水泵的機(jī)械密封亦稱端面密封,其有一對垂直于旋轉(zhuǎn)軸線的端面,該端面在流體壓力及補(bǔ)償機(jī)械外彈力的作用下,依賴輔助密封的配合與另一端保持貼合,并相對滑動(dòng),從而防止流體泄漏。 </p> <p> 一、機(jī)械密封常見的滲漏現(xiàn)象 </p> <p> 機(jī)械密封滲漏的比例占全部維修泵的50 %以上,機(jī)械密封的運(yùn)行好壞直接影響到水泵的正常運(yùn)行,現(xiàn)總結(jié)分析如下: </p> <p> 1.機(jī)械密封周期性滲漏 </p> <p> (1)防爆自吸泵轉(zhuǎn)子軸向竄動(dòng)量大,輔助密封與軸的過盈量大,動(dòng)環(huán)不能在軸上靈活移動(dòng)。在泵翻轉(zhuǎn),動(dòng)、靜環(huán)磨損后,得不到補(bǔ)償位移。 </p> <p> 對策:在裝配機(jī)械密封時(shí),軸的軸向竄動(dòng)量應(yīng)小于0，淮安機(jī)械液壓密封批發(fā)廠.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(shí),動(dòng)環(huán)裝配后保證能在軸上靈活移動(dòng)(把動(dòng)環(huán)壓向彈簧能自由地彈回來)。 </p> <p> (2)密封面潤滑油量不足引起干摩擦或拉毛密封端面。 </p> <p> 對策:油室腔內(nèi)潤滑油面高度應(yīng)加到高于動(dòng)、靜環(huán)密封面。 </p> <p> (3)轉(zhuǎn)子周期性振動(dòng)。原因是定子與上，淮安機(jī)械液壓密封批發(fā)廠，淮安機(jī)械液壓密封批發(fā)廠、下端蓋未對中或葉輪和主軸不平衡,汽蝕或軸承損壞(磨損) ,這種情況會(huì)縮短密封壽命和產(chǎn)生滲漏。 </p> <p> 對策:可根據(jù)維修標(biāo)準(zhǔn)來糾正上述問題。軸彎曲變形時(shí)橫截面形心沿與軸線垂直方向的線位移稱為撓度，機(jī)械密封要求兩個(gè)密封端面之間受力均勻?；窗矙C(jī)械液壓密封批發(fā)廠</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">橡膠是常用的密封材料。除橡膠外，適合于做密封材料的還有石墨等，聚四氟乙烯以及各種密封膠等。通用的橡膠密封制品材料通用的橡膠密封制品在**，化工，煤炭，石油，冶金，交通運(yùn)輸和機(jī)械制造產(chǎn)業(yè)等方面的應(yīng)用越來越廣為，已成為各種行業(yè)中的基礎(chǔ)件和配件。橡膠密封制品常用材料如下。丁腈橡膠丁腈橡膠具有優(yōu)良的耐燃料油及芳香溶劑等性能，但不耐酮，酯和氯化氫等介質(zhì)，因此耐油密封制品以及采用丁腈橡膠為主。氯丁橡膠氯丁橡膠具有良好的耐油和耐溶劑性能。它有較好的耐齒輪油和變壓器油性能，但不耐芳香族油。氯丁橡膠還具有優(yōu)良的耐天候老化和臭氧老化性能。氯丁橡膠的交聯(lián)斷裂溫度在200℃以上，通常用氯丁橡膠制作門窗密封條。氯丁橡膠對于無機(jī)酸也具有良好的耐腐蝕性。此外，由于氯丁橡膠還具有良好的撓曲性和不透氣性，可制成膜片和真空用的密封制品。自然橡膠自然橡膠與多數(shù)合成橡膠相比，具有良好的綜協(xié)力學(xué)性能，耐冷性，較高的回彈性及耐磨性。自然橡膠不耐礦物油，但在植物油和醇類中較穩(wěn)定。在以正丁醇與精制蓖麻油混合液體組成的制動(dòng)液的液壓制動(dòng)系統(tǒng)中作為密封件的膠碗，膠圈均用自然橡膠制造，一般密封膠也常用自然橡膠制造。江蘇工業(yè)密封廠家價(jià)格在實(shí)際安裝過程中，應(yīng)該做好對裝配圖的核對工作，并檢各種零件表面是否出現(xiàn)了劃痕、缺點(diǎn)等情況。</p><div

