常用墊圈性能---及新材料和新技術(shù)一)常用墊圈性能使用閥門時(shí)，往往根據(jù)具體情況，更換原帶墊圈。常有墊圈有：橡膠平墊圈、橡膠O形圈、塑料平墊圈、聚四氟乙烯包墊圈、石棉橡膠墊圈、金屬平墊圈、金屬異形墊圈、金屬包皮墊圈、波形墊圈、纏繞墊圈等。(1)橡膠平墊圈：變形容易，壓緊時(shí)不費(fèi)力，但耐壓、耐溫能力都較差，只用于壓力低、溫度不高的地方。天然橡膠有一定耐酸堿性能，使用溫度不宜超過60℃；氯丁橡膠也能耐某些酸堿，使用溫度80℃；丁腈橡膠耐油，可用至80℃；氟橡膠耐腐蝕性能很好，耐溫性能也比一般橡膠強(qiáng)，可在150℃介質(zhì)中使用。(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**大特點(diǎn)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，江蘇DG85-80連成水泵機(jī)械密封。(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(diǎn)，同時(shí)彌補(bǔ)它彈性較差的缺點(diǎn)，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，江蘇DG85-80連成水泵機(jī)械密封，增強(qiáng)密封效果，減小壓緊力，江蘇DG85-80連成水泵機(jī)械密封。其斷面形狀如圖4-20所示。。150AY67連成水泵機(jī)械密封。江蘇DG85-80連成水泵機(jī)械密封</p><div

選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。選型的基本原則為：1.根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。2.根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。3.根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。4.根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。機(jī)械密封件安裝編輯1.機(jī)械密封對機(jī)器精度的要求（以泵用機(jī)械密封為例）（1）安裝機(jī)械密封部位的軸（或軸套）的徑向跳動公差**大不超過～。（2）轉(zhuǎn)子軸向竄動不超過。（3）密封腔體與密封端蓋結(jié)合的定位端面對軸（或軸套）表面的跳動公差**大不超過～。2.密封件的確認(rèn)（1）確認(rèn)所安裝的密封是否與要求的型號一致。(2)安裝前要仔細(xì)地與總裝圖對照，零件數(shù)量是否齊全。(3)并圈彈簧傳動的機(jī)械密封，其彈簧有左、右旋之分，須按轉(zhuǎn)軸的旋向來選擇。3：安裝安裝方法隨機(jī)械密封型式、機(jī)器的種類不同而有所不同，但其安裝要領(lǐng)幾乎都相同，安裝步驟和注意事項(xiàng)如下：(1)安裝尺寸的確定安裝時(shí)。</p><p> 軸套）磨擦部位產(chǎn)生結(jié)晶物，在彈簧處也會存有固體物質(zhì)，都會使密封面打開。2過熱因密封面上會產(chǎn)生熱，故橡膠圈使用溫度應(yīng)低于設(shè)計(jì)規(guī)范。氟橡膠和聚四氟乙烯的使用溫度為216℃，丁晴橡膠的使用溫度為162℃，雖然它們都能承受較高的溫度，但因密封面產(chǎn)生的熱較高，所以橡膠圈有繼續(xù)硫化的危險(xiǎn)，**終失去彈性而泄漏。（冷區(qū)考慮冷脆）密封面之間還會因熱引起介質(zhì)的結(jié)晶，如結(jié)碳，造成滑動部件被粘住和密封面被凝結(jié)。而且有些聚合物因過熱而焦化，有些流體因過熱而失去潤滑等甚至閃火。過熱除能改變介質(zhì)的狀況外，還會加劇它的腐蝕速率。引起金屬零件的變形，合金面的開裂，以及某些鍍層裂縫，設(shè)計(jì)應(yīng)選用平衡型機(jī)械密封，以降低比壓防止過熱。3超差正確的裝配公差，對于安裝機(jī)械密封是很必要的，軸（軸套）必須有合適的表面粗糙度和正確的尺寸，但制造者很少提供公差數(shù)據(jù)，這些數(shù)據(jù)對安裝來講都是很關(guān)鍵的。（依靠經(jīng)驗(yàn)和常識）機(jī)械密封的尺寸精度及形位公差必須符合圖紙要求，超差將會導(dǎo)致密封提前失效。（二）密封失效原因分析密封面本身也會提供密封失效的跡象，如振動時(shí)，在傳動零件上就會有磨損的痕跡，如痕跡不明顯，則一般是裝配不當(dāng)造成的。對于質(zhì)量較差的石墨環(huán)。山西連成水泵機(jī)械密封。</p><div

1.沖洗方案01方案：從泵的出口端沖洗內(nèi)機(jī)械密封腔。操作類似方案PLAN11原因:密封腔冷卻，臥式泵的密封腔排氣，防止PLAN11方案外露管的凍結(jié)和流體結(jié)晶堵塞的危險(xiǎn)場合：普通密封腔，**可能是ANSI/ASME泵，清潔常溫流體，用于單端面密封，很少用于雙斷面密封。維護(hù)：沖洗不能直接沖洗密封面，機(jī)封冷卻不能過度，根據(jù)通過內(nèi)截流管的揚(yáng)程損失計(jì)算沖洗流量。2.沖洗方案02方案：無沖洗的封閉密封腔。原因：不需要流體二次循環(huán)。使用場合：常溫運(yùn)轉(zhuǎn)下的大孔/開口密封腔，高溫運(yùn)轉(zhuǎn)下的冷卻套密封腔，清潔流體，干式密封的直立/頂入式混和器/攪拌器，維護(hù)：流程必須有足夠的沸點(diǎn)臨界空間，避免汽化，在熱運(yùn)轉(zhuǎn)條件下，密封腔套內(nèi)可能需要一直有冷卻液體，臥式設(shè)備必能自己排氣，經(jīng)常和冷卻方案PLAN62聯(lián)合使用。3.沖洗方案11方案：從泵出口處經(jīng)過限流孔板進(jìn)行機(jī)械密封沖洗，違反單端面機(jī)械密封沖洗方案。原因：密封腔的冷卻，臥式密封腔的排氣，增加密封腔的壓力和流體汽化臨界空間。場合：通常用于清潔流體，清潔、非聚合流體。維護(hù)：使用孔徑**小為，計(jì)算流量以確定使機(jī)封腔流量足夠的限流孔板尺寸，通過合適的限流孔板和喉部襯套尺寸來確定增加沸點(diǎn)臨界范圍。甘肅連成水泵機(jī)械密封。江蘇DG85-80連成水泵機(jī)械密封</p><p
