三(san)相(xiang)異步電(dian)動(dong)機過載(zai)后的(de)現象如下：

三相異步電動機發出異常的振動或(huo)聲(sheng)音。

三(san)相異步(bu)電動(dong)機轉速(su)下降，嚴重時(shi)會失速(su)。

、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)低。當(dang)(dang)(dang)三相(xiang)(xiang)異步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機滿載(zai)或啟動時(shi)，如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)較小（例如(ru)正(zheng)常(chang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)90％），則電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流將相(xiang)(xiang)應增加110％的(de)比例。這是(shi)因為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機功率(lv)是(shi)恒(heng)定(ding)的(de)，當(dang)(dang)(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)下降且軸(zhou)功率(lv)恒(heng)定(ding)時(shi)，三相(xiang)(xiang)異步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機只能通(tong)過增加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流來(lai)確保功率(lv)輸出。通(tong)常(chang)出現這種情況有(you)兩個原因。 　　首先，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)本身很低，此(ci)時(shi)，需要(yao)調整變壓(ya)(ya)(ya)(ya)器(qi)的(de)分接(jie)開(kai)關，分接(jie)開(kai)關分為兩種類型：有(you)載(zai)調壓(ya)(ya)(ya)(ya)和空載(zai)調壓(ya)(ya)(ya)(ya)。顧(gu)名思義(yi)，有(you)載(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)調節(jie)意味(wei)著沒(mei)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)故障，并且可以(yi)直接(jie)調節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)。對于空載(zai)調壓(ya)(ya)(ya)(ya)，必須(xu)在調壓(ya)(ya)(ya)(ya)之(zhi)前(qian)關閉(bi)變壓(ya)(ya)(ya)(ya)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。 　　其次，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)之(zhi)間的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜太長，我(wo)們知道一般電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜是(shi)低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)銅(tong)芯，但是(shi)較小并不意味(wei)著沒(mei)有(you)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜距離越(yue)(yue)長，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)越(yue)(yue)小。并且電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機串聯連(lian)接(jie)，并且電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)必須(xu)串聯分配，當(dang)(dang)(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)較大(da)時(shi)，分壓(ya)(ya)(ya)(ya)也較大(da)，因此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動機上使用的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)自(zi)然較小。為了解(jie)決這個問(wen)題，通(tong)常(chang)增加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)截面積或改用附(fu)近的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。

、三相(xiang)異(yi)步電(dian)(dian)(dian)動(dong)機選型不當。對于(yu)啟(qi)動(dong)時間長的(de)設備，例如：球(qiu)磨機等(deng)。必須使(shi)用(yong)啟(qi)動(dong)電(dian)(dian)(dian)流小，啟(qi)動(dong)轉矩大(da)的(de)深槽型雙鼠籠(long)式(shi)轉子的(de)電(dian)(dian)(dian)動(dong)機或(huo)直接繞組式(shi)電(dian)(dian)(dian)動(dong)機。在上述(shu)情況下，普通電(dian)(dian)(dian)動(dong)機很(hen)容(rong)易燒毀電(dian)(dian)(dian)動(dong)機。

在許(xu)多高(gao)(gao)壓(ya)防(fang)爆電(dian)機(ji)(ji)中，滑(hua)動軸承(cheng)的(de)(de)使用越(yue)來(lai)越(yue)多，主要(yao)是在重要(yao)的(de)(de)生(sheng)產(chan)(chan)部門(men)和(he)(he)(he)產(chan)(chan)品加工領(ling)域。這(zhe)也是因(yin)為(wei)滑(hua)動軸承(cheng)的(de)(de)使用可以(yi)(yi)提高(gao)(gao)高(gao)(gao)壓(ya)防(fang)爆電(dian)機(ji)(ji)的(de)(de)效率(lv)和(he)(he)(he)運(yun)行(xing)安(an)全(quan)性。但是，當安(an)裝和(he)(he)(he)使用進行(xing)匹配時，一些粗(cu)心和(he)(he)(he)小的(de)(de)技術問題會導致(zhi)軸承(cheng)漏油的(de)(de)問題，這(zhe)種問題的(de)(de)出(chu)現(xian)會降低高(gao)(gao)壓(ya)防(fang)爆電(dian)機(ji)(ji)的(de)(de)使用效率(lv)和(he)(he)(he)安(an)全(quan)隱患。要(yao)想(xiang)改(gai)善這(zhe)種狀(zhuang)況，必須高(gao)(gao)度重視高(gao)(gao)壓(ya)防(fang)爆電(dian)機(ji)(ji)的(de)(de)內部設計和(he)(he)(he)軸承(cheng)的(de)(de)生(sheng)產(chan)(chan)加工，以(yi)(yi)便更(geng)好地保護它，更(geng)好地體(ti)現(xian)高(gao)(gao)壓(ya)防(fang)爆電(dian)機(ji)(ji)的(de)(de)性能和(he)(he)(he)安(an)全(quan)性。

