對于軸承雜音，應在電動機運行中經(jīng)常聽說。聽說方法是：將螺絲刀一端頂住軸承安裝部位，另一端貼近耳朵，便可聽到軸承運轉(zhuǎn)聲。若軸承運轉(zhuǎn)正常，其聲音為連續(xù)而細小的"沙沙"聲，不會有忽高忽低的變化及金屬摩擦聲。若出現(xiàn)以下幾種聲音則為不正?，F(xiàn)象。(1)軸承運轉(zhuǎn)時有"吱吱"聲，這是金屬摩擦聲，一般為軸承缺油所致，應拆開軸承加注適量潤滑脂。(2)若出現(xiàn)"唧哩"聲，這是滾珠轉(zhuǎn)動時發(fā)出的聲音，一般為潤滑脂干涸或缺油引起，可加注適量油脂。(3)若出現(xiàn)"喀喀"聲或"嘎吱"聲，則為軸承內(nèi)滾珠不規(guī)則運動而產(chǎn)生的聲音，這是軸承內(nèi)滾珠損壞或電動機長期不用，潤滑脂干涸所致。3.若傳動機構(gòu)和被傳動機構(gòu)發(fā)出連續(xù)而非忽高忽低的聲音，可分以下幾種情況處理。(1)周期性"啪啪"聲，為皮帶接頭不平滑引起。(2)周期性"咚咚"聲，為聯(lián)軸器或皮帶輪與軸間松動以及鍵或鍵槽磨損引起。(3)不均勻的碰撞聲，為風葉碰撞風扇罩引起。氟塑料磁力泵定制氟塑料離心泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，期待您的光臨！</p><div

離心泵檢修，檢修標準按設備制造廠要求執(zhí)行，無要求的按本標準執(zhí)行。5、密封機械密封a.壓蓋與軸套的直徑間隙為，壓蓋與密封腔間的墊片厚度為1~2mm。b.密封壓蓋與靜環(huán)密封圈接觸部位的粗糙度為。c.安裝機械密封部位的軸或軸套，表面不得有銹斑、裂紋等缺陷，粗糙度。d.凡軸向止推采用滾動軸承的泵，其滾動軸承外圈的軸向間隙應留有。e.滾動軸承拆裝時，采用熱裝的溫度不超過120℃，嚴禁直接用火焰加熱，推薦采用高頻感應加熱器。f.滾動軸承的滾動體與滾道表面應無腐蝕、坑疤與斑點，接觸平滑無雜音，保持架完好。e.彈簧壓縮后的工作長度應符合設計要求。f.機械密封并圈彈簧的旋向應與泵軸的旋轉(zhuǎn)方向相反。g.壓蓋螺栓應均勻上緊，防止壓蓋端面傾斜。h.靜環(huán)裝入壓蓋后，應檢查確認靜環(huán)無偏斜。填料密封a.間隔環(huán)與軸套的直徑間隙一般為。b.間隙環(huán)與填料箱的直徑間隙為。c.填料壓蓋與軸套的直徑間隙為。d.填料壓蓋與填料箱的直徑間隙為。e.填料底套與軸套的直徑間隙為。f.填料環(huán)的外徑應小于填料函孔徑，內(nèi)徑大于軸徑。切口角度一般與軸向成45°。g.安裝時，相鄰兩道填料的切口至少應錯開90°。

化工泵電動機維修技巧——看觀察電動機運行過程中有無異常，其主要表現(xiàn)為以下幾種情況。1.定子繞組短路時，可能會看到電動機冒煙。2.電動機嚴重過載或缺相運行時，轉(zhuǎn)速會變慢且有較沉重的"嗡嗡"聲。3.電動機正常運行，但突然停止時，會看到接線松脫處冒火花;保險絲熔斷或某部件被卡住等現(xiàn)象。4.若電動機劇烈振動，則可能是傳動裝置被卡住或電動機固定不良、底腳螺栓松動等。5.若電動機內(nèi)接觸點和連接處有變色、燒痕和煙跡等，則說明可能有局部過熱、導體連接處接觸不良或繞組燒毀等。三、電動機維修技巧——聞通過聞電動機的氣味也能判斷及預防故障。若發(fā)現(xiàn)有特殊的油漆味，說明電動機內(nèi)部溫度過高;若發(fā)現(xiàn)有很重的糊味或焦臭味，則可能是絕緣層被擊穿或繞組已燒毀。襯氟離心泵哪家服務好，上海原孚泵業(yè)為您服務！</p><div

平衡盤結(jié)構(gòu)存在的缺陷：(1)當泵轉(zhuǎn)子以較低速度啟動時，泵中流體產(chǎn)生的推力較小，無法將平衡盤推離平衡座，導致工作時二者接觸，產(chǎn)生研磨，造成磨損，達到一定限度后需進行更換，降低平衡盤使用壽命。(2)平衡盤軸向間隙極小，使得其應用范圍受限，不適用于泵體內(nèi)液體含沙、泵干轉(zhuǎn)或泵內(nèi)液體接近氣化等工況。(3)由于平衡盤依靠平衡管泄露泵內(nèi)液體，使其前后產(chǎn)生壓差來平衡軸向力，泄露會造成泵的效率降低。平衡鼓在離心壓縮機軸向力平衡領域應用較為普遍，平衡鼓不存在軸向間隙，帶壓液體經(jīng)平衡鼓徑向間隙進入平衡腔，構(gòu)成高壓，于其后的空腔內(nèi)壁上設置平衡管與泵入口相通，使腔內(nèi)壓力始終大于或等于入口壓力，從而達到平衡軸向力的目的。采用平衡鼓結(jié)構(gòu)平衡軸向力，平衡鼓結(jié)構(gòu)動靜部間的間隙為制造時制定，無法自動調(diào)整平衡力大小，因而，需要在外部安裝止推軸承以平衡多余的平衡力，其優(yōu)點在于，動靜部無接觸，無磨損，因而使用壽命較長。四氟泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，歡迎您的光臨！內(nèi)蒙古襯氟磁力泵零售</p><p

氣蝕的危害汽蝕會使離心泵的性能下降離心泵是通過葉輪的旋轉(zhuǎn)將能量傳遞給介質(zhì)，轉(zhuǎn)化為介質(zhì)的壓力能，但汽蝕會對葉輪和液體之間的能量傳遞造成嚴重干擾。當汽蝕發(fā)生時會在介質(zhì)中產(chǎn)生大量的氣泡，堵塞了葉輪流道，并在局部產(chǎn)生漩渦，增大流動損失，使泵的流量、揚程和效率均有所下降，嚴重時還會導致斷流，使離心泵無法正常工作。從圖1汽蝕嚴重時離心泵的性能曲線上來看，在汽蝕比較嚴重時，各項性能指標發(fā)生陡降。汽蝕會損壞過流部件在離心泵的過流部件中葉輪是受汽蝕影響大的零件，當發(fā)生汽蝕時，金屬材料表面會逐漸產(chǎn)生許多小麻點，繼而麻點不斷發(fā)展擴大呈蜂窩狀、溝槽狀，嚴重時就會形成穿孔，甚至造成葉輪的斷裂，嚴重影響泵的使用壽命。內(nèi)蒙古襯氟磁力泵零售</p><p
