</p> <p> 泵用機(jī)械密封種類(lèi)繁多，型號(hào)各異，但泄漏點(diǎn)主要有五處： </p> <p> 軸套與軸間的密封動(dòng)環(huán)與軸套間的密封動(dòng)、靜環(huán)間密封對(duì)靜環(huán)與靜環(huán)座間的密封密封端蓋與泵體間的密封 </p> <p> 現(xiàn)象：操作中密封發(fā)出爆裂聲（端面爆裂聲） </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>

油封是用于密封機(jī)械設(shè)備中旋轉(zhuǎn)軸的封油用密封元件，而腔體基本上是靜止的，所以油封又稱旋轉(zhuǎn)軸唇形密封圈。 </p> <p> <span style="font-size:12px;">機(jī)械的摩擦部分由于在機(jī)械運(yùn)轉(zhuǎn)時(shí)有油進(jìn)入，為防止這些油從機(jī)械的間隙中泄漏而使用油封，并且除了油以外還需要防止水與化學(xué)藥液的泄漏以及塵埃及土砂從外部侵入，這時(shí)候也要用到油封。</span> </p> <p> <span style="font-size:12px;">油封的密封狀態(tài)，一是油封外緣和腔體之間為靜態(tài)密封，同時(shí)保證油封外緣在腔體之間的可靠定位。二是油封密封唇和軸之間的密封狀態(tài)，當(dāng)軸旋轉(zhuǎn)時(shí)為動(dòng)態(tài)密封，當(dāng)軸靜止時(shí)為靜態(tài)密封。各種影響因素的綜合作用及其相互作用，都對(duì)油封的密封性能和使用壽命產(chǎn)生了很大影響。</span> </p> <p> <br /> </p> 南通離心泵密封生產(chǎn)廠家隨著機(jī)械密封在機(jī)泵中的使用越來(lái)越多，使用要求也越來(lái)越高。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州油泵密封哪家比較便宜,封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247293837011719/358206.jpg"></div><p> 雙重密封和液體阻隔裝置 </p> <p> 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> </p><p> 離心泵的機(jī)械密封使用與潤(rùn)滑保養(yǎng) </p> <p> <p> 在液體介質(zhì)中工作的機(jī)械密封，一般均依靠液體介質(zhì)在動(dòng)、靜環(huán)摩擦面間所形成的液膜進(jìn)行潤(rùn)滑。因此，維持摩擦面間的液膜是機(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> <p> 強(qiáng)化潤(rùn)滑的結(jié)構(gòu) </p> <p> 靜壓潤(rùn)滑： </p> <p> 所謂靜壓潤(rùn)滑是將有壓力的潤(rùn)滑液體直接引入摩擦面以起到潤(rùn)滑的作用。用此有壓力的潤(rùn)滑液與機(jī)械內(nèi)的流體壓力相對(duì)抗，此種形式通常也稱為流體靜壓力密封。引入的潤(rùn)滑液體由單獨(dú)的液源供給，如液壓泵等。只要條件允許，應(yīng)盡可能把氣體介質(zhì)條件轉(zhuǎn)換為液體介質(zhì)條件，這樣既便于潤(rùn)滑又便于密封。氣體介質(zhì)的機(jī)械密封應(yīng)采取措施建立氣膜潤(rùn)滑，如采用氣體靜壓受控膜機(jī)械密封或固體潤(rùn)滑，即選用自潤(rùn)滑材料作動(dòng)環(huán)或靜環(huán)。 </p> <p> 端面偏心： </p> <p> 一般機(jī)械密封，動(dòng)環(huán)的中心、靜環(huán)的中心和軸的中心線都在一條直線上，偏心尺寸不能過(guò)大，特別是對(duì)于高壓，偏心會(huì)使端面所受的壓力不均勻，而造成磨損不均勻。對(duì)于高轉(zhuǎn)速密封，不宜用動(dòng)環(huán)作為偏心環(huán)，否則由于離心力的平衡會(huì)使機(jī)器發(fā)生振動(dòng)。如果將動(dòng)環(huán)或靜環(huán)中的某一個(gè)環(huán)的端面中心做成與軸的中心線偏移部分距離，便能使環(huán)在旋轉(zhuǎn)時(shí)不斷帶入潤(rùn)滑液至滑動(dòng)面間起潤(rùn)滑作用。 </p> <p> <br /> </p> 介質(zhì)的低于飽和蒸汽壓力，使得端面液膜發(fā)生閃蒸，喪失潤(rùn)滑。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州油泵密封哪家比較便宜,封"

在凝結(jié)過(guò)程中，由于體積急劇縮小，四周的液體以極大的速度沖向整個(gè)凝結(jié)空間，使泵內(nèi)造成沖擊振動(dòng)和噪音。在壓力很大、頻率很高的液體質(zhì)點(diǎn)連續(xù)沖擊下，金屬表面逐漸因疲勞而破壞，這種破壞稱為剝蝕。 </p> <p> 同時(shí)溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機(jī)械剝蝕的共同作用，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進(jìn)口氣蝕的措施有以下幾點(diǎn)： </p> <p> 提高泵的氣蝕性能水平，滿足現(xiàn)場(chǎng)裝置的氣蝕性能的要求。 </p> <p> 泵應(yīng)當(dāng)在低于允許吸液高度下操作，以保證整個(gè)裝置安全可靠的運(yùn)轉(zhuǎn)。 </p> <p> 采用抗氣蝕材料制造葉輪，如：2Cr13、稀土合金鑄鐵、高鎳鉻合金材料等，比普通鑄鐵的抗氣蝕能力要好得多。 </p> <p> <br /> </p> <p> <br

style="text-indent:25px">液態(tài)烴介質(zhì)是一種低溫液化氣體，具有低沸點(diǎn)、低粘度、高蒸汽壓等特性。在這種工況下應(yīng)用的機(jī)械密封，會(huì)使密封材料出現(xiàn)冷脆性，大氣中的水汽會(huì)在密封裝置的大氣側(cè)面上凍結(jié)，摩擦副端面液膜容易汽化等。尤其是當(dāng)介質(zhì)稍有泄漏，漏出的液態(tài)烴在大氣側(cè)立即汽化，帶走大量熱，機(jī)械密封環(huán)境溫度急劇下降，使用一般的密封材料，如橡膠或聚四氟乙烯普遍變脆，導(dǎo)致密封失效，泄漏增大而不可收拾。有些企業(yè)采用雙端面l機(jī)械密封，在介質(zhì)和大氣端設(shè)一隔離室，其間通以封油以緩和低溫的影響。但這種結(jié)構(gòu)復(fù)雜且需配封液系統(tǒng)。據(jù)經(jīng)驗(yàn)，使用波紋管機(jī)械密封比較好，主要表現(xiàn)在用屬波紋管和柔性石墨代并輔助密封圈，解決了密封圈材料發(fā)生冷脆而失彈及緩沖作用的問(wèn)題，如DBM型、YH604/606/609型等。蘇州油泵密封哪家比較便宜</p><p
