在選用潤滑脂時(shí)，首先應(yīng)明確潤滑脂所起的作用，即在潤滑減摩、防護(hù)、密封等方面所要起的作用。作為減摩用的潤滑脂，主要考慮耐高低溫的范圍，負(fù)荷與轉(zhuǎn)速等。作為防護(hù)用的潤滑脂，主要考慮所接觸的介質(zhì)與材質(zhì)，著重考慮對金屬、非金屬的防護(hù)性質(zhì)與安定性。作為密封用的潤滑脂則應(yīng)考慮接觸的密封件材質(zhì)與介質(zhì)，根據(jù)潤滑脂與材質(zhì)(特別是橡膠)的相容性來選擇適宜的潤滑脂。正確選用潤滑脂，以下幾點(diǎn)可做參考：(1)工作溫度(2)速度(3)負(fù)荷(4)環(huán)境條件(5)其他：除了以上幾點(diǎn)外，在選用潤滑脂時(shí)，還要考慮使用時(shí)的經(jīng)濟(jì)性，綜合分析使用此潤滑脂以后是否延長了潤滑周期、加注次數(shù)、脂消耗量、軸承的失效率和維修費(fèi)用等。上海CCS資質(zhì)潤滑油檢測目的通過潤滑油檢測是否能判斷出潤滑油有沒有失效？</p><div

潤滑油中含有水分會降低潤滑油的潤滑性能，據(jù)潤滑油檢測機(jī)構(gòu)**分析，主要表現(xiàn)在以下幾個(gè)方面：（1）降低潤滑油品質(zhì)。潤滑油的組分主要有基礎(chǔ)油和各種添加劑。潤滑油中的水分會促進(jìn)基礎(chǔ)油氧化變質(zhì)，產(chǎn)生乳化現(xiàn)象。（2）降低潤滑能力。水分會降低潤滑油膜的厚度和剛度，進(jìn)而降低油膜的承載能力。水分受到高溫、高壓作用時(shí)，易氣化形成小氣泡，氣泡在高壓下破裂，會對摩擦副表面造成氣蝕磨損；在低溫時(shí)，水分流動性變差，會導(dǎo)致供油不足。（3）造成設(shè)備磨損腐蝕和銹蝕。潤滑油中的水與空氣共同作用于鋼鐵零部件，很容易發(fā)生電化學(xué)腐蝕反應(yīng)，使零部件銹蝕。潤滑油添加劑中的某些元素與油中的水結(jié)合，產(chǎn)生酸蝕作用，會使油系統(tǒng)的部件腐蝕和銹斑。（4）促進(jìn)生成油泥。水分還能與潤滑油中的雜質(zhì)如鐵屑發(fā)生反應(yīng)生成鐵皂，鐵皂與油中較大的顆粒聚集在一起形成油泥。這些油泥會堵塞油路，造成摩擦表面供油不足，加快了機(jī)件的磨損，降低了機(jī)械的使用壽命。日常維護(hù)時(shí)一定要注意做好防水密封，可以在油箱呼吸口加裝硅膠干燥劑，經(jīng)常檢查油箱底部是否有游離水。一旦油品水分超標(biāo)，應(yīng)及時(shí)進(jìn)行脫水處理。 </p> <p> <br /> </p><p> 潤滑油檢測中含硫量和活性硫檢測的意義是什么？ </p> <p> 潤滑油里的硫元素以多種形式存在。潤滑油的主要成分是基礎(chǔ)油，大部分基礎(chǔ)油是石油精制而成，而石油中就有硫，基礎(chǔ)油在精制過程中會脫去大部分雜質(zhì)，但是總有一些殘留。在石油中，硫的存在形態(tài)有元素硫、硫化氫以及硫醇、硫醚、二硫化物、噻吩等有機(jī)硫化物，按性質(zhì)可劃分為活性硫化物和非活性硫化物。另外，潤滑油生產(chǎn)過程中要加入添加劑，例如含硫抗磨劑或者含硫極壓劑。這些硫元素在檢測中都算入總含硫量。對于潤滑油檢測來說，檢測含硫量的意義在于，可以幫助我們了解油的極壓性和抗磨性，因?yàn)樵S多潤滑油、金屬加工液里都使用了含硫極壓劑。潤滑油檢測到底能給潤滑油廠家?guī)砟男?shí)質(zhì)性的幫助？</p><div

探討機(jī)器設(shè)備發(fā)生故障的原因，主要包括機(jī)械零件的失效和整機(jī)調(diào)整、裝配不當(dāng)兩大原因。機(jī)械零件的失效有磨損、腐蝕和變形、斷裂等模式，其中磨損失效是**常見的一種。機(jī)械零件的磨損往往會造成機(jī)器設(shè)備精度降低、效率下降與壽命縮短，相應(yīng)地造成生產(chǎn)率降低、材料消耗、維修費(fèi)用上升，對于高生產(chǎn)率、高速度、高精度的自動化設(shè)備而言，其均衡生產(chǎn)受到的影響更大。一切相互接觸并做相對運(yùn)動的設(shè)備零件表面(統(tǒng)稱摩擦副)會產(chǎn)生摩擦，磨損是伴隨摩擦產(chǎn)生的必然結(jié)果，對摩擦副實(shí)施潤滑，則是減少摩擦、降低磨損的重要措施。摩擦學(xué)作為一門實(shí)用性很強(qiáng)、適應(yīng)性很廣的學(xué)科，為改善摩擦、控制磨損和合理潤滑等工程實(shí)際問題的解決奠定了理論基礎(chǔ)，指出了明確的方向，也從側(cè)面印證了潤滑油檢測的重要性。

潤滑油檢測是用來檢驗(yàn)潤滑油的成分以及質(zhì)量是否符合相應(yīng)的出貨標(biāo)準(zhǔn)，這種檢測的目的是為了防止劣質(zhì)油品對汽車或者其它類動力設(shè)備造成損壞。特別是有效的潤滑油檢測項(xiàng)目可以幫助人們徹底杜絕劣質(zhì)油品的流入，油液檢測項(xiàng)目已隨著其應(yīng)用領(lǐng)域的增加而不斷增加，很多人也都是因?yàn)橄嘈偶夹g(shù)先進(jìn)的檢測公司的檢測報(bào)告而選擇相對應(yīng)品牌的潤滑油進(jìn)行訂購。這些公司所出具的檢測報(bào)告除了較為重要的粘度指數(shù)、閃點(diǎn)以及傾點(diǎn)等檢測項(xiàng)目外，還包括腐蝕試驗(yàn)、運(yùn)動粘度、苯胺點(diǎn)等其它檢測項(xiàng)目，不同的檢測項(xiàng)目對于衡量潤滑油的質(zhì)量都具有重要的意義。
