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(lái)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(rùn)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(rùn)滑性差，端面摩擦產(chǎn)生的熱量較多，滄州LCF50/210I襄樊五二五機(jī)械密封，滄州LCF50/210I襄樊五二五機(jī)械密封，若不能及時(shí)轉(zhuǎn)移，必然會(huì)加劇端面處的氣化，滄州LCF50/210I襄樊五二五機(jī)械密封，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，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、改進(jìn)密封結(jié)構(gòu)及正確選擇摩擦副材料。實(shí)踐證明。襄樊五二五機(jī)械密封HTM-85D351。滄州LCF50/210I襄樊五二五機(jī)械密封</p><div

在機(jī)械密封水泵的常見(jiàn)故障中，機(jī)械密封的故障大約占整個(gè)維修工作量的一半?？梢?jiàn)機(jī)械密封在機(jī)泵維修中所占的位置。由于機(jī)泵所輸送的介質(zhì)千差萬(wàn)別，工藝條件各不相同，所以了解這些情況對(duì)機(jī)封的選擇及維護(hù)很重要。結(jié)合多年來(lái)在機(jī)封選擇和維修中的經(jīng)驗(yàn)，介紹幾種特殊工況下機(jī)械密封的工作特點(diǎn)和注意事項(xiàng)。一、高溫下的機(jī)械密封一般情況下，介質(zhì)的溫度超過(guò)120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問(wèn)題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長(zhǎng)時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會(huì)加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。為保證機(jī)械密封在高溫環(huán)境下正常工作，可以采取如下措施：1、給機(jī)封增加冷卻沖洗裝置。2、選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成。LCF50/210襄樊五二五機(jī)械密封。南昌IH-25S襄樊五二五機(jī)械密封</p><p

機(jī)械密封是靠一對(duì)或數(shù)對(duì)垂直于軸作相對(duì)滑動(dòng)的端面在流體壓力和補(bǔ)償機(jī)構(gòu)的彈力（或磁力）作用下保持貼合并配以輔助密封而達(dá)到阻漏的軸封裝置。水泵常用機(jī)械密封結(jié)構(gòu)如圖所示。由靜止環(huán)（靜環(huán)）1、旋轉(zhuǎn)環(huán)（動(dòng)環(huán)）2、彈性元件3、彈簧座4、緊定螺釘5、旋轉(zhuǎn)環(huán)輔助密封圈6和靜止環(huán)輔助密封圈8等元件組成，防轉(zhuǎn)銷7固定在壓蓋9上以防止靜止環(huán)轉(zhuǎn)動(dòng)。旋轉(zhuǎn)環(huán)和靜止環(huán)往往還可根據(jù)它們是否具有軸向補(bǔ)償能力而稱為補(bǔ)償環(huán)或非補(bǔ)償還。機(jī)械密封中流體可能泄漏的途徑有如圖1中的A、B、C、D四個(gè)通道。C、D泄漏通道分別是靜止環(huán)與壓蓋、壓蓋與殼體之間的密封，二者均屬靜密封。B通道是旋轉(zhuǎn)環(huán)與軸之間的密封，當(dāng)端面摩擦磨損后，它**能追隨補(bǔ)償環(huán)沿軸向作微量的移動(dòng)，實(shí)際上仍然是一個(gè)相對(duì)靜密封。因此，這些泄漏通道相對(duì)來(lái)說(shuō)比較容易封堵。靜密封元件常用的有橡膠O形圈或聚四氟乙烯V形圈，而作為補(bǔ)償環(huán)的旋轉(zhuǎn)環(huán)或靜止環(huán)輔助密封，有時(shí)采用兼?zhèn)鋸椥栽δ艿南鹉z、聚四氟乙烯或金屬波紋管的結(jié)構(gòu)。A通道則是旋轉(zhuǎn)環(huán)與靜止環(huán)的端面彼此貼合作相對(duì)滑動(dòng)的動(dòng)密封，它是機(jī)械密封裝置中的主密封，也是決定機(jī)械密封性能和壽命的關(guān)鍵。因此，對(duì)密封端面的加工要求很高。滄州LCF50/210I襄樊五二五機(jī)械密封</p><p
