液態(tài)烴介質(zhì)是一種低溫液化氣體,具有低沸點(diǎn)、低黏度、高蒸氣壓等特性。在這種工況下使用的機(jī)械密封，密封件材料會(huì)出現(xiàn)冷脆性，大氣中的水氣會(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氣化等。尤其是當(dāng)介質(zhì)稍有泄漏，漏出的液態(tài)烴在大氣側(cè)立即氣化，帶走大量的熱，機(jī)械密封環(huán)境溫度急劇下降，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。 </p> <p> <br /> </p> <p> 根據(jù)實(shí)際經(jīng)驗(yàn),使用金屬波紋管機(jī)械密封比較好,主要表現(xiàn)在用金屬波紋管和柔性石墨代替輔助密封圈,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,如用DBM型、YH604/606/609型等。在液態(tài)烴泵上使用波紋管機(jī)械密封時(shí)應(yīng)注意: </p> <p> 金屬波紋管材料選用耐低溫、韌性好的Hastelloy-C(耐熱鎳基金),AM350,Carpenter20 等; </p> <p> 合理的結(jié)構(gòu)設(shè)計(jì)能保證機(jī)械密封在高速運(yùn)轉(zhuǎn)的情況下不破壞密封端面和波紋管組件; </p> <p> 合理的端面接觸比壓能保證機(jī)械密封的密封性能和避免過(guò)早的失效; </p> <p> 合理的摩擦副材料能保證機(jī)械密封在低溫條件下正常的摩擦性能和密封性能, 避免因磨損過(guò)快而過(guò)早的失效; 機(jī)械密封是依靠彈性元件對(duì)動(dòng)、靜環(huán)斷面的預(yù)緊力來(lái)對(duì)軸向端面進(jìn)行密封的，又稱為端面密封。</p><div style="width:100%;text-align:

機(jī)械密封的平衡對(duì)接觸面的密封壓力有很大影響。這一密封壓力取決于密封本身的有效截面以及填料盒內(nèi)的壓力。 </p> <p> 非平衡型密封的旋轉(zhuǎn)面相反一側(cè)的截面完全暴露于填料盒的壓力范圍之下，這種情況會(huì)使密封面之間產(chǎn)生很高的密封壓力，從而會(huì)使工作溫度提高，加快磨損速度。在高溫工作條件下或液體具有較大腐蝕性和磨擦性的情況下，會(huì)較大程度降低機(jī)械密封的使用壽命。 </p> <p> 對(duì)機(jī)械密封加以平衡，可降低密封壓力，延長(zhǎng)密封的使用壽命。一般采用帶有臺(tái)階的主軸和軸套，降低旋轉(zhuǎn)面的有效截面，就可達(dá)到上述目的。不過(guò)千萬(wàn)別將凈密封壓力調(diào)節(jié)到接近零的水平，因?yàn)檫@樣做的結(jié)果可能會(huì)造成密封面之間的工作狀況不穩(wěn)定，并可能會(huì)因突然的變故而將密封吹開。 </p> <p> 解決這些密封問(wèn)題的答案也許是采用非平衡式密封，對(duì)于某些服務(wù)來(lái)說(shuō)，也許采用非平衡式密封能達(dá)到更好的效果。例如，在某些應(yīng)用領(lǐng)域，與密封的使用壽命相比，也許更強(qiáng)調(diào)對(duì)液體泄漏造成的安全性問(wèn)題。在這種情況下，對(duì)密封的選用也許可理解為更希望選擇具有較高的密封壓力。同樣，在選用較冷液體的密封時(shí)，操作溫度的增加也許是微不足道的。 </p> <p> 不管出于何種考慮，當(dāng)填料盒的壓力超過(guò)50psi時(shí)，一般推薦使用平衡式密封。在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)進(jìn)入密封面、抽空等情況下，都會(huì)導(dǎo)致環(huán)面出現(xiàn)徑向裂紋。南京污水密封生產(chǎn)廠家</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。
