隨著生產(chǎn)工藝的不斷出現(xiàn)，盤根填料的編制形式也逐漸多樣化，根據(jù)使用條件和環(huán)境的不同，不同的編制形式對密封的性能和受用壽命有著直接的影響。盤根編制填料主要采用的編制形式有：發(fā)辮編織、套層編織、穿心編制、夾心編制等。盤根的編制形式和特點(diǎn)如下： </p> <p> 發(fā)辮編織 </p> <p> 發(fā)辮編織是用八個錠子在二軌道上運(yùn)行編織，在四角和中間沒有絨芯，編織的產(chǎn)品斷面為方形，其特點(diǎn)是盤根松散，但對軸振動和偏心用一定的補(bǔ)償作用，只用于小斷面填料，但斷面尺寸大將會出現(xiàn)填料外表花紋粗糙，結(jié)構(gòu)松弛，致密性差的缺點(diǎn) </p> <p> 套層編織 </p> <p> 套層編織是用8、12、16、24、36、48、60等個錠子在二軌道上編織，根據(jù)盤根規(guī)格決定套層，一般編織1~4層，中間沒有絨芯，套層填料致密性好，密封性強(qiáng)，但由于是套層，層間沒有纖維相連容易脫層，故多用于靜密封或低速設(shè)備。 </p> <p> 夾心編織 </p> <p> 夾心編制是以橡膠或金屬為芯子，纖維在外，一層套一層的編織，層數(shù)按需要而定，類似于套層編織，夾心編織致密性較好，強(qiáng)度高，彎曲性能好，密封性好，但與套層結(jié)構(gòu)一樣，表面層磨損后就容易脫落，一般用于泵、閥，極少用于往復(fù)設(shè)備。 </p><p> 按密封膠硫化方法分類 </p> <p> 此類密封膠系列利用空氣中的水分進(jìn)行硫化。它主要包括單組分的聚氨酯、硅橡膠和聚硫橡膠等。其聚合物基料中含有活性基因，能同空氣中的水發(fā)生反應(yīng)，形成交聯(lián)鍵，使密封膠硫化成網(wǎng)狀結(jié)構(gòu)。大氣中的濕氣作為硫化反應(yīng)中的催化劑。 </p> <p> 化學(xué)硫化型密封膠 </p> <p> 雙組分的聚氨酯、硅橡膠、聚硫橡膠、氯丁橡膠和環(huán)氧樹脂密封膠都屬于這一類，一般在室溫條件下完成硫化。某些單組分的氯磺化聚乙烯和氯丁橡膠密封膠以及聚氯乙烯溶膠糊狀密封膠（如汽車用點(diǎn)焊膠），則須在條件下經(jīng)化學(xué)反應(yīng)完成硫化。密封件必須存放在密封包裝內(nèi)，避免和空氣中的水分或塵埃接觸。</p><div

(2)磨軸的主要原因:①BIA型雙端面機(jī)械密封,反壓狀態(tài)是不良的工作狀態(tài),介質(zhì)中的顆粒、自吸式磁力泵雜質(zhì)很容易進(jìn)入密封面,使密封失效。②磨軸的主要件為橡膠波紋管,且是由于上端密封面處于不良潤滑狀態(tài),動靜環(huán)之間的摩擦力矩大于橡膠波紋管與軸之間的傳遞轉(zhuǎn)矩,發(fā)生相對轉(zhuǎn)動。③動、靜環(huán)輔助密封由于受到污水中的弱酸、弱堿的腐蝕,橡膠件已無彈性。有的已腐爛,失去了應(yīng)有的功能,產(chǎn)生了磨軸的現(xiàn)象。
