一．產(chǎn)品描述：HP系列化工流程旋盤泵的結(jié)構(gòu)設(shè)計獨特，對輸送物料損傷小。由于HP系列化工流程旋盤泵轉(zhuǎn)子獨特的開放設(shè)計，HP系列化工流程旋盤泵可輸送固體性顆粒漿料（非吸水性固體），如：渣漿、砂漿、灰漿、污泥、水煤漿、尾礦渣漿等。HP系列化工流程旋盤泵能輸送含有氣體的物料。二，合川區(qū)化工泵專業(yè)制造.HP系列化工流程旋盤泵的應(yīng)用范圍和特點:許多應(yīng)用場合工況條件苛刻，如：介質(zhì)含有固體顆粒、粘度大、具有很強的磨蝕性、腐蝕性等對泵具有強烈的破壞性，并使得泵性能嚴重下降。HD系列化工流程旋盤泵能很好的輸送高粘度，合川區(qū)化工泵專業(yè)制造、高磨蝕性，合川區(qū)化工泵專業(yè)制造、固體含量高或富含氣體以及對剪切性敏感的液體介質(zhì)。(一).HP系列化工流程旋盤泵處理不同類型流體介質(zhì)的效果和特點1.磨蝕性的顆粒不會研磨和磨損旋轉(zhuǎn)盤片表面，泵的性能和效率不會降低，所以泵的使用壽命長。2.物料受到剪切、攪拌、撞擊等的破壞影響小。3.當處理粘度大的流體介質(zhì)時，實際上粘度越大，效率越高。4.在輸送含有氣體和空氣介質(zhì)時，振動小、噪音低和汽蝕現(xiàn)象隊泵的影響小。(二).HP系列化工流程旋盤泵在多相流物料輸送行業(yè)的應(yīng)用a.由于HP系化工流程旋盤泵的圓盤轉(zhuǎn)子是一種獨特的開放設(shè)計使得泵腔內(nèi)無需按精密的公差配合設(shè)計制造。離心泵的轉(zhuǎn)速是指單位時間內(nèi)離心泵轉(zhuǎn)子的工作次數(shù)，其單位為r/min。合川區(qū)化工泵專業(yè)制造</p><div

這種汽化和凝結(jié)產(chǎn)生泵的沖蝕、振動和性能下降的現(xiàn)象，通常稱之為汽蝕現(xiàn)象。當泵的吸入口和排出口在同一個垂直面上時，為便于安裝閥門，進出口可用偏心異徑管或兩個45°彎頭增大進出口管間距：泵的出口管線要有一定柔性，特別是在高溫高壓條件下，必須經(jīng)過應(yīng)力分析，根據(jù)熱應(yīng)力的大小來確定管線的幾何形狀。泵的出口及深護管線設(shè)計：泵出口不宜直接連接彎頭。泵出口的切斷閥和止回閥間用泄液閥放凈。泵出口壓力表安裝在泵口和止回閥之間的短節(jié)上，也可安裝在出口異徑管上。壓力表接管要有根部閥，壓力表表頭朝向操作面。泵的保護管線-——防凝線:輸送在常溫下凝固的高傾點或高凝固點的液體時，其備用泵和管線應(yīng)設(shè)防凝線，以免備用泵和管線堵塞。一般設(shè)兩根管徑DN20防凝線。其中一根從泵出口切斷閥后接至止回閥前(泵備用時使用)。另一根防凝線是從泵出口切斷閥后接至泵入口切斷閥前(備用泵檢修時使用)。打開相應(yīng)的防凝閥以保證管線內(nèi)流體不凝。泵的保護管線一安全閥線:對于電動往復(fù)泵和旋轉(zhuǎn)泵，應(yīng)在出口側(cè)設(shè)安全閥，當出口壓力超過定壓值時，安全閥啟跳，流體返回入口側(cè)。管線應(yīng)盡量布置緊湊，且不影響操作。泵的保護管線——小流量線:當泵的工作流量低于泵的額定流量30%時。合川區(qū)化工泵專業(yè)制造離心泵葉輪的葉片數(shù)通常采用6～8片，輸送含有雜質(zhì)液體，葉片數(shù)少，2～4片，同時葉片形狀也發(fā)生顯著變化。</p><div

