玻璃鋼離心風機廣泛用于工(gong)廠、礦(kuang)井、隧道、冷(leng)卻(que)塔、車(che)輛、船舶和建(jian)筑物的通(tong)風(feng)、排塵和冷(leng)卻(que)。玻(bo)璃鋼離心(xin)風(feng)機(ji)的調試方法有哪些?
1、玻(bo)璃鋼離(li)心風機允許全(quan)壓(ya)起動(dong)(dong)或降壓(ya)電(dian)(dian)動(dong)(dong),但(dan)應注(zhu)意,全(quan)壓(ya)起動(dong)(dong)時的電(dian)(dian)流約為(wei)5-7倍的額定電(dian)(dian)流,降壓(ya)起動(dong)(dong)轉矩與(yu)電(dian)(dian)壓(ya)平方成正(zheng)比,當電(dian)(dian)網容(rong)量不足時,應采用降壓(ya)起動(dong)(dong)。
2、玻(bo)璃鋼(gang)離心風(feng)機在試車(che)時,應認真(zhen)閱讀產品(pin)說明書,檢查接(jie)線方法是(shi)(shi)(shi)否同(tong)接(jie)線圖相符;應認真(zhen)檢查供給風(feng)機電(dian)源(yuan)的工作電(dian)壓是(shi)(shi)(shi)不是(shi)(shi)(shi)符合(he)要(yao)求(qiu),電(dian)源(yuan)是(shi)(shi)(shi)否缺相或同(tong)相位(wei),所(suo)配電(dian)器(qi)元件的容量(liang)是(shi)(shi)(shi)否符合(he)要(yao)求(qiu)。
3、試車時人數(shu)不少(shao)于兩人,一人控制電(dian)(dian)源(yuan),一人觀察風(feng)機運(yun)轉(zhuan)情況,發(fa)現(xian)(xian)異常現(xian)(xian)象(xiang)(xiang)(xiang)立即停機檢(jian)查;首(shou)先(xian)檢(jian)查旋轉(zhuan)方向是否(fou)(fou)(fou)正(zheng)確(que);玻璃鋼離心風(feng)機開始運(yun)轉(zhuan)后(hou),應立即檢(jian)查各相運(yun)轉(zhuan)電(dian)(dian)流(liu)是否(fou)(fou)(fou)平衡、電(dian)(dian)流(liu)是否(fou)(fou)(fou)超過(guo)額定電(dian)(dian)流(liu);若(ruo)有不正(zheng)常現(xian)(xian)象(xiang)(xiang)(xiang),應停機檢(jian)查。運(yun)轉(zhuan)五分鐘后(hou),停機檢(jian)查風(feng)機是否(fou)(fou)(fou)有異常現(xian)(xian)象(xiang)(xiang)(xiang),確(que)認無異常現(xian)(xian)象(xiang)(xiang)(xiang)再開機運(yun)轉(zhuan)。
4、雙(shuang)速玻(bo)璃鋼離心風機試(shi)車(che)時(shi)(shi),應先起(qi)動低速,檢查(cha)旋轉方向是否(fou)正確;起(qi)動高速時(shi)(shi)要待風機靜止后再(zai)啟(qi)動,以防高速反(fan)向旋轉,引起(qi)開關跳閘及電機受損(sun)。
5、玻璃鋼離心風機(ji)達到(dao)正(zheng)(zheng)常轉速時,應測量風機(ji)輸(shu)入電(dian)流(liu)(liu)(liu)是否正(zheng)(zheng)常,玻璃鋼離心風機(ji)的運行(xing)電(dian)流(liu)(liu)(liu)不能(neng)超(chao)過其額定電(dian)流(liu)(liu)(liu)。若(ruo)運行(xing)電(dian)流(liu)(liu)(liu)超(chao)過其額定電(dian)流(liu)(liu)(liu),應檢(jian)查供給的電(dian)壓是否正(zheng)(zheng)常。
6、玻璃鋼離心風機所(suo)需(xu)電(dian)(dian)機(ji)(ji)(ji)功率(lv)是指在一定工(gong)況下,對玻璃鋼離心風(feng)(feng)(feng)機(ji)(ji)(ji)和風(feng)(feng)(feng)機(ji)(ji)(ji)箱,進(jin)風(feng)(feng)(feng)口(kou)全開(kai)時所(suo)需(xu)功率(lv)較(jiao)大。若進(jin)風(feng)(feng)(feng)口(kou)全開(kai)進(jin)行(xing)運轉,則電(dian)(dian)機(ji)(ji)(ji)有損壞的危險。風(feng)(feng)(feng)機(ji)(ji)(ji)試車(che)時最好將(jiang)風(feng)(feng)(feng)機(ji)(ji)(ji)進(jin)口(kou)或(huo)出(chu)口(kou)管道上的閥(fa)門(men)關閉(bi),運轉后將(jiang)閥(fa)門(men)漸漸開(kai)啟,達到所(suo)需(xu)工(gong)況為止,并注(zhu)意風(feng)(feng)(feng)機(ji)(ji)(ji)的運轉電(dian)(dian)流是否超(chao)過額定電(dian)(dian)流。
