一般情況下，介質(zhì)的溫度超過(guò)120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問(wèn)題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長(zhǎng)時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會(huì)加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。

油封外圈涂上密封膠，用硬紙把軸上的鍵槽部位包起來(lái)，避免劃傷油封唇口，用**工具將油封向里旋轉(zhuǎn)壓進(jìn)，千萬(wàn)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)。

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(chēng)旋轉(zhuǎn)軸唇形密封圈。 </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>
