class="box"><p><p> 帶你了解油液監(jiān)測技術的內涵 </p> <p> 早期的油液監(jiān)測源于油污染分析，主要是通過油品理化指標的常規(guī)檢測，反映油品的質量和評價油品的潤滑性能。當時這類分析常作為石油公司產品銷售后的技術服務項目而進行。通過80年代學術界和工業(yè)界的積極探索，上海軌道交通設備油液監(jiān)測意義，上海軌道交通設備油液監(jiān)測意義，油液監(jiān)測技術已成為設備診斷技術體系中與振動監(jiān)測、溫度監(jiān)測、性能參數監(jiān)測共同發(fā)展的主要方法之一，上海軌道交通設備油液監(jiān)測意義。進入90年代以后，油液監(jiān)測技術正日益朝著多種方法集成、在線與離線并舉、監(jiān)測診斷維修管理融為一體和方法與儀器的智能化方向發(fā)展，取得了不少令人振奮的進步。油液監(jiān)測技術是一種有效的機械狀態(tài)檢測和故障診斷的方法。對油液監(jiān)測不能*認為是潤滑油分析和磨粒分析技術兩大部分。 </p> <p> <br /> </p> <p> <br /> 油液監(jiān)測與設備診斷技術之間的關聯。上海軌道交通設備油液監(jiān)測意義</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

在工業(yè)生產中齒輪油的作用是非常大的，它的主要作用是用來減輕齒輪在運轉時的阻礙。可是齒輪油在使用的時候也有一個問題困擾著大家，那就是泡沫問題了。那么你知道齒輪油產生泡沫的危害嗎？下面由油液監(jiān)測機構**來介紹下吧：1.運行中產生異常噪音，潤滑不足，齒輪油流動不暢、輪齒之間不能形成完整光滑的潤滑油膜，齒輪嚙合部位摩擦過大而導致局部過熱，進而會引起擦傷、點蝕等嚴重磨損。從而影響齒輪運轉的穩(wěn)定；2.造成齒輪潤滑不足；3.引起油溫升高；加速齒輪油變質速度、縮短齒輪油的有效壽命；4.造成齒輪油溢出損失、并且引起安全隱患；5.造成氣蝕，腐蝕、損壞金屬表面。 </p> <p> <br /> 上海船舶主機油液監(jiān)測應用怎么理解油液監(jiān)測的摩擦學基礎?</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海軌道交通設備油液監(jiān)測意義,油液監(jiān)測" src="https://tyunfile.71360.com/UploadFile/shrunkai/637368830167626953/1072543.jpg"></div><p> 變壓器油油液監(jiān)測的目的是什么？ </p> <p> 變壓器油在電氣設備(變壓器、電抗器、互感器、充油套管、油開關等)中主要起絕緣、散熱冷卻、滅弧、保護和信息載體等作用，而不是傳統潤滑油的潤滑與抗磨，嚴格意義上講并非潤滑油。通常變壓器油要在電氣設備中運行很長時間，在選油及維護得當的情況下，變壓器油可以運行30年甚至與電氣設備同壽命。運行中變壓器油的質量變化除與變壓器油本身質量有關外，與電氣設備的運行狀況有著直接的關系。電行業(yè)對運行變壓器油的油液監(jiān)測主要有兩個目的：一是掌握油品的變化趨勢，為變壓器油的再生處理和換油提供依據；更重要的是通過變壓器油這種信息載體，了解電氣設備的運行狀況，及早發(fā)現并排除電氣設備的非正常運行和故障，保證電氣設備的長周期安全運行。 </p> <p> <br /> </p> <p> <br /> </p><p> 解讀油液監(jiān)測技術在盾構機上的應用 </p> <p> 油液監(jiān)測包括理化分析、污染分析、磨損分析。