化工耐酸堿離心泵被廣泛應(yīng)用于石化、冶金、水利、電力及核電等工業(yè)領(lǐng)域，在各種生產(chǎn)裝置中對液體介質(zhì)進行動力輸送，其性能可靠性對于裝置的正常運行有著非常重要的作用。汽蝕是離心泵運行中的一個重要現(xiàn)象，是影響離心泵運行可靠性和使用壽命比較常見的問題，同時也是影響其向大流量、高轉(zhuǎn)速方向發(fā)展的一個巨大的障礙，因此汽蝕成為目前泵類研究中的一個重要課題。當(dāng)發(fā)生汽蝕時，高頻的液體相互撞擊會產(chǎn)生各種噪音，嚴重時泵內(nèi)會發(fā)出噼噼啪啪的聲，同時誘發(fā)泵機組的振動，而泵機組的振動又會加速氣泡的產(chǎn)生與破裂，四川襯氟磁力泵生產(chǎn)。當(dāng)液擊的頻率與泵機組的固有頻率相同時，就會發(fā)生強烈的汽蝕共振，四川襯氟磁力泵生產(chǎn)，使振幅迅速增大，此時若要保護離心泵不會發(fā)生更大的破壞，就必須立即停車檢查，四川襯氟磁力泵生產(chǎn)。襯氟泵推薦，上海原孚泵業(yè)值得信賴，期待您的來電！四川襯氟磁力泵生產(chǎn)</p><div

<p> 氨水具有揮發(fā)性和刺激性，泵密封圈和滑片均采用特殊配方，耐磨蝕性、韌性、強度非常高，皖金泵閥泵殼的材料是高密度耐磨蝕的材料，有鋼襯氟，不銹鋼，氟合金等，加工后光潔度高，采用機械密封,與無軸封的磁力驅(qū)動泵，并采用填充聚四氟乙烯靜環(huán)代替石墨靜環(huán)，解決了氨水泵的泄漏問題，延長了泵的使用壽命，從而保證了氨液的不泄漏。氨水泵的特點就是密封性好，無泄漏，壓力高且運行穩(wěn)定。河南襯氟泵批發(fā)襯氟離心泵哪家服務(wù)好，上海原孚泵業(yè)為您服務(wù)！詳細可訪問我司官網(wǎng)查看！</p><div

對于軸承雜音，應(yīng)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(yīng)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(fēng)葉碰撞風(fēng)扇罩引起。

一般情況下，選用波紋管的材料應(yīng)滿足下列條件：（1）高彈性極限、抗拉強度和疲勞強度，保證波紋管正常工作。（2）良好的塑性，便于波紋管的加工成形，且能通過隨后的處理工藝（冷作硬化、熱處理等）獲得足夠的硬度和強度。（3）較好的耐腐蝕性能，滿足波紋管在不同環(huán)境下工作要求。（4）良好的焊接性能，滿足波紋管在制作過程中的焊接工藝要求。對于地溝敷設(shè)的熱力管網(wǎng)，當(dāng)補償器所處管道地勢較低時，雨水或事故性污水會浸泡波紋管，應(yīng)考慮選用耐蝕性更強的材料，如鐵鎳合金、高鎳合金等。由于此類材料價格較高，在制造波紋管時，可以考慮*在與腐蝕性介質(zhì)接觸的表面增加一層耐蝕合金。疲勞壽命設(shè)計由波紋管補償器的失效類型及原因分析可以看出，波紋管的平面穩(wěn)定性、周向穩(wěn)定性及耐腐蝕性能均與其位移量即疲勞壽命相關(guān)。過低的疲勞壽命將會導(dǎo)致金屬波紋管穩(wěn)定性及耐蝕性能下降。化工泵推薦，上海原孚泵業(yè)值得信賴，有需求的不要錯過哦！陜西化工泵制造</p><p

<p> b.波紋管輔助密封波紋管有輔助密封的功能。波紋管密封的特點就是摩擦副撓性安裝環(huán)的所有相對位移可以由彈性波紋管來補償，這就允許安裝摩擦副密封環(huán)有較大的偏差。不存在徑向接觸式輔助密封圈沿密封面滑移的問題。四川襯氟磁力泵生產(chǎn)</p><p
