水泵的機(jī)械密封亦稱端面密封,其有一對(duì)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(duì)滑動(dòng),從而防止流體泄漏。 </p> <p> 一、機(jī)械密封常見(jiàn)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(guò)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(duì)策:在裝配機(jī)械密封時(shí),軸的軸向竄動(dòng)量應(yīng)小于0.1mm ,輔助密封與軸的過(guò)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(lái))。 </p> <p> (2)密封面潤(rùn)滑油量不足引起干摩擦或拉毛密封端面。 </p> <p> 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。 </p> <p> (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，江蘇中型機(jī)械密封廠家供應(yīng)，江蘇中型機(jī)械密封廠家供應(yīng)。 </p> <p> 對(duì)策:可根據(jù)維修標(biāo)準(zhǔn)來(lái)糾正上述問(wèn)題，江蘇中型機(jī)械密封廠家供應(yīng)。機(jī)械密封的密封面要有一定的比壓，從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過(guò)彈簧調(diào)節(jié)。江蘇中型機(jī)械密封廠家供應(yīng)</p><div

工程機(jī)械密封圈是解決轉(zhuǎn)軸與閥體之間密封的一種裝置。它是一種防止流體泄漏的裝置，它由至少一對(duì)垂直于旋轉(zhuǎn)軸端面的流體壓力和補(bǔ)償機(jī)構(gòu)的彈性力(或磁力)的作用以及輔助密封的作用來(lái)防止流體泄漏。它常用于泵、壓縮機(jī)、反應(yīng)攪拌釜和其他旋轉(zhuǎn)流體機(jī)械，以及變速箱、船舶尾軸等。因此，機(jī)械密封是一種通用的軸封裝置。 </p> <p> 機(jī)械密封結(jié)構(gòu)有很多種，**常用的機(jī)械密封結(jié)構(gòu)是端面密封。端面密封的靜環(huán)和動(dòng)環(huán)形成一對(duì)摩擦副，其作用是防止介質(zhì)泄漏。它要求靜環(huán)、動(dòng)環(huán)具有良好的耐磨性，運(yùn)動(dòng)環(huán)可在軸向靈活運(yùn)動(dòng)，自動(dòng)補(bǔ)償密封表面的磨損，使其與靜態(tài)環(huán)很好地匹配，靜環(huán)具有浮性，起到緩沖作用。因此，密封表面要求良好的加工質(zhì)量，以保證密封副具有良好的粘接性能。機(jī)械密封的基本部件有靜環(huán)、動(dòng)環(huán)、壓力罩、推環(huán)、彈簧、定位環(huán)、軸套、動(dòng)環(huán)密封圈、靜環(huán)密封環(huán)、軸套密封環(huán)等。南京中型機(jī)械密封供貨商建議對(duì)橡膠制品儲(chǔ)存環(huán)境：環(huán)境溫度不超過(guò)120。F（49℃）；避光（特別是太陽(yáng)光）存放。</p><div

