style="text-align: center;"><img src="http://clirik.clirik.com.cn/uploads/image/2023/08-30/0edc59ac3a95fbb58ebc028f5c6ec54d.jpg" alt="3.jpg"/></p><p><br/>一、密封風(fēng)壓故障<br/>在磨粉機(jī)的內(nèi)部，磨輥密封是為了防止磨內(nèi)高濃度粉塵進(jìn)入磨輥腔內(nèi)，保護(hù)磨輥軸承不受損傷，通過(guò)密封機(jī)向磨輥腔內(nèi)鼓入高壓風(fēng)，在磨輥腔內(nèi)形成正壓，從而達(dá)到阻止粉塵進(jìn)入的目的。但是磨內(nèi)的工況十分復(fù)雜，懸浮狀態(tài)的粉塵濃度很高，在生產(chǎn)過(guò)程中常會(huì)出現(xiàn)以下情況：<br/>1、密封風(fēng)機(jī)風(fēng)壓低或密封風(fēng)機(jī)的濾網(wǎng)和濾布積灰堵塞，造成進(jìn)入磨粉機(jī)磨腔內(nèi)的密封風(fēng)量及風(fēng)壓降低；<br/>2、風(fēng)壓密封管道的法蘭及磨內(nèi)密封管道上關(guān)節(jié)軸承各連接點(diǎn)密封差而漏風(fēng)，致使進(jìn)入磨粉機(jī)磨輥腔內(nèi)的風(fēng)壓降低；<br/>3、在磨機(jī)投料運(yùn)行或停機(jī)狀態(tài)下磨內(nèi)拉風(fēng)不合理會(huì)在磨輥腔內(nèi)產(chǎn)生微負(fù)壓狀態(tài)；<br/>以上所提到的原因都有可能導(dǎo)致進(jìn)入磨輥腔內(nèi)的風(fēng)量和風(fēng)壓降低，容易使微顆粒物料進(jìn)入磨輥密封風(fēng)腔內(nèi)，損壞磨輥密封圈和油封，導(dǎo)致磨粉機(jī)生產(chǎn)中，磨輥漏油或軸承損傷的現(xiàn)象。<br/><br/>二、磨輥內(nèi)油位過(guò)高或過(guò)低<br/>在磨粉機(jī)的工作中，油位的高低有著嚴(yán)格且明確的規(guī)定，對(duì)于磨輥來(lái)說(shuō)，其回油管真空度決定了磨輥腔內(nèi)的油位，真空度壓力的調(diào)整直接關(guān)系到磨輥軸承的潤(rùn)滑狀態(tài)，油位過(guò)高或過(guò)低都會(huì)造成磨輥漏油或軸承損傷。<br/>鑒于磨輥潤(rùn)滑系統(tǒng)對(duì)磨粉機(jī)軸承的重要性，在正常生產(chǎn)中可通過(guò)簡(jiǎn)易方法快速診斷出磨輥軸承是否存在故障：<br/>方法一、現(xiàn)場(chǎng)觀察磨輥里油質(zhì)狀況，或通過(guò)檢測(cè)油樣中的金屬顆粒含量，判斷磨輥軸承是否損傷，如果油樣中金屬顆粒含量較多，說(shuō)明軸承已損傷嚴(yán)重。<br/>方法二、觀察磨輥回油溫度，如果某磨輥回油溫度升高，其他磨輥回油溫度正常，說(shuō)明該磨輥軸承有損傷。</p><p><strong><span
