</p><p> 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。4、用戶購(gòu)買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、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。襯氟離心泵推薦，上海原孚泵業(yè)值得信賴，相信您的選擇，值得信賴。</p><div

汽蝕的產(chǎn)生原理汽蝕是一種液體動(dòng)力學(xué)現(xiàn)象，發(fā)生的根本原因在于液體在流動(dòng)過(guò)程中出現(xiàn)了局部壓力降，形成了低壓區(qū)。根據(jù)物理學(xué)知識(shí)可以知道，對(duì)于某種液相介質(zhì)，在一定溫度下對(duì)應(yīng)著一定的飽和蒸汽壓Pv，當(dāng)介質(zhì)的壓力小于Pv時(shí)就會(huì)發(fā)生汽化。離心泵運(yùn)轉(zhuǎn)時(shí)，介質(zhì)進(jìn)入泵吸入口后，在葉輪沒有對(duì)介質(zhì)做功前，壓力是逐漸降低的，當(dāng)壓力降低到該處相應(yīng)溫度下的飽和蒸汽壓時(shí)，介質(zhì)就會(huì)沸騰汽化，使原來(lái)流動(dòng)的介質(zhì)出現(xiàn)大量的氣泡，氣泡中包含著輸送介質(zhì)的蒸汽以及原來(lái)溶解在介質(zhì)中而逸出的空氣。當(dāng)氣泡隨同液流從低壓區(qū)流向高壓區(qū)時(shí)，由于轉(zhuǎn)動(dòng)的葉輪對(duì)介質(zhì)做功，介質(zhì)壓力迅速上升，當(dāng)壓力大于該處相應(yīng)溫度下的飽和蒸汽壓Pv時(shí)，氣泡又會(huì)重新凝結(jié)成為液相，瞬間形成大量的空穴，而周圍的液相介質(zhì)以高速?zèng)_向空穴相互撞擊，使得空穴處的局部壓力陡增。這種液擊是一種**度、高頻率的沖擊，其壓力可達(dá)數(shù)百個(gè)大氣壓以上，水擊頻率高達(dá)25000次/秒，材料壁面上因受到如此高頻率、高壓力的重復(fù)載荷作用而逐漸產(chǎn)生疲勞破壞。襯氟磁力泵選哪家，上海原孚泵業(yè)為您服務(wù)！詳細(xì)可訪問(wèn)我司官網(wǎng)查看！遼寧襯氟離心泵定制</p><p
