在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤根密封形成了鮮明的對(duì)比：（1）機(jī)械密封與盤根密封在密封性能上，機(jī)械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長(zhǎng)，兩年以內(nèi)無需更換，以往盤根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對(duì)比先后將車間的兩臺(tái)循環(huán)水泵、兩臺(tái)射水泵、凝結(jié)水泵共6臺(tái)泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機(jī)械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場(chǎng)價(jià)格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費(fèi)用在7000元左右，不計(jì)人工費(fèi)用每臺(tái)水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺(tái)泵的機(jī)械密封價(jià)格在600元左右，至少一個(gè)大修期在3年以上，江蘇化工泵密封，由于摩擦阻力的降低使電耗每小時(shí)下降8度，江蘇化工泵密封，全年節(jié)電在58000度，江蘇化工泵密封，降低成本3萬元左右。因此機(jī)械密封于盤根密封相比優(yōu)勢(shì)十分明顯。

<p> 高溫重質(zhì)油泵的介質(zhì)具有以下共同的特點(diǎn): </p> <p> 溫度高:一般在340一400℃; </p> <p> 介質(zhì)粘度大:在溫度下一般運(yùn)動(dòng)粘度為(12一180)X 10一6m/s; </p> <p> 介質(zhì)有顆粒:如催化劑、焦炭、含有砂粒等其他雜質(zhì)。 </p> <p> 對(duì)于高溫重油介質(zhì)泵用機(jī)械密封?，F(xiàn)在各個(gè)企業(yè)都采用焊接金屬波紋管械密封?，F(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結(jié)構(gòu)，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。

安裝時(shí)，若軸徑外表面粗糙度低或有銹斑、銹蝕、起毛刺等缺點(diǎn)，要用細(xì)砂布或油石打磨光滑；在油封唇口或軸徑對(duì)應(yīng)位置涂上清潔機(jī)油或潤(rùn)滑油脂。 </p> <p> 油封外圈涂上密封膠，用硬紙把軸上的鍵槽部位包起來，避免劃傷油封唇口，用**工具將油封向里旋轉(zhuǎn)壓進(jìn)，千萬不能硬砸硬沖，以防油封變形或擠斷彈簧而失效；若出現(xiàn)唇口翻邊、彈簧脫落和油封歪斜時(shí)必須拆下重新裝入。應(yīng)該注意的是：當(dāng)軸徑?jīng)]有磨損和油封彈簧彈力足夠時(shí)，不要擅自收緊內(nèi)彈簧。應(yīng)用在機(jī)械上的油封一般工作條件惡劣、環(huán)境溫差大、塵埃多、機(jī)具振動(dòng)頻繁使機(jī)件受力狀況不斷變化時(shí)，要勤檢查、保養(yǎng)和維護(hù)。 </p> <p> 如軸徑和軸承磨損嚴(yán)重；油封橡膠老化或彈簧失效等，應(yīng)及時(shí)進(jìn)行修理和更換相應(yīng)部件。 </p> <p> 對(duì)不正常發(fā)熱的部件或總成應(yīng)及時(shí)排除故障；避免機(jī)械超速、超負(fù)荷運(yùn)轉(zhuǎn)，以防止油封唇口溫度升高、橡膠老化、唇口早期磨損等。 </p> <p> <br />
