1）大多數(shù)潛污泵機械密封拆解后，靜環(huán)和動環(huán)的輔助密封件無彈性，有的已經(jīng)腐爛，造成了機封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對靜環(huán)和動環(huán)輔助橡膠密封件的腐蝕作用，造成了機械滲漏過大，動、靜環(huán)橡膠密封圈材料為丁腈—40，不耐高溫，不耐酸堿，當(dāng)污水為酸性堿性時易腐蝕。對策：對腐蝕性介質(zhì)，橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。（2）固體顆粒雜質(zhì)引起的機械密封滲漏如果固體顆粒進入密封端面，將會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，致使動環(huán)不能補償磨耗位移，硬對硬摩擦副的運轉(zhuǎn)壽命要比硬對石墨摩擦副的長，因為固體顆粒會嵌入石墨密封環(huán)的密封面內(nèi)。對策：在固體顆粒容易進入的位置應(yīng)選用碳化鎢對碳化鎢摩擦副的機械密封，南昌泵的機械密封。4、因其他問題引起的機械密封滲漏機械密封中還存在設(shè)計、選擇，南昌泵的機械密封、安裝等不夠合理的地方。（1）彈簧壓縮量一定要按規(guī)定進行，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，壓縮量過小動靜環(huán)端面比壓不足，南昌泵的機械密封，則不能密封。（2）安裝動環(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。合肥波紋管機械密封件。南昌泵的機械密封</p><div

O形圈、V形圈、U形圈、楔形圈和異形圈等）它主要起靜環(huán)和動環(huán)的密封作用，同時也起到浮動和緩沖作用。要求靜環(huán)的密封元件能保證靜環(huán)與壓蓋之間的密封性，靜環(huán)有一定的浮動性，動環(huán)的密封元件能保證動環(huán)與軸或軸套之間的密封性和動環(huán)的浮動性。材料要求耐熱等。1、基本結(jié)構(gòu)1）端面密封摩擦副2）緩沖補賞和壓緊機構(gòu)3）輔助密封（二級密封撓性元件）4）傳動機構(gòu)2、基本密封點1）端面主密封點2）靜環(huán)與端蓋輔助密封點3）動環(huán)與軸（軸套）輔助密封點4）端蓋與泵體連接密封點二、機械密封的優(yōu)缺點1、優(yōu)點（1）結(jié)構(gòu)可靠，泄漏量可以限制到很少，只要主密封面的表面粗糙度和平直度能保證達到要求，只要材料耐磨性好，機械密封可以達到很少泄漏量，甚至肉眼看不見泄漏。（2）壽命長。在機械密封中，主要磨損部分是密封摩擦副端面，因為密封端面的磨損量在正常工作條件下不大，一般可以連續(xù)使用1～2年，特殊場合下也有用到5～10年。（3）運轉(zhuǎn)中無需調(diào)整。由于機械密封靠彈簧力和流體壓力使摩擦副貼合，在運轉(zhuǎn)中自動保持接觸，裝配后就不用像普通軟填料那樣需調(diào)整壓緊。（4）具有耐耐振性。在轉(zhuǎn)速為3000r/min下**大振幅不超過（5）功率損失小。濰坊泵用機械密封合肥YM109機械密封件。</p><div

三、區(qū)分骨架油封型號C型骨架油封為內(nèi)骨架油封可分為SC型、TC型、VC型、KC型、DC型這五種，分別是單唇內(nèi)骨架油封、雙唇內(nèi)骨架油封、單唇無簧內(nèi)骨架油封、雙唇無簧內(nèi)骨架油封、雙唇雙簧內(nèi)骨架油封。G型骨架油封是外出有螺紋狀，其類型和C型一樣，只是在工藝上在外側(cè)修改成有螺紋狀，類似于O型圈的作用，即起到加強密封效果的作用，還能起到固定油封不松動。B型骨架油封是骨架內(nèi)側(cè)有膠料或者骨架內(nèi)外都沒有膠料，沒有膠料會讓散熱性能更好。A型骨架油封是裝配式油封，結(jié)構(gòu)相對上述三種相對復(fù)雜，特點是承壓性能更好更優(yōu)異。四、骨架油封的密封原理及應(yīng)用?骨架油封共分三部分：自緊彈簧、密封主體、加強骨架。?骨架油封的密封原理：由于在油封與軸之間存在著油封刃口控制的油膜，此油膜具有流體潤滑特性。?密封原理解析：骨架油封的作用下，油膜的剛度恰好使油膜與空氣接觸端形成一個新月面，防止了工作介質(zhì)的泄漏，從而實現(xiàn)旋轉(zhuǎn)軸的密封。油封的密封能力，取決于密封面油膜的厚度，厚度過大，油封泄漏；厚度過小，可能發(fā)生干摩擦，引起油封和軸磨損；密封唇與軸之間沒有油膜，則易引起發(fā)熱、磨損。因此，在安裝時，必須在密封圈上涂些油，同時保證骨架油封與軸心線垂直。</p><p> 同時無壓雙重機械密封外側(cè)密封就能在維修前起到密封和容納泄漏液體的作用。對一些有毒、含顆粒介質(zhì)(或腐蝕性相當(dāng)厲害的介質(zhì))，一般可考慮以下方法：(1)采用合適的環(huán)境控制措施，如外沖洗+帶旋風(fēng)分離器的管路沖洗系統(tǒng)。(2)采用有壓雙重機械密封。有壓雙重機械密封隔離液的壓力高于介質(zhì)壓力，因而泵送介質(zhì)不會進入密封腔。有壓雙重機械密封內(nèi)側(cè)密封起到阻止隔離液進入泵腔的作用。因此當(dāng)輸送諸如粘性、磨蝕性及高溫介質(zhì)時，有壓雙重機械密封內(nèi)側(cè)密封由于沒有暴露在介質(zhì)中，因此可以不用昂貴的合金制作。有壓雙重機械密封外側(cè)密封**起到不使隔離液漏入大氣的作用。3、平衡型機械密封和非平衡型機械密封機械密封密封腔中的壓力作用在動環(huán)上形成了閉合力，端面間的液膜形成開啟力。載荷系數(shù)K>1，密封為非平衡型機械密封。一般非平衡型機械密封只能用于低壓。當(dāng)壓力大于一定的限度，密封面間的液膜就會被擠出。在喪失液膜潤滑及高負荷的作用下，機械密封的密封端面會很快損壞。非平衡型機械密封不能平衡液體對端面的作用，端面比壓隨流體壓力的上升而上升。載荷系數(shù)K<1，密封為平衡型機械密封。無錫109-25機械密封件。</p><div

