丁腈橡膠適用于石油類(lèi)產(chǎn)品，如石油、潤(rùn)滑油、燃料油等，長(zhǎng)期使用溫度為120℃，如在熱油中可耐150℃，低溫為-10~-20℃。 </p> <p> 氯丁橡膠適用于海水、弱酸、弱堿、鹽溶液，耐氧和臭氧老化性能優(yōu)異，耐油性次于丁腈橡膠而優(yōu)于其他通用橡膠，長(zhǎng)期使用溫度低于90℃，比較高使用溫度不超過(guò)130℃，低溫為-30~-50℃。 </p> <p>

可能的原因:密封液在密封界面汽化加強(qiáng)密封面的冷卻 </p> <p> 解決方法:增加旁路沖洗管線（如果沒(méi)有的話）擴(kuò)大旁路沖洗管線和/或壓蓋上的開(kāi)孔。 </p> <p> 現(xiàn)象:密封連續(xù)滴漏 </p> <p> 可能的原因:表面不平;石墨密封面起泡;密封面產(chǎn)生熱變形 </p> <p> 解決方法:在安裝過(guò)程中，輔助密封被劃傷O形圈老化，由于壓縮形變輔助密封變硬變脆由于化學(xué)作用輔助密封變軟變粘 </p> <p> 現(xiàn)象:彈簧失效 </p> <p> 可能的原因:由于腐蝕作用，金屬附件損壞，傳動(dòng)機(jī)構(gòu)被腐蝕 </p> <p> 解決方法:檢查不正確的安裝尺寸,檢查是否采用了不合適的材料和密封類(lèi)型改進(jìn)沖洗冷卻管線,檢查是否出現(xiàn)壓蓋螺栓扭矩過(guò)大導(dǎo)致壓蓋變形,檢查壓蓋墊片的比壓是否合適，檢查密封面間有無(wú)其他固體顆粒，如需要時(shí)對(duì)密封面重新拋光。檢查密封面處的裂紋，更換主、配合密封環(huán)。 </p> <p>

**通常的做法是將密封安裝在填料盒的內(nèi)部。但這種做法要求在密封維修時(shí)將液泵的濕端拆卸下來(lái)，其主要好處是密封的環(huán)境衛(wèi)生易于控制。 </p> <p> <span style="font-size:12px;"> 外密封的安裝方式是將靜態(tài)密封面的方向顛倒過(guò)來(lái)，主軸上的旋轉(zhuǎn)單元位于填料盒壓蓋的外面。外密封主要具有以下五大好處：</span> </p> <p> 安裝容易; </p> <p> 費(fèi)用相對(duì)較低; </p> <p> 可以連續(xù)監(jiān)控和清潔; </p> <p> 適于無(wú)法在內(nèi)部安裝密封的很小填料盒; </p> <p> 由于其位置接近軸承，對(duì)主軸偏差的困難影響較少。 </p> <p> <span style="font-size:12px;"> 其主要缺點(diǎn)是離心力會(huì)將固體顆粒從密封的下面甩向密封的接觸面上。因此，這類(lèi)密封主要適用于清潔且不含有磨料的液體。</span> </p> <p> <span style="font-size:12px;"> 近年來(lái)，分離式密封已成為外密封中的另一重要附加特性。分離式密封是一個(gè)成套總成，安裝于填料盒與軸承套之間，采用這種設(shè)計(jì)，在密封需要更換時(shí)，不需要每次都拆卸液泵。這類(lèi)密封結(jié)合探討其他設(shè)計(jì)標(biāo)準(zhǔn)正在逐步開(kāi)發(fā)之中。由于這種設(shè)計(jì)易于更換密封，因此應(yīng)抵擋**只更換密封件的這種誘惑，而對(duì)出現(xiàn)故障的根源不做進(jìn)一步的調(diào)查，這一點(diǎn)非常重要。</span> </p> <p> <br /> </p><p> 油封主要由密封體、加強(qiáng)骨架和自緊螺旋彈簧等幾部分組成。密封體按照不同部位又分為底部、腰部、刃口和密封唇等。。 </p> <p> <span style="font-size:12px;">金屬骨架就如同混凝土構(gòu)件里面的鋼筋，起到加強(qiáng)的作用，并使油封能保持形狀及張力。通常，在自由狀態(tài)下的骨架油封，其內(nèi)徑比軸徑小，即具有一定的“過(guò)盈量”。因此，當(dāng)油封裝入油封座和軸上之后，油封刃口的壓力和自緊螺旋彈簧的收縮力對(duì)軸產(chǎn)生一定的徑向緊力，經(jīng)過(guò)一段時(shí)間運(yùn)行后，該壓力會(huì)迅速減小乃至消失，因而，加上彈簧可以隨時(shí)補(bǔ)償油封自緊力。</span> </p> <p> <span style="font-size:12px;">油封外緣使油封在腔體孔內(nèi)固定的同時(shí)，起防止流體從油封外周面與腔體內(nèi)表面的接觸面之間泄漏及侵入的作用。另外金屬骨架是當(dāng)油封固定在腔體內(nèi)時(shí)，起保持配合力的作用。</span> </p> <p> <span style="font-size:12px;">密封唇部是柔性彈性體，設(shè)計(jì)成對(duì)機(jī)械的震動(dòng)及密封流體的壓力變動(dòng)的影響下仍可保持穩(wěn)定的密封作用，并起到保持唇部與軸表面穩(wěn)定接觸狀態(tài)的作用。彈簧可提高密封唇向軸的壓緊力，起維持此壓緊力的作用。唇端部被制作成斜鍥形狀，在端部處按壓軸表面，起密封流體的作用。</span> </p> <p> <span style="font-size:12px;">防塵唇是沒(méi)有與彈簧連接的副唇，起防止塵埃侵入的作用。</span> </p> <p> <br /> 機(jī)械密封的正常運(yùn)行必須具備以下條件：機(jī)械密封的泵軸撓度要小，加上機(jī)械密封自身性能，才能達(dá)到密封效果。</p><div

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。在實(shí)際安裝過(guò)程中，應(yīng)該做好對(duì)裝配圖的核對(duì)工作，并檢各種零件表面是否出現(xiàn)了劃痕、缺點(diǎn)等情況。常州葉輪泵密封市場(chǎng)批發(fā)價(jià)格</p><p

</p> <p>
