100多年來，人們采用填料一類的多種密封材料，使液體從液泵殼體沿著主軸的向外泄漏量不斷減少。盡管現(xiàn)代工藝流程中采用的液泵，仍然較大程度地沿用**古老的密封設(shè)計——填料盒，因為其起步費用低，而且又為工廠的工作人員所熟悉。 </p> <p> 然而，由于環(huán)境問題的關(guān)系，采用填料密封的方法已逐漸不能被人們所接受，淮安污水密封經(jīng)銷廠家，特別是針對現(xiàn)代工藝流程中比較普遍的，淮安污水密封經(jīng)銷廠家、腐蝕性較強的液體而言，淮安污水密封經(jīng)銷廠家。因此，在實際應(yīng)用中，以機械密封代替填料密封的情況越來越多。 </p> <p> <br /> </p><div

src="https://tyunfile.71360.com/UploadFile/lscmjx/637247295241855469/6155112.jpg"></div><p> 隨著工業(yè)技術(shù)和密封技術(shù)的發(fā)展，泵在電力、化工、石油等多個行業(yè)大量使用，對泵密封的密封性和可靠性要求更高、更嚴。化工泵的密封對整個設(shè)備運轉(zhuǎn)來說起著重要的作用，化工泵的密封系統(tǒng)泄漏將會嚴重影響到設(shè)備的正常運轉(zhuǎn)。尤其是高溫高壓泵的發(fā)展,更使得對泵的密封更加嚴格?；け眯孤c </p> <p> 泵用機械密封種類繁多，型號各異，但泄漏點主要有五處： </p> <p> 軸套與軸間的密封動環(huán)與軸套間的密封動、靜環(huán)間密封對靜環(huán)與靜環(huán)座間的密封密封端蓋與泵體間的密封 </p> <p> 現(xiàn)象：操作中密封發(fā)出爆裂聲（端面爆裂聲） </p> <p> 可能的原因：密封液在密封界面汽化；加強密封面的冷卻 </p> <p> 解決方法：增加旁路沖洗管線（如果沒有的話）擴大旁路沖洗管線和/或壓蓋上的開孔。 </p> <p> 現(xiàn)象：密封連續(xù)滴漏 </p> <p> 可能的原因：表面不平；石墨密封面起泡；密封面產(chǎn)生熱變形 </p> <p> 解決方法：在安裝過程中，輔助密封被劃傷O形圈老化，由于壓縮形變輔助密封變硬變脆由于化學(xué)作用輔助密封變軟變粘。 </p> <p> 現(xiàn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="淮安污水密封經(jīng)銷廠家" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247298675996094/8215396.jpg"></div><p> <p> 在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動和停機時，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來代替)。 </p> <p> 大部分機械密封的設(shè)計采用較軟的材料來制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來，**通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。 </p> <p> 不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤滑的作用。然而，在填料盒內(nèi)，采用彈簧負載和液體壓力相結(jié)合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會影響接觸面之間形成液體薄膜，導(dǎo)致熱量增加和過早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。 </p> <p> 密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進行研磨。然后，采用單色光源的光柵板對其檢測。從這一觀點出發(fā)，對這些密封接觸面必須小心處理，并嚴格按照安裝說明，保證密封面得到適當?shù)谋Ｗo和正確就位，這一點是非常重要的。 </p> <p> <br /> </p> </p><div style="width:100%;text-align: center;"><img
