point）是在規(guī)定的試驗(yàn)條件下，油液表面揮發(fā)的油氣發(fā)生閃燃的比較低溫度。當(dāng)油液表面揮發(fā)的油氣與空氣里的氧氣混合，如果閃點(diǎn)較低，就比較容易發(fā)生閃燃，因此潤滑油的閃點(diǎn)下降主要的問題是可能引起燃燒甚至火災(zāi)問題，如果發(fā)生閃燃還會損壞密封，造成泄漏。潤滑油的閃點(diǎn)應(yīng)越高越好，但是閃點(diǎn)高不能說明潤滑油就有出色的高溫性能。基礎(chǔ)油裂解是潤滑油閃點(diǎn)降低的原因之一，當(dāng)油或者設(shè)備靠近高溫?zé)嵩?，如高溫蒸汽、高溫熔爐等，潤滑油的油溫如果高于550℃，就可能發(fā)生裂解,造成潤滑油的閃點(diǎn)降低。潤滑油里混入其它化學(xué)物質(zhì)也可能造成閃點(diǎn)降低，在設(shè)備維護(hù)中，由于操作不當(dāng)造成油液受到污染、給油液進(jìn)行采樣時(shí)油樣受到了污染等情況，都可能給潤滑油里引入其它化學(xué)物質(zhì)，造成油液的閃點(diǎn)降低。另外，潤滑油里如果混入其它輕質(zhì)組分的油類，也會造成閃點(diǎn)降低，例如混入閃點(diǎn)低的燃料油。閃點(diǎn)降低主要影響安全問題，尤其在接觸明火、熱源等情況下，增加火災(zāi)和閃燃的危險(xiǎn)。通過潤滑油檢測，可以判別潤滑油的閃點(diǎn)是否正常。

潤滑就是用潤滑劑減少(或控制)兩摩擦表面之間的摩擦力或其他形式的表面破壞的作用，從而減少磨擦。因?yàn)閮蓚€(gè)不同的表面接觸，會互相產(chǎn)生摩擦，并產(chǎn)生下列后果：磨損、噪音、高溫。如果我們在兩者之間加上了潤滑劑，便可以減少上述情況的出現(xiàn)。潤滑油也是潤滑劑其中的一種，它可使機(jī)件表面形成一個(gè)油膜，并介于兩個(gè)互相接觸的機(jī)件之間。從而使兩者間的活動變得更容易、平滑、快捷，有效降低摩擦所產(chǎn)生的損毀；因此，如果希望發(fā)動機(jī)達(dá)到良好的潤滑效果，選擇正確的潤滑以及定期的潤滑油檢測必不可少。用手摸、眼看機(jī)油粘度的方法并不能夠鑒別機(jī)油的質(zhì)量，因?yàn)闄C(jī)油能起到潤滑保護(hù)作用，粘度是一個(gè)非常重要的因素，機(jī)油的粘度一般會隨溫度的變化而變化。溫度高時(shí)機(jī)油會變稀，反之，溫度低時(shí)機(jī)油會變濃，有的機(jī)油這種變化非常大，有的則很小，品質(zhì)高的機(jī)油在常溫下看起來很稠，高溫時(shí)卻變得很稀了，根本起不到潤滑保護(hù)作用。 </p> <p> <br /> </p> <p> <br /> </p><p> 潤滑油檢測能否檢測出潤滑油變質(zhì)嗎？ </p> <p> 工業(yè)潤滑油作為工業(yè)設(shè)備的“血液”，潤滑油失效=設(shè)備失效。因此，設(shè)備的維護(hù)要特別重視潤滑油的作用，選擇品質(zhì)優(yōu)良的油品，選擇正規(guī)的供應(yīng)渠道，做好新潤滑油的驗(yàn)收工作，做好密封、污染控制工作，避免混用潤滑油。換油時(shí)要注意把舊油清理干凈，避免原來變質(zhì)的油對新油造成污染。重視油液檢測，通過油液檢測把好新油的質(zhì)量關(guān)，同時(shí)指導(dǎo)在用設(shè)備的維護(hù)和故障診斷。目前市場上的潤滑油，為改善其潤滑性能都添加了適量的各種添加劑。加有清凈分散劑的內(nèi)燃機(jī)械潤滑油在使用不久后變黑屬正常現(xiàn)象，不能認(rèn)為“油已變質(zhì)”而輕易更換，加有添加劑的潤滑油往往會使軸承表面在使用過程中變黑，這也屬正常現(xiàn)象。因此，在確定潤滑油是否已變質(zhì)時(shí)，不能單憑視覺作判斷，要進(jìn)行綜合分析，有條件時(shí)應(yīng)進(jìn)行潤滑油檢測，做到按質(zhì)換油。所以，答案是肯定的，潤滑油檢測對設(shè)備和用油都是必不可少的。

潤滑油超過保質(zhì)期還能用嗎？這個(gè)問題對于很多使用者來說可能都不是很清楚。嚴(yán)格來說，超過保質(zhì)期的潤滑油不建議使用。但是如果油量較多，丟棄又擔(dān)心造成浪費(fèi)，那么可以從以下幾個(gè)方面考察油質(zhì)問題。首先是進(jìn)行初步的檢查。正常情況下，潤滑油應(yīng)該是清亮，半透明或者透明的液體。如果潤滑油發(fā)生氧化，顏色會發(fā)生變化。另外，潤滑油的透明度降低，說明潤滑油的油質(zhì)發(fā)生了變化。潤滑油如果氣味發(fā)酸，發(fā)臭，都說明已經(jīng)變質(zhì)。此外，油的粘度如果都能觀察到明顯變化(變稀、變稠)，性狀不均勻，都不宜使用。一般來說，工業(yè)潤滑油的儲存時(shí)間建議在1年以內(nèi)，潤滑脂半年以內(nèi)。為了保證良好的設(shè)備潤滑，潤滑油在儲存中應(yīng)遵循“先入先出”，避免潤滑油長期保存，以上方法只是定性的評估潤滑油在儲存后的油質(zhì)情況。如果潤滑油的油量較大，不想浪費(fèi)，那么超過保質(zhì)期的潤滑油在使用前建議做一下潤滑油檢測(油品分析)。通過專業(yè)的潤滑油檢測設(shè)備，可以定量、準(zhǔn)確的測定潤滑油的油質(zhì)。上海齒輪機(jī)潤滑油檢測有哪些</p></p><br
