1、軸流風機允許全壓(ya)起動(dong)或降壓(ya)電(dian)(dian)(dian)動(dong),但應注(zhu)意,全壓(ya)起動(dong)時的電(dian)(dian)(dian)流約為5-7倍(bei)的額定電(dian)(dian)(dian)流,降壓(ya)起動(dong)轉矩與電(dian)(dian)(dian)壓(ya)平方成正(zheng)比,當電(dian)(dian)(dian)網容量不足時,應采(cai)用降壓(ya)起動(dong)。
2、雙速軸流風機試車時,應(ying)先起動低速,檢查旋轉(zhuan)方向是否正確;起動高速時待風機靜止后再啟動,以防高速反向旋轉(zhuan),引起開關跳閘及電機受損。
3、軸流風機在試車時(shi),應認(ren)真閱讀(du)產品說明(ming)書,檢(jian)查接(jie)線(xian)方(fang)法是(shi)否同(tong)接(jie)線(xian)圖相(xiang)(xiang)符(fu);應認(ren)真檢(jian)查供給(gei)風機電(dian)源(yuan)的工作電(dian)壓是(shi)不是(shi)符(fu)合(he)要(yao)求(qiu),電(dian)源(yuan)是(shi)否缺(que)相(xiang)(xiang)或同(tong)相(xiang)(xiang)位,所配電(dian)器元件的容量(liang)是(shi)否符(fu)合(he)要(yao)求(qiu)。
4、試車時人(ren) 數不(bu)少于兩人(ren),一人(ren)控制(zhi)電(dian)(dian)源,一人(ren)觀察風(feng)機(ji)(ji)(ji)運(yun)轉(zhuan)(zhuan)情況(kuang),發現(xian)(xian)異(yi)常(chang)現(xian)(xian)象(xiang)(xiang)立即停機(ji)(ji)(ji)檢(jian)(jian)(jian)查(cha)(cha);首先(xian)檢(jian)(jian)(jian)查(cha)(cha)旋轉(zhuan)(zhuan)方向是否(fou)正確;軸流(liu)風(feng)機(ji)(ji)(ji)開(kai)始運(yun)轉(zhuan)(zhuan)后(hou),應立即檢(jian)(jian)(jian)查(cha)(cha)各相運(yun)轉(zhuan)(zhuan)電(dian)(dian)流(liu) 是否(fou)平衡(heng)、電(dian)(dian)流(liu)是否(fou)超過額定電(dian)(dian)流(liu);若有不(bu)正常(chang)現(xian)(xian)象(xiang)(xiang),應停機(ji)(ji)(ji)檢(jian)(jian)(jian)查(cha)(cha)。運(yun)轉(zhuan)(zhuan)五分鐘后(hou),停機(ji)(ji)(ji)檢(jian)(jian)(jian)查(cha)(cha)風(feng)機(ji)(ji)(ji)是否(fou)有異(yi)常(chang)現(xian)(xian)象(xiang)(xiang),確認無異(yi)常(chang)現(xian)(xian)象(xiang)(xiang)再開(kai)機(ji)(ji)(ji)運(yun)轉(zhuan)(zhuan)。
5、軸流風機達(da)到正(zheng)(zheng)常轉(zhuan)速時,應(ying)測(ce)量風機(ji)輸入電(dian)(dian)流(liu)(liu)是(shi)(shi)否正(zheng)(zheng)常,軸流(liu)(liu)風機(ji)的運(yun)行電(dian)(dian)流(liu)(liu)不(bu)能超過(guo)其(qi)額定(ding)電(dian)(dian)流(liu)(liu)。若(ruo)運(yun)行電(dian)(dian)流(liu)(liu)超過(guo)其(qi)額定(ding)電(dian)(dian)流(liu)(liu),應(ying)檢查供給的電(dian)(dian)壓是(shi)(shi)否正(zheng)(zheng)常。
