檢查防(fang)(fang)(fang)爆(bao)振(zhen)(zhen)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)接線端(duan)子螺栓(shuan)(shuan)及底座固(gu)定(ding)螺栓(shuan)(shuan)是(shi)否松動(dong)(dong)(dong)(dong)，YBZJ粉塵防(fang)(fang)(fang)爆(bao)振(zhen)(zhen)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)實力推薦，是(shi)否有(you)不(bu)正(zheng)常(chang)雜(za)音、振(zhen)(zhen)動(dong)(dong)(dong)(dong)及特(te)(te)殊(shu)氣(qi)味(wei)。螺栓(shuan)(shuan)松動(dong)(dong)(dong)(dong)或振(zhen)(zhen)動(dong)(dong)(dong)(dong)，不(bu)僅會產生噪音，還(huan)要減(jian)少防(fang)(fang)(fang)爆(bao)振(zhen)(zhen)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)使用(yong)壽命。檢查防(fang)(fang)(fang)爆(bao)振(zhen)(zhen)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)偏(pian)心塊是(shi)否轉動(dong)(dong)(dong)(dong)異常(chang)，是(shi)否有(you)不(bu)正(zheng)常(chang)雜(za)音、振(zhen)(zhen)動(dong)(dong)(dong)(dong)及特(te)(te)殊(shu)氣(qi)味(wei)。起重冶金(jin)用(yong)防(fang)(fang)(fang)爆(bao)電(dian)(dian)機(ji)及加氫裝置配套用(yong)增安型無刷勵(li)磁同步電(dian)(dian)機(ji)等。此外，還(huan)可按額定(ding)電(dian)(dian)壓、效率等技術指標來分(fen)。

檢查軸封(feng)(feng)（例如V型(xing)密(mi)封(feng)(feng)圈(quan)或骨架(jia)密(mi)封(feng)(feng)圈(quan)）的(de)(de)狀況，YBZJ粉塵(chen)(chen)(chen)防爆(bao)(bao)振動(dong)電(dian)機實(shi)力推薦(jian)(jian)，必要時應更換(huan)；通過建聽(ting)防爆(bao)(bao)振動(dong)電(dian)機噪音(yin)異常(chang)、振動(dong)測量、溫度檢測、監控用(yong)油量或SPM軸承檢測等，四(si)川粉塵(chen)(chen)(chen)防爆(bao)(bao)振動(dong)電(dian)機實(shi)力推薦(jian)(jian)，判斷軸承的(de)(de)運行狀況。發現有磨損跡象時應拆(chai)卸電(dian)機并(bing)檢查零部(bu)件，YBZJ粉塵(chen)(chen)(chen)防爆(bao)(bao)振動(dong)電(dian)機實(shi)力推薦(jian)(jian)，必要時進行更換(huan)。更換(huan)軸承時應同(tong)(tong)時用(yong)與原配相(xiang)同(tong)(tong)質量和性能的(de)(de)密(mi)封(feng)(feng)圈(quan)更換(huan)軸用(yong)密(mi)封(feng)(feng)圈(quan)。正常(chang)情況下，更換(huan)的(de)(de)軸承型(xing)號(hao)須與原配相(xiang)同(tong)(tong)。

防(fang)爆振動電(dian)機堵轉故(gu)障(zhang)的主要(yao)原(yuan)(yuan)(yuan)因：原(yuan)(yuan)(yuan)因一：可能(neng)有一相(xiang)斷路(lu)。解決(jue)(jue)方法(fa)：檢(jian)查(cha)電(dian)源(yuan)線是否有開路(lu)。原(yuan)(yuan)(yuan)因二：使用工(gong)況不當。解決(jue)(jue)方法(fa)：更換(huan)型號或基(ji)座號。原(yuan)(yuan)(yuan)因三：防(fang)爆振動電(dian)機出(chu)現(xian)過(guo)載。解決(jue)(jue)方法(fa)：減輕防(fang)爆電(dian)機負(fu)載。原(yuan)(yuan)(yuan)因四：電(dian)壓(ya)低。解決(jue)(jue)方法(fa)：確(que)保(bao)按(an)銘牌電(dian)壓(ya)供(gong)電(dian)，檢(jian)查(cha)接(jie)線。原(yuan)(yuan)(yuan)因五：出(chu)現(xian)開路(lu)。解決(jue)(jue)方法(fa)：檢(jian)查(cha)保(bao)險絲是否熔(rong)斷，檢(jian)查(cha)過(guo)載繼電(dian)器、定子(zi)和按(an)鈕。
