石油化工流程泵大都選用內(nèi)流型機械密封，只有在壓力和溫度不高的腐蝕性介質(zhì)中才選用外流型機械密封。按補償機構(gòu)中彈簧的數(shù)量可分為多彈簧和單彈簧機械密封。補償機構(gòu)中有多個彈簧的密封稱為多彈簧機械密封（圖5）；補償機構(gòu)中只有一個彈簧的機械密封稱為單彈簧機械密封（圖6），多彈簧機械密封又稱小彈簧機械密封，這種結(jié)構(gòu)軸向尺寸較小，可用改變彈簧數(shù)量的方法改變彈性力，軸向力較均勻，適用于高速機械密封，在腐蝕性介質(zhì)中不宜采用。單彈簧機械密封又稱大彈簧機械密封，密封結(jié)構(gòu)較為簡單。有的密封型式還用彈簧傳遞扭矩。國產(chǎn)密封應(yīng)用大彈簧較多，但不能用于高速。圖5多彈簧機械密封圖6單彈簧機械密封補償機構(gòu)的作用是使密封端面緊密貼合，為達到此目的，采用的方法有兩種，一是彈性力，二是磁力。只有在系統(tǒng)內(nèi)壓力較低時采用磁力機械密封（圖7），大多數(shù)都用前者。除了用彈簧形成彈性力外還有用波紋管的，稱為波紋管式機械密封。波紋管的材料可用橡膠、聚四氟乙烯和焊接的金屬薄片（圖8）等，遼源SAB-35安德里茲泵用機械密封。（圖8）根據(jù)密封面上介質(zhì)載荷的作用情況可分為平衡型和非平衡型密封（圖9），遼源SAB-35安德里茲泵用機械密封。非平衡型：載荷系數(shù)k≥1的密封稱為非平衡型密封，遼源SAB-35安德里茲泵用機械密封，換言之。安德里茲泵用機械密封。遼源SAB-35安德里茲泵用機械密封</p><div

6）對某些靠彈簧傳動的機械密封必須注意彈簧的旋向，即軸旋轉(zhuǎn)方向應(yīng)使彈簧越來越緊，否則會造成密封失效，彈簧旋向的選擇由下述方法確定：由靜環(huán)向動環(huán)看，軸順時針旋轉(zhuǎn)用右旋彈簧，反之，則選用左旋彈簧。3、機械密封的安裝方法機械密封部件無論從制造精度上或安裝精度上要求都很嚴(yán)格，如果安裝不當(dāng)，就會影響密封的壽命和密封性能，嚴(yán)重時將會使密封迅速失效。（1）安裝前的準(zhǔn)備工作及安裝注意事項①檢查要進行安裝的機械密封的型號、規(guī)格是否正確無誤，零件是否缺少。②檢查機械密封各元件是否有損壞，特別是動環(huán)和靜環(huán)的密封端面是否碰傷，如發(fā)現(xiàn)損壞時，需進行返修或更換新的零件。各密封元件需用汽油或煤油清洗干凈，保持各元件表面無灰塵、異物。③軸或軸套表面及密封腔內(nèi)壁、密封端蓋內(nèi)表面是否有毛刺、溝痕等。如發(fā)現(xiàn)毛刺、溝痕時應(yīng)修平、打光，并用汽油或煤油清洗，保持清潔，不許有灰塵雜物附在表面上。④不要用不干凈的布或棉紗布擦洗動環(huán)和靜環(huán)表面，應(yīng)使用干凈柔軟的紗布、脫脂棉之類的東西擦洗。⑤裝配過程中應(yīng)保持清潔，保證動環(huán)、靜環(huán)的密封端面不被劃傷、碰破，為了更于裝入，裝配時應(yīng)在軸或軸套表面、壓蓋與密封圈配合表面涂抹機油。</p><p> 從受力角度考慮過窄不利，破壞和變形的可能性增加了＞俐，密封端面的直徑又是載荷系數(shù)的函數(shù)。因此，密封端面的寬度應(yīng)綜合考慮。一般地講，對普通介質(zhì)密封端面隨直徑的增大而加寬。對于輕烴類介質(zhì)，端面寬度比在普通介質(zhì)中寬一些：而高速機械密封，端面寬度相對地窄一些，否則發(fā)熱量太大，不能正常運轉(zhuǎn)，一般在3mm左右。環(huán)直徑（mm、環(huán)寬（mm）－20～602～460～1004～6100～2005—7四、密封環(huán)的技術(shù)要求：1）密封端面的平面度不大于0．0009mm（即三個單色光干涉帶）；硬質(zhì)材料密封端面粗糙度Ra值不大于0．2μm（相當(dāng)于Δ10）；軟質(zhì)材料密封端面粗糙度Ra值不大于0．4μm(相當(dāng)于Δ9)，表面不應(yīng)有裂紋、劃傷、氣孔和疏松等影響使用性能的缺陷。2）密封環(huán)的密封端面與輔助密封圈接觸的端面平行度按GBll84－80的7級精度規(guī)定。3）密封環(huán)端面與安裝輔助密封圈的內(nèi)（或外）圓表面的垂直度應(yīng)按GBll84－80的7級精度的規(guī)定。4）密封環(huán)與輔助密封圈接觸部位的表面粗糙度凡值不大于3．2μm；外圓或內(nèi)孔尺寸公差為hg或Hg。上述要求是對普通泵用機械密封的密封環(huán)而言，對轉(zhuǎn)速較低的釜用機械密封可適當(dāng)放寬或參考相應(yīng)的標(biāo)準(zhǔn)，而對高速機械密封則要求更高。五、平面度平面度。錫林郭勒SAB-35-QRXG-GA121489安德里茲泵用機械密封。</p><div

