      電機保養
      專業電機保養維修中心電機保養流程:清洗定轉子--更換碳刷或其他零部件--真空F級壓力浸漆--烘干--校動平衡。   1、使用環境應經常保持干燥,電動機表面應保持清潔,進風口不應受塵土、纖維等阻礙。   2、當電動機的熱保護連續發生動作時應查明故障來自電動機還是超負荷或保護裝置整定值太低,消除故障后,方可投入運行。   3、應保證電動機在運行過程中良好的潤滑。一般的電動機運行5000小時左右,即應補充或更換潤滑脂,運行中發現軸承過熱或潤滑變質時,液壓及時換潤滑脂。更換潤滑脂時,應清除舊的潤滑油薏⒂釁油洗凈軸承及軸承蓋的油槽,然后將ZL-3鋰基脂填充軸承內外圈之間的空腔的1/2(對2極)及2/3(對4、6、8極)。   4、當軸承的壽命終了時,電動機運行的振動及噪聲將明顯增大,檢查軸承的徑向游隙達到下列值時,即應更換軸承。   5、拆卸電動機時,從軸伸端或非伸端蕹鱟子都可以。如果沒有必要卸下風扇,還是從非軸伸端取出轉子較為便利,從定子中抽出轉子時,應防止損壞定子繞組或絕緣。   6、更換繞組時必須記下原繞組的形式,尺寸及匝數,線規等,當失落了這些數據時,應向制造廠索取,隨意更改原設計繞組,常常使電動機某項或幾項性薅窕,甚至于無法使用。

      Professional motor maintenance repair center maintenance process: cleaning of motor stator and rotor - replace carbon brush or other parts of vacuum pressure impregnation - F - drying - balancing school. 1, the use of the environment should be kept dry, motor surface should be kept clean, air inlet to dust, fiber and other obstacles. In 2, when the motor thermal protection continuously happen when, should find fault from motor or overload protection device setting value or too low, eliminate malfunction, can be put into operation. The 3, should ensure the motor in the operation process of the good lubrication. General motors run for about 5000 hours, shall supplement or replace grease, discovered in moving bearing overheating or lubrication modification, hydraulic timely for lubricating grease. Replacing the grease, should remove the old oil, and gasoline to clean the bearing and the bearing cover of the oil tank, and then the ZL-3 lithium grease filled bearing inner and outer ring cavity between 1 / 2 ( 2 pole) and 2 / 3 ( 4, 6, 8 poles ). In 4, when the bearing life end, motor running vibration and noise will increase obviously, check the radial clearance of the bearings to the following values, namely, replace the bearing. In 5, removing the motor, the shaft extension end or the extension end of rotor can be removed. If there is no need to remove the fan, or from a shaft extension end take the rotor is convenient, from out of the rotor in the stator, the stator winding insulation should prevent damage or. In 6, replacing the windings must take down the original winding form, size and number of turns, gauge, when lost these data, to the factory to obtain, arbitrarily change the original design the motor winding, often one or several performance deterioration, and even can not be used.