機械密封沖洗的目的在于防止雜質(zhì)集積，防止氣囊形成，保持和改善潤滑等，當(dāng)沖洗液溫度較低時，兼有冷卻作用。沖洗的方式主要有如下十八種：1方案：從泵的出口端沖洗內(nèi)機械密封腔。操作類似方案PLAN11。原因:密封腔冷卻，臥式泵的密封腔排氣，防止PLAN11方案外露管的凍結(jié)和流體結(jié)晶堵塞的危險。場合：普通密封腔，可能是ANSI/ASME泵，清潔常溫流體，用于單端面密封，很少用于雙斷面密封。維護：沖洗不能直接沖洗密封面，機封冷卻不能過度，根據(jù)通過內(nèi)截流管的揚程損失計算沖洗流量。2方案：無沖洗的封閉密封腔。原因：不需要流體二次循環(huán)。使用場合：常溫運轉(zhuǎn)下的大孔/開口密封腔，高溫運轉(zhuǎn)下的冷卻套密封腔，清潔流體，干式密封的直立/頂入式混和器/攪拌器，維護：流程必須有足夠的沸點臨界空間，避免汽化，在熱運轉(zhuǎn)條件下，密封腔套內(nèi)可能需要一直有冷卻液體，臥式設(shè)備必能自己排氣，經(jīng)常和冷卻方案PLAN62聯(lián)合使用。3方案：從泵出口處經(jīng)過限流孔板進行機械密封沖洗，違反單端面機械密封沖洗方案。原因：密封腔的冷卻，臥式密封腔的排氣，增加密封腔的壓力和流體汽化臨界空間。場合：通常用于清潔流體，清潔、非聚合流體。維護：使用孔徑為。蕪湖YM109機械密封件。上海機械密封大全</p><p

機械密封的作用:一、提高機器效率、降低能耗。1、減少機器的內(nèi)漏、外漏和穿漏，提高機器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機械密封，使泵效率提高。2、減少摩擦損失，提高機器的機械效率。例如，將雙端面密封改為單端面密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失，提高機械效率。3、改變密封方式，提高機器或機組的效率。例如，將屏蔽泵改用機械密封泵，使電動機效率提高;采用磁力傳動泵，提高機器效率。4、改變輔助系統(tǒng)，減少能耗，提高機組效率。例如，熱油泵自沖洗改為小葉輪循環(huán)沖洗;雙端面密封改為單端面密封，節(jié)省封油輔助系統(tǒng)的能耗。二、節(jié)約原材料。例如，工藝流體回收，減少或消除動力蒸汽和工藝流體的損耗，減少封油損耗等。三、提高機器可靠性。例如，軸封的漏損和壽命決定軸封和機器的可靠性。四、安全和環(huán)境保護。根據(jù)日本某廠調(diào)查報告，在發(fā)生的786件事故中有32件是泄漏造成的(占42%)。此外工藝流體泄漏還會造成環(huán)境污染，包括對大氣污染、水污染和車間環(huán)境污染。機械密封的意義:一、密封技術(shù)雖然不是領(lǐng)先性技術(shù)，但卻是決定性技術(shù)。例如，美國挑戰(zhàn)號航天飛機由于密封事故而墜落。南昌泵的機械密封</p><p