style="text-indent:25px">HG20592~20635-1997規(guī)定采用非金屬墊密封時(shí)，法蘭密封面可車制密紋水線或要求法蘭密封面表面粗糙度。對(duì)于突面法蘭如車制密紋水線，則標(biāo)記為“RF（A）”。小編也曾在現(xiàn)場(chǎng)開(kāi)箱驗(yàn)收時(shí)，遇到安裝公司驗(yàn)收人員發(fā)現(xiàn)法蘭密封面不光滑提出疑問(wèn)。那么，法蘭密封面必須車制密紋水線嗎？在工廠制造法蘭時(shí)一般都在密封面上均勻的車2-3道，水線一般是深1mm，90度,寬度在5mm，密封水紋線的加工，有利于法蘭的密封，而且制造上也容易實(shí)現(xiàn)。但這種密紋水線一般用在軟墊片上。由于墊片是軟的，法蘭面通過(guò)擠壓，使墊片進(jìn)入到這些線中，起到密封的作用。密紋水線的加入，把一個(gè)密封面分成了好幾個(gè)密封面，水線好比迷宮，減少了介質(zhì)泄露的可能。新的標(biāo)準(zhǔn)取消了密紋水線的要求，在HG/T20592~20635-2009中規(guī)定，突面、凹面/凸面及全平面密封面是采用加工車刀加工時(shí)自然形成的一種鋸齒形同心圓或螺旋齒槽。加工車刀的圓角半徑應(yīng)不小于，形成的鋸齒形同心圓或螺旋齒槽深度約為，節(jié)距約為。這樣也起到了增加密封效果的作用，只不過(guò)紋線是加工時(shí)自然出現(xiàn)的細(xì)密紋線，而水線則是單獨(dú)加工出來(lái)的2道或3道較深的槽，而且密紋水線不能是螺旋線。</p><p> 油封 </p> <p> 油封，即潤(rùn)滑油的密封。它常用于各種機(jī)械的軸承處，特別是轉(zhuǎn)動(dòng)軸承部位。其功能在于把油腔和外界隔離，對(duì)內(nèi)封油，對(duì)外封塵。 </p> <p> 油封與其他密封比較有下列優(yōu)點(diǎn)： </p> <p> 油封重量輕，耗材少。 </p> <p> 油封的安裝位置小，軸向尺寸小，輕易加工。 </p> <p> 密封性能好，使用壽命較長(zhǎng)，對(duì)機(jī)器的振動(dòng)和主軸的偏心都有一定的適應(yīng)性。 </p> <p> 拆卸輕易，檢驗(yàn)方便。 </p> <p> 價(jià)格便宜。 </p> <p> 防塵密封 </p> <p> 油封可作防塵密封件的使用。但是在粉塵嚴(yán)重或是為了保護(hù)其他密封件時(shí)，經(jīng)常使用專門(mén)的防塵密封。 </p> <p> 防塵密封的材料，油壓機(jī)械多用橡膠，氣壓機(jī)械多用毛氈，飛機(jī)和冷帶工作的油缸為了對(duì)付活塞桿外部結(jié)冰而用金屬，化工部分為防止活塞桿上的粘著物也用金屬。 </p> <p> 防塵密封對(duì)保護(hù)關(guān)鍵性的液壓設(shè)備是十分重要的。滲透塵土，不僅磨損密封件，而且會(huì)很大程度上的磨損導(dǎo)向套和活塞桿。此外，雜質(zhì)進(jìn)進(jìn)液壓介質(zhì)中，也會(huì)影響操縱閥和泵的功能，在壞的情況下，也可能損壞這些裝置。防塵圈能除掉活塞桿表面上的塵土和雜物，但損壞活塞桿上的油膜，這對(duì)密封件的潤(rùn)滑也有一定作用。維持摩擦面間的液膜是保證機(jī)械密封穩(wěn)定運(yùn)轉(zhuǎn)、延長(zhǎng)使用壽命所必不可少的。</p><div

迷宮效應(yīng)：軸在微觀下表面非常的不平整，與盤(pán)根只能部分貼合，而部分未接觸，所以在盤(pán)根和軸之間著微小的間隙，像迷宮一樣，帶壓介質(zhì)在間隙中多次被節(jié)流，從而達(dá)到密封的作用。 </p> <p> 軸承效應(yīng)：在盤(pán)根填料和軸之間會(huì)存在著一層薄薄液膜，使盤(pán)根填料和軸類似于滑動(dòng)軸承，起到了一定的潤(rùn)滑作用，從而避免了盤(pán)根和軸的過(guò)度磨損。 </p> <p> 盤(pán)根填料對(duì)材料的要求 </p> <p> 由于受密封介質(zhì)的溫度、壓力、PH，以及設(shè)備的線速度、表面粗糙度、同軸度、徑跳、偏心等因素，就要求盤(pán)根材料具有以下特點(diǎn)： </p> <p> 1、有一定的彈塑性 </p> <p> 2、化學(xué)穩(wěn)定性 </p> <p> 3、不滲透性 </p> <p> 4、自潤(rùn)滑性 </p> <p> 5、耐溫性 </p> <p> 6、拆裝方便 </p> <p> 7、制造簡(jiǎn)單，價(jià)格低廉。 </p> <p> 上述材料特性直接影響著盤(pán)根填料的密封性能和使用壽命，而能完全符合上述所有性能的材料很少，所以獲取質(zhì)量的密封材料和提高其材料性能，一直是密封領(lǐng)域研究的重點(diǎn)。 </p> </p> <p> <br />
