金(jin)力特(te)為(wei)您介紹YBF3風機(ji)用電機(ji)的故障(zhang)現象和原因分析：

故障(zhang)現象：電動(dong)機起(qi)動(dong)時(shi)保險絲熔(rong)斷。原因：①定子(zi)(zi)線圈一相反(fan)接。②定子(zi)(zi)線圈短路或接地。③軸承(cheng)損壞。④傳動(dong)皮帶太(tai)緊(jin)。⑤被(bei)帶動(dong)機械(xie)卡住。⑥起(qi)動(dong)時(shi)誤操作。

故障(zhang)現(xian)象：電(dian)(dian)動機起(qi)動后轉速較低。原因：①電(dian)(dian)源電(dian)(dian)壓過低。②將三角(jiao)形接線的(de)(de)電(dian)(dian)動機接成星形。③定子線圈短(duan)路。④轉子的(de)(de)短(duan)路環、籠條斷裂或開(kai)焊(han)。⑤電(dian)(dian)動機過負荷。

風機(ji)防爆電機(ji)啟動時應注意以(yi)下事(shi)項：

1、合閘起動前(qian)，應觀看電動機及(ji)機械上或附(fu)近(jin)是否有異物，以免發生人(ren)身及(ji)設備事(shi)故。

2、防(fang)爆電(dian)(dian)機(ji)接通電(dian)(dian)源后(hou)，如(ru)果發現(xian)電(dian)(dian)動(dong)(dong)機(ji)不能起動(dong)(dong)或(huo)起動(dong)(dong)時轉速很低(di)以及聲音不正常(chang)等現(xian)象，應立即(ji)切斷電(dian)(dian)源，對高壓異步防(fang)爆振(zhen)動(dong)(dong)電(dian)(dian)機(ji)應進(jin)行試起動(dong)(dong)，YBF3風機(ji)用電(dian)(dian)機(ji)生產(chan)廠(chang)家，察看其轉動(dong)(dong)方向是否正確。

3、起動多臺防爆(bao)電(dian)機時，應(ying)按容量從大到小一臺一臺起動，YBF3風機用電(dian)機生產商，不能同(tong)時起動，以免(mian)起動電(dian)流過大使斷路器跳閘。

4、對(dui)于籠(long)型(xing)防爆電機的(de)星(xing)形——三角形起(qi)動(dong)(dong)或自(zi)耦(ou)減壓(ya)起(qi)動(dong)(dong)，若是手動(dong)(dong)延(yan)1時控(kong)制的(de)起(qi)動(dong)(dong)設備，應(ying)注意(yi)起(qi)動(dong)(dong)操(cao)作順(shun)序和(he)控(kong)制好延(yan)1時長短(duan)。對(dui)于繞線型(xing)電動(dong)(dong)機的(de)起(qi)動(dong)(dong)。更應(ying)注意(yi)起(qi)動(dong)(dong)操(cao)作程序和(he)觀察起(qi)動(dong)(dong)過(guo)程是否(fou)(fou)正常。否(fou)(fou)則(ze)兩種電動(dong)(dong)機都達不到降(jiang)1壓(ya)起(qi)動(dong)(dong)的(de)目(mu)的(de)。

5、防(fang)(fang)爆電(dian)(dian)機(ji)應(ying)(ying)避(bi)免頻繁起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)或盡量減少起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)次(ci)(ci)數，防(fang)(fang)止因起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)頻繁而使(shi)防(fang)(fang)爆振動(dong)(dong)(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)發熱(re)(re)(re)，影響電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)的使(shi)用(yong)壽命。對于(yu)小型電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)，在(zai)冷態時(shi)不得超過(guo)3~5次(ci)(ci)，在(zai)長(chang)期(qi)工作后的熱(re)(re)(re)態下(xia)，停機(ji)不久再起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)時(shi)，連續起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)不得超過(guo)2～3次(ci)(ci)。對于(yu)中型防(fang)(fang)爆電(dian)(dian)機(ji)，在(zai)冷態時(shi)連續起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)不應(ying)(ying)超過(guo)兩(liang)次(ci)(ci)，熱(re)(re)(re)態下(xia)只(zhi)允許1次(ci)(ci)起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)，以免電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)過(guo)熱(re)(re)(re)，影響使(shi)用(yong)壽命。對起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)時(shi)間(jian)不超過(guo)2~3秒(miao)的電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)，可多起(qi)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)次(ci)(ci)。

6、多(duo)臺起(qi)(qi)(qi)(qi)動(dong)(dong)機(ji)(ji)應避免(mian)同(tong)時起(qi)(qi)(qi)(qi)動(dong)(dong)，應從容量大的(de)(de)到小的(de)(de)逐臺起(qi)(qi)(qi)(qi)動(dong)(dong)，以免(mian)線路上(shang)總(zong)的(de)(de)起(qi)(qi)(qi)(qi)動(dong)(dong)電(dian)流過大，電(dian)壓下降(jiang)太多(duo)，影響(xiang)所有防爆電(dian)機(ji)(ji)的(de)(de)正(zheng)常起(qi)(qi)(qi)(qi)動(dong)(dong)，YBF3風機(ji)(ji)用(yong)電(dian)機(ji)(ji)報(bao)價(jia)，甚至使開關設備跳閘(zha)。

軸流防爆電機配(pei)件(jian)為何要(yao)進行(xing)浸漆：

1、防爆電(dian)機(ji)的(de)調速馬達要(yao)浸漆是提高(gao)繞組的(de)電(dian)氣性能(neng)和機(ji)械強(qiang)度。

2、提高繞組絕緣的(de)喝血(xue)穩定(ding)性，使(shi)其(qi)具有防霉、防電暈、防油(you)污等能力。

3、提高繞組絕緣的耐潮性能。

4、減緩繞(rao)組(zu)絕(jue)緣(yuan)的老化速度，湖北YBF3風機用電機，提高導(dao)熱(re)性能，增加散熱(re)效果。
