屋頂風機調試工作怎么進行
屋頂風機允許全壓啟動或(huo)降壓啟動,但應(ying)注意,全壓啟動時(shi)電流是額定電流5~7倍(bei),降壓啟動轉(zhuan)距與電壓平(ping)方(fang)成正比,當電網(wang)容(rong)量不足時(shi),應(ying)采(cai)用(yong)降壓啟動。如(ru)功率大于11KW,則宜采(cai)用(yong)降壓啟動方(fang)式。屋頂(ding)屋頂(ding)風(feng)機廠家
二、試車時,人數不(bu)少于二人,一(yi)人控制電(dian)源,一(yi)人觀(guan)察屋頂(ding)風機運(yun)(yun)轉(zhuan),發現異常(chang)(chang)現象(xiang),立(li)即(ji)停(ting)機檢查;首先(xian)檢查旋轉(zhuan)方(fang)向是(shi)否(fou)正確;在(zai)屋頂(ding)風機運(yun)(yun)行過(guo)程(cheng)中(zhong),應(ying)檢查各相運(yun)(yun)行電(dian)流是(shi)否(fou)平衡(heng),電(dian)流是(shi)否(fou)超過(guo)額定電(dian)流;如有異常(chang)(chang)現象(xiang),應(ying)立(li)即(ji)停(ting)機檢查。運(yun)(yun)行5分鐘(zhong)后,停(ting)止運(yun)(yun)行,檢查屋頂(ding)風機是(shi)否(fou)有異常(chang)(chang)現象(xiang),確認(ren)無異常(chang)(chang)現象(xiang)后再啟動運(yun)(yun)行。
三(san)、雙速(su)屋頂風機(ji)試運轉時,應先(xian)啟(qi)動低速(su),并檢(jian)查旋(xuan)(xuan)轉方向(xiang)是否正確;在(zai)啟(qi)動高(gao)速(su)時,應待屋頂風機(ji)靜止(zhi)后再起動,以防高(gao)速(su)反向(xiang)旋(xuan)(xuan)轉,造成開關跳閘和電機(ji)損壞。
四、屋(wu)(wu)(wu)頂(ding)風(feng)機達到(dao)正常運轉速度時,應檢(jian)測屋(wu)(wu)(wu)頂(ding)風(feng)機各相輸入電(dian)源是否(fou)正常,屋(wu)(wu)(wu)頂(ding)風(feng)機的運行電(dian)流(liu)不得超(chao)過其額定電(dian)流(liu),如果超(chao)過了額定電(dian)流(liu),應檢(jian)查(cha)供屋(wu)(wu)(wu)頂(ding)風(feng)機電(dian)壓是否(fou)正常。屋(wu)(wu)(wu)頂(ding)屋(wu)(wu)(wu)頂(ding)風(feng)機報價
五.對于離心屋頂風機和屋頂(ding)風(feng)(feng)(feng)機(ji)(ji)(ji)箱,要求的(de)(de)電(dian)動(dong)機(ji)(ji)(ji)功(gong)率是(shi)指(zhi)在(zai)待定工(gong)況下,加上機(ji)(ji)(ji)械損失(shi)與其(qi)應(ying)有的(de)(de)備用(yong)容量相(xiang)比,不(bu)是(shi)在(zai)出(chu)風(feng)(feng)(feng)口(kou)完全打(da)開(kai)時(shi)所(suo)需(xu)要的(de)(de)功(gong)率,如果屋頂(ding)風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)出(chu)風(feng)(feng)(feng)口(kou)沒(mei)有連接(jie)管道或(huo)沒(mei)有外(wai)部(bu)阻力(li)進(jin)行空(kong)運轉,則電(dian)動(dong)機(ji)(ji)(ji)有燒毀的(de)(de)危(wei)險,為安(an)全起見(jian),應(ying)在(zai)屋頂(ding)風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)出(chu)風(feng)(feng)(feng)口(kou)或(huo)進(jin)口(kou)管路上加上閥(fa)門(men),啟(qi)動(dong)屋頂(ding)風(feng)(feng)(feng)機(ji)(ji)(ji)時(shi)關閉,運轉后將閥(fa)門(men)慢(man)慢(man)打(da)開(kai),直至(zhi)達到規定工(gong)況為止(zhi),并(bing)注意屋頂(ding)風(feng)(feng)(feng)機(ji)(ji)(ji)電(dian)流是(shi)否超過(guo)規定值(zhi)。
