<p> 閃點(diǎn)是表示石油產(chǎn)品著火危險(xiǎn)性的指標(biāo)，對輕質(zhì)潤滑油來說，由于其閃點(diǎn)較低，易著火，可通過閃點(diǎn)的來判斷其著火危險(xiǎn)性。而對于多數(shù)中質(zhì)和重質(zhì)潤滑油來說，閃點(diǎn)高，多達(dá)200℃以上.不易若火，因此測定的目的主要是檢查是否混入輕質(zhì)燃料。因?yàn)榛烊胼p質(zhì)燃料后閃點(diǎn)會大幅度下降，如內(nèi)燃機(jī)油在使用中因未燃燒完的燃油流入曲軸箱，使?jié)櫥褪艿较♂?，閃點(diǎn)便會下降。閃點(diǎn)對油料的運(yùn)翰及儲存也有著重要的意義。油品的危險(xiǎn)等級是根據(jù)閃點(diǎn)來劃分的。閃點(diǎn)在45℃以下的為易燃品，45℃以上為可燃品。一般來說，潤滑油的閃點(diǎn)比液體燃料的閃點(diǎn)高得多，上海冷凍機(jī)油品檢測實(shí)用技術(shù)，對儲存工作不會帶來危險(xiǎn)。但在輸送中需要給潤滑油加熱時(shí)，絕不能把油品加熱到它的閃點(diǎn)溫度，上海冷凍機(jī)油品檢測實(shí)用技術(shù)，加熱的溫度，上海冷凍機(jī)油品檢測實(shí)用技術(shù)，一般應(yīng)低于閃點(diǎn)2O-3O℃，以防止造成事故隱患。 </p> <p> <br /> 閃點(diǎn)為何成為了油品檢測中的必檢指標(biāo)？上海冷凍機(jī)油品檢測實(shí)用技術(shù)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

鐵譜分析技術(shù)是潤滑油品檢測一種有效手段，其主要的發(fā)展方向是用于機(jī)械設(shè)備狀態(tài)監(jiān)測與故障診斷，尤其在齒輪箱、軸承系統(tǒng)、液壓系統(tǒng)等方面，取得了明顯的效益。鐵譜分析技術(shù)的發(fā)展和普及**豐富了原來主要以振動監(jiān)測為主的設(shè)備故障診斷技術(shù)，尤其對于那些低速、重載、做往復(fù)運(yùn)動的機(jī)械，鐵譜分析技術(shù)更加顯現(xiàn)了其獨(dú)特的優(yōu)點(diǎn)。摩擦學(xué)的研究表明，磨粒的類別和數(shù)量多少及增加的速度與摩擦面材料的磨損程度及磨損速度有直接關(guān)系，而磨損的形態(tài)、顏色及尺寸等則與磨損類型、磨損進(jìn)程有密切關(guān)系。因此這種方法判別磨損故障的部位、嚴(yán)重程度、發(fā)展趨勢及產(chǎn)生的原因等方面能發(fā)揮***的作用。近幾年來研究和實(shí)踐的結(jié)果更進(jìn)一步表明，鐵譜分析方法比其他診斷方法，如振動法、性能參數(shù)法等能更加早期地預(yù)報(bào)設(shè)備的異常狀態(tài)，證明此方法的優(yōu)越性。

