所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動(dòng)環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動(dòng)環(huán)和動(dòng)環(huán)座的連接松動(dòng)。3、選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動(dòng)環(huán)輔助密封圈，不需要克服動(dòng)環(huán)補(bǔ)償時(shí)與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯(cuò)的效果。二、低溫下的機(jī)械密封在煉油化工裝置中，低溫輸送的介質(zhì)一般都具有豁度小、潤滑性差、容易氣化的特點(diǎn)，而且介質(zhì)在氣化時(shí)大量吸熱，使周圍溫度急劇下降，造成空氣中水氣的凝結(jié)，導(dǎo)致端面及其周圍結(jié)冰，使端面貼合不嚴(yán)引起泄漏。同時(shí)，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時(shí)轉(zhuǎn)移，必然會(huì)加劇端面處的氣化，造成惡性循環(huán)，加速密封面的早期失效。另外，低溫密封的輔助密封圈在低溫下發(fā)硬失彈也容易導(dǎo)致泄漏。對(duì)低溫密封，揚(yáng)州HB50-50-50柳州酸王泵用機(jī)械密封，除了選擇合適的輔助密封圈材質(zhì)外，還要注意以下幾點(diǎn)：1，揚(yáng)州HB50-50-50柳州酸王泵用機(jī)械密封，揚(yáng)州HB50-50-50柳州酸王泵用機(jī)械密封、改進(jìn)密封結(jié)構(gòu)及正確選擇摩擦副材料。實(shí)踐證明。HB150-125-16柳州酸王泵用機(jī)械密封。揚(yáng)州HB50-50-50柳州酸王泵用機(jī)械密封</p><div

泵用機(jī)械密封種類繁多，型號(hào)各異，但泄漏點(diǎn)主要有五處：1)、軸套與軸間的密封；2)、動(dòng)環(huán)與軸套間的密封；3)、動(dòng)、靜環(huán)間密封；4)、對(duì)靜環(huán)與靜環(huán)座間的密封；5)、密封端蓋與泵體間的密封；1、安裝靜試時(shí)泄漏機(jī)械密封安裝調(diào)試好后，一般要進(jìn)行靜試，觀察泄漏量。如泄漏量較小，多為動(dòng)環(huán)或靜環(huán)密封圈存在問題；泄漏量較大時(shí)，則表明動(dòng)、靜環(huán)摩擦副間存在問題。在初步觀察泄漏量、判斷泄漏部位的基礎(chǔ)上，再手動(dòng)盤車觀察，若泄漏量無明顯變化則靜、動(dòng)環(huán)密封圈有問題；如盤車時(shí)泄漏量有明顯變化則可斷定是動(dòng)、靜環(huán)摩擦副存在問題；如泄漏介質(zhì)沿軸向噴射，則動(dòng)環(huán)密封圈存在問題居多，泄漏介質(zhì)向四周噴射或從水冷卻孔中漏出，則多為靜環(huán)密封圈失效。此外，泄漏通道也可同時(shí)存在，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。2、試運(yùn)轉(zhuǎn)時(shí)出現(xiàn)的泄漏泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時(shí)高速旋轉(zhuǎn)產(chǎn)生的離心力，會(huì)減少介質(zhì)的泄漏。因此，試運(yùn)轉(zhuǎn)時(shí)機(jī)械密封泄漏在排除軸間及端蓋密封失效后，基本上都是由于動(dòng)、靜環(huán)摩擦副受破壞所致。引起摩擦副密封失效的因素主要有：1)、操作中，因抽空、氣蝕、憋壓等異?，F(xiàn)象，引起較大的軸向力，使動(dòng)、靜環(huán)接觸面分離。</p><p> 二）由于介質(zhì)引起的滲漏1.故障一：靜環(huán)和動(dòng)環(huán)的輔助密封件無彈性或者有的已經(jīng)腐爛，造成了機(jī)封的大量滲漏甚至有磨軸的現(xiàn)象。產(chǎn)生原因：高溫、污水中的弱酸、弱堿對(duì)靜環(huán)和動(dòng)環(huán)輔助橡膠密封件的腐蝕作用,造成了機(jī)械滲漏過大,動(dòng)、靜環(huán)橡膠密封圈材料為丁腈—40,不耐高溫,不耐酸堿,當(dāng)污水為酸性堿性時(shí)易腐蝕。解決方法：對(duì)腐蝕性介質(zhì),橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。2.故障二：真空固體顆粒雜質(zhì)引起的機(jī)械密封滲漏產(chǎn)生原因：固體顆粒進(jìn)入密封端面,會(huì)劃傷或加快密封端面的磨損,水垢和油污在軸(套)表面的堆積速度超過摩擦副的磨損速度,致使動(dòng)環(huán)不能補(bǔ)償磨耗位移,硬對(duì)硬摩擦副的運(yùn)轉(zhuǎn)壽命要比硬對(duì)石墨摩擦副的長,因?yàn)楣腆w顆粒會(huì)嵌入石墨密封環(huán)的密封面內(nèi)。解決方法：在固體顆粒容易進(jìn)入的位置應(yīng)選用碳化鎢對(duì)碳化鎢摩擦副的機(jī)械密封。03因其他問題引起的機(jī)械密封滲漏機(jī)械密封中還存在設(shè)計(jì)、選擇、安裝等不夠合理的地方。(1)彈簧壓縮量一定要按規(guī)定進(jìn)行,不允許有過大或過小的現(xiàn)象,誤差±2mm,壓縮量過大增加端面比壓,摩擦熱量過多,造成密封面熱變形和加速端面磨損,壓縮量過小動(dòng)靜環(huán)端面比壓不足,則不能密封。(2)安裝動(dòng)環(huán)密封圈的軸(或軸套)端面及安裝靜環(huán)密封圈的密封壓蓋。赤峰柳州酸王泵用機(jī)械密封。</p><div

