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(shè)備的情況，要了解設(shè)備轉(zhuǎn)軸的轉(zhuǎn)速、軸徑;設(shè)備制造精度及密封腔尺寸，設(shè)備本身的使用壽命以及設(shè)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，撫州神通博格曼機械密封件MFLWKT80。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(shù)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(yīng)符合技術(shù)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，撫州神通博格曼機械密封件MFLWKT80、易爆、有毒時，應(yīng)采取相應(yīng)的阻封、沖洗、冷卻，撫州神通博格曼機械密封件MFLWKT80、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。神通博格曼機械密封件212。撫州神通博格曼機械密封件MFLWKT80</p><div

沖洗液可以是熱水或蒸汽。九、機械密封典型失效原因分析（一）機械密封本身問題1、鑲裝不到位或不平整。2、載荷系數(shù)太大或端面比壓設(shè)計不合理。3、材質(zhì)選用不當。4、密封面不平。5、密封面太寬或太窄。（二）輔助系統(tǒng)問題1、工況條件復(fù)雜，但沒有沖洗等輔助設(shè)施。2、沖洗管堵塞。3、冷卻管結(jié)垢。（三）介質(zhì)及工作條件問題1、介質(zhì)腐蝕性強。2、介質(zhì)中有固體顆粒。3、設(shè)備抽空。4、密封面結(jié)晶。5、介質(zhì)粘度太大。（四）泵的問題1、軸的加工精度不佳、串軸、跳動、安裝間隙過大。2、泵開啟后振動太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機械密封安裝沒有達到應(yīng)有的壓縮量。十、常見的滲漏現(xiàn)象機械密封滲漏的比例占全部維修泵的50%以上，機械密封的運行好壞直接影響到水泵的正常運行，現(xiàn)總結(jié)分析如下：1、周期性滲漏（1）泵轉(zhuǎn)子軸向竄動量大，輔助密封與軸的過盈量大，動環(huán)不能在軸上靈活移動。在泵翻轉(zhuǎn)，動、靜環(huán)磨損后，得不到補償位移。對策：在裝配機械密封時，軸的軸向竄動量應(yīng)小于0．1mm，輔助密封與軸的過盈量應(yīng)適中，在保證徑向密封的同時，動環(huán)裝配后保證能在軸上靈活移動（把動環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤滑油量不足引起干摩擦或拉毛密封端面。撫州神通博格曼機械密封件FMY212神通博格曼機械密封件CS。</p><div

