吸沙泵上配置的機(jī)械密封是一種旋轉(zhuǎn)機(jī)械的軸封裝置。機(jī)械密封具有泄漏量少和壽命長(zhǎng)等優(yōu)點(diǎn)，所以離心式吸沙泵上的密封形式有時(shí)會(huì)選用機(jī)械密封。機(jī)械密封又叫端面密封，是由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置。離心式吸沙泵在安裝機(jī)械密封時(shí)應(yīng)注意安裝的方式，以免出現(xiàn)偏差，起不到密封的作用，甚至對(duì)機(jī)封造成損壞。首先要十分注意避免安裝中所產(chǎn)生的安裝偏差，同心度不找齊的話很容易產(chǎn)生縫隙，各個(gè)接觸點(diǎn)的誤差不能大于。其次彈簧壓縮量要按規(guī)定進(jìn)行，不允許有過(guò)大或過(guò)小現(xiàn)象，要求誤差。過(guò)大會(huì)增加端面比壓，加速端面磨損。過(guò)小會(huì)造成比壓不足而不能起到密封作用。動(dòng)環(huán)安裝后，將動(dòng)環(huán)壓向彈簧后應(yīng)能自動(dòng)彈回來(lái)。為了保證機(jī)械密封穩(wěn)定的運(yùn)行、長(zhǎng)壽命和低泄漏性能，將它正確地安裝在吸沙泵上是十分重要的。首先是安裝部件的確認(rèn)。把機(jī)械密封安裝到吸沙泵上時(shí)，安裝前要很好的與總裝配圖相對(duì)照，確認(rèn)零件是否已準(zhǔn)備齊全，要注意與填料、密封圈（O環(huán)）等相接觸的軸或軸套表面、法蘭等部件上有無(wú)傷痕，若發(fā)現(xiàn)有異常的現(xiàn)象，則必須更換或修理后再使用。濱海新區(qū)CR3格蘭富機(jī)械密封江西格蘭富機(jī)械密封大全。</p><div

機(jī)械密封對(duì)泵輸送的影響隨著科學(xué)技術(shù)和生產(chǎn)的發(fā)展，流體機(jī)械和流體工程的應(yīng)用范圍不斷擴(kuò)大，而泵用高溫密封、紙溫密封、**溫、強(qiáng)腐蝕、易燃、易爆、有毒、放射性介質(zhì)、泵高壓密封、泵用高真空密封以及含各種雜質(zhì)等懸浮顆粒介質(zhì)的泵用密封也都應(yīng)運(yùn)而生。保證密封的可靠性和使用壽命，是當(dāng)前泵用密封研究、設(shè)計(jì)制造、使用等各方面**重要的課題之一。泵高溫機(jī)械密封密封的功能是阻止泄漏。起密封作用的零部件稱為密封件，簡(jiǎn)稱為密封。較復(fù)雜的密封，尤其是帶有附屬系統(tǒng)的，則稱為密封裝置。流體密封包括流體靜密封和流體動(dòng)密封。相對(duì)靜止結(jié)合面（即密封面）間的密封稱為靜密封；相對(duì)運(yùn)動(dòng)的結(jié)合面的密封稱為動(dòng)密封。對(duì)流體機(jī)械和流體工程而言，密封是不可缺少的零部件，在眾多機(jī)器設(shè)備中，雖然密封一般只占整個(gè)機(jī)器較小的比重，但往往直接決定了整臺(tái)甚至整套設(shè)備的安全性、可靠性和耐久性。從而成為評(píng)價(jià)諸多機(jī)械產(chǎn)品質(zhì)量的一個(gè)重要指標(biāo)。尤其在石化等工業(yè)中，輸送、處理和儲(chǔ)存的流體許多是具有易燃、易爆、腐蝕和有毒類的介質(zhì)，一旦密封出現(xiàn)故障，甚至失效現(xiàn)象，后果是嚴(yán)重的，輕則影響產(chǎn)品質(zhì)量、污染環(huán)境，危及周圍人員的健康。</p><p> 可能會(huì)使機(jī)械密封的輔助密封圈發(fā)生老化、泡脹等情況,造成了機(jī)械密封的泄漏。所以在高溫、酸性或者堿性的工作環(huán)境中,機(jī)械密封的輔助密封圈所用的橡膠材質(zhì)應(yīng)選擇那種能耐高溫、耐酸堿的氟橡膠。