機(jī)械磨損將引起密封副的正常配合關(guān)系被破壞，當(dāng)端面出現(xiàn)一定的磨損，傳動(dòng)軸每轉(zhuǎn)一轉(zhuǎn)密封件都要作軸向位移和徑向擺動(dòng)。根據(jù)磨損痕跡可以判斷運(yùn)動(dòng)和磨損情況，也可以確定密封泄漏的原因。例如，密封副磨損痕跡均勻，各零件的配合良好，這就說(shuō)明傳動(dòng)部分的同軸度良好。這時(shí)密封端面產(chǎn)生的泄漏，可能不是由密封本身問(wèn)題引起的。若泄漏量為常數(shù)，就意味著泄漏不是發(fā)生在兩端面之間，有可能發(fā)生在其他部位上，如靜密封處。再如，密封開(kāi)始使用時(shí)就泄漏，且觀察不到摩擦端面磨損痕跡，可能是旋轉(zhuǎn)環(huán)相對(duì)于靜止環(huán)不旋轉(zhuǎn)或打滑，其原因可能是防轉(zhuǎn)銷松脫或折斷，或是底座的孔徑小于密封件的外徑，由于安裝不到位所致。 </p><p> 盤(pán)根填料的形式和特點(diǎn) </p> <p> 隨著生產(chǎn)工藝的不斷出現(xiàn)，盤(pán)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(duì)密封的性能和受用壽命有著直接的影響。盤(pán)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(pán)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(gè)錠子在二軌道上運(yùn)行編織，在四角和中間沒(méi)有絨芯，編織的產(chǎn)品斷面為方形，其特點(diǎn)是盤(pán)根松散，但對(duì)軸振動(dòng)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(huì)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(gè)錠子在二軌道上編織，根據(jù)盤(pán)根規(guī)格決定套層，一般編織1~4層，中間沒(méi)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(méi)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。對(duì)于集裝式機(jī)械密封，出廠時(shí)已將機(jī)械密封壓縮量調(diào)整完畢，現(xiàn)場(chǎng)安裝時(shí)不允許解體機(jī)封。</p><div
