24、布將其全部揩干凈，檢查軸瓦合金面是 否有不正常的情況，必須清除任何嵌入軸瓦合金的硬質顆粒，軸承座底部 金屬顆粒和污物必須徹底干凈。5. 2 軸承的軸向調整5. 2. 1 電機的軸向安裝基準必須是電機的磁力中心線，出廠前，制造廠磁力中心線的位置已調整， 應按照電機磁中心位置批示牌的數(shù)值安裝電機。5. 2. 2 軸瓦和軸的單邊調整間隙為 6mm，允許軸的最大調整量為 12mm。空試電機開始時， 轉子來回游動， 最后穩(wěn)定在磁中心的位置。5. 3 供油系統(tǒng)的安裝：供油系 統(tǒng)的安裝應按照通用的供油系統(tǒng)安裝原則，應具有壓力表、溫度表、 流量計等輔助儀表5. 4 電機與主機連接完成后，帶負載 試驗之前，應將

25、 軸承座上蓋四個緊固螺栓松開， 退出銷釘， 輕微盤車， 讓球形軸瓦自動， 然后重新緊固。5. 5 帶油池加熱器的電機, 如果電機使用在北方的冬季, 在開機前 1 小時, 必須打開加熱器, 并時刻注意油池內的油溫, 確保油溫不超過 50 .5. 6 對自潤滑軸承的電機，加注潤滑油后的首次起動或電機停機超過 12 小時再次啟動前須對電機進行盤車，盤車轉數(shù)為 20 轉以上，使油環(huán)為軸瓦提供足夠的潤滑油，確保電機的安全啟動。5. 7 起動前檢查5. 7.1 自潤滑軸承，應檢查是否注油及油位，油環(huán)安裝是否正確。外循環(huán)注油應檢查供油系統(tǒng)是否工作正常。5. 7. 2 軸承上所有螺栓是否緊固。5. 7. 3

26、軸承測溫是否安裝正確， 工作正常。5. 7. 4 軸承座上方的觀察窗有無破損。5. 8 起動中的檢查。5. 8.1 軸承溫度應平穩(wěn)地升至恒定的工作溫度，如果溫度不穩(wěn)定，高于軸承所允許溫度應停機檢查。5. 8.2 不漏油性滑動軸承底腔，各連接孔處應不漏油。 自潤滑軸承漏油會破壞工作油面， 嚴重影響軸承的使用。5 Installation andStarting5. 1 Cleaning before installationTheprinciple is cleanliness during thefinal assembly connectingwithsleeve bearings is b