能輸送大的固體顆粒漿料。b.在輸送含有氣體和空氣介質(zhì)時，振動小、噪音低和汽蝕現(xiàn)象隊泵的影響小。由于HP系列化工流程旋盤泵具有上面所述的特點，它能輸送含氣體的三態(tài)混合液體。（三）HP系列化工流程旋盤泵的密封型式HP系列化工流程旋盤泵使用的密封型式有：1.填料密封；2.機械密封又分為：1）彈簧式機械密封；2）集裝式彈簧機械密封；3）金屬波紋管機械密封；4）集裝式金屬波紋管機械密封。所有的密封形式還包括單端面型式和雙端面型式。根據(jù)輸送的不同物料性質(zhì)選用不同的密封材料。集裝式的機械密封拆裝、換、維修方便。雙端面型式的機械密封，泵在開車前必須按泵裝置上的標識位置安裝沖洗管道，必須在開車前打開沖洗管道的閥門進行沖洗，沖洗液的出流方向按圖示。三．HP系列海化工流程旋盤泵成功的業(yè)績HP系列化工流程旋盤泵為用戶不斷帶來新的解決方案，成為越來越多的用戶替換舊泵的優(yōu)先選擇，是解決物料輸送難度極大的應(yīng)用場合的優(yōu)良設(shè)備。：1)冶金行業(yè)：鐵屑、冷卻水、金屬粉末、循環(huán)酸液。2)陶瓷、玻璃和采石行業(yè)：石渣、玻璃纖維、陶瓷渣。3)對剪切敏感、不能被破壞產(chǎn)的品輸送：聚合體乳化劑、乳膠、明膠、石英、膨化劑、活性劑、含有活性劑的化妝品。</p><p> 一直以來，腐蝕就是化工設(shè)備**的危害之一，稍有不慎，輕則損壞設(shè)備，重則造成甚至引發(fā)災(zāi)難。據(jù)有關(guān)統(tǒng)計，化工設(shè)備的破壞約有60%是由于腐蝕引起的，因此在化工泵選型時首先要注意選材的科學性。通常有一種誤區(qū)，認為不銹鋼是"材料"，不論什么介質(zhì)和環(huán)境條件都捧出不銹鋼泵，這是很危險的。下面針對一些常用化工介質(zhì)談?wù)劵け玫倪x材的要點:1、作為強腐蝕介質(zhì)之一，是用途非常的重要工業(yè)原料。不同濃度和溫度的對材料的腐蝕差別較大，對于濃度在80%以上、溫度小于80℃的濃，碳鋼和鑄鐵有較好的耐蝕性，但它不適合高速流動的,不適用作泵閥的材料;普通不銹鋼如304(0Cr18Ni9)、316(0Cr18Ni12Mo2Ti)對介質(zhì)也用途有限。因此輸送的泵閥通常采用高硅鑄鐵(鑄造及加工難度大)、高合金不銹鋼(20號合金)制造。氟塑料具有較好的耐性能，采用襯氟泵(F46)是一種更為經(jīng)濟的選擇。2、鹽酸決大多數(shù)金屬材料都不耐鹽酸腐蝕(包括各種不銹鋼材料)，含鉬高硅鐵也*可用于50℃、30%以下鹽酸。和金屬材料相反，絕大多數(shù)非金屬材料對鹽酸都有良好的耐腐蝕性，所以內(nèi)襯橡膠泵和塑料泵(如聚丙烯、氟塑料等)是輸送鹽酸的比較好選擇。3、硝酸一般金屬大多在硝酸中被迅速腐蝕破壞?；るx心泵的水力損失又稱流動損失，是理論揚程與實際揚程的差值。</p><div

在石化行業(yè),選用的離心泵, 一般情況下，我們選擇20℃的水（運動粘度為1cSt）作為特征測試的泵送介質(zhì)?，F(xiàn)在普遍認為，當運動粘度超過20cSt時，泵機的揚程和流速將略有下降，功率需求將急劇增加，效率將**降低。因此，我們應(yīng)相應(yīng)地校正泵機的性能。 </p> <p> 在這里，小編暫不介紹圖形法，重點給大家介紹下公式校正法的步驟。 </p> <p> 公式校正法的步驟如下： </p> <p> 1、根據(jù)相應(yīng)方程式計算參數(shù)； </p> <p> 2、根據(jù)相應(yīng)方程式校正泵送粘稠液體的流速； </p> <p> 3、根據(jù)相應(yīng)方程式校正泵送粘稠液體時的揚程； </p> <p> 4、根據(jù)相應(yīng)方程式校正泵送粘稠液體時的效率。根據(jù)以上四個步驟即可校正高粘度油品輸送的性能。因此，當泵送水時的泵機性能以及粘稠液體的運動粘度已知時，輸送粘稠液體的泵機的性能可以使用步驟1和步驟4確定。 </p> <p> 當然也有更加便捷的方法, 就是一般泵廠都會提供選型軟件系統(tǒng), 選型軟件系統(tǒng)內(nèi)部都自帶粘度修正功能. </p> <p>
