新的密封形式和密封材料陸續(xù)出現(xiàn)，其必然對泵的密封技術(shù)產(chǎn)生直接的影響和推動。長壽命、零泄漏的泵類產(chǎn)品會在越來越多的場合得到推廣和應(yīng)用。油封密封油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場合。油封應(yīng)安裝在制造精度為h8～h9，表面粗糙度為～μm且經(jīng)過表面硬化處理的軸上。密封介質(zhì)不應(yīng)含有固體微粒和雜質(zhì)，否則會造成油封和軸的迅速磨損而使密封失效。墊片密封墊片是離心泵靜密封的基本元件，使用范圍非常廣。墊片的選型主要根據(jù)泵輸送介質(zhì)、溫度、壓力和腐蝕性等因素決定。當(dāng)溫度和壓力不高時一般選用非金屬密封墊片;中壓高溫時，選用非金屬與金屬組合墊片。非金屬墊片在泵上應(yīng)用普遍，其材料一般為紙、橡膠和聚四氟乙烯。當(dāng)溫度不超過120℃，壓力在，一般選用青殼紙或模造紙墊片。如果輸送介質(zhì)為油，溫度在-30～110℃時(公眾號:泵管家)，一般選用耐老化性能較好的丁晴橡膠。當(dāng)輸送介質(zhì)在-50～200℃時，選用氟橡膠更為合適。因為它除了耐油耐熱外，機(jī)械強(qiáng)度大也是其主要特征。在化工泵中。</p><p> 原來平口環(huán)結(jié)構(gòu)改造為迷宮油封,既能有效阻止介質(zhì)中的硬顆粒進(jìn)入口環(huán)摩擦副對配合面進(jìn)行腐蝕,增加泄漏阻力提高泵的使用性能,也能防止口環(huán)配合面咬合抱死。具體來講:相對于平口環(huán)結(jié)構(gòu),在與主軸保持相同的配合間隙下,迷宮口環(huán)由于在旋轉(zhuǎn)軸周圍依次排列著許多環(huán)形密封齒,介質(zhì)在迷宮中流動時,具有更大的摩阻效應(yīng),使得流速更慢,流量更少,因此泵的泄漏損失更少,效率更高。將多級泵的口環(huán)設(shè)計成迷宮口環(huán)后,因葉輪口環(huán)與泵體口環(huán)之間的接觸面積變小,且迷宮齒之間有一定的空間,因此介質(zhì)的硬質(zhì)顆粒進(jìn)入口環(huán)后能夠在迷宮齒之間的空間停留,減小了轉(zhuǎn)子與泵體口環(huán)咬合抱死的概率。由于加工迷宮齒,需將原泵體口環(huán)的分半形式改造為整體形式,以便保證加工精度,改造后雖拆裝口環(huán)時需要逐級拆卸葉輪,拆除工作量增加,但是整體口環(huán)結(jié)構(gòu)可增強(qiáng)摩擦副配合的準(zhǔn)確性與加工精度,使泵的運行更加穩(wěn)定可靠。安徽格蘭富機(jī)械密封件。</p><div

對策：采用雙端面機(jī)械密封，這樣有助于改善潤滑條件，提高密封性能。3、由于介質(zhì)引起的滲漏（1）大多數(shù)潛污泵機(jī)械密封拆解后，靜環(huán)和動環(huán)的輔助密封件無彈性，有的已經(jīng)腐爛，造成了機(jī)封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對靜環(huán)和動環(huán)輔助橡膠密封件的腐蝕作用，造成了機(jī)械滲漏過大，動、靜環(huán)橡膠密封圈材料為丁腈—40，不耐高溫，不耐酸堿，當(dāng)污水為酸性堿性時易腐蝕。對策：對腐蝕性介質(zhì)，橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。（2）固體顆粒雜質(zhì)引起的機(jī)械密封滲漏如果固體顆粒進(jìn)入密封端面，將會劃傷或加快密封端面的磨損，水垢和油污在軸（套）表面的堆積速度超過摩擦副的磨損速度，致使動環(huán)不能補(bǔ)償磨耗位移，硬對硬摩擦副的運轉(zhuǎn)壽命要比硬對石墨摩擦副的長，因為固體顆粒會嵌入石墨密封環(huán)的密封面內(nèi)。對策：在固體顆粒容易進(jìn)入的位置應(yīng)選用碳化鎢對碳化鎢摩擦副的機(jī)械密封。4、因其他問題引起的機(jī)械密封滲漏機(jī)械密封中還存在設(shè)計、選擇、安裝等不夠合理的地方。（1）彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象，誤差±2mm，壓縮量過大增加端面比壓，摩擦熱量過多，造成密封面熱變形和加速端面磨損。格蘭富機(jī)械密封CR90-6。天津格蘭富機(jī)械密封配件廠</p><p

應(yīng)避免發(fā)生抽空現(xiàn)象，以免造成密封面干摩擦及密封破壞。4、密封情況要經(jīng)常檢查。運轉(zhuǎn)中，當(dāng)其泄漏超過標(biāo)準(zhǔn)時，如2-3日內(nèi)仍無好轉(zhuǎn)趨勢，則應(yīng)停泵檢查密封裝置。吸沙泵配置機(jī)械密封的優(yōu)點是密封性好，但機(jī)械密封的造價成本高，更換不方便也是現(xiàn)實操作中存在的問題。機(jī)械密封一旦發(fā)生損壞，維修成本要比填料密封高出不少。因為在安裝使用時應(yīng)格外注意。減少不必要的操作。避免損害機(jī)封。海川泵業(yè)專業(yè)從事吸沙泵、抽沙泵、泥漿泵、混流泵等設(shè)備研發(fā)、生產(chǎn)和銷售。特別是在清淤、采沙、固堤方面，有著豐富的經(jīng)驗。我們專注吸沙泵20年，不僅提供高質(zhì)量的產(chǎn)品和行業(yè)整體解決方案，還提供現(xiàn)場安裝服務(wù)，有關(guān)清淤、吸沙方面方案設(shè)計及設(shè)備問題請隨時聯(lián)系我們。濱州格蘭富機(jī)械密封NBG100-80-160/173A-F-N-BBQE</p></p><br