第三,細(xì)小顆粒物雜質(zhì)損壞密封面引起泄漏當(dāng)彈性元件失彈,動(dòng)環(huán)得不到軸向補(bǔ)償?shù)臅r(shí)候,細(xì)小顆粒物雜質(zhì)會(huì)隨著工作介質(zhì)進(jìn)入到密封端面間,這會(huì)劃傷或者加快磨損密封面,破壞兩密封端面之間的緊密貼合程度,從而使機(jī)械密封岀現(xiàn)泄漏。對(duì)于這種情況可選用硬對(duì)硬的摩擦副材質(zhì),比如碳化硅對(duì)硬質(zhì)合金的摩擦副。3.現(xiàn)場(chǎng)操作人員的經(jīng)驗(yàn)不足臥式高溫離心泵安裝時(shí)一定要嚴(yán)格按照國(guó)家標(biāo)準(zhǔn),盡量避免因?yàn)榘惭b原因?qū)е碌臋C(jī)械密封失效。高溫高壓多級(jí)泵運(yùn)行過(guò)程中出現(xiàn)的泄漏泵用機(jī)械密封在靜試后,高溫高壓多級(jí)離心泵運(yùn)行時(shí)產(chǎn)生的離心力會(huì)阻礙介質(zhì)的泄漏。所以運(yùn)行時(shí)的機(jī)封泄漏大多是因?yàn)閯?dòng)靜環(huán)摩擦副磨損所導(dǎo)致的。造成的原因有以下幾點(diǎn):現(xiàn)場(chǎng)操作人員缺乏經(jīng)驗(yàn)、操作不正當(dāng)造成摩擦面分離;第二,安裝時(shí)過(guò)緊,導(dǎo)致摩擦面磨損；第三,如果動(dòng)環(huán)密封圈過(guò)緊會(huì)造成彈簧無(wú)法調(diào)整；第四,介質(zhì)不干凈,有顆粒物進(jìn)入摩擦副,造成動(dòng)靜環(huán)磨損。臥式高溫離心泵機(jī)封泄漏改造方案：針對(duì)故障原因,對(duì)多級(jí)泵泵口環(huán)及節(jié)流套進(jìn)行改造將。CR32格蘭富機(jī)械密封。</p><div

把動(dòng)環(huán)壓向彈簧能自由地彈回來(lái)）。（2）密封面潤(rùn)滑油量不足引起干摩擦或拉毛密封端面。對(duì)策：油室腔內(nèi)潤(rùn)滑油面高度應(yīng)加到高于動(dòng)、靜環(huán)密封面。（3）轉(zhuǎn)子周期性振動(dòng)。原因是定子與上、下端蓋未對(duì)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。對(duì)策：可根據(jù)維修標(biāo)準(zhǔn)來(lái)糾正上述問(wèn)題。2、由于壓力產(chǎn)生的滲漏（1）高壓和壓力波造成的機(jī)械密封滲漏由于彈簧比壓力及總比壓設(shè)計(jì)過(guò)大和密封腔內(nèi)壓力超過(guò)3MPa時(shí)，會(huì)使密封端面比壓過(guò)大，液膜難以形成，密封端面磨損嚴(yán)重，發(fā)熱量增多，造成密封面熱變形。對(duì)策：在裝配機(jī)封時(shí)，彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過(guò)大或過(guò)小的現(xiàn)象，高壓條件下的機(jī)械密封應(yīng)采取措施。為使端面受力合理，盡量減小變形，可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料，并加強(qiáng)冷卻的潤(rùn)滑措施。（2）真空狀態(tài)運(yùn)行造成的機(jī)械密封滲漏泵在起動(dòng)、停機(jī)過(guò)程中，由于泵進(jìn)口堵塞，抽送介質(zhì)中含有氣體等原因，有可能使密封腔出現(xiàn)負(fù)壓，密封腔內(nèi)若是負(fù)壓，會(huì)引起密封端面干摩擦，內(nèi)裝式機(jī)械密封會(huì)產(chǎn)生漏氣（水）現(xiàn)象，真空密封與正壓密封的不同點(diǎn)在于密封對(duì)象的方向性差異，而且機(jī)械密封也有其某一方向的適應(yīng)性。格蘭富機(jī)械密封CR15-4。濱海新區(qū)CR3格蘭富機(jī)械密封</p><p
