有時密封介質(zhì)本身就是各種懸浮漿液，這些介質(zhì)中的顆粒對密封起著磨料作用.高粘度介質(zhì)常指粘度大于Pa·s(700cP)的介質(zhì).一、含有磨料介質(zhì)的機械密封實際生產(chǎn)中經(jīng)常遇到液一固兩相或氣一固兩相介質(zhì)的密封問題，而機械密封的大敵是含有固體顆粒的溶液.磨料介質(zhì)包含以下幾種情況:1.處理物料是漿液;2.在機體和管線內(nèi)有雜質(zhì)混人;3.由于溫度變化有結(jié)晶析出或有凝固物產(chǎn)生;4.在密封端面內(nèi)有溶解物析出;5.由于化學反應有固體物質(zhì)產(chǎn)生;6.由于電化學作用在密封端面內(nèi)析出和附著金屬物質(zhì).普通單端面機械密封遇到磨料介質(zhì)時產(chǎn)生下列故璋:1.密封端面早期磨損;2.動環(huán)因間隙阻塞和密封圈摩擦力增大而不能動作;3.密封圈不能起緩沖作用;4.彈簧被雜質(zhì)阻塞不能動作;5.軸不能旋轉(zhuǎn);6.整個密封失效.對含磨料介質(zhì)的密封應采取以下措施:1.加強沖洗冷卻措施，防止雜質(zhì)在密封腔內(nèi)淤塞，如單端面密封應加注液潤滑，雙端面密封則加阻封液或阻封液和輔助注液合用;2.摩擦副材料選用硬對硬配合，常用硬質(zhì)合金對硬質(zhì)合金(或陶瓷);3.盡童采用大彈簧，減少顆粒阻塞機會；4.如用波紋管密封代替普通機械密封，建議用橡膠波紋管和焊接金屬經(jīng)過噴涂或合成橡膠包夜的波紋管，因為一般金屬波紋管對處理砂漿液能力差。云南循環(huán)泵用機械密封哪家好德陽渣漿泵用機械密封泄露。</p><div

以及正確選擇潤滑、沖洗、保溫、冷卻等機械密封循環(huán)保護系統(tǒng)等。4.根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。二、機械密封的安裝與使用要求1.機械密封對機器精度的要求(以泵用機械密封為例)(1)安裝機械密封部位的軸(或軸套)的徑向跳動公差不超過～。(2)轉(zhuǎn)子軸向竄動不超過。(3)密封腔體與密封端蓋結(jié)合的定位端面對軸(或軸套)表面的跳動公差不超過～。2.密封件的確認(1)確認所安裝的密封是否與要求的型號一致。(2)安裝前要仔細地與總裝圖對照，零件數(shù)量是否齊全。(3)采用并圈彈簧傳動的機械密封，其彈簧有左、右旋之分，須按轉(zhuǎn)軸的旋向來選擇。3.安裝安裝方法隨機械密封型式、機器的種類不同而有所不同，但其安裝要領(lǐng)幾乎都相同，安裝步驟和注意事項如下：(1)安裝尺寸的確定安裝時，應按產(chǎn)品的使用說明書或樣本，保證機械密封的安裝尺寸。(2)裝入前，軸(軸套)、壓蓋應無毛刺，軸承狀況良好;密封件、軸、密封腔、壓蓋都應該清洗干凈。為減少摩擦阻力，軸上安裝機械密封的部位要薄薄地涂上一層油，以進行潤滑，考慮到橡膠O形圈的相溶性，若不宜用油，可涂肥皂水。浮裝式靜環(huán)不帶防轉(zhuǎn)銷的結(jié)構(gòu)，不宜涂油，應干式裝入壓蓋。。</p><p> 機械密封是一種旋轉(zhuǎn)機械的軸封裝置，機械密封又叫端面密封，在國家有關(guān)標準中是這樣定義的:"由至少一對垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補償機構(gòu)彈力(或磁力)的作用以及輔助密封的配合下保持貼合并相對滑動而構(gòu)成的防止流體泄漏的裝置"。常用機械密封結(jié)構(gòu)由靜止環(huán)(靜環(huán))、旋轉(zhuǎn)環(huán)(動環(huán))、彈性元件彈簧座、緊定螺釘、旋轉(zhuǎn)環(huán)輔助密封圈和靜止環(huán)輔助密封圈等元件組成，防轉(zhuǎn)銷固定在壓蓋上以防止靜止環(huán)轉(zhuǎn)動。機械密封在日常檢修中，常常會存在以下幾個誤區(qū)：誤區(qū)一：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，導致密封失效。誤區(qū)二：動環(huán)密封圈越緊越好？！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。誤區(qū)三：靜環(huán)密封圈越緊越好？！靜環(huán)密封圈基本處于靜止狀態(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。德陽循環(huán)泵用機械密封泄露。</p><div

