種布置方式(背靠背或面對面)。O 形圈材料選用耐腐蝕的氟橡膠或全氟橡膠。動靜環(huán)選用硬對硬(碳化鎢或碳化硅)配置。 </p> <p> 強酸強堿泵現(xiàn)場大多采用單端面密封，因而密封背面大多出現(xiàn)結晶結垢，對設備造成腐蝕等現(xiàn)象。為了避免該現(xiàn)象發(fā)生，使現(xiàn)場更加清潔，可直接選用PLAN54(見圖4)。煉油裝置中大多數(shù)酸泵或堿泵的入口壓力較低，浙江容積泵密封廠家批發(fā)，基本為常壓，因此PLAN54 的沖洗源可直接用循環(huán)水。該方案雖然選用了雙端面密封，但從經(jīng)濟角度考慮*增加了一對摩擦副，沒有另外增加輔助系統(tǒng)，既節(jié)約了投資成本又滿足了現(xiàn)場要求，浙江容積泵密封廠家批發(fā)。 O形密封圈雖然密封可靠，浙江容積泵密封廠家批發(fā)，但如果不注意使用條件，也會發(fā)生泄漏。浙江容積泵密封廠家批發(fā)</p><div

潛污泵的作用是將污水中的雜質通過的方式處理。然后排放掉，與清水泵的不同之處使其技術要求也不同于普通類型的設備，它的設計需要考慮到效率、磨損以及特殊環(huán)境：（1）導板等部件自動與著脫耦合，耦合牢固可靠。（2）引出電纜應采用YZW和YCW型橡套電纜或性能相同的電纜，且電纜的密封需采用水密頭式密封，確保潛污泵在使用過程中不至于發(fā)生泄露。（3）葉輪：葉輪設計成無堵塞型式，葉輪皆經(jīng)過靜平衡試驗。葉輪材質為HT200, 符合GB9439-88的要求，過流表面光潔無粘砂、尖角、冷隔、氣孔、砂眼等缺點。（4）主軸材質選用3Cr13經(jīng)調(diào)質處理，有效地、可靠地傳遞動力。主軸與葉輪用鍵連接，以傳遞動力。主軸與葉輪用葉輪螺母鎖緊并有止退墊片，可防止水泵倒轉，造成葉輪松脫。（5）密封環(huán)：材質鑄造青銅，防止因銹蝕而與葉輪咬死。設有密封環(huán)可更大限度地減少內(nèi)部泄露，提高水泵的效率。（6）機械密封：采用兩套單端面非平衡型機械密封。油腔和電機室之間的上部密封單元由陶瓷，石墨組成；泵殼和油腔之間的下部密封單元由碳化硅，碳化硅組成，以防接觸介質。

<p> 高溫重質油泵的介質具有以下共同的特點: </p> <p> 溫度高:一般在340一400℃; </p> <p> 介質粘度大:在溫度下一般運動粘度為(12一180)X 10一6m/s; </p> <p> 介質有顆粒:如催化劑、焦炭、含有砂粒等其他雜質。 </p> <p> 對于高溫重油介質泵用機械密封?，F(xiàn)在各個企業(yè)都采用焊接金屬波紋管械密封?，F(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構，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> 高溫熱油泵 </p> <p> 對于煉油裝置中有一部分泵的介質溫度均在200°C以上，有的甚至超過300 °C，此時若機械密封沖洗方案的選擇為PLAN53B，應多加考慮PLAN53B 系統(tǒng)中蓄能器皮囊的耐溫問題。通常情況下，蓄能器皮囊若為普通橡膠材質，耐溫不超過120 °C，即使是氟橡膠耐溫也不超過200 °C。 </p> <p> API 682 中PLAN53B 系統(tǒng)的布置方式如圖1 所示，從圖中可以看出高溫的密封隔離液從密封腔直接經(jīng)過蓄能器，然后再經(jīng)過冷卻器，再回到密封腔。此種布置方式在隔離液溫度升高之后，可能會導致蓄能器內(nèi)介質溫度升高，致使皮囊失效。軸彎曲變形時橫截面形心沿與軸線垂直方向的線位移稱為撓度，機械密封要求兩個密封端面之間受力均勻。</p><div

口環(huán)，也叫耐磨環(huán)。其主要作用是防止出口端介質倒流回進口端介質也就是密封作用（因此有“密封環(huán)”這一名稱）；同時也起耐磨作用，避免葉輪和泵殼直接接觸損壞，有保護葉輪的作用（因此有“耐磨環(huán)”這一名稱）。</span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)，一般水泵的級數(shù)與口環(huán)的數(shù)量是一樣的，也就是說一個5級的水泵，那么口環(huán)也就有5個，一個首口環(huán)，4個口環(huán)。</span> </p> <p> <span style="font-size:12px;">多級離心泵口環(huán)的作用是在葉輪與泵殼間形成狹窄、曲折的通道，來增加介質的流動阻力，達到減少介質泄漏的目的。離心泵口環(huán)的設置還起到保護泵上主要零件不受磨損的作用(公眾號:泵管家)，在口環(huán)磨損后，可以修復或更換新環(huán)、恢復正常裝配間隙，這樣既經(jīng)濟又便于檢修。</span> </p> <p> <span style="font-size:12px;">口環(huán)間隙大會將低泵的使用效率，經(jīng)過泵加壓的流體會過多的從泵出口區(qū)域沿葉輪與口環(huán)的間隙返回到進口，從而降低了泵的使用效率，同時由于流量的加大，會使口環(huán)過早的被磨損。口環(huán)間隙過大，會導致泵的流量降低，嚴重時不上量。 </span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)的完好性及它與葉輪問徑向間隙含，在拆卸泵時應首先檢查。如離心泵口環(huán)已有溝槽等缺損或已破裂或間隙艿超過表5中所規(guī)定的數(shù)值時，應更換新口環(huán)或將原口環(huán)補焊修復。</span> </p> <p> <br /> </p> <p> <br /> 機械密封的正常運行必須具備以下條件：機械密封的泵軸撓度要小，加上機械密封自身性能，才能達到密封效果。浙江容積泵密封廠家批發(fā)</p><p style="text-indent:25px">密封件的存放室溫比較好在30℃以下，避免密封件產(chǎn)生高溫老化。浙江容積泵密封廠家批發(fā)</p><p> 為了使密封面之間始終保持互相配合，彈簧起到了機械密封與運動主軸之間的恒定調(diào)節(jié)作用。當旋轉面和主軸之間采用人造橡膠密封時，該彈性體就會在主軸上來回運動。這種重復摩擦動作，會磨蝕主軸上的防腐材料，失去主軸的氧化膜保護層，**終會在主軸的摩擦面上形成磨損溝槽，造成液體從溝槽中泄漏，并增加必要的維修工作量或甚至更換主軸。為了解決這一問題，一般在填料盒內(nèi)安裝一個可更換的軸套。 </p> <p> 然而，解決腐蝕磨損問題的長久辦法是去除其內(nèi)部的動態(tài)密封?，F(xiàn)在，大部分主要密封制造廠生產(chǎn)非腐蝕磨損型密封，以防止液泵零件的腐蝕磨損。浙江容積泵密封廠家批發(fā)</p><p
