營口低噪聲電機廠家
具(ju)有(you)良好(hao)的(de)(de)密封性(xing),用(yong)(yong)于(yu)一般(ban)場所的(de)(de)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)防護(hu)等級(ji)為IP44,用(yong)(yong)于(yu)冶(ye)(ye)金場所的(de)(de)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)防護(hu)等級(ji)為IP54。YZR系列為繞線轉子三(san)相異步(bu)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji),YZ系列為鼠籠轉子三(san)相異步(bu)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)。的(de)(de)絕(jue)緣等級(ji)分為F級(ji)和H級(ji)兩種。適用(yong)(yong)于(yu)驅動(dong)(dong)(dong)各(ge)種起(qi)重機(ji)(ji)械及冶(ye)(ye)輔助設備,具(ju)有(you)較高的(de)(de)過載(zai)能力和機(ji)(ji)械強度,特別適用(yong)(yong)于(yu)短時或斷續(xu)運轉,頻繁起(qi)動(dong)(dong)(dong)、制動(dong)(dong)(dong)及有(you)顯著振動(dong)(dong)(dong)及有(you)沖擊(ji)的(de)(de)設備。
還(huan)有(you)許多,當與其連接(jie)使(shi)用(yong)的(de)泵漏水(shui)時,通常都去加壓(ya)滅(mie)漏,有(you)經(jing)驗(yan)(yan)的(de)維修工在加、換盤根時,都會先(xian)用(yong)手盤轉(zhuan)一下,看(kan)轉(zhuan)動(dong)情況,均衡上緊壓(ya)蓋螺絲,再(zai)短時起、停兩三(san)次,看(kan)看(kan)工作電(dian)(dian)流(liu)等是否正常;而沒有(you)經(jing)驗(yan)(yan)的(de)新維修工,只知道上緊滅(mie)漏,不(bu)注意與之(zhi)相關的(de),結果導(dao)致電(dian)(dian)動(dong)機(ji)因堵轉(zhuan)起動(dong)電(dian)(dian)流(liu)太大,熱過載(zai)保護來不(bu)及動(dong)作而擊穿繞(rao)組燒(shao)壞。也應認真查驗(yan)(yan)和校正電(dian)(dian)動(dong)機(ji)與被驅動(dong)機(ji)械的(de)妯心線,確(que)保對中良好。
定(ding)子繞阻采用F級絕緣(yuan)材料,端(duan)部(bu)有可(ke)(ke)靠(kao)的(de)固定(ding)及捆(kun)扎,在(zai)制造過程中經過多(duo)次匝間(jian)脈沖電(dian)壓(ya)試驗及對地耐壓(ya)試驗,并采用真(zhen)空(kong)壓(ya)力(li)(li)浸漬無溶劑漆(qi)工(gong)藝處理(li),的(de)絕緣(yuan)性能(neng)優良可(ke)(ke)靠(kao),機械強度好,防(fang)潮能(neng)力(li)(li)強。繞線轉子采用F級絕緣(yuan)材料和真(zhen)空(kong)壓(ya)力(li)(li)浸漬無溶劑漆(qi)工(gong)藝處理(li),轉子焊頭和接線處全部(bu)有靠(kao)的(de)絕緣(yuan)。軸(zhou)承有滾(gun)動軸(zhou)承和滑(hua)動軸(zhou)承兩種(zhong)形式,按(an)照電(dian)機功率大小及轉速而定(ding),如電(dian)機具有較高的(de)防(fang)護等級時,軸(zhou)承的(de)防(fang)護等級也隨之提高。
電機由定子架、繞組及絕緣材料、轉子、兩端妯承及端蓋等組成,比較簡單。電動機故障的原因有:電源斷相、電壓或頻率不對;繞組短路、斷路、接地;電機內、外部臟,散熱不(bu)(bu)好,和自帶冷卻風(feng)扇壞(huai),通風(feng)不(bu)(bu)暢;與機械裝備不(bu)(bu)良;長(chang)期高負荷運(yun)行;環境溫度(du)高等等。電動機的損壞(huai),90%以上都(dou)是維修人員日(ri)常檢(jian)查不(bu)(bu)細,維護保養(yang)不(bu)(bu)足造成的,絕(jue)大多數(shu)故障都(dou)可釉預防和避免,減(jian)少(shao)公司備件和修理費用的損失。