稱為環(huán)座）則用普通材料制成。為解決硬質(zhì)合金環(huán)和環(huán)座之間的聯(lián)接和密封，產(chǎn)生了熱裝式、帶密封圈式、焊接和釬焊四種組合式密封環(huán)。帶O型圈的組合式由匐環(huán)結(jié)構(gòu)封環(huán)在硬質(zhì)合金環(huán)與環(huán)座之間用H7／g8的滑動配合。在兩者配合圓柱面間置一聚四氟乙烯或合成橡膠制成的O形密封圈，防止其間的密封流體泄漏，且將硬質(zhì)合金環(huán)與環(huán)座組合在一起。在硬質(zhì)合金環(huán)與環(huán)座的平面結(jié)合處設(shè)一銷釘，以傳遞扭矩。此種組合結(jié)構(gòu)，無組合應(yīng)力產(chǎn)生／也無由此引起的組合密封環(huán)的密封端面的變形，但是組合密封環(huán)零件的數(shù)量增加了，還需要在硬質(zhì)合金環(huán)上鉆孔或槽，給制造增加了難度，同時由于增設(shè)了o形圈，密封環(huán)的使用溫度受到了限制。熱裝式密封環(huán)的結(jié)構(gòu)為提高帶O形圈密封環(huán)的使用溫度，出現(xiàn)了熱裝式密封環(huán)。它是靠硬質(zhì)合金環(huán)和環(huán)座之間的過盈配合來傳遞扭矩并實現(xiàn)密封，是目前應(yīng)用多的一種密封環(huán)（圖23）。這種密封環(huán)組合時將環(huán)座加熱，環(huán)座孔受熱脹大，放入硬質(zhì)合金環(huán)，冷卻之后兩者在過盈下完成組合，再在常溫下研磨和拋光密封端面到要求的精度。這種環(huán)的缺點是，隨著時間的推移，環(huán)境和使用溫度的變化，密封端面的平面度將發(fā)生變化而不符合要求。究其原因，一是熱裝結(jié)構(gòu)本身存在過盈。JCS2A-115安德里茲泵用機械密封。遼源SAB-35安德里茲泵用機械密封</p><p

機械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。3．選擇金屬波紋管機械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機封中，金屬波紋管取代了普通機封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。二、低溫下的機械密封在煉油化工裝置中，低溫輸送的介質(zhì)一般都具有豁度小、潤滑性差、容易氣化的特點，而且介質(zhì)在氣化時大量吸熱，使周圍溫度急劇下降，造成空氣中水氣的凝結(jié)，導(dǎo)致端面及其周圍結(jié)冰，使端面貼合不嚴(yán)引起泄漏。同時，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時轉(zhuǎn)移，必然會加劇端面處的氣化，造成惡性循環(huán)，加速密封面的早期失效。另外，低溫密封的輔助密封圈在低溫下發(fā)硬失彈也容易導(dǎo)致泄漏。對低溫密封，除了選擇合適的輔助密封圈材質(zhì)外，還要注意以下幾點。遼源SAB-35安德里茲泵用機械密封</p><p