現(xiàn)在還在不斷更新。零泄漏密封技術(shù)過去總認為接觸式和非接觸式機械密封不可能達到零泄漏（或無泄漏）。以色列利用開槽密封技術(shù)，提出零泄漏非接觸式機械端面密封的新概念，并已用于核電站潤滑油泵中。干運轉(zhuǎn)氣體密封技術(shù)這類密封是將開槽密封技術(shù)用于氣體密封。上游泵送密封技術(shù)即利用密封面上開流槽將下游少量泄漏流體泵送回上游。上述幾類密封的結(jié)構(gòu)特點是：采用淺槽，且膜厚和流槽的深均屬微米級，并采用潤滑槽，徑向密封壩和周向密封堰組成密封和承載部分。也可以說開槽密封是平面密封和開槽軸承的結(jié)合。其優(yōu)點是泄漏量?。ㄉ踔翢o泄漏）、膜厚大，消除接觸摩擦、功耗和發(fā)熱量小。熱流體動壓密封技術(shù)它是利用各種形狀較深的密封面流槽，造成局部熱變形，以產(chǎn)生流體動力楔效應(yīng)。這種具有流體動壓承載能力的密封，稱之為熱流體動力楔密封。波紋管密封技術(shù)可分為成型金屬波紋管和焊接金屬波紋管機械密封技術(shù)。多端面密封技術(shù)分為雙密封、中間環(huán)密封、多密封技術(shù)。另外還有平行面密封技術(shù)、監(jiān)控密封技術(shù)、組合密封技術(shù)等。八、機械密封沖洗方案及特點沖洗的目的在于防止雜質(zhì)集積，防止氣囊形成，保持和改善潤滑等，當沖洗液溫度較低時，兼有冷卻作用。</p><p> 機械密封是靠一對或數(shù)對垂直于軸作相對滑動的端面在流體壓力和補償機構(gòu)的彈力(或磁力)作用下保持貼合并配以輔助密封而達到阻漏的軸封裝置。機械密封常用材料的選用清水;常溫;(動)9Cr18，1Cr13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂石墨，青銅，酚醛塑料。河水(含泥沙);常溫;(動)碳化鎢，(靜)碳化鎢海水;常溫;(動)碳化鎢，1Cr13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂石墨，碳化鎢，金屬陶瓷;過熱水100度;(動)碳化鎢，1Cr13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂石墨，碳化鎢，金屬陶瓷;汽油，潤滑油，液態(tài)烴;常溫;(動)碳化鎢，1Cr13堆焊鈷鉻鎢，鑄鐵;(靜)浸樹脂或錫銻合金石墨，酚醛塑料。汽油，潤滑油，液態(tài)烴;100度;(動)碳化鎢，1Cr13堆焊鈷鉻鎢;(靜)浸青銅或樹脂石墨。汽油，潤滑油，液態(tài)烴;含顆粒;(動)碳化鎢;(靜)碳化鎢。密封材料的種類及用途密封材料應(yīng)滿足密封功能的要求。由于被密封的介質(zhì)不同，以及設(shè)備的工作條件不同，要求密封材料的具有不同的適應(yīng)性。對密封材料的要求一般是：1)材料致密性好，不易泄露介質(zhì);2)有適當?shù)臋C械強度和硬度;3)壓縮性和回彈性好，變形小;4)高溫下不軟化，不分解，低溫下不硬化，不脆裂;5)抗腐蝕性能好，在酸，堿，油等介質(zhì)中能長期工作，其體積和硬度變化小。河北神通博格曼機械密封件。</p><div

1）大多數(shù)潛污泵機械密封拆解后，靜環(huán)和動環(huán)的輔助密封件無彈性，有的已經(jīng)腐爛，造成了機封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對靜環(huán)和動環(huán)輔助橡膠密封件的腐蝕作用，造成了機械滲漏過大，動、靜環(huán)橡膠密封圈材料為丁腈—40，不耐高溫，不耐酸堿，當污水為酸性堿性時易腐蝕。對策：對腐蝕性介質(zhì)，橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。（2）固體顆粒雜質(zhì)引起的機械密封滲漏如果固體顆粒進入密封端面，將會劃傷或加快密封端面的磨損，水垢和油污在軸（套）表面的堆積速度超過摩擦副的磨損速度，致使動環(huán)不能補償磨耗位移，硬對硬摩擦副的運轉(zhuǎn)壽命要比硬對石墨摩擦副的長，因為固體顆粒會嵌入石墨密封環(huán)的密封面內(nèi)。對策：在固體顆粒容易進入的位置應(yīng)選用碳化鎢對碳化鎢摩擦副的機械密封。4、因其他問題引起的機械密封滲漏機械密封中還存在設(shè)計、選擇、安裝等不夠合理的地方。（1）彈簧壓縮量一定要按規(guī)定進行，不允許有過大或過小的現(xiàn)象，誤差±2mm，壓縮量過大增加端面比壓，摩擦熱量過多，造成密封面熱變形和加速端面磨損，壓縮量過小動靜環(huán)端面比壓不足，則不能密封。（2）安裝動環(huán)密封圈的軸（或軸套）端面及安裝靜環(huán)密封圈的密封壓蓋。神通博格曼機械密封件680。泉州神通博格曼機械密封件204</p><p
