style="text-indent:25px">船用三相異步電動(dòng)機(jī)常見(jiàn)故障的檢查及維修方法——轉(zhuǎn)子故障：轉(zhuǎn)子故障可以分為兩類，一類是轉(zhuǎn)子繞組的故障，一類是轉(zhuǎn)子本身的故障。造成轉(zhuǎn)子故障的主要原因是轉(zhuǎn)子的制作工藝存在一定的缺陷，從而導(dǎo)致轉(zhuǎn)子的質(zhì)量不合格或者轉(zhuǎn)子在負(fù)荷的作用下本身結(jié)構(gòu)鏈接松動(dòng)，進(jìn)而使支架、鐵芯等部件松動(dòng)和開(kāi)裂。轉(zhuǎn)子的不平衡通常由其匝間的斷條、短路以及轉(zhuǎn)子零部件的松動(dòng)及脫落、轉(zhuǎn)子端環(huán)移位或者轉(zhuǎn)子安裝未校正造成。這些異常一旦發(fā)生，電機(jī)就會(huì)產(chǎn)生異常振動(dòng)和噪聲。如果是安裝未校正而導(dǎo)致的轉(zhuǎn)子不平衡，可以采用在其不平衡的一端配重的方法進(jìn)行修正。此外，當(dāng)出現(xiàn)電流擺動(dòng)及三相電流不平衡的現(xiàn)象時(shí)，較大的可能是由于轉(zhuǎn)子繞組的絕緣過(guò)熱，江蘇船舶發(fā)電機(jī)銷售，江蘇船舶發(fā)電機(jī)銷售、損傷和繞組間的污垢積聚而導(dǎo)致的轉(zhuǎn)子繞組的匝間短路。當(dāng)出現(xiàn)電機(jī)啟動(dòng)困難且電機(jī)電流擺動(dòng)時(shí)，其原因可能是轉(zhuǎn)子設(shè)計(jì)和制造的缺陷，也有可能是電機(jī)長(zhǎng)期過(guò)載，焊接不良而導(dǎo)致的轉(zhuǎn)子繞組斷路。若電機(jī)反復(fù)正反轉(zhuǎn)啟動(dòng)，或者長(zhǎng)期工作在重負(fù)荷下，船用電機(jī)很可能會(huì)發(fā)生斷條。在這種情況下，故障發(fā)生表現(xiàn)為電機(jī)在斷條運(yùn)行時(shí)出現(xiàn)周期性的振動(dòng)以及噪聲，江蘇船舶發(fā)電機(jī)銷售。發(fā)電機(jī)附帶的隨機(jī)配件一定要檢查，很多配件都是廠家原裝的才合適，自己配的不一定合適！江蘇船舶發(fā)電機(jī)銷售</p><div
