隨著時(shí)代的高速發(fā)展，對(duì)石油資源的需求量不斷增加，石油煉廠的生產(chǎn)任務(wù)越來(lái)越重。泵用機(jī)械在石油煉廠生產(chǎn)過(guò)程中發(fā)揮著非常重要的作用，但在其實(shí)際運(yùn)行過(guò)程中，其機(jī)械密封往往會(huì)出現(xiàn)各種問(wèn)題，不僅影響機(jī)械的正常使用，還容易導(dǎo)致安全問(wèn)題的發(fā)生。文章對(duì)石油煉廠常用機(jī)械密封的設(shè)計(jì)改進(jìn)與應(yīng)用進(jìn)行分析，希望對(duì)中國(guó)石油煉化事業(yè)的發(fā)展起到積極的促進(jìn)作用。 </p> <p> 機(jī)械密封在流體機(jī)械中發(fā)揮著非常重要的作用，可以有效防止機(jī)械內(nèi)部的介質(zhì)流出泵外。其運(yùn)行情況，對(duì)泵用機(jī)械運(yùn)行的穩(wěn)定性有著非常直接的影響，在石油煉化生產(chǎn)過(guò)程中，發(fā)揮著非常重要的作用。各種流體機(jī)械在化工生產(chǎn)中，有著非常明顯的應(yīng)用，隨著石油煉化技術(shù)的高速發(fā)展，流體機(jī)械的應(yīng)用參數(shù)水平也在不斷提高，對(duì)機(jī)械性能要求也在不斷提高，轉(zhuǎn)軸密封的作用非常突出。我國(guó)對(duì)機(jī)械密封的研究開(kāi)始較晚，從上個(gè)世紀(jì)80 年代，機(jī)械密封在石油煉化產(chǎn)業(yè)中才開(kāi)始得到大規(guī)模的應(yīng)用。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="常州管道泵密封生產(chǎn)企業(yè)"

在機(jī)械行業(yè)中填料密封主要用作動(dòng)密封,常用作離心泵、壓縮機(jī)、真空泵、攪拌機(jī)的轉(zhuǎn)軸密封。填料裝入填料腔以后,經(jīng)壓蓋螺絲對(duì)它作軸向壓縮,當(dāng)軸與填料有相對(duì)運(yùn)動(dòng)時(shí),由于填料的塑性,使它產(chǎn)生徑向力,并與軸緊密接觸。與此同時(shí),填料中浸漬的潤(rùn)滑劑被擠出,在接觸面之間形成油膜。由于接觸狀態(tài)并不是特別均勻的,接觸部位便出現(xiàn) </p> <p> 邊界潤(rùn)滑狀態(tài),稱(chēng)為”軸承效應(yīng)”;而未接觸的凹部形成小油槽,有較厚的油膜,接觸部位與非接觸部位組成一道不規(guī)則的迷宮,起阻止液流泄漏的作用,此稱(chēng)”迷宮效應(yīng)”。這就是填料密封的機(jī)理。良好的密封在于維持“軸承效應(yīng)”和”迷宮效應(yīng)”。也就是說(shuō),要保持良好的潤(rùn)滑和適當(dāng)?shù)膲壕o，若潤(rùn)滑不良,或壓得過(guò)緊都會(huì)使油膜中斷,造成填料與軸之間出現(xiàn)干摩擦,而后導(dǎo)致燒軸和出現(xiàn)嚴(yán)重磨損。因此,我們需要經(jīng)常對(duì)填料的壓緊程度進(jìn)行調(diào)節(jié),使填料中的潤(rùn)滑劑在運(yùn)行一段時(shí)間而有所流失之后,再擠出一些潤(rùn)滑劑,同時(shí)補(bǔ)償填料因體積變化所造成的壓緊力松弛。當(dāng)然這樣經(jīng)常擠壓填料,而后將使浸漬劑枯竭,所以定期更換填料是必要的。此外,為了維持液膜和帶走摩擦熱,有意讓填料處有少量泄漏也是必要的。
