化工泵油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場合的化工泵上。 &nb"><meta name="keywords" content="江蘇葉輪泵密封銷售廠家,封"><link

化工泵油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場合的化工泵上。 </p> <p> 化工泵依靠離心原理來抽取液體物料，特殊材料制成的化工泵適用于瓶、桶、缸、池或其他容器中抽取腐蝕性液體。由于化工泵所抽取的介質(zhì)有腐蝕、揮發(fā)、等危險(xiǎn)性的存在，對泵體的密封性能要求，要比其他種類的泵高很多。 </p> <p> 化工泵油封應(yīng)安裝在制造精度為h8～h9，表面粗糙度為1.6～0.8μm且經(jīng)過表面硬化處理的軸上。密封介質(zhì)不應(yīng)含有固體微粒和雜質(zhì)，江蘇葉輪泵密封銷售廠家，否則會造成油封和軸的迅速磨損而使密封失效。 </p> <p> 在選擇此種密封方法是，要充分考慮化工泵所輸送到物料的性能和要求，以避免不必要的泄漏，防止意外的發(fā)生，江蘇葉輪泵密封銷售廠家。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 介質(zhì)的低于飽和蒸汽壓力，江蘇葉輪泵密封銷售廠家，使得端面液膜發(fā)生閃蒸，喪失潤滑。江蘇葉輪泵密封銷售廠家</p><div

機(jī)械密封的平衡對接觸面的密封壓力有很大影響。這一密封壓力取決于密封本身的有效截面以及填料盒內(nèi)的壓力。 </p> <p> 非平衡型密封的旋轉(zhuǎn)面相反一側(cè)的截面完全暴露于填料盒的壓力范圍之下，這種情況會使密封面之間產(chǎn)生很高的密封壓力，從而會使工作溫度提高，加快磨損速度。在高溫工作條件下或液體具有較大腐蝕性和磨擦性的情況下，會較大程度降低機(jī)械密封的使用壽命。 </p> <p> 對機(jī)械密封加以平衡，可降低密封壓力，延長密封的使用壽命。一般采用帶有臺階的主軸和軸套，降低旋轉(zhuǎn)面的有效截面，就可達(dá)到上述目的。不過千萬別將凈密封壓力調(diào)節(jié)到接近零的水平，因?yàn)檫@樣做的結(jié)果可能會造成密封面之間的工作狀況不穩(wěn)定，并可能會因突然的變故而將密封吹開。 </p> <p> 解決這些密封問題的答案也許是采用非平衡式密封，對于某些服務(wù)來說，也許采用非平衡式密封能達(dá)到更好的效果。例如，在某些應(yīng)用領(lǐng)域，與密封的使用壽命相比，也許更強(qiáng)調(diào)對液體泄漏造成的安全性問題。在這種情況下，對密封的選用也許可理解為更希望選擇具有較高的密封壓力。同樣，在選用較冷液體的密封時(shí)，操作溫度的增加也許是微不足道的。 </p> <p> 不管出于何種考慮，當(dāng)填料盒的壓力超過50psi時(shí)，一般推薦使用平衡式密封。浙江容積泵密封中間商為了比較大發(fā)揮機(jī)械密封的實(shí)際性能，應(yīng)對密封環(huán)的使用進(jìn)行調(diào)查，掌握其工作壓力、溫度等情況，合理進(jìn)行選擇。</p><div style="width:100%;text-align:

對石化行業(yè)來說，高溫重質(zhì)油泵用機(jī)械密封的選用一直是一大難題，例如催化裂化油漿泵、回?zé)捰捅?、常壓塔底泵、初餾塔底泵、減壓塔底泵、延遲焦化的輻射進(jìn)料泵等。 </p> <p> 高溫重質(zhì)油泵的介質(zhì)具有以下共同的特點(diǎn): </p> <p> 溫度高:一般在340一400℃; </p> <p> 介質(zhì)粘度大:在溫度下一般運(yùn)動粘度為(12一180)X 10一6m/s; </p> <p> 介質(zhì)有顆粒:如催化劑、焦炭、含有砂粒等其他雜質(zhì)。 </p> <p> 對于高溫重油介質(zhì)泵用機(jī)械密封?，F(xiàn)在各個企業(yè)都采用焊接金屬波紋管械密封。現(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結(jié)構(gòu)，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。 </p><p> 泵用機(jī)械密封選型要點(diǎn) </p> <p> 美國石油協(xié)會API 682(Pumps-Shaft Sealing Systems for Centrifugal and Rotary Pumps)標(biāo)準(zhǔn)中對機(jī)械密封的類別(Categories)、類型(Types)、布置方式(Arrangements)、沖洗方案(Flush plans)等進(jìn)行了分類，在工程應(yīng)用中機(jī)械密封的選型也應(yīng)注重以上要點(diǎn)進(jìn)行分析。 </p> <p> 另外，機(jī)械密封的 pV 值是選擇、使用和設(shè)計(jì)機(jī)械密封的重要參數(shù)，功耗、磨損與溫升都與該值有關(guān)。pV 值越高，機(jī)械密封的技術(shù)水平及難度系數(shù)越高。 </p> <p> 機(jī)械密封類別(Categories)的選擇泵中常用的是橡膠O型圈。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇葉輪泵密封銷售廠家,封"

排污泵采用獨(dú)特的單葉片或雙葉片葉輪結(jié)構(gòu)，**提高了污物通過能力，能有效的通過泵口徑的5倍纖維物質(zhì)與直徑為泵口徑約50%的固體顆粒。機(jī)械密封采用新型硬質(zhì)耐腐的碳化鎢材料，同時(shí)將密封改進(jìn)為雙端面密封，使其長期處于油室內(nèi)運(yùn)行，可使泵安全連續(xù)運(yùn)行8000小時(shí)以上。整體結(jié)構(gòu)緊湊、體積小、噪聲小、節(jié)能效果優(yōu)良，檢修方便，無需建泵房，潛入水中即可工作，減少工程造價(jià)。
