其抗拉強度和硬度增加而韌性下降.塑料和橡膠的低溫性能比金屬材料更為敏感.一般情況下，塑料和橡膠只能在-50℃以上的溫度范圍使用。對于低溫泵，資料[13]介紹:丁睛橡膠的使用溫度限為-60℃氯丁橡膠為-65℃，硅酮橡膠為-80℃，氟化橡膠為-45℃，聚四氟乙烯為-79℃，并認為使用以上這些材料作填料的機械密封以-70℃為使用極限。如果介質(zhì)溫度在-70℃以下，則使用波紋管型機械密封或者雙端面機械密封.資料[6]介紹聚四氟乙烯在氦的沸點(℃)還能保持一點柔軟性，適宜做低溫材料，但聚四氟乙烯的膨脹系數(shù)大，所以在-50~-100℃溫度使用時，常采用四氟填充石墨或玻璃纖維，而不用純四氟材料.此外，在低溫時，V形圈裝到軸套上后，動環(huán)往往不能浮動。因此，要注意V形圈的組裝尺寸。關(guān)于低溫機械密封及低溫泵材料如表10-4所示。低溫時PTFE的機械性能如表10-5所示。2.結(jié)構(gòu)要求在一般的0~-50℃低溫下，常采用單端面機械密封，有非平衡或平衡型結(jié)構(gòu)，但多數(shù)選用平衡型結(jié)構(gòu)，這是因為密封端面的液休經(jīng)摩擦后溫度升高，液膜壓力隨之升高而將密封面推開，泄漏加劇。因此，低溫時的端面比壓要選高值。在液溫低于-70℃時，則采用波紋管密封或雙端面密封.不過使用雙端面密封時。山東紙漿泵用機械密封北京脫硫泵用機械密封型號。</p><div

單端面密封離心泵、雙端面密封離心泵后期的維護費用大概為屏蔽泵的2倍。綜上所述，單端面密封離心泵、雙端面密封離心泵、屏蔽泵在輸送甲醇危險物料時，安全性及經(jīng)濟性比較如下表3-1所示：表3-1：安全性及經(jīng)濟性比較分析表序號設(shè)備名稱軸封特點泄漏特性安全性經(jīng)濟性1單端面密封離心泵旋轉(zhuǎn)軸密封/一對摩擦副密封端面機封泄漏介質(zhì)直接泄漏到環(huán)境中一般設(shè)備投資低/維護高2雙端面密封離心泵旋轉(zhuǎn)軸密封/兩對摩擦副密封端面內(nèi)機封泄漏會先泄漏到外級機封，只有內(nèi)外兩級機封都泄漏時，介質(zhì)才會泄漏到環(huán)境中。良設(shè)備投資中/維護高3屏蔽泵無旋轉(zhuǎn)軸密封/無泄漏無泄漏優(yōu)設(shè)備投資高/維護低在石油、化工裝置對泵的要求，必須滿足對介質(zhì)特性的要求，要充分考慮輸送介質(zhì)的特性，工況環(huán)境的特點，安全環(huán)保的要求及經(jīng)濟成本進行綜合考慮。安全優(yōu)先，經(jīng)濟性為本。一般的場合，優(yōu)先選用單端面密封，因為單端面密封結(jié)構(gòu)簡單、使用方便、價格低。但在以下特殊的場合，就要嚴格按照要求選擇：（1）對輸送易燃、易爆、易揮發(fā)的低溫介質(zhì)（液化石油氣等）、有毒或貴介質(zhì)的泵要求軸封可靠或采用無泄漏泵。應(yīng)優(yōu)先選用無泄漏泵，如屏蔽泵、磁力泵或帶有泄漏液收集和泄漏報警裝置的雙重機封密封。因此。</p><p> 機泵裝置中，機動設(shè)備的機械密封約占整個動密封數(shù)量的80%-85%。而在機泵故障中，機械密封的故障大約占整個維修工作量的一半。可見機械密封在機泵維修中所占的位置。由于機泵所輸送的介質(zhì)千差萬別，工藝條件各不相同，所以了解這些情況對機封的選擇及維護很重要。結(jié)合多年來在機封選擇和維修中的經(jīng)驗，介紹幾種特殊工況下機械密封的工作特點和注意事項。一、高溫下的機械密封一般情況下，介質(zhì)的溫度超過120℃即認為是高溫密封。此時機械密封存在的主要問題有：(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，由于長時間在高溫環(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)高溫會加劇金屬材料的腐蝕，縮短機封的使用壽命。為保證機械密封在高溫環(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。天津格蘭富泵用機械密封型號。</p><div

5）、介質(zhì)中腐蝕性、聚合性物質(zhì)增多；（6）、環(huán)境溫度急劇變化；（7）、工況頻繁變化或調(diào)整；離心泵在正常運轉(zhuǎn)中突然泄漏，如不能及時發(fā)現(xiàn)，往往會釀成較大事故或損失，須予以重視并采取有效措施。4、泵用機械密封檢修中的幾個誤區(qū)、彈簧壓縮量越大密封效果越好其實不然，彈簧壓縮量過大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損；過度的壓縮使彈簧失去調(diào)節(jié)動環(huán)端面的能力，導(dǎo)致密封失效。、動環(huán)密封越緊越好其實動環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，泄漏；二是增大了動環(huán)軸向調(diào)整、移動的阻力，在工況變化頻繁時無法適時進行調(diào)整；三是彈簧過度疲勞易損壞；四是使動環(huán)密封圈變形，影響密封效果。、靜環(huán)密封圈越緊越好靜環(huán)密封圈基本處于靜止?fàn)顟B(tài)，相對較緊密封效果會好些，但過緊也是有害的。一是引起靜環(huán)密封因過度變形，影響密封效果；二是靜環(huán)材質(zhì)以石墨居多，一般較脆，過度受力極易引起碎裂；三是安裝、拆卸困難，極易損壞靜環(huán)。、葉輪鎖母越緊越好機械密封泄漏中，軸套與軸之間的泄漏（軸間泄漏）是比較常見的。一般認為，軸間泄漏就是葉輪鎖母沒鎖緊，其實導(dǎo)致軸間泄漏的因素較多，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差。江西飛力泵用機械密封型號。樂陵雙端面泵用機械密封</p><p
