing)(xing)(xing)能(neng)(neng)(neng)表為準(zhun)。出廠的(de)(de)消防風(feng)(feng)機(ji)合格品(pin)是(shi)在額定(ding)風(feng)(feng)量(liang)下,全壓值誤差不(bu)超過±5%、 性(xing)(xing)(xing)能(neng)(neng)(neng)選用表是(shi)標準(zhun)狀(zhuang)態下的(de)(de)性(xing)(xing)(xing)能(neng)(neng)(neng),無論技術(shu)文件或定(ding)貨要求(qiu)的(de)(de)。
消防排煙風機的電動機(ji)輸(shu)入電壓過低或(huo)電源單向斷電,要及時(shi)檢查電壓,電源是否正(zheng)常;聯軸器連接(jie)不正(zheng),皮圈過緊或(huo)間隙不均,要重(zhong)新(xin)調整(zheng)找正(zheng)
當(dang)風機的皮帶軸安裝不(bu)當(dang),消耗無用功過(guo)多,也(ye)要重新調(diao)整找(zhao)正;如果(guo)碰(peng)到通風機聯(lian)合工(gong)作(zuo)(zuo)惡化(hua)或(huo)管網故障(zhang),一定要調(diao)整風機聯(lian)合工(gong)作(zuo)(zuo)的工(gong)作(zuo)(zuo)點,檢修管網系統。
如果在開(kai)車時進口管(guan)道閘閥未(wei)關(guan)(guan)嚴,要注意(yi)開(kai)車是要關(guan)(guan)嚴閘閥;當(dang)流量(liang)超過額定值或風(feng)管(guan)漏氣,要關(guan)(guan)小節流閥,檢查是否(fou)漏氣!
排(pai)煙風機調(diao)試八大注意事項:
1、風機允許(xu)全壓(ya)起動(dong)或降壓(ya)啟動(dong),但應注意,全壓(ya)起動(dong)時(shi)的電流(liu)約為5-7倍的額定電流(liu),降壓(ya)起動(dong)轉(zhuan)距與電壓(ya)平(ping)方成正(zheng)比(bi),當電網容量(liang)不足時(shi),應采用降壓(ya)起動(dong)。(當功(gong)率大于11KW時(shi),宜采用降壓(ya)起動(dong))。
2、風機在試(shi)車時,應認(ren)真閱讀產(chan)品說明書,檢(jian)查接線方法是(shi)否(fou)同接線圖相符;應認(ren)真檢(jian)查供(gong)給風機電源的(de)工作電壓是(shi)不(bu)是(shi)符合要求,電源是(shi)否(fou)缺相或同相位,所配電器元件(jian)的(de)容量是(shi)否(fou)符合要求。
3、試車時人少于兩人,一人控制電源(yuan),一人觀察風機(ji)(ji)運轉情況(kuang),發(fa)現(xian)(xian)異(yi)(yi)常(chang)現(xian)(xian)象(xiang)立即停(ting)機(ji)(ji)檢(jian)(jian)查(cha);首先檢(jian)(jian)查(cha)旋轉方向是(shi)否(fou)正確(que);風機(ji)(ji)開始運轉后,應立即運轉電流(liu)(liu)是(shi)否(fou)平(ping)衡、電流(liu)(liu)是(shi)否(fou)超過額定電流(liu)(liu);若有不(bu)正常(chang)現(xian)(xian)象(xiang),應停(ting)機(ji)(ji)檢(jian)(jian)查(cha)。運轉五分(fen)鐘后,停(ting)機(ji)(ji)檢(jian)(jian)查(cha)風機(ji)(ji)是(shi)否(fou)有異(yi)(yi)常(chang)現(xian)(xian)象(xiang),確(que)認無(wu)異(yi)(yi)常(chang)現(xian)(xian)象(xiang)再開機(ji)(ji)運轉。
4、雙速(su)風機試車時(shi),應先起動(dong)(dong)低速(su),并(bing)檢查(cha)旋(xuan)轉(zhuan)(zhuan)方(fang)向是否正確;起動(dong)(dong)高(gao)速(su)時(shi)必須待風機靜(jing)止后再(zai)起動(dong)(dong),以防高(gao)速(su)反向旋(xuan)轉(zhuan)(zhuan),引起開(kai)關跳閘及電機受(shou)損。
5、排(pai)煙風(feng)機達到正常轉速(su)時,應測量(liang)風(feng)機運行電(dian)(dian)(dian)流(liu)(liu)是(shi)否正常,風(feng)機的運行電(dian)(dian)(dian)流(liu)(liu)不能(neng)超(chao)過(guo)其(qi)額定電(dian)(dian)(dian)流(liu)(liu)。若(ruo)運行電(dian)(dian)(dian)流(liu)(liu)超(chao)過(guo)其(qi)額定電(dian)(dian)(dian)流(liu)(liu),應檢查供給風(feng)機的電(dian)(dian)(dian)壓是(shi)否正常。
