一、準(zhǔn)備工作1.更換水泵機(jī)械密封前要認(rèn)真檢查集結(jié)密封零件數(shù)量是否足夠，各元件是否有損壞，特別是動(dòng)、靜環(huán)有無碰傷、裂紋和變形等缺陷，臨沂襄樊五二五機(jī)械密封HTM-40S315Z。如果有問題，需進(jìn)行修復(fù)或更換新備件。2.檢查軸套或壓蓋的倒角是否恰當(dāng)，如不符合要求則必須進(jìn)行修整。3.水泵機(jī)械密封各元件及其有關(guān)的裝配接觸面，在安裝前必須用**或無水酒精清洗干凈。安裝過程中應(yīng)保持清潔，特別是動(dòng)、靜環(huán)及輔助密封元件應(yīng)無雜質(zhì)、灰塵。動(dòng)、靜環(huán)表面涂上一層清潔的機(jī)油或透平油。二、安裝工作1.上緊壓蓋應(yīng)在聯(lián)軸器找正后進(jìn)行，臨沂襄樊五二五機(jī)械密封HTM-40S315Z。螺栓應(yīng)均勻上緊，防止壓蓋斷面偏斜，用塞尺或**工具檢查各點(diǎn)，臨沂襄樊五二五機(jī)械密封HTM-40S315Z，其誤差不大于。2.檢查壓蓋與軸或軸套外徑的配合間隙（及同心度），必須保證四周均勻，用塞尺檢查各點(diǎn)允差不大于。3.彈簧壓縮量要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象，要求誤差±，過大會(huì)增加斷面比壓，加速斷面磨損。過小會(huì)造成比壓不足而不能起到密封作用，彈簧裝上后在彈簧座內(nèi)要移動(dòng)靈活。用單彈簧時(shí)要注意彈簧的旋向，彈簧的旋向應(yīng)與軸的轉(zhuǎn)動(dòng)方向相反。4.水泵機(jī)械密封動(dòng)環(huán)安裝后須保持靈活移動(dòng)，將動(dòng)環(huán)壓向彈簧后應(yīng)能自動(dòng)彈回來。5.先將水泵機(jī)械密封靜環(huán)密封圈套在靜環(huán)背部后，再裝入密封端蓋內(nèi)。注意保護(hù)靜環(huán)斷面。襄樊五二五機(jī)械密封HTM-55D351。臨沂襄樊五二五機(jī)械密封HTM-40S315Z</p><div

2）機(jī)械密封處的泵軸撓度要小，只有滿足類似這樣的外因，再加上良好的機(jī)械密封自身性能，才能達(dá)到理想的密封效果。二、影響泵用機(jī)械密封的外部原因（一）泵軸的軸向竄量機(jī)械密封的密封面要有一定的比壓（～），從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。為了保證這個(gè)比壓，要求泵軸不能有太大的竄量（≤），但在實(shí)際生產(chǎn)中，往往泵軸產(chǎn)生很大的竄量。對機(jī)械密封的使用非常不利的，這種情況在我分廠表現(xiàn)在泵啟動(dòng)過程中，由于不平衡軸向力的存在，使整個(gè)軸發(fā)生向吸入口的竄動(dòng)，造成機(jī)械密封失去密封作用，常用的措施有：葉輪上開平衡孔，泵體上裝平衡管等。（二）泵軸的撓度偏大軸彎曲變形時(shí)橫截面形心沿與軸線垂直方向的線位移稱為撓度，機(jī)械密封要求兩個(gè)密封端面之間受力均勻。但由于泵產(chǎn)品設(shè)計(jì)的不合理，在機(jī)械密封安裝處產(chǎn)生的撓度偏大，使密封處受力不均勻，從而失去密封效果。這種現(xiàn)象大多存在臥式多級離心泵中。（三）沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)計(jì)不合理機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護(hù)密封面，起到冷卻、潤滑、沖走雜物等作用。有時(shí)設(shè)計(jì)人員設(shè)計(jì)不合理，達(dá)不到密封效果；有的設(shè)計(jì)了輔助系統(tǒng)，但由于沖洗液中有雜質(zhì)。昌平區(qū)HRM-198S2襄樊五二五機(jī)械密封LCF40/250襄樊五二五機(jī)械密封。</p><div