應(yīng)切實(shí)提高安裝工程的質(zhì)量意識(shí)，嚴(yán)格執(zhí)行安裝、檢修的制度化和標(biāo)準(zhǔn)化。以密封圈的松緊度為例，旋動(dòng)環(huán)密封圈過松會(huì)影響密封效果，但過緊也可能加劇其與軸套間的磨損，并易使旋動(dòng)環(huán)出現(xiàn)疲勞和變形;而靜止環(huán)雖然相對應(yīng)更緊一些，但過緊也會(huì)導(dǎo)致變形或出現(xiàn)脆裂，因此必須依照安裝指導(dǎo)書測量和調(diào)整，保證其壓縮量符合要求。 </p> <p> 2 機(jī)械密封使用中滲漏的預(yù)防和處理 </p> <p> 日常機(jī)械密封的管路系統(tǒng)檢查與使用，是機(jī)械密封正常運(yùn)行的保障，因此應(yīng)將設(shè)備管理的責(zé)任落實(shí)到人，制定嚴(yán)格的檢修維護(hù)制度并予以落實(shí)。檢查所有與機(jī)械密封運(yùn)行有關(guān)的閥門，保證安監(jiān)儀表完好;檢查機(jī)械密封自循環(huán)水、水泵涵體、機(jī)械密封水管路、換熱器及機(jī)械密封水的冷卻水的暢通，溫度無異常變化，發(fā)現(xiàn)問題及時(shí)查明原因，并有針對性地解決。

style="text-indent:25px">在工業(yè)生產(chǎn)中，水泵密封采用機(jī)械密封已經(jīng)成為大家的共識(shí)，其相比傳統(tǒng)的盤根填料密封，能耗低，密封性能好，使用壽命長普遍得到共同的認(rèn)可。但是，同樣是機(jī)械密封也是有區(qū)分，一些廠家為了投標(biāo)降低成本采用**代機(jī)械密封，雖然價(jià)格低廉，但是浮動(dòng)性能差、使用壽命短，同時(shí)因?yàn)榻橘|(zhì)泄漏造成的不必要停機(jī)，影響了設(shè)備連續(xù)生產(chǎn)，也給現(xiàn)場維修帶來了困擾。水泵機(jī)械密封是轉(zhuǎn)動(dòng)機(jī)械本體密封較大程度有效的方式之一，其本身加工的精度比較高，尤其是動(dòng)、靜環(huán)，如果拆裝方法不合適或使用不當(dāng)，裝配后的機(jī)械密封不但達(dá)不到密封的目的，而且會(huì)損壞集結(jié)的密封元件。機(jī)械密封拆卸時(shí)注意事項(xiàng)在拆卸機(jī)械密封時(shí)，嚴(yán)禁動(dòng)用手錘和扁鏟，以免損害密封元件。如果在泵兩端都有機(jī)械密封時(shí)，則在拆卸過程中必須小心謹(jǐn)慎，防止顧此失彼。對工作過的機(jī)械密封，如果壓蓋松動(dòng)時(shí)密封面發(fā)生移動(dòng)的情況，則應(yīng)更換動(dòng)靜環(huán)零件，不應(yīng)重新上緊繼續(xù)使用。因?yàn)樵谒蓜?dòng)后，摩擦副原來運(yùn)轉(zhuǎn)軌跡會(huì)發(fā)生改變，接觸面的密封性就很容易遭到破壞。介質(zhì)的低于飽和蒸汽壓力，使得端面液膜發(fā)生閃蒸，喪失潤滑。</p><div

化工設(shè)備機(jī)械密封失效的過程中會(huì)呈現(xiàn)一定的癥狀，其常見的癥狀可以歸納為以下幾點(diǎn)：機(jī)械設(shè)備出現(xiàn)持續(xù)性的泄漏狀況，在化工設(shè)備工作時(shí)，會(huì)出現(xiàn)尖叫等情況。其次，當(dāng)化工設(shè)備在運(yùn)行的過程中，其密封面的外側(cè)會(huì)出現(xiàn)石墨粉塵，它們會(huì)凝聚在一塊。另者，當(dāng)化工設(shè)備在運(yùn)行時(shí)，其密封處發(fā)出爆鳴聲音，這也可能會(huì)是出現(xiàn)化工設(shè)備機(jī)械密封失效。同時(shí)，如果泵以及軸一直振動(dòng)，密封的使用壽命比較短，這也有可能是因?yàn)榛ぴO(shè)備機(jī)械密封失效。當(dāng)化工設(shè)備出現(xiàn)以上情況時(shí)，相關(guān)技術(shù)人員應(yīng)該對機(jī)械密封進(jìn)行檢查，進(jìn)一步確定是否是化工設(shè)備機(jī)械密封失效，同時(shí)找出其失效的原因。
