</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(zhuān)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。 </p><p style="text-indent:25px">目前，污水泵產(chǎn)品常用的密封形式有兩種:填料密封和機(jī)械密封。填料密封，如圖1所示，是古老的一種密封結(jié)構(gòu)，發(fā)源于工業(yè)**之前的傳統(tǒng)密封裝置，有著100年的材料工藝、潤(rùn)滑劑系統(tǒng)和制造方法，并保持持續(xù)進(jìn)步，目前很多的應(yīng)用場(chǎng)合。經(jīng)分析，該軟填料密封結(jié)構(gòu)存在如下缺點(diǎn):1.密封介質(zhì)含有的雜質(zhì)嚴(yán)重影響密封性能。雜質(zhì)進(jìn)入軟填料密封內(nèi)部，進(jìn)一步增大了填料密封和軸套之間的摩擦、磨損。雖然材料耐磨性較好，但是使用效果仍然不佳，泄漏頻繁。另外由于沒(méi)有采用封液對(duì)填料密封進(jìn)行潤(rùn)滑冷卻，也加劇了填料與軸套之間的磨損。2.工作狀態(tài)不穩(wěn)定需頻繁調(diào)整和更換填料。由于軟填料自身具有的粘彈特性，在工作狀態(tài)下會(huì)出現(xiàn)明顯的應(yīng)力松弛。為保持其正常的密封功能，需不斷地通過(guò)壓緊壓蓋來(lái)增大填料與軸的徑向接觸力，同時(shí)也增大了軟填料與軸的磨損，因此不得不經(jīng)常更換(或添加)填料，維修工作量和費(fèi)用較大增加。3.磨損嚴(yán)重致使能耗量大。根據(jù)軟填料密封的工作機(jī)理，填料密封與軸(或軸套)之間必須保持較大的徑向接觸壓力以維持密封，因此填料和軸(或軸套)的摩擦、磨損都很?chē)?yán)重，在密封很快失去工作能力的同時(shí)，造成相當(dāng)大的能耗浪費(fèi)。影響密封的主要因素有哪些？密封本身質(zhì)量、工藝操作條件、裝配安裝精度、主機(jī)本身精度、密封輔助系統(tǒng)。</p><div

采用合成橡膠或聚四氟乙烯制成的O形圈，V形圈及其他形狀的密封圈，以防止靜環(huán)與壓蓋之間(或靜環(huán)座之間)的泄漏，并使靜環(huán)具有一定浮動(dòng)性。 </p> <p> 動(dòng)環(huán)密封圈 </p> <p> 采用與靜密封圈相同的密封圈，防止介質(zhì)從動(dòng)環(huán)與軸之間的間隙中產(chǎn)生泄漏，并使動(dòng)環(huán)具有一定的浮動(dòng)性，保證動(dòng)環(huán)與靜環(huán)的良好貼合，當(dāng)密封面磨損后能使動(dòng)環(huán)可以產(chǎn)生軸向移動(dòng)。 </p> <p> 彈性元件 </p> <p> 彈性元件主要起補(bǔ)償及緩沖的作用。彈性力使機(jī)械密封端面產(chǎn)生合理的端面比壓，也是機(jī)械密封使用壽命和密封性能的關(guān)鍵影響因素。彈性元件主要包括彈簧和波紋管兩種，通常采用圓柱螺旋彈簧，但也有采用圓錐彈簧和波形彈簧的；波紋管類(lèi)彈性元件包括橡膠波紋管、聚四氟乙烯波紋管和金屬波紋管。 </p> 機(jī)械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機(jī)械密封，耐高壓、耐腐蝕機(jī)械密封等。鹽城泵用密封批量采購(gòu)</p><p style="text-indent:25px">密封件的存放室溫比較好在30℃以下，避免密封件產(chǎn)生高溫老化。鹽城泵用密封批量采購(gòu)</p><p