機(jī)械密封的密封環(huán)之間應(yīng)有一層液體薄膜，具有下列三個(gè)作用：1.支持密封受到的大部分水壓負(fù)荷。2.作為潤滑劑，減少密封環(huán)生成的摩擦熱。3.使粗糙接觸小化，從而降低磨損率。4.作為傳熱介質(zhì)，轉(zhuǎn)移密封環(huán)直接區(qū)域的熱能。首先我們要研究密封失效的原因，根據(jù)我的經(jīng)驗(yàn)，有如下:生產(chǎn)上的缺陷；設(shè)計(jì)上的缺陷；缺少培訓(xùn)/技術(shù)；在我們拆卸機(jī)械密封的之前，我們先要想好以下幾點(diǎn)：1.主要的泄漏在哪里?2.在外部件上是否有碎片？3.是否觀察到軸或旋轉(zhuǎn)的密封部件有偏心現(xiàn)象？4.有否與系統(tǒng)相關(guān)的震動(dòng)/噪音（如氣穴，接合錯(cuò)位）？5.在“泵”或密封是否存在局部的熱生成？6.在不同的情況下泄漏是否是間歇的，如在不同的溫度下？7.屬何種泄漏，噴射，小滴，水流或流往管道？8.軸承是否有軸向間隙？9.如果是雙端面密封，則檢查隔離液供應(yīng)是否完好。10.密封在軸上的相對位置？拆除密封過程中，我們要注意以下幾點(diǎn)：1.墊片和磨合端面的狀態(tài)？2.軸的情況和尺寸？3.機(jī)器的阻塞/密封氣穴？4.裝到軸上松還是緊？5.機(jī)器的腐蝕？6.機(jī)器里是否有密封碎片？7.在密封安裝到軸上的位置是否有基準(zhǔn)標(biāo)記？8.密封部位的軸的相對硬度？拆除密封的時(shí)候，我們就要注意以下幾點(diǎn)：1.在拆除過程中。</p><p> 泵用機(jī)械密封是精密的部件，制造精度及安裝精度要求都很嚴(yán)格，如果裝配不當(dāng)就會(huì)影響密封性能，要正確安裝必須注意以下幾點(diǎn)：一、泵用機(jī)械密封的冷卻和沖洗1、第一種冷卻形式由水泵的出口或高壓端，將輸送的干凈介質(zhì)，直接沖洗密封端面，然后進(jìn)入泵腔內(nèi)，通過介質(zhì)的不斷循環(huán)，將磨擦端面的的磨擦熱帶走達(dá)到冷卻的效果。2、第二種冷卻方式在第一種冷卻形式的基礎(chǔ)上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來的液體。當(dāng)密封介質(zhì)溫度＞150℃時(shí)除了在冷卻水套中通過冷卻水及靜環(huán)背部冷卻外，應(yīng)采取強(qiáng)制冷卻措施。即從泵出口的干凈介質(zhì)應(yīng)預(yù)先經(jīng)熱交換器冷卻至50℃時(shí)。再進(jìn)入密封腔冷卻沖洗，該形式是冷卻效果良好的一種。3、如介質(zhì)中含有顆?；螂s質(zhì)，必須采用過濾措施，把常溫干凈沖洗液輸入密封腔內(nèi)。二、泵用機(jī)械密封的安裝和技術(shù)要求1、對機(jī)、泵以及機(jī)械密封的配合部分技術(shù)要求：a.軸彎曲度大不得超過。b.部件內(nèi)各零件均符合圖紙要求。上緊壓蓋時(shí)應(yīng)在聯(lián)軸器找正后進(jìn)行，壓緊螺絲應(yīng)均上緊，防止法蘭面偏斜。c.彈簧的壓縮量按圖紙規(guī)定進(jìn)行允許誤差±2mm。軸在安裝機(jī)械密封處的振擺量不得大于。軸的軸向竄動(dòng)量不允許大于。襄樊五二五機(jī)械密封LC550/700。</p><div

