由介質(zhì)壓力變化引起端面比壓的增量大于或等于介質(zhì)壓力的增量。平衡型：載荷系數(shù)K<1的密封，也就是由介質(zhì)壓力變化引起的端面比壓的增量小于介質(zhì)壓力的增量，稱為平衡型密封。根據(jù)密封端面的數(shù)量和布置方式可分為單端面、雙端面及多端面機(jī)械密封。兩組密封端面“背靠背”（圖10a）或“面對(duì)面”（圖10b）布置的密封叫雙端面機(jī)械密封。對(duì)于工作介質(zhì)有毒、易爆、易燃、易揮發(fā)、易結(jié)晶、高溫、低溫或工作介質(zhì)是氣體，福州安德里茲泵用機(jī)械密封，或?qū)τ诟哒婵斩鹊拿芊?，可用雙端面密封。此時(shí)雙端面之間的密封腔引入封液進(jìn)行堵封、潤(rùn)滑和冷卻，福州安德里茲泵用機(jī)械密封。一般情況下封液選用潔凈和潤(rùn)滑性好的介質(zhì)。二、串聯(lián)機(jī)械密封應(yīng)用的工況兩組或兩組以上同向布置的單端面機(jī)械密封組成串聯(lián)機(jī)械密封（圖11）。這種密封方式使密封腔的壓力逐級(jí)降低，介質(zhì)不至外漏。串聯(lián)密封一般情況下很少采用，只有在壓力很高時(shí)采用。補(bǔ)償機(jī)構(gòu)為波紋管，密封環(huán)（動(dòng)環(huán)或靜環(huán)）和波紋管制成一個(gè)整體，福州安德里茲泵用機(jī)械密封，中間沒有輔助密封圈（見圖8）稱為波紋音式機(jī)械密封。波紋音式機(jī)械密封減少了一個(gè)泄漏點(diǎn)；同時(shí)減少了補(bǔ)償機(jī)構(gòu)的摩擦阻力，改善了追隨性；對(duì)于焊接金屬波紋管密封（圖8b）使用溫度不受輔助密封圈的限制；對(duì)于四氟波紋管密封（圖8a）可用于腐蝕性介質(zhì)中。河?xùn)|區(qū)安德里茲泵用機(jī)械密封25-LP-D-S32-D20/60-DE。福州安德里茲泵用機(jī)械密封</p><div

九、波紋管式機(jī)械密封波紋管式機(jī)械密封的應(yīng)用范圍很廣，從低溫到高溫，從中性介質(zhì)到腐蝕性介質(zhì)，從低速到高速，從普通到苛刻的工作條件都可選用。所有這些可通過變更波紋管的幾何形狀（如內(nèi)外徑、波片厚度和波數(shù)等）與材料彈性模量，改變波紋管的彈率。根據(jù)介質(zhì)的腐蝕性能，選用不同的波紋管材料等。例如對(duì)工作壓力和溫度都不高的中性介質(zhì)（油和水等），可選用橡膠制造的簡(jiǎn)易波紋管密封；在腐蝕性介質(zhì)中（酸或減等），可選用四氟制造的波紋管密封；高溫和高速下，可采用焊接金屬波紋管機(jī)械密封等。焊接金屬波紋管密封的特點(diǎn)焊接金屬波紋管機(jī)械密封用的波紋管是由軋制的金屬薄板沖裁成環(huán)形波紋狀的型面，波形多采用S形，將許多個(gè)波片重疊起來，分別在環(huán)形的外緣和內(nèi)緣進(jìn)行焊接，組成一個(gè)波紋管，兩端再與傳動(dòng)座和動(dòng)環(huán)焊接成整體。除了不用輔助密封圈外，還具備使用溫度范圍廣的特點(diǎn)，**高可達(dá)600度，**低可到一200度。此外高速下對(duì)軸的振動(dòng)和振擺適應(yīng)性較強(qiáng)，有很好的補(bǔ)償能力，保證密封端面良好地貼合。但是長(zhǎng)期在高溫下工作的焊接金屬波紋管密封，波紋管的彈率有減小的趨勢(shì)（俗稱“失彈”），使用受到一定的限制。</p><p> 影響動(dòng)環(huán)的軸向浮動(dòng)和彈簧的補(bǔ)償。④檢查緊定螺釘是否松動(dòng)，是否影響機(jī)械密封的正常工作狀態(tài)。⑤檢查固定端蓋的螺釘是否松動(dòng)，而引起密封端蓋的偏斜。⑥檢查泵的軸向竄動(dòng)和徑向振動(dòng)是否超過使用的技術(shù)要求。⑦若是裝軸套的情況，檢查軸套與軸之間的密封是否損壞，位置是否正確。⑧檢查密封體內(nèi)有無密封液循環(huán)，機(jī)械密封是否處于干摩擦狀態(tài)。機(jī)械密封件的選型方法和使用要求機(jī)械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機(jī)械基礎(chǔ)元件之一，是各種泵類、反應(yīng)合成釜、透平壓縮機(jī)、潛水電機(jī)等設(shè)備的關(guān)鍵部件。其密封性能和使用壽命取決于許多因素，如選型、機(jī)器的精度、正確的安裝使用等。一、選型方法機(jī)械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機(jī)械密封，耐高壓、耐腐蝕機(jī)械密封，耐顆粒介質(zhì)機(jī)械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機(jī)械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機(jī)械密封。選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。選型的基本原則為：1.根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。2.根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動(dòng)壓式或非接觸型。貴陽(yáng)安德里茲泵用機(jī)械密封JCS1C-43-QREO-GA-192038。</p><div

機(jī)泵裝置中，機(jī)動(dòng)設(shè)備的機(jī)械密封約占整個(gè)動(dòng)密封數(shù)量的80%-85%。而在機(jī)泵故障中，機(jī)械密封的故障大約占整個(gè)維修工作量的一半?？梢姍C(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120℃即認(rèn)為是高溫密封。此時(shí)機(jī)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(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。SE2-58-QREG-304081安德里茲泵用機(jī)械密封。太原11-LP-D-S32-D20/30-DE安德里茲泵用機(jī)械密封</p><p

二、泵用機(jī)械密封檢修中的幾個(gè)誤區(qū)1．彈簧壓縮量越大密封效果越好。其實(shí)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(dòng)環(huán)端面的能力，導(dǎo)致密封失效。2．動(dòng)環(huán)密封圖越緊越好。其實(shí)動(dòng)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(dòng)環(huán)軸向調(diào)整、移動(dòng)的阻力，在工況變化頻繁時(shí)無法適時(shí)進(jìn)行調(diào)整；三是彈簧過度疲勞易損壞；四是使動(dòng)環(huán)密封圈變形，影響密封效果。3．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(duì)較緊密封效果會(huì)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)。4．葉輪鎖母越緊越好。機(jī)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(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實(shí)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，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長(zhǎng)等都會(huì)導(dǎo)致軸間泄漏。鎖母鎖緊過度只會(huì)導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性。福州安德里茲泵用機(jī)械密封</p><p
