機械密封的作用一、提高機器效率、降低能耗。1、減少機器的內(nèi)漏，WQ3260-211-65凱泉泵用機械密封、外漏和穿漏，提高機器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機械密封，使泵效率提高。2、減少摩擦損失，提高機器的機械效率。例如，WQ3260-211-65凱泉泵用機械密封，將雙端面密封改為單端面密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失，提高機械效率。3、改變密封方式，提高機器或機組的效率，WQ3260-211-65凱泉泵用機械密封。例如，將屏蔽泵改用機械密封泵，使電動機效率提高;采用磁力傳動泵，提高機器效率。4、改變輔助系統(tǒng)，減少能耗，提高機組效率。例如，熱油泵自沖洗改為小葉輪循環(huán)沖洗;雙端面密封改為單端面密封，節(jié)省封油輔助系統(tǒng)的能耗。二、節(jié)約原材料。例如，工藝流體回收，減少或消除動力蒸汽和工藝流體的損耗，減少封油損耗等。三、提高機器可靠性。例如，軸封的漏損和壽命決定軸封和機器的可靠性。四、安全和環(huán)境保護。根據(jù)日本某廠調(diào)查報告，在發(fā)生的786件事故中有32件是泄漏造成的(占42%)。此外工藝流體泄漏還會造成環(huán)境污染，包括對大氣污染、水污染和車間環(huán)境污染。機械密封的安裝（1）熟悉設備情況。安裝機械密封之前，對轉軸的轉速、軸徑等都要進行熟悉。KQDP25-2S凱泉泵用機械密封。WQ3260-211-65凱泉泵用機械密封</p><div

機械密封用于各種類型的泵。機械密封是一種精度較高的密封裝置，對安裝和使用條件均有一定的要求。1、機械密封安裝使用的一般原則(1)弄清設備的情況，要了解設備轉軸的轉速、軸徑;設備制造精度及密封腔尺寸，設備本身的使用壽命以及設備在生產(chǎn)工藝中的地位等要做均衡的考慮。(2)估算介質(zhì)壓力。泵的密封腔壓力一般不是泵的出口壓力，而是低于泵的出口壓力。(3)弄清密封介質(zhì)情況。要知道密封介質(zhì)的狀態(tài)，是氣態(tài)還是液態(tài)，介質(zhì)是否含顆粒及顆粒狀況;了解介質(zhì)的性質(zhì)、溫度，以便合理選型及采取必要的冷卻、沖洗、潤滑措施。2、機械密封安裝使用的技術要求(1)安裝機械密封部位的軸或軸套的徑向跳動公差：Ф10~50mmФ50~120mm,。軸或軸套的表面粗糙度應符合技術要求，外徑尺寸公差為h6。(2)傳動軸的軸向竄動量不超過。(3)密封腔體端面對軸表面的跳動公差：軸或軸套外徑端面跳動公差:Ф10~50mm，Ф50~120mm,(4)軸或軸套的端面及密封腔體的端面要有倒角。軸徑≤Φ30mm時為3×10°，軸徑>Φ30mm時為4×10°。(5)當輸送介質(zhì)溫度偏高、過低或含有雜質(zhì)顆粒、易燃、易爆、有毒時，應采取相應的阻封、沖洗、冷卻、過濾等措施。(6)對某些靠彈簧傳動的機械密封必須注意彈簧的旋向。WQ3260-211-65凱泉泵用機械密封DG48-50凱泉泵用機械密封。</p><div

機械密封件介紹機械密封件屬于精密、結構較為復雜的機械基礎元件之一，是各種泵類、反應合成釜、透平壓縮機、潛水電機等設備的關鍵部件。其密封性能和使用壽命取決于許多因素，如選型、機器的精度、正確的安裝使用等。1、機械密封的基本概念機械密封是指由至少一對垂直于旋轉軸線的端面在流體壓力和補償機構彈力（或磁力）的作用下以及輔助密封的配合下保持貼合并相對滑動而構成的防止流體泄漏的裝置。補償環(huán)的輔助密封為金屬波紋管的稱為波紋管機械密封。2、機械密封的組成主要有以下四類部件。a.主要密封件：動環(huán)和靜環(huán)。b.輔助密封件：密封圈。c.壓緊件：彈簧、推環(huán)。d.傳動件：彈箕座及鍵或固定螺釘。應注意問題1、安裝時注意事項（1）要十分注意避免安裝中所產(chǎn)生的安裝偏差a、上緊壓蓋應在聯(lián)軸器找正后進行，螺栓應均勻上支，防止壓蓋端面偏斜，用塞尺檢查各點，其誤差不大于。b、檢查壓蓋與軸或軸套外徑的配合間隙（即同心度），四周要均勻，用塞尺檢查各點允差不大于。（2）彈簧壓縮量要按規(guī)定進行，不允許有過大或過小現(xiàn)象，要求誤差。過大會增加端面比壓，另速端面磨損。過小會造成比壓不足而不能起到密封作用。（3）動環(huán)安裝后髯保證能在軸上靈活移動。</p><p> 將動環(huán)壓向彈簧后應能自動彈回來。2、拆卸時注意事項（1）在拆卸機械密封時要仔細，嚴禁動用手錘和扁鏟，以免損壞密封元件。可做一對鋼絲勾子，在對自負盈虧方向伸入傳動座缺口處，將密封裝置拉出。如果結垢拆卸不下時，應清洗干凈后再進行拆卸。（2）如果在泵兩端都用機械密封時，在裝配，拆卸過程中互相照顧，防止顧此失彼。（3）對運行過的機械密封，凡有壓蓋松動使密封發(fā)生移動的情況，則動靜環(huán)零件必須更換，不應重新上緊繼續(xù)使用。因為在之樣楹動后，摩擦副原來運轉軌跡會發(fā)生變動，接觸面的密封性就很容易遭到破壞。機械密封件正常運行和維護1、啟動前的準備工作及注意事項（1）檢查機械密封，以及附屬裝置和管線安裝是否齊全，是否符合技術要求。（2）機械密封啟動前進行靜壓試驗，檢查機械密封是否有泄漏現(xiàn)象。若泄漏較多，應查清原因設法消除。如仍無效，則應拆卸檢查并重新安裝。一般靜壓試驗壓力用2~3公斤/平方厘米。（3）按泵旋向盤車，檢查是否輕快均勻。如盤車吃力或不動時，則應檢查裝配尺寸是否錯誤，安裝是否合理。2、安裝與停運（1）啟動前應保持密封腔內(nèi)充滿液體。對于輸送凝固的介質(zhì)時，應用蒸氣將密封腔加熱使介質(zhì)熔化。啟動前必須盤車。MD100-50凱泉泵用機械密封。</p><div