其余安裝及外型尺寸不受影響。副葉片和固定導(dǎo)葉加工難度較大，一般離心泵上沒有，在改造時(shí)可根據(jù)情況決定是否采用。在低于50m揚(yáng)程的泵也可不采用副葉片和固定導(dǎo)葉，只采用副葉輪。3、動(dòng)力密封裝置整體工作原理在運(yùn)轉(zhuǎn)時(shí)，離心泵工作葉輪與起密封作用的副葉輪同軸旋轉(zhuǎn)，工作葉輪泄漏出來的液體流到副葉輪后，通過副葉輪作用產(chǎn)生的壓力，與泄漏液體的壓力在副葉輪頂端與密封總成內(nèi)端面處達(dá)到平衡，從而使泄漏液體起到密封作用。在停車時(shí)，副葉輪動(dòng)力密封不起作用，泵內(nèi)液體壓力較小，泄漏到副葉輪的液體通過油封進(jìn)行密封。4、副葉輪動(dòng)力密封設(shè)計(jì)應(yīng)注意的問題（1）離心泵采用副葉輪密封無需考慮冷卻措施，若用于氣體密封，則需設(shè)置旁通回路從外部引入封液進(jìn)行冷卻。（2）副葉輪密封消耗的附加功率與其外徑的五次方成正比，因此一般不采用外徑過大的方案，而應(yīng)該同時(shí)設(shè)副葉片和副葉輪，以便減小外徑，減少功耗。（3）副葉輪動(dòng)力密封及停車密封裝置材料的選擇要根據(jù)使用介質(zhì)的要求來決定，否則要影響使用壽命，特別是停車密封還要考慮冷卻和潤滑等。（4）因?yàn)楦比~輪葉片的進(jìn)口角同副葉輪的密封能力無關(guān)，所以葉片形狀可以用徑向直葉片以便加工制造。HTM-40S251襄樊五二五機(jī)械密封。三門峽襄樊五二五機(jī)械密封LCF50/350N2</p><p

沖洗液的流量、壓力不夠，沖洗口位置設(shè)計(jì)不合理等原因，也同樣達(dá)不到效果。常用的措施有：1．在條件允許的情況下，盡量設(shè)計(jì)輔助沖洗系統(tǒng)。沖洗壓力一般要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力等因素來計(jì)算。軸封腔壓力很高或者壓力幾乎接近該密封使用極限時(shí)，也可由密封腔引液體至低壓區(qū)，使軸封液體流動(dòng)以帶走摩擦熱。2．根據(jù)每種泵的操作條件，合理地配置管路和附件。如冷卻器、孔板、過濾器、閥門、流量指示器、壓力表、溫度等。實(shí)際上密封的可靠性和壽命，在很大程度上取決于密封輔助系統(tǒng)的配置，另外泵軸、軸套、泵體、密封腔體的加工精度不夠等原因的存在對機(jī)械密封的密封效果也是很不利的，在這些方面應(yīng)該做到嚴(yán)格把關(guān)。（四）振動(dòng)偏大及消除措施機(jī)械密封振動(dòng)偏大往往不是機(jī)械密封自身的原因，而是泵軸設(shè)計(jì)不合理、加工精度不夠、靠背輪的平行度偏大、徑向力大等原因，消除泵振動(dòng)措施有：泵、電機(jī)、底座、現(xiàn)場管路等輔助設(shè)備在現(xiàn)場安裝時(shí)，要嚴(yán)格把關(guān)，消除振動(dòng)源。（五）泵氣蝕的原因及改進(jìn)措施離心泵葉輪入口處是泵內(nèi)壓力小的地方，當(dāng)此處的壓力等于或低于工作溫度下被輸送液體的飽和蒸汽壓1pt時(shí)，液體就會(huì)沸騰汽化，產(chǎn)生大量氣泡。臨沂襄樊五二五機(jī)械密封HTM-40S315Z</p><p