一(yi)、高壓防爆電機軸承的(de)基本結構

滑(hua)動(dong)軸(zhou)(zhou)承(cheng)(cheng)由軸(zhou)(zhou)瓦和軸(zhou)(zhou)承(cheng)(cheng)座(zuo)組成，這也(ye)提高(gao)了(le)軸(zhou)(zhou)承(cheng)(cheng)的(de)(de)穩定(ding)性(說明：是(shi)穩定(ding)的(de)(de)；無變化)，以(yi)及(ji)密封(feng)圈、油環、軸(zhou)(zhou)瓦等輔助零件，較好的(de)(de)高(gao)壓(ya)防爆(bao)電(dian)機(ji)是(shi)帶軸(zhou)(zhou)承(cheng)(cheng)測溫(wen)的(de)(de)零件，如(ru)果滑(hua)動(dong)軸(zhou)(zhou)承(cheng)(cheng)上涂有(you)潤滑(hua)油，摩擦(ca)會大大減小，有(you)利于(yu)高(gao)壓(ya)防爆(bao)電(dian)機(ji)的(de)(de)安全運行。高(gao)壓(ya)電(dian)機(ji)是(shi)指額定(ding)電(dian)壓(ya)在1000伏(fu)以(yi)上的(de)(de)電(dian)機(ji)。經(jing)常使用(yong)6000伏(fu)和10000伏(fu)電(dian)壓(ya)，由于(yu)國外電(dian)網的(de)(de)不同，也(ye)有(you)3300伏(fu)和6600伏(fu)的(de)(de)電(dian)壓(ya)水平。高(gao)壓(ya)電(dian)機(ji)具有(you)功率大、抗沖擊能力強的(de)(de)優點；缺點是(shi)慣性大，啟動(dong)和制動(dong)困難。高(gao)壓(ya)防爆(bao)電(dian)機(ji)連續(xu)運行或過載運行時(shi)，應及(ji)時(shi)加潤滑(hua)油，以(yi)便更(geng)好地(di)使用(yong)。

油(you)泵電動機(ji)油(you)漆烘(hong)干的五種方法(fa)

1、生石灰干燥法

將油泵電動機放入(ru)密(mi)封箱內(nei)，在(zai)箱內(nei)撒上(shang)生(sheng)石灰，利用生(sheng)石灰強大的吸(xi)濕能力(li)干燥(zao)油泵電動機。該方法安全省力(li)，但(dan)干燥(zao)時間長且相對耗時。

2、燈泡干燥法

可(ke)以通過(guo)使用紅外線燈泡或(huo)普通燈泡直接將光照射到油(you)泵(beng)電動機(ji)的定子繞(rao)組(zu)上并(bing)改(gai)變燈泡功率(lv)來(lai)改(gai)變溫度(du)。也可(ke)以通過(guo)測量(liang)鐵(tie)芯溫度(du)來(lai)控制繞(rao)組(zu)溫度(du)，隨時測量(liang)油(you)泵(beng)電動機(ji)的絕緣電阻，滿足要求后停止干燥(zao)。

3、電流干燥方法

油泵(beng)電(dian)(dian)動(dong)機的定子繞(rao)(rao)組(zu)按照一定的連(lian)(lian)接方式(shi)連(lian)(lian)接，然后向線圈中引入電(dian)(dian)流(liu)，利用繞(rao)(rao)組(zu)的銅(tong)耗(hao)熱(re)對繞(rao)(rao)組(zu)進行(xing)烘干。主要連(lian)(lian)接方式(shi)有串(chuan)聯加(jia)(jia)熱(re)型、星形加(jia)(jia)熱(re)型、三(san)角形加(jia)(jia)熱(re)型等。無論哪種方式(shi)，分配(pei)給各相(xiang)繞(rao)(rao)組(zu)的烘烤電(dian)(dian)流(liu)應(ying)控(kong)制在額定電(dian)(dian)流(liu)的60%~80%，通電(dian)(dian)6~8小時(shi)，繞(rao)(rao)組(zu)溫度應(ying)達到70℃~80℃。

4、鐵損干燥法

絕緣線纏繞在(zai)油(you)(you)泵(beng)電(dian)(dian)動機的定子(zi)鐵芯上，交(jiao)流電(dian)(dian)源(yuan)接(jie)通(tong)，產(chan)生(sheng)交(jiao)變磁通(tong)，在(zai)定子(zi)鐵芯中形成(cheng)渦流，加熱定子(zi)鐵芯，使油(you)(you)泵(beng)電(dian)(dian)動機干燥。

5、熱(re)風(feng)循環干燥方(fang)法

電加熱(re)空氣循環干燥箱也(ye)稱為烘箱。烘箱是由鐵皮制(zhi)成的(de)(de)。電熱(re)絲安(an)裝在箱體底部和兩側的(de)(de)側壁上。加熱(re)元件(jian)的(de)(de)外部覆蓋有鐵皮。一(yi)方(fang)面(mian)，熱(re)量可以通過鐵片傳導，箱內溫度(du)更均勻(yun)。另一(yi)方(fang)面(mian)，防止(zhi)油(you)漆直接滴落到加熱(re)元件(jian)上，造成明火并燒毀油(you)泵電動機。通電期(qi)間，應使用(yong)酒精(jing)溫度(du)計(ji)(ji)監控烘箱溫度(du)，酒精(jing)溫度(du)計(ji)(ji)不(bu)得超過規定(ding)的(de)(de)允許值。溫度(du)計(ji)(ji)不(bu)得用(yong)于(yu)監測烤箱的(de)(de)溫度(du)，以防溫度(du)計(ji)(ji)意外損(sun)壞。滴入(ru)油(you)泵電動機的(de)(de)定(ding)子繞(rao)組，導致(zhi)繞(rao)組短路。此外，用(yong)于(yu)排出濕氣和溶劑蒸汽(qi)的(de)(de)通氣孔留在烤箱的(de)(de)頂部。