磨損分析有鐵譜分析和光譜分析。理化分析可以判斷油品變質情況，評估油品使用壽命和設備潤滑狀態(tài)。鐵譜分析側重于對出現故障設備進行故障識別；光譜分析可以對設備的磨損趨勢進行狀態(tài)監(jiān)測；兩者結合可以綜合評估設備潤滑磨損狀態(tài)。污染分析能定量檢測油液中污染顆粒數量和等級。對于盾構機設備來說，油液分析的主要項目包括：運動黏度、鐵譜、水分、污染度和光譜分析等，檢測對象主要為盾構機的液壓油、主驅動減速機齒輪油、主軸承齒輪油、螺旋輸送機減速箱齒輪油、拼裝機減速機齒輪油、皮帶機減速機齒輪油等。根據在用油使用指標及盾構機的運行工況制定盾構機在用油樣的檢測項目。關于油液監(jiān)測界限值的制定。</p><div

src="https://tyunfile.71360.com/UploadFile/shrunkai/637368830616552735/6123735.jpg"></div><p> 齒輪油油液監(jiān)測的要點有哪些？ </p> <p> 建立在熟悉和掌握了齒輪摩擦副的潤滑狀態(tài)和失效模式的基礎上，便可以對齒輪油實施有效和針對性的油液監(jiān)測。在用齒輪油重要的性能有粘度、酸值、水分、抗氧劑、戊烷不溶物、防銹性、抗泡性。除監(jiān)測這些性能外，進行磨損分析也是很必要的。 </p> <p> 1.磨損分析：磨損分析主要是通過對磨損產物(顆粒)的監(jiān)測推斷齒輪運轉是否正常，包括磨損物的總量、化學組分、尺寸分布和表面形態(tài)等幾個方面。 </p> <p> 2.酸值：新齒輪油的重要性能之一是它的氧化安定性。 </p> <p> 3.水：水可能因冷卻器泄漏、正常排氣以及系統密封不嚴等原因而進入齒輪系統。 </p> <p> 4.抗氧劑：抗氧劑的監(jiān)測對于監(jiān)控工業(yè)齒輪油及其剩余有效壽命是很重要的。 </p> <p> 5.戊烷不溶物：戊烷不溶物可能包括非油溶性材料和一些源自基礎油或添加劑衰變的樹脂狀物質。 </p> <p> 6.防銹性：由潤滑油提供的防銹保護對齒輪系統是非常重要的。 </p> <p> 7.抗泡性：齒輪系統產生泡沫有三個可能的來源：(1)系統設計對潤滑劑的發(fā)泡傾向產生重大影響；(2)抗泡劑可能被機械性脫除；(3)油品退化、外界污染物引起。 </p> <p> 8.粘度：粘度是齒輪油**重要的性能，因為流體潤滑條件下油膜厚度主要取決于油品的粘度特性。 </p> <p> <br /> </p> <p> <br /> 油液監(jiān)測發(fā)展的過去和現在。上海冷卻液油液監(jiān)測多少錢</p><p style="text-indent:25px">油液監(jiān)測的過去和現在。上海軌道交通設備油液監(jiān)測意義</p><p> 設備磨損的油液監(jiān)測技術能起到什么作用？ </p> <p> 機械設備的磨損總是不可避免的。磨損過程一般分為三個階段，即磨合磨損、穩(wěn)定磨損和劇烈磨損。如果過快或過早出現異常磨損，則應查明原因，及時消除。油液監(jiān)測的目的是控制設備的磨損速率，因此應能涵蓋引發(fā)異常磨損的所有因素，油液監(jiān)測監(jiān)控設備磨損的技術主要包括三方面的內容：1、磨損顆粒分析2、污染監(jiān)測與控制3、潤滑油品質監(jiān)測。磨損顆粒分析目的是了解設備的磨損狀態(tài)及原因，屬于預知性維修范疇，其它兩方面監(jiān)測的目的是為了延長設備的使用壽命，屬于主動性維修范疇。上海軌道交通設備油液監(jiān)測意義</p></p><br