漏油、漏水、漏氣）現(xiàn)象。這種現(xiàn)象輕則造成能量損失，以至降低或喪失工作能力，造成環(huán)境污染，重則可能造成嚴(yán)重事故。因此，防止"三漏"極為重要。流體漏損的原因可能由于密封裝置的裝配工藝不符合要求，也可能是由于密封件被磨損、變形、老化、腐蝕所至，而后者也往往與裝配因素（包括選用密封件材料、預(yù)緊程度、裝配位置等）有關(guān)。為此，在裝配工作中必須給以足夠的重視。1、選用密封材料要恰當(dāng)一般要根據(jù)不同的壓力、溫度、介質(zhì)選用。紙質(zhì)墊片只用于低壓、低溫條件；橡膠耐壓、耐溫能力也不高，且要考慮各種橡膠的不同性能，如耐油、耐酸、耐堿等；塑料的耐壓能力較好，但也不耐高溫；石棉強(qiáng)度較低，卻能耐高溫；金屬則兼有耐高溫、高壓的能力。2、合理裝配.要有合適的裝配緊度，并且壓緊要均勻。當(dāng)壓緊度不足時(shí)，會(huì)引起泄漏，或者在工作一段時(shí)間后，由于振動(dòng)及緊定螺釘被拉長而喪失緊度，導(dǎo)致泄漏；壓緊度過緊，對(duì)靜密封的墊片來講，會(huì)喪失彈力，引起墊片早期失效；對(duì)動(dòng)密封來講，會(huì)引起發(fā)熱、加速磨損、增大摩擦功率等不良后果。正確的緊度“○”型密封圈為例，其預(yù)緊變形度應(yīng)在8~30%之間。3、采用密封膠近年來采用液態(tài)密封膠進(jìn)行靜密封，已日益廣。HB65-50-60柳州酸王泵用機(jī)械密封。錫林郭勒HSW100-65-32BS柳州酸王泵用機(jī)械密封</p><p

雖然其主要的密封壓力依賴于填料盒本身的壓力，但彈簧和波紋管可補(bǔ)償液泵在起動(dòng)和停機(jī)過程中因主軸運(yùn)動(dòng)的壓力不足，使密封面始終保持一定的密封壓力。腐蝕磨損問題由于多種原因，例如包括軸承的公差、軸端余隙、振動(dòng)和主軸偏差，都會(huì)使液泵的主軸產(chǎn)生徑向和軸向運(yùn)動(dòng)。此外，由于將接觸面之間保持平行是十分困難的，因此機(jī)械密封本身的內(nèi)部產(chǎn)生移動(dòng)也是很正常的。這類移動(dòng)往往是由于設(shè)備和安裝公差、熱膨脹、管路應(yīng)力或主軸調(diào)試不當(dāng)所造成。為了使密封面之間始終保持互相配合，彈簧起到了機(jī)械密封與運(yùn)動(dòng)主軸之間的恒定調(diào)節(jié)作用。當(dāng)旋轉(zhuǎn)面和主軸之間采用人造橡膠密封時(shí)，該彈性體就會(huì)在主軸上來回運(yùn)動(dòng)。這種重復(fù)摩擦動(dòng)作，會(huì)磨蝕主軸上的防腐材料，失去主軸的氧化膜保護(hù)層，終會(huì)在主軸的摩擦面上形成磨損溝槽，造成液體從溝槽中泄漏，并增加必要的維修工作量或甚至更換主軸。為了解決這一問題，一般在填料盒內(nèi)安裝一個(gè)可更換的軸套。然而，解決腐蝕磨損問題的辦法是去除其內(nèi)部的動(dòng)態(tài)密封?，F(xiàn)在，大部分主要密封制造廠生產(chǎn)非腐蝕磨損型密封，以防止液泵零件的腐蝕磨損。平衡和非平衡式密封機(jī)械密封的平衡對(duì)接觸面的密封壓力有很大影響。揚(yáng)州HB50-50-50柳州酸王泵用機(jī)械密封</p><p
