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。

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題,如用DBM型、YH604/606/609型等，泰州水泵密封廠家批發(fā)。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>

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, 避免因磨損過快而過早的失效; </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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 />

4月16日微型水泵能在不加引水的情況下，可以吸水，就表示這個(gè)水泵有自吸的功能。可抽取水、液體(溶液)，適用于需要進(jìn)行液體轉(zhuǎn)移、提升、清洗、噴灑、沖洗、灌溉等等多種場合。水泵的抽水管內(nèi)是空氣的情況下，利用泵工作時(shí)形成的負(fù)壓（真空），在大氣壓的作用下將低于抽水口的水壓上來，再從水泵的排水端排出。這個(gè)過程前是不需要加“引水（引導(dǎo)用的水）”的。就是說具備這種自吸能力的微型水泵，就叫“微型自吸水泵”。簡稱：“微型吸泵”原理類似微型真空泵。 </p> <p> 微型水泵油脂粘度是發(fā)揮真空泵性能的重要因素之一，液體的粘度是液體流動(dòng)阻力，或者說是液體的內(nèi)摩擦力，因此粘度越大，各種運(yùn)動(dòng)部件所受的阻力就越大；但粘度太小，泵的密封性能變差，引起氣體泄漏，真空變劣。因此，各類微型水泵對(duì)潤滑油的選擇極為重要。 </p><div style="width:100%;text-align:
