屋頂風機啟動調試的方法
1. 電(dian)壓(ya)調(diao)試。 風機(ji)允許全壓(ya)起動(dong)(dong)或降(jiang)壓(ya)起動(dong)(dong),但應(ying)注意,全壓(ya)起動(dong)(dong)時(shi)的電(dian)流為5~7倍的額定電(dian)流,降(jiang)壓(ya)起動(dong)(dong)轉(zhuan)距與電(dian)壓(ya)平方(fang)成正比,當電(dian)網容量不足時(shi),應(ying)采用降(jiang)壓(ya)起動(dong)(dong)。(當功率大于(yu)11KW時(shi),宜(yi)采用降(jiang)壓(ya)起動(dong)(dong))。
2. 運轉(zhuan)調試(shi)(shi)。 試(shi)(shi)車(che)時人數(shu)不(bu)(bu)少于兩人,一人控制電(dian)源,一人觀察風(feng)機(ji)(ji)運轉(zhuan)情況(kuang),發現(xian)異常(chang)現(xian)象(xiang)立即停(ting)機(ji)(ji)檢(jian)查(cha);首(shou)先檢(jian)查(cha)旋轉(zhuan)方向(xiang)是否正(zheng)確;風(feng)機(ji)(ji)過程(cheng)中,應檢(jian)查(cha)各相運轉(zhuan)電(dian)流(liu)(liu)是否平衡,電(dian)流(liu)(liu)是否超過額定電(dian)流(liu)(liu);若(ruo)有(you)(you)不(bu)(bu)正(zheng)常(chang)現(xian)象(xiang),應停(ting)止檢(jian)查(cha)。運轉(zhuan)五分(fen)鐘(zhong)后(hou),停(ting)機(ji)(ji)檢(jian)查(cha)風(feng)機(ji)(ji)是否有(you)(you)異常(chang)現(xian)象(xiang),確認無異常(chang)現(xian)象(xiang)再開機(ji)(ji)運轉(zhuan)。
3. 速(su)(su)(su)(su)度調(diao)試(shi)。 雙速(su)(su)(su)(su)風(feng)機(ji)試(shi)車時(shi),應先啟動低速(su)(su)(su)(su),并檢(jian)查(cha)旋(xuan)轉方向是否正確;起(qi)動高速(su)(su)(su)(su)時(shi)**待風(feng)機(ji)靜止(zhi)后再起(qi),以防(fang)高速(su)(su)(su)(su)反(fan)向旋(xuan)轉,引起(qi)開關跳閘及(ji)電(dian)(dian)(dian)機(ji)受損(sun)。風(feng)機(ji)達到正常運(yun)速(su)(su)(su)(su)時(shi),應檢(jian)測風(feng)機(ji)各相輸(shu)入電(dian)(dian)(dian)源(yuan)是否正常,風(feng)機(ji)的運(yun)行(xing)電(dian)(dian)(dian)流(liu)(liu)(liu)不能超過其(qi)(qi)額定(ding)(ding)電(dian)(dian)(dian)流(liu)(liu)(liu),若運(yun)行(xing)電(dian)(dian)(dian)流(liu)(liu)(liu)超過其(qi)(qi)額定(ding)(ding)電(dian)(dian)(dian)流(liu)(liu)(liu),應檢(jian)查(cha)供(gong)給風(feng)機(ji)的電(dian)(dian)(dian)壓是否正常。
