正壓送風機的應用非常廣泛

正壓(ya)(ya)送(song)(song)風(feng)機(ji)的應(ying)用(yong)非常廣泛(fan)，其(qi)工藝(yi)較為(wei)簡單(dan)，結構緊湊，同(tong)時(shi)(shi)安裝(zhuang)方便，相較于其(qi)他類(lei)型散熱(re)風(feng)扇成本可觀(guan)。那么在我們(men)應(ying)用(yong)正壓(ya)(ya)送(song)(song)風(feng)機(ji)時(shi)(shi)應(ying)該要注意些什么呢？以(yi)不至(zhi)于導致軸流(liu)風(feng)扇壽命縮短或罷(ba)工。正壓(ya)(ya)送(song)(song)風(feng)機(ji)達到(dao)正常轉速時(shi)(shi)，應(ying)檢測5.5KW正壓(ya)(ya)送(song)(song)風(feng)機(ji)電流(liu)是(shi)否(fou)正常，5.5KW正壓(ya)(ya)送(song)(song)風(feng)機(ji)的運行電流(liu)不能超過其(qi)額定電流(liu)。

若運(yun)行(xing)電(dian)(dian)(dian)流超過(guo)其額(e)定電(dian)(dian)(dian)流，應(ying)(ying)檢(jian)查供給風機(ji)(ji)的電(dian)(dian)(dian)壓(ya)是否正常。正壓(ya)送風機(ji)(ji)裝機(ji)(ji)時，一(yi)人(ren)控(kong)制電(dian)(dian)(dian)源，一(yi)人(ren)觀察風機(ji)(ji)運(yun)轉(zhuan)情況，發現(xian)(xian)異常現(xian)(xian)象(xiang)立即停機(ji)(ji)檢(jian)查；首先檢(jian)查旋轉(zhuan)標的目(mu)的是否準確；5.5KW正壓(ya)送風機(ji)(ji)起頭運(yun)轉(zhuan)后，應(ying)(ying)立即檢(jian)查運(yun)轉(zhuan)電(dian)(dian)(dian)流是否平衡(heng)、電(dian)(dian)(dian)流是否超過(guo)額(e)定電(dian)(dian)(dian)流；若不(bu)有正常現(xian)(xian)象(xiang)，應(ying)(ying)停機(ji)(ji)檢(jian)查。

運轉(zhuan)五分鐘(zhong)后，停(ting)機(ji)檢查5.5KW正(zheng)壓(ya)(ya)(ya)送(song)(song)風機(ji)是否有異常現象，確認無異常現象再(zai)開(kai)機(ji)運轉(zhuan)。正(zheng)壓(ya)(ya)(ya)送(song)(song)風機(ji)啟(qi)動時允許降(jiang)壓(ya)(ya)(ya)啟(qi)動或全(quan)壓(ya)(ya)(ya)啟(qi)動，在(zai)全(quan)壓(ya)(ya)(ya)啟(qi)動時正(zheng)壓(ya)(ya)(ya)送(song)(song)風機(ji)的電流約為5~7倍的額定電流，降(jiang)壓(ya)(ya)(ya)啟(qi)動時與電流平方成正(zheng)比，所以當電網容量不足時，應采(cai)用降(jiang)壓(ya)(ya)(ya)啟(qi)動。