根據(jù)磨粒形成機(jī)理，可見不同的磨損形式會產(chǎn)生不同種類的磨粒，這些種類的磨粒具有各自的明顯特征。磨粒根據(jù)其成份可分為紅色金屬氧化物、黑色金屬氧化物、有色金屬、黑色金屬、非金屬等。按磨損機(jī)理和形狀分為正?；瑒幽チ！⑶驙钅チ！訝钅チ?、疲勞剝塊、硬表面切削磨粒、磨粒切削磨粒、嚴(yán)重滑動磨粒等。油品檢測技術(shù)用設(shè)備維修中，主要是根據(jù)油品與機(jī)械設(shè)備磨損的關(guān)系來監(jiān)測狀態(tài)和診斷故障的。油樣中的磨損信息主要包括兩方面，一是潤滑油本身信息，二是機(jī)械磨損信息。潤滑油本身性能信息通過其理化指標(biāo)檢測和檢測來獲得，可以用來判斷潤滑油是否具有必要的潤滑性能；而機(jī)械磨損信息則是通過光譜檢測技術(shù)和鐵譜檢測技術(shù)對油樣中所含磨損顆粒的數(shù)量、形狀、尺寸等檢測而獲得，可以用來確定機(jī)械磨損形式、部位、故障發(fā)生的時(shí)機(jī)、維修的時(shí)機(jī)和方法等。 </p> <p> <br /> </p> <p> <br /> </p><p> 油品檢測中銅片腐蝕性檢測有什么重要性？ </p> <p> 油品檢測中銅片腐蝕是其重要的一個(gè)檢測指標(biāo)，主要是測定油品有無腐蝕金屬的活性硫化物和元素硫。含硫化合物在氣缸內(nèi)燃燒后都生產(chǎn)二氧化硫和三氧化硫，這些氧化硫不*會嚴(yán)重腐蝕高溫區(qū)的零部件，而且還會與氣缸壁上的潤滑油起反應(yīng)，加速漆膜和積碳的形成。所以潤滑油銅片腐蝕檢測很重要！那么銅片腐蝕程度什么樣的情況下要換油呢？銅片腐蝕換油指標(biāo)如下： </p> <p> 液壓油銅片腐蝕結(jié)果＞2a，就要換油，工業(yè)齒輪油銅片腐蝕結(jié)果≥3b，就要換油。油品檢測的銅片腐蝕項(xiàng)目方法有：GB/T 5096（國標(biāo)規(guī)定）、ASTM D130、ASTM D4048、GB/T 7326(潤滑脂適用)目前工業(yè)潤滑油較主要的腐蝕性測定法：GB/T 5096石油產(chǎn)品銅片腐蝕試驗(yàn)，以此檢測方法為例： </p> <p> 把一塊已磨光好的銅片浸沒在一定量的試樣中，并按產(chǎn)品標(biāo)準(zhǔn)要求加熱到指定的溫度，保持一定的時(shí)間。待試驗(yàn)周期結(jié)束時(shí)，取出銅片，在洗滌后與標(biāo)準(zhǔn)色板進(jìn)行比較，根據(jù)浸過油試片所呈現(xiàn)的綠色、黑色、棕黑色或鋼灰色斑點(diǎn)確定腐蝕級別。工業(yè)潤滑油常用的試驗(yàn)條件為100℃（或120℃），3h。

據(jù)油品檢測機(jī)構(gòu)**介紹，油氣泄漏的防治技術(shù)是油氣回收和地下儲油罐、管線密閉技術(shù)。油品泄漏的防治技術(shù)主要是卸油防溢及采用防滲漏系統(tǒng)。它們的主要特點(diǎn)是：1、采用具有精確控制氣液回收比的二次油氣收集裝置。2、加油站的全部地下油罐、油管路、井口、底盆等和部分油氣管采用由復(fù)合材料制造的雙層結(jié)構(gòu)防滲漏系統(tǒng)。3、加油站的各項(xiàng)附屬設(shè)備開始向智能化、系統(tǒng)化發(fā)展。4、加油站信息化的主要設(shè)備之一是液位儀，液位儀已經(jīng)不是單純的進(jìn)銷存管理工具，而是地下儲油罐測漏、管線系統(tǒng)、油氣回收系統(tǒng)等設(shè)備的管理中心。5、EVR法令要求安裝站內(nèi)診斷系統(tǒng)(ISD)，在線實(shí)時(shí)監(jiān)測一級和二級油氣回收系統(tǒng)的工作情況。

潤滑油作為工業(yè)用油的常見品種之一，其質(zhì)量檢測肯定是大家重點(diǎn)關(guān)注的話題，但是潤滑油的種類之多是，各種用油的性能指標(biāo)之雜，也給潤滑油檢測的工作帶來了很多困解的地方。相關(guān)的檢測標(biāo)準(zhǔn)更是數(shù)不勝數(shù)，規(guī)定的各種油品檢測指標(biāo)也不盡相同，以液壓油為例。按GB11118.1-2011《液壓油》規(guī)定的，為了滿足各類系統(tǒng)的要求，液壓油必須具備一定的性能。具體檢測項(xiàng)目有酸值、黏度、相對密度、黏度指數(shù)、抗磨性、防銹性、剪切安定性、低溫性、閃點(diǎn)、氧化安定性、起泡性、破乳化性、水解安定性、空氣釋放性、過濾性等指標(biāo)。這里需要指出的黏度檢測，屬于潤滑油質(zhì)量檢測的重點(diǎn)指標(biāo)。在動力潤滑的條件下，油膜厚度隨油品的黏度提高而增加，但摩擦力亦隨油品黏度的提高而增加。黏度過低的潤滑油不易形成足夠強(qiáng)的油膜，會加速磨損，縮短機(jī)件的使用壽命。反之，潤滑油黏度過高，會加大內(nèi)摩擦力，使壓縮機(jī)的比功率增大，以致增大功耗和油耗，也會在活塞環(huán)槽內(nèi)、氣閥上、排氣通道內(nèi)等處形成沉積物。因此，檢測黏度是潤滑油檢測的首要指標(biāo)。上海冷凍機(jī)油品檢測實(shí)用技術(shù)</p></p><br
