1.　風機答應全壓(ya)(ya)(ya)起(qi)(qi)動(dong)或降(jiang)壓(ya)(ya)(ya)起(qi)(qi)動(dong)，但應留意，全壓(ya)(ya)(ya)起(qi)(qi)動(dong)時(shi)的電(dian)(dian)流約為5~7倍的額定(ding)電(dian)(dian)流，降(jiang)壓(ya)(ya)(ya)起(qi)(qi)動(dong)轉距與電(dian)(dian)流平方(fang)成正比(bi)，當(dang)電(dian)(dian)網(wang)容量不足時(shi)，應采用降(jiang)壓(ya)(ya)(ya)起(qi)(qi)動(dong)。（當(dang)功率大于11KW時(shi)，宜(yi)采用降(jiang)壓(ya)(ya)(ya)起(qi)(qi)動(dong)。） 

　　2.　風機(ji)在(zai)試車時(shi)，應(ying)(ying)當真(zhen)閱讀產(chan)品(pin)仿(fang)單，檢查接線(xian)方法是(shi)(shi)否同(tong)接線(xian)圖(tu)相符；應(ying)(ying)當真(zhen)檢查供應(ying)(ying)風機(ji)電(dian)(dian)(dian)源(yuan)的工作電(dian)(dian)(dian)壓是(shi)(shi)否符合要求，電(dian)(dian)(dian)源(yuan)是(shi)(shi)否缺(que)相或同(tong)相位，所配(pei)電(dian)(dian)(dian)器元件(jian)的容量是(shi)(shi)否符合要求。 

　　3.　試車(che)時(shi)人數不(bu)少于兩人，一人控制電(dian)源，一人觀(guan)察(cha)風(feng)機(ji)運(yun)(yun)轉(zhuan)情況，發現(xian)(xian)(xian)異常(chang)現(xian)(xian)(xian)象(xiang)立(li)刻(ke)停機(ji)檢查(cha)(cha)；首先檢查(cha)(cha)旋轉(zhuan)方(fang)向是(shi)否準確；風(feng)機(ji)開始(shi)運(yun)(yun)轉(zhuan)后，應立(li)刻(ke)檢查(cha)(cha)運(yun)(yun)轉(zhuan)電(dian)流(liu)是(shi)否平衡、電(dian)流(liu)是(shi)否超過額定電(dian)流(liu)；若不(bu)有正常(chang)現(xian)(xian)(xian)象(xiang)，應停機(ji)檢查(cha)(cha)。運(yun)(yun)轉(zhuan)五分鐘后，停機(ji)檢查(cha)(cha)風(feng)機(ji)是(shi)否有異常(chang)現(xian)(xian)(xian)象(xiang)，確認無異常(chang)現(xian)(xian)(xian)象(xiang)再開機(ji)運(yun)(yun)轉(zhuan)。 

　　4.雙速(su)(su)風機(ji)(ji)試車時(shi)，應先起(qi)(qi)動(dong)低速(su)(su)，并檢查(cha)旋轉(zhuan)方向(xiang)是(shi)否準確；起(qi)(qi)動(dong)高速(su)(su)成時(shi)必(bi)需(xu)待風機(ji)(ji)靜(jing)止后再起(qi)(qi)動(dong)，以防(fang)高速(su)(su)反向(xiang)旋轉(zhuan)，引(yin)起(qi)(qi)開關(guan)跳閘及電機(ji)(ji)受(shou)損。 

　　5.風機(ji)達到正(zheng)常(chang)(chang)轉速時，應(ying)檢(jian)(jian)測風機(ji)輸入電(dian)流(liu)是否正(zheng)常(chang)(chang)，風機(ji)的(de)運行(xing)電(dian)流(liu)不能超(chao)過其(qi)額定電(dian)流(liu)。若運行(xing)電(dian)流(liu)超(chao)過其(qi)額定電(dian)流(liu)，應(ying)檢(jian)(jian)查供應(ying)風機(ji)的(de)電(dian)壓是否正(zheng)常(chang)(chang)。 

　　6.風機所需電(dian)(dian)機(ji)功率是指(zhi)在一定(ding)(ding)工況(kuang)(kuang)下，對離心風(feng)(feng)機(ji)和風(feng)(feng)機(ji)箱，進風(feng)(feng)口全開時所需功率較(jiao)大(da)。若進風(feng)(feng)口全開進行運(yun)(yun)(yun)轉(zhuan)(zhuan)，則電(dian)(dian)機(ji)有損壞(huai)的可能。風(feng)(feng)機(ji)試車(che)時最好將(jiang)風(feng)(feng)機(ji)入口或(huo)出口管路上(shang)的閥門(men)封閉，運(yun)(yun)(yun)轉(zhuan)(zhuan)后(hou)將(jiang)閥門(men)徐徐開啟，達(da)到所需工況(kuang)(kuang)為止，并留(liu)意風(feng)(feng)機(ji)的運(yun)(yun)(yun)轉(zhuan)(zhuan)電(dian)(dian)流是否超(chao)過額(e)定(ding)(ding)電(dian)(dian)流。