硬環(huán)的材質(zhì)種類很多（見“27”）。只有在特殊情況下，如介質(zhì)中含有固體顆粒、有結(jié)晶析出或高粘度流體中才選用硬對硬的配對。當選用一軟一硬的配對時硬環(huán)端面的寬度比軟環(huán)寬，在硬對硬的材質(zhì)中可不受此限制。為減少泄漏量和機械雜質(zhì)進入密封端面的可能性，盡量采用內(nèi)裝內(nèi)流式密封結(jié)構(gòu)S選擇導熱性良好的材料做動環(huán)，以散出較多的熱量，降低密封端面的溫度。為保證密封環(huán)的整體強度和剛度，環(huán)的壁厚不可太薄。對于導熱性良好的材料，增加環(huán)厚有利散熱；對于導熱性欠佳的材料厚度可小些。對于所受壓力較高的密封環(huán)，要從力學角度另行設計，必要時采取加固措施。環(huán)的形狀要軸對稱，以減少其不對稱的機械變形和熱變形。動環(huán)做補償環(huán)時，例如國產(chǎn)104和B104型密封（圖13、圖14），動環(huán)和軸（軸套）的（直徑）間隙為0．40～0．60mm，以防止動環(huán)在工作中卡住而失去補償能力；靜環(huán)內(nèi)徑要比軸（軸套）大l～2mm，避免兩者摩擦。密封端面的寬度是個重要參數(shù)，要綜合考慮。三、密封端面的寬度要考慮的因素密封端面的寬度一般是首先決定軟面的寬度，硬面寬度自不待說。泄漏量與端面寬度關(guān)系不大。但是，從產(chǎn)生的摩擦熱量來說窄一些較好，產(chǎn)生的熱量較少，溫度梯度小，熱變形也小。吉林襄樊五二五泵用機械密封型號。云南循環(huán)泵用機械密封哪家好</p><p

當產(chǎn)生抽空（汽蝕）時，靜環(huán)能離位，從而損壞密封。2）固定型靜環(huán)。圖21所示為幾種固定型靜環(huán)，這種靜環(huán)由于浮動性差，安裝時尤其要注意密封端面和軸心線的垂直度。其優(yōu)點是泵抽空時靜環(huán)不至于離位，較為可靠。3）粘結(jié)型靜環(huán)。上兩種靜環(huán)安裝在壓蓋中時都設有密封圈，而粘結(jié)型靜環(huán)則取消了密封圈，靜環(huán)與壓蓋之間的密封和防轉(zhuǎn)，用粘結(jié)劑實現(xiàn)。由于采用了粘結(jié)劑，使用溫度和介質(zhì)受到了粘結(jié)劑性能的限制，盡管如此，仍在很多場合得到應用。集裝式密封的軸套的傳動普通機械密封的軸套都是事先安裝和固定在軸上后再安裝機械密封，而集裝式密封則不同，它是將密封軸套和壓蓋預先裝在軸套上，再整體向軸上安裝，于是存在一個軸套如何固定在軸上，并傳遞扭矩的問題，同時還要解決軸套和軸之間的泄漏問題。圖42a表示了一種傳動方式。螺釘安裝在零件A上，在軸套的對應部位開有圓孔，將螺釘通過軸套的圓孔，并旋緊在軸上，即可實現(xiàn)軸套和軸的傳動。軸套和軸的密封，靠O形圈來完成。這種傳動方式比較簡單。圖42b是另一種傳動方式。它用圓螺母A壓緊軸和軸套之間的填料（四氟制成），靠填料與軸的摩擦力來傳動，同時也起到了密封圈的作用。重慶雙端面泵用機械密封</p><p