一、品名：油封環(huán)用途：可用于閥門、螺桿、泵、壓縮機等密封部位起到防止液體、氣體等泄漏的密封作用。品牌：OmniSeal。材質(zhì)與結構：（一）聚四氟乙烯夾套，不銹鋼擋圈以及游絲合金彈簧等材料制成。夾套為密封環(huán)的外殼，不銹鋼擋圈起到增強作用，中心的彈簧起到提供彈力增加密封性能的作用，整個油封環(huán)無機械性能。（二）聚四氟乙烯夾套及游絲合金彈簧等材料制成。歸類分析：有兩個意見：意見一：油封環(huán)不帶活動件意見二：機械密封件帶活動件（有彈簧）產(chǎn)品圖片：二、機械密封件（例如：滑動密封環(huán)及彈簧密封環(huán)）是機械裝配件，裝于機器或裝置上形成平面、旋轉面的密封結合，以防止高壓泄露，抵御由于部件運動或振動等產(chǎn)生的壓力及應力。這些密封件的結構通常十分復雜，由以下兩個部分組成：（一）固定件：當將密封件裝上后就成為機器或裝置不可分割的組成部分；以及（二）活動件：旋轉件、彈簧件等。該貨品之所以稱為“機械密封件”，主要是因為有上述活動件。這些密封件起抗振裝置、軸承、實際封件的作用，有時還起接頭的作用，其應用范圍廣，包括用于泵、壓縮機、混合器、攪拌器及汽輪機。它們用不同材料制成，外形也各不相同。三、油封環(huán)。KQDP100-64凱泉泵用機械密封。WQ3260-211-65凱泉泵用機械密封</p><p style="text-indent:25px">凱泉泵用機械密封KQWR-G150-315。WQ3260-211-65凱泉泵用機械密封</p><p> 2）橡膠O形墊圈：斷面形狀是正圓，有一定的自緊作用，密封效果比平墊圈好，壓緊力更小。（3）塑料平墊圈：塑料的特點是耐腐蝕性好,大部分塑料耐溫性能不好。聚四氟乙烯為塑料之冠，不但耐腐蝕性能優(yōu)異，而且耐溫范圍比較寬闊，可在-180℃～+200℃之內(nèi)長期使用。（4）聚四氟乙烯包墊圈：為了充分發(fā)揮聚四氟乙烯的優(yōu)點，同時彌補它彈性較差的缺點，做成聚四氟乙烯包裹橡膠或石棉橡膠的墊圈。這樣，既同聚四氟乙烯平墊圈一樣耐腐蝕，又有良好的彈性，增強密封效果，減小壓緊力。其斷面形狀如圖4-20所示。（5）石棉橡膠墊圈：由石棉橡膠板剪成。它的組分是60～80%的石棉和10～20%的橡膠，以及填充劑、硫化劑等。它有很好的耐熱性、耐冷性、化學穩(wěn)定性，而且貨源豐富，價格便宜。使用時，壓緊力不必很大。由于它能粘附金屬，所以表面涂一層石墨粉，以免拆卸時費勁。石棉橡膠板有四種顏色：灰色，用于低壓(牌號XB-200，耐壓≤16公斤/平方厘米，耐溫200℃)；紅色，用于中壓(牌號XB-350，耐壓可達40公斤/平方厘米，耐溫350℃)；紫紅色，用于高壓(牌號XB-450，耐壓100公斤/平方厘米耐溫450℃)；綠色，用于油類，耐壓性能也很好。（6）金屬平熱圈：鉛，耐溫100℃；鋁430℃；銅315℃。WQ3260-211-65凱泉泵用機械密封</p></p><br
