蕪湖調(diào)速電機(jī)故障該如何檢修

調(diào)速電機(jī)故障該如何檢修

調(diào)速電機(jī)常用于許多的生產(chǎn)機(jī)械中，在許多企業(yè)的應(yīng)用都非常的廣泛，那么對(duì)于調(diào)速電機(jī)故障的情況該如何檢修呢?下面小編就結(jié)合武漢調(diào)速電機(jī)修理，給大家簡(jiǎn)析一下調(diào)速電機(jī)的故障如何檢修。

　　主傳動(dòng)電機(jī)運(yùn)轉(zhuǎn)不正常，滑差電機(jī)在運(yùn)轉(zhuǎn)過(guò)程中會(huì)劇烈振動(dòng)，引起軸承發(fā)熱，檢查電機(jī)的軸承是否嚴(yán)重缺乏潤(rùn)滑油脂，造成軸承嚴(yán)重磨損，電動(dòng)機(jī)的運(yùn)轉(zhuǎn)性能下降。更換已損壞的軸承，并加注好潤(rùn)滑油脂。

　　主機(jī)轉(zhuǎn)速周期性下降，主要是因?yàn)闄C(jī)械部分發(fā)生了故障所引起，膠輥的任何一端軸承發(fā)生了故障，都可能使主機(jī)的轉(zhuǎn)速周期性地下峰，嚴(yán)重時(shí)主機(jī)動(dòng)彈會(huì)更加挫折，所以更換軸承才行，并且主機(jī)各滾筒的軸承及其潤(rùn)滑部位故障都會(huì)影響轉(zhuǎn)速。

　　調(diào)速電機(jī)升速后，機(jī)速又逐漸下降以至停機(jī)出現(xiàn)這種情況，需要觀(guān)察調(diào)速電機(jī)電氣柜里的電流表指針的變化。檢查主電機(jī)回路的有關(guān)接線(xiàn)元件，及主電機(jī)的交流接觸器，熱繼電器等過(guò)載保護(hù)裝置的接線(xiàn)部位是否松動(dòng)，這種情況下，緊固接線(xiàn)螺釘，去除燒壞了的導(dǎo)線(xiàn)氧化物層，更換損壞嚴(yán)重的接線(xiàn)端子。
