ABB-DI810
要想消除電動機(jī)振動，首先要查清產(chǎn)生振動的原因，只有找到振動的原因，才能采取有針對性的措施，消除電動機(jī)振動。電動機(jī)未停機(jī)之前，用測振表檢查各部振動情況，對于振動較大的部位按垂直水平軸向三個方向詳細(xì)測試振動數(shù)值，如果是地腳螺絲松動或軸承端蓋螺絲松動，則可直接緊固，緊固后在測其振動大小，觀察是否有消除或減輕，其次要檢查電源三相電壓是否平衡，三相熔絲是否有燒斷現(xiàn)象，電動機(jī)的單相運(yùn)行不僅可以引起振動，還會使電機(jī)的溫度迅速上升，觀察電流表指針是否來回?cái)[動，轉(zhuǎn)子斷條時就出現(xiàn)電流擺動現(xiàn)象，最后檢查電機(jī)三相電流是否平衡，發(fā)現(xiàn)問題及時與運(yùn)行人員聯(lián)系停止電機(jī)運(yùn)行，以免將電機(jī)燒損。如果對表面現(xiàn)象處理后，電機(jī)振動未解決，則繼續(xù)斷開電源，解開聯(lián)軸器，使電機(jī)與之相連的負(fù)載機(jī)械分離，單轉(zhuǎn)電機(jī)，如果電機(jī)本身不振動，則說明振源是聯(lián)軸器沒找正或負(fù)載機(jī)械引起的，如果電機(jī)振動，則說明電機(jī)本身有問題，另外還可以采取斷電法來區(qū)分是電氣原因，還是機(jī)械原因，當(dāng)停電瞬間，電動機(jī)馬上不振動或振動減輕，則說明是電氣原因，否則是機(jī)械故障。檢查氣隙是否均勻，如果測量值超標(biāo)，重新調(diào)整氣隙。檢查軸承，測量軸承間隙，如不合格更換新軸承，檢查鐵心變形和松動情況，松動的鐵心可用環(huán)氧樹脂膠粘接灌實(shí)，檢查轉(zhuǎn)軸，對彎曲的轉(zhuǎn)軸進(jìn)行補(bǔ)焊重新加工或直接直軸，然后對轉(zhuǎn)子做平衡試驗(yàn)。打風(fēng)機(jī)電機(jī)大修后試運(yùn)行期間，電機(jī)不僅振動大，而且軸瓦溫度超標(biāo)，連續(xù)處理幾天后，故障仍未解決。我班組人員在幫助處理時發(fā)現(xiàn)，電機(jī)氣隙非常大，瓦座水平也不合格，故障原因找到后，重新調(diào)整各部間隙后，電機(jī)試轉(zhuǎn)一次成功。
