機(jī)械密封在電廠(chǎng)水泵中的應(yīng)用改造 </p> <p> <p> 在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤(pán)根密封形成了鮮明的對(duì)比：（1）機(jī)械密封與盤(pán)根密封在密封性能上，機(jī)械密封要比盤(pán)根密封漏泄量小的多，*為盤(pán)根密封漏泄量的1%。（2）使用壽命長(zhǎng)，兩年以?xún)?nèi)無(wú)需更換，以往盤(pán)根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤(pán)根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過(guò)摸索對(duì)比先后將車(chē)間的兩臺(tái)循環(huán)水泵、兩臺(tái)射水泵、凝結(jié)水泵共6臺(tái)泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機(jī)械密封前，每年至少要更換4次油盤(pán)根，南京水泵密封批發(fā)價(jià)，每次更換量在1公斤左右，南京水泵密封批發(fā)價(jià)，市場(chǎng)價(jià)格30元.，由于盤(pán)根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費(fèi)用在7000元左右，不計(jì)人工費(fèi)用每臺(tái)水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺(tái)泵的機(jī)械密封價(jià)格在600元左右，至少一個(gè)大修期在3年以上，由于摩擦阻力的降低使電耗每小時(shí)下降8度，全年節(jié)電在58000度，南京水泵密封批發(fā)價(jià)，降低成本3萬(wàn)元左右。因此機(jī)械密封于盤(pán)根密封相比優(yōu)勢(shì)十分明顯。 </p> <p> <br /> </p> <p> <br /> </p> 在對(duì)該設(shè)備進(jìn)行維護(hù)的過(guò)程中，也應(yīng)明確彈簧的旋向，一旦出現(xiàn)安裝錯(cuò)誤，將很容易造成泄漏問(wèn)題。南京水泵密封批發(fā)價(jià)</p><div style="width:100%;text-align: center;"><img

采用雙重密封面的密封來(lái)代替單一的密封件具有更高程度的防漏特性。這類(lèi)雙重密封大都應(yīng)用于揮發(fā)性強(qiáng)、危險(xiǎn)和潤(rùn)滑性很差的液體。 </p> <p> <span style="font-size:12px;"> 雙重密封一般有三種設(shè)計(jì)型式，每種型式都要求在雙重密封面之間使用一種液體阻隔系統(tǒng)，以防止液體或氣體外泄。比較常用的低成本雙重密封是一種以背靠背方式安裝的密封，其旋轉(zhuǎn)密封面以相反的方向排列。它往往需要一種阻隔液體，其壓力應(yīng)高于填料盒壓力，大約為20psi，這樣就可保證內(nèi)部的密封始終能得到阻隔液體的潤(rùn)滑，而且也可保證密封面達(dá)到一定的密封壓力。</span> 南京容積泵密封廠(chǎng)家批發(fā)根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及選擇潤(rùn)滑、沖洗、保溫、冷卻機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="font-size:12px;">安裝機(jī)械密封部位的軸（或軸套）的徑向跳動(dòng)公差比較大不超過(guò)0.04～0.06mm。</span> </p> <p> 轉(zhuǎn)子軸向竄動(dòng)不超過(guò)0.3mm。 </p> <p> <span style="font-size:12px;">密封腔體與密封端蓋結(jié)合的定位端面對(duì)軸（或軸套）表面的跳動(dòng)公差比較大不超過(guò)0.04～0.06mm。</span> </p> <p> <span style="font-size:12px;"> 密封件的確認(rèn)</span> </p> <p> 確認(rèn)所安裝的密封是否與要求的型號(hào)一致。 </p> <p> 安裝前要仔細(xì)地與總裝圖對(duì)照，零件數(shù)量是否齊全。 </p> <p> 采用并圈彈簧傳動(dòng)的機(jī)械密封，其彈簧有左、右旋之分，須按轉(zhuǎn)軸的旋向來(lái)選擇。 </p> <p> <span style="font-size:12px;"> 安裝</span> </p> <p> 安裝方法隨機(jī)械密封型式、機(jī)器的種類(lèi)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： </p> <p> <span style="font-size:12px;">安裝尺寸的確定</span> </p> <p> 安裝時(shí)，應(yīng)按產(chǎn)品的使用說(shuō)明書(shū)或樣本，保證機(jī)械密封的安裝尺寸。 </p> <p> <span style="font-size:12px;">裝入前，軸（軸套）、壓蓋應(yīng)無(wú)毛刺，軸承狀況良好；密封件、軸、密封腔、壓蓋都應(yīng)該清洗干凈。</span> </p> <p> 為減少摩擦阻力，軸上安裝機(jī)械密封的部位要薄薄地涂上一層油，以進(jìn)行潤(rùn)滑，考慮到橡膠O形圈的相溶性，若不宜用油，可涂肥皂水。浮裝式靜環(huán)不帶防轉(zhuǎn)銷(xiāo)的結(jié)構(gòu)，不宜涂油，應(yīng)干式裝入壓蓋。 </p> <p> <span style="font-size:12px;">先將靜環(huán)與壓蓋一起裝在軸上，注意不要與軸相碰，然后將動(dòng)環(huán)組件裝入。彈簧座或傳動(dòng)座的緊定螺釘應(yīng)分幾次均勻擰緊。</span> </p> <p> 在未固定壓蓋之前，用手推補(bǔ)償環(huán)作軸向壓縮，松開(kāi)后補(bǔ)償環(huán)能自動(dòng)彈回?zé)o卡滯現(xiàn)象，然后將壓蓋螺拴均勻地鎖緊。 </p><p> 機(jī)械密封動(dòng)、靜環(huán)之間的工作情況，大多數(shù)是處在邊界潤(rùn)滑和半液體潤(rùn)滑狀態(tài)下，而半液體潤(rùn)滑能夠在摩擦系數(shù)較小即磨損與發(fā)熱令人滿(mǎn)意的情況下，獲得好的密封效果。 </p> <p> 機(jī)械密封的動(dòng)、靜環(huán)之間的摩擦情況： </p> <p> 半液體潤(rùn)滑： </p> <p> 滑動(dòng)表面的凹坑處存有液體，接觸面之間維持一層很薄的液膜，所以發(fā)熱和磨損情況均較好，由于動(dòng)、靜環(huán)之間的液膜在其出口處有表面張力，故限制了液體的泄露。 </p> <p> 完全液體潤(rùn)滑： </p> <p> 但由于在這種情況下動(dòng)、靜環(huán)之間的縫隙較大，故起不到密封作用，泄露嚴(yán)重。當(dāng)動(dòng)、靜環(huán)之間的壓力不足，而使間隙增大時(shí)，液膜增厚，這時(shí)不存在固體接觸，故無(wú)摩擦現(xiàn)象。在實(shí)際應(yīng)用中一般不允許有這種情況出現(xiàn)（受控膜機(jī)械密封除外）。 </p> <p> 干摩擦： </p> <p> 滑動(dòng)摩擦面上無(wú)液體進(jìn)入，因而無(wú)液膜存在，塵土和氧化層，以及吸附的氣體分子等。當(dāng)動(dòng)、靜環(huán)運(yùn)轉(zhuǎn)時(shí)，其結(jié)果必然是使摩擦面發(fā)熱、磨損加劇而造成泄露。、邊界潤(rùn)滑： </p> <p> 由于表面不是特別平的，而是凹凸不平，在凸出會(huì)有接觸磨損，而在凹處則保持液體的潤(rùn)滑性能，造成邊界潤(rùn)滑。當(dāng)動(dòng)、靜環(huán)之間的壓力增大或者液體在摩擦面上形成液膜的能力較差時(shí)，液體將從間隙中被擠出。邊界潤(rùn)滑的磨損和發(fā)熱程度為中等。針對(duì)密封實(shí)際應(yīng)用中出現(xiàn)的問(wèn)題，應(yīng)引起重視，分析問(wèn)題發(fā)生的原因，然后及時(shí)采取針對(duì)性的措施，保證效果。</p><div

有害介質(zhì)時(shí)為了取得更好的密封效果，采用雙重密封，根據(jù)密封液系統(tǒng)壓力可分為有壓雙封(雙端面機(jī)械密封)和無(wú)壓雙封(串聯(lián)式機(jī)械密封)。 </p> <p> 有壓雙封密封液系統(tǒng)的壓力一般要比一級(jí)密封前的壓力高0.01-0.03MPa。這樣一級(jí)密封泄漏時(shí)，密封液會(huì)進(jìn)入泵內(nèi)，確保了泵內(nèi)介質(zhì)不會(huì)泄漏到外界。由于密封液進(jìn)入泵內(nèi)，密封液系統(tǒng)壓力、液位降低，可以實(shí)現(xiàn)密封的泄漏監(jiān)測(cè)和報(bào)警。 </p> <p> 無(wú)壓雙封密封系統(tǒng)內(nèi)的壓力一般為常壓或微壓，低于一級(jí)密封前的密封腔壓力。當(dāng)一級(jí)密封泄漏時(shí)，泵內(nèi)介質(zhì)會(huì)進(jìn)人密封液系統(tǒng)，導(dǎo)致密封液系統(tǒng)的壓力和液位升高，可以通過(guò)壓力開(kāi)關(guān)或液位開(kāi)關(guān)實(shí)現(xiàn)泄露監(jiān)測(cè)和報(bào)警。通過(guò)密封液系統(tǒng)來(lái)監(jiān)測(cè)雙端面機(jī)械密封失效與否，也是其區(qū)別于單端面機(jī)械密封**主要的形式之一。
