耐酸堿襯氟自吸泵流量和揚(yáng)程的穩(wěn)定性襯氟自吸泵是耐酸堿液輸送常用的泵，自吸泵是否能穩(wěn)定工作是由它的性能決定的，性能用工作參數(shù)表示。流量、揚(yáng)程、功率、效率等參數(shù)相互之間是有一定關(guān)系的，如果將參數(shù)關(guān)系用曲線形式來(lái)表示，就是水泵性能曲線。一、自吸泵運(yùn)行中，如何使自吸泵流量揚(yáng)程穩(wěn)定工作？A.自吸穩(wěn)定方法：1、自吸泵的吸水管道吸水口安裝了底閥，底閥不能正常吸起，建議選用合適的底閥。2、輸送的液體含有雜物顆粒，由于管道或者泵體遭遇了堵塞現(xiàn)象從而使其自吸泵揚(yáng)程達(dá)不到，輸送污水建議選用自吸排污泵更合適。3、輸送的液體腐蝕性嚴(yán)重，自吸泵的葉輪遭遇了嚴(yán)重的腐蝕建議選用耐腐蝕的自吸泵產(chǎn)品例如不銹鋼自吸泵或者氟塑料自吸泵，或者使用時(shí)間長(zhǎng)后自吸泵葉輪遭遇了磨損葉輪與泵蓋之間的間隙太大也是自吸泵揚(yáng)程達(dá)不到的原因建議更換新的自吸泵葉輪，北京襯氟離心泵定制。4、用戶購(gòu)買(mǎi)的自吸泵頭與自配的電機(jī)有錯(cuò)，比如:實(shí)際需要2900r/min的電機(jī)而用戶配成了1450r/min的電機(jī)。5，北京襯氟離心泵定制、由于進(jìn)口管道太長(zhǎng)超出了自吸泵的自吸能力，如果進(jìn)口管道淹沒(méi)在水里的管道在1米以上，建議縮短水里的管道長(zhǎng)度減少自吸距離，北京襯氟離心泵定制。四氟泵哪家專(zhuān)業(yè)，上海原孚泵業(yè)值得信賴(lài)，有需求的不要錯(cuò)過(guò)哦！北京襯氟離心泵定制</p><div

汽蝕的危害汽蝕會(huì)影響離心泵的正常運(yùn)行，引發(fā)許多嚴(yán)重后果。汽蝕致使泵產(chǎn)生噪音與振動(dòng)當(dāng)發(fā)生汽蝕時(shí)，高頻的液體相互撞擊會(huì)產(chǎn)生各種噪音，嚴(yán)重時(shí)泵內(nèi)會(huì)發(fā)出噼噼啪啪的聲，同時(shí)誘發(fā)泵機(jī)組的振動(dòng)，而泵機(jī)組的振動(dòng)又會(huì)加速氣泡的產(chǎn)生與破裂。當(dāng)液擊的頻率與泵機(jī)組的固有頻率相同時(shí)，就會(huì)發(fā)生強(qiáng)烈的汽蝕共振，使振幅迅速增大，此時(shí)若要保護(hù)離心泵不會(huì)發(fā)生更大的破壞，就必須立即停車(chē)檢查。汽蝕制約了離心泵的發(fā)展隨著科技不斷進(jìn)步，現(xiàn)代化工業(yè)要求離心泵要向大流量和高揚(yáng)程發(fā)展，這就需要提高介質(zhì)的流速，根據(jù)流體力學(xué)，液體流速越高，入口壓力損失越大，更加容易產(chǎn)生汽蝕。因此，提高泵抗汽蝕性能，研究汽蝕機(jī)理，是離心泵發(fā)展中的重要研究課題。江西襯氟磁力泵生產(chǎn)襯氟離心泵哪家服務(wù)好，上海原孚泵業(yè)為您服務(wù)！歡迎您的光臨！</p><div

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(qiáng)度和疲勞強(qiáng)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(guò)隨后的處理工藝（冷作硬化、熱處理等）獲得足夠的硬度和強(qiáng)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(guò)程中的焊接工藝要求。對(duì)于地溝敷設(shè)的熱力管網(wǎng)，當(dāng)補(bǔ)償器所處管道地勢(shì)較低時(shí)，雨水或事故性污水會(huì)浸泡波紋管，應(yīng)考慮選用耐蝕性更強(qiáng)的材料，如鐵鎳合金、高鎳合金等。由于此類(lèi)材料價(jià)格較高，在制造波紋管時(shí)，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(jì)由波紋管補(bǔ)償器的失效類(lèi)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(guò)低的疲勞壽命將會(huì)導(dǎo)致金屬波紋管穩(wěn)定性及耐蝕性能下降。

葉輪常見(jiàn)的問(wèn)題及處理方法A、腐蝕1.故障表現(xiàn)：選材不當(dāng)。2.處理方法：更換新葉輪，耐腐蝕磨損材料；葉輪耐蝕層的涂鍍；葉輪耐蝕層的噴涂。B、汽蝕1.故障表現(xiàn)：設(shè)計(jì)方案不當(dāng)；安裝位置過(guò)高；選材不當(dāng)?shù)取?.處理方法：降低安裝位置；改變更能夠抗汽蝕的材質(zhì)；重新設(shè)計(jì)泵型等。C、口環(huán)抱死1.故障表現(xiàn)：設(shè)計(jì)間隙過(guò)?。磺昂罂诃h(huán)的硬度差小于50HBW；口環(huán)間隙有固體顆粒；口環(huán)變形等。2.處理方法：增大設(shè)計(jì)間隙；更換口環(huán)材質(zhì)；檢查工藝介質(zhì)；更換新口環(huán)等。D、斷裂1.故障表現(xiàn)：由于汽蝕、腐蝕、磨蝕引起的；鑄件質(zhì)量較差導(dǎo)致；水錘導(dǎo)致的。2.處理方法：更換新葉輪。E、鑄造缺陷1.故障表現(xiàn)：流道夾雜；多肉；不光滑；沙眼；裂紋；縮松等。2.處理方法：可根據(jù)實(shí)際情況進(jìn)行磨削、補(bǔ)焊等方法，如果問(wèn)題嚴(yán)重，需打廢重鑄。F、磨蝕1.故障表現(xiàn)：由灰鑄鐵材料鑄造的流程泵葉輪在5年時(shí)間內(nèi)被含有少量水泥泡沫的水磨損的情況，磨蝕問(wèn)題更多的是設(shè)計(jì)方選材不當(dāng)或泵型選擇不當(dāng)造成的，或者是工藝介質(zhì)被污染導(dǎo)致的。2.處理方法：更改葉輪材質(zhì)；更改設(shè)計(jì)方案，改變泵型；檢查工藝介質(zhì)。襯氟離心泵哪家服務(wù)好，上海原孚泵業(yè)為您服務(wù)！期待您的來(lái)電！</p><div
