一、振動電機電路連接故障排除。

　　振動盤廠家的三(san)相(xiang)(xiang)(xiang)電(dian)(dian)(dian)壓(ya)不(bu)(bu)(bu)平(ping)衡(heng)主要表現為(wei):(1)變壓(ya)器(qi)三(san)相(xiang)(xiang)(xiang)繞組有一相(xiang)(xiang)(xiang)異常，傳輸(shu)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)不(bu)(bu)(bu)對稱。(2)輸(shu)電(dian)(dian)(dian)線(xian)(xian)路長(chang)，導線(xian)(xian)截面尺寸不(bu)(bu)(bu)均(jun)勻(yun)，阻抗壓(ya)降不(bu)(bu)(bu)同，造成(cheng)各相(xiang)(xiang)(xiang)電(dian)(dian)(dian)壓(ya)不(bu)(bu)(bu)平(ping)衡(heng)。(3)電(dian)(dian)(dian)力、照明混合共(gong)用，其中(zhong)單相(xiang)(xiang)(xiang)負(fu)荷較多。比如家用電(dian)(dian)(dian)器(qi)、電(dian)(dian)(dian)爐、電(dian)(dian)(dian)焊機(ji)等(deng)。都過(guo)于集(ji)中(zhong)在一相(xiang)(xiang)(xiang)或兩相(xiang)(xiang)(xiang)，導致各相(xiang)(xiang)(xiang)電(dian)(dian)(dian)力負(fu)荷分布不(bu)(bu)(bu)均(jun)，供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)流不(bu)(bu)(bu)平(ping)衡(heng)。過(guo)載電(dian)(dian)(dian)機(ji)處于過(guo)載運行狀態(tai)，特(te)別是啟(qi)動(dong)時(shi)(shi)，電(dian)(dian)(dian)機(ji)定子(zi)(zi)和轉子(zi)(zi)電(dian)(dian)(dian)流增大(da)，產生熱量(liang)。時(shi)(shi)間稍(shao)長(chang)，振(zhen)動(dong)電(dian)(dian)(dian)機(ji)容易出現繞組電(dian)(dian)(dian)流不(bu)(bu)(bu)平(ping)衡(heng)。

　　二、振動電機過載(zai)問題調查。

　　振動盤廠家的(de)(de)振動電(dian)(dian)(dian)(dian)機(ji)中的(de)(de)異(yi)物摩(mo)擦影響電(dian)(dian)(dian)(dian)機(ji)的(de)(de)正常(chang)運(yun)行。聯軸(zhou)器(qi)零件歪斜(xie)，導(dao)(dao)致(zhi)(zhi)電(dian)(dian)(dian)(dian)機(ji)主軸(zhou)錯位。潤滑油干燥或缺失導(dao)(dao)致(zhi)(zhi)軸(zhou)承磨損電(dian)(dian)(dian)(dian)壓過(guo)高或過(guo)低，增加損耗。負載匹配不當，電(dian)(dian)(dian)(dian)機(ji)額定(ding)(ding)(ding)功(gong)率(lv)小于(yu)實際負載。電(dian)(dian)(dian)(dian)機(ji)地腳螺栓(shuan)或部件固定(ding)(ding)(ding)螺栓(shuan)松(song)動，導(dao)(dao)致(zhi)(zhi)電(dian)(dian)(dian)(dian)機(ji)或部件移位。定(ding)(ding)(ding)子(zi)(zi)和(he)轉子(zi)(zi)組(zu)故(gu)障(zhang)、匝間(jian)短(duan)(duan)路(lu)、局部接地、開(kai)路(lu)等。，會導(dao)(dao)致(zhi)(zhi)定(ding)(ding)(ding)子(zi)(zi)繞(rao)(rao)(rao)組(zu)中的(de)(de)一個或兩個電(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)大，從而嚴重(zhong)不平衡三(san)相電(dian)(dian)(dian)(dian)流(liu)(liu)。定(ding)(ding)(ding)子(zi)(zi)和(he)轉子(zi)(zi)繞(rao)(rao)(rao)組(zu)故(gu)障(zhang)的(de)(de)特(te)點(dian)是(shi)內孔有灰塵、雜物和(he)硬傷口(kou)，導(dao)(dao)致(zhi)(zhi)匝間(jian)短(duan)(duan)路(lu)。定(ding)(ding)(ding)子(zi)(zi)繞(rao)(rao)(rao)組(zu)的(de)(de)一相開(kai)路(lu)。定(ding)(ding)(ding)子(zi)(zi)繞(rao)(rao)(rao)組(zu)潮濕，有泄漏電(dian)(dian)(dian)(dian)流(liu)(liu)。軸(zhou)承和(he)轉子(zi)(zi)損壞變形，轉子(zi)(zi)和(he)定(ding)(ding)(ding)子(zi)(zi)繞(rao)(rao)(rao)組(zu)相互摩(mo)擦。鼠籠(long)式(shi)轉子(zi)(zi)繞(rao)(rao)(rao)組(zu)斷裂焊接，導(dao)(dao)致(zhi)(zhi)電(dian)(dian)(dian)(dian)流(liu)(liu)不穩(wen)定(ding)(ding)(ding)。

　　三、振(zhen)動(dong)電機在使用中操作(zuo)不當。

　　振動盤廠家的振(zhen)動(dong)電機(ji)安裝人(ren)員將相線(xian)和(he)零線(xian)反向連接(jie)。進線(xian)與(yu)接(jie)線(xian)盒(he)碰撞，造成(cheng)泄漏電流(liu)。開關、觸點和(he)接(jie)頭的松動(dong)和(he)氧化連接(jie)會導(dao)(dao)致(zhi)缺相。頻繁啟(qi)動(dong)，啟(qi)動(dong)時間(jian)過長或過短，導(dao)(dao)致(zhi)熔斷器斷相。長期使用，缺乏(fa)維護(hu)，使電機(ji)老化，局部(bu)絕緣退化。
