style="text-indent:25px">軸封（shaftseal）一種摩擦密封或填料函，用以防止壓縮機(jī)或其他流體輸送設(shè)備軸與軸承之間的液體泄漏。軸封是防止泵軸與殼體處泄漏而設(shè)置的密封裝置常用的軸封型式有填料密封、機(jī)械密封和動(dòng)力封。往復(fù)泵的軸封通常是填料密封。當(dāng)輸送不允許泄漏介質(zhì)時(shí)，可采用隔膜式往復(fù)泵。旋轉(zhuǎn)式泵(含葉片式泵、轉(zhuǎn)子泵等)的軸封主要有填料密封、機(jī)械密封和動(dòng)力密封。填料密封填料密封結(jié)構(gòu)簡單、價(jià)格便宜、維修方便。但泄漏量大、功耗損失大。因此填料密封用于輸送一般介質(zhì)，如水等;一般不適用于石油及化工介質(zhì)，特別是不能用在貴重、易爆和有危害介質(zhì)中。機(jī)械密封機(jī)械密封(也稱端面密封)的密封效果好，泄漏量很小，壽命長，但價(jià)格貴，加工安裝維修保養(yǎng)比一般密封要求高。機(jī)械密封適用于輸送石油及化工介質(zhì)，可用于各種不同粘度、強(qiáng)腐蝕性和含顆粒的介質(zhì)。美國石油學(xué)會(huì)標(biāo)準(zhǔn)API610(第8版)規(guī)定:除用戶有規(guī)定外，應(yīng)當(dāng)裝備集裝式機(jī)械密封。淮安中型機(jī)械密封生產(chǎn)廠家人們在分析機(jī)械密封泄漏原因時(shí)，在機(jī)械封自身方面查找原因，比如：它的選型如是否合適，材料選擇是否正確。</p><div

style="text-indent:25px">化學(xué)腐蝕由于密封接觸腐蝕性介質(zhì)就會(huì)產(chǎn)生表面腐蝕，甚至在表面各處產(chǎn)生劇烈腐蝕點(diǎn)而形成點(diǎn)蝕。在金屬的晶界上產(chǎn)生的晶間腐蝕，會(huì)深入到金屬的內(nèi)部，并進(jìn)一步破壞而引起斷裂。腐蝕的性能影響很大。由于密封件比主機(jī)的零件小，而且更精密，通常要選用比主機(jī)更耐腐蝕的材料。經(jīng)驗(yàn)表明，壓力、溫度和滑動(dòng)速度都能使腐蝕加速。密封件的腐蝕率隨溫度升高呈指標(biāo)規(guī)律增加。處理強(qiáng)腐蝕流體時(shí)，采用雙端面密封，可以比較大限度減輕腐蝕對密封件的影響，因?yàn)樗c工藝流體相接觸的零件數(shù)量少。這也是在強(qiáng)腐蝕條件下，選擇密封結(jié)構(gòu)的一條重要的原則。密封零件失效機(jī)械密封零件失效大部分是輔助密封圈失效，機(jī)械密封由于泄漏而不能正常工作的一個(gè)主要原因也是因?yàn)镺形圈失效引起的。O形圈失效的表現(xiàn)為老化、長久性變形、溶脹變形、扭曲及擠出損傷。因此，在選用O形圈時(shí)應(yīng)考慮合成橡膠的安全使用溫度，盡可能地選用截面較大的橡膠O形圈，適當(dāng)提高硬度，采用溝槽式的裝配結(jié)構(gòu)，通過沉浸試驗(yàn)合理選材，必要時(shí)選用復(fù)合材料，如橡膠包覆聚四氟乙烯密封圈。</p><p> 機(jī)械密封的安裝前準(zhǔn)備工作及注意事項(xiàng) </p> <p> 以上檢修工作完成后，需要重新安裝機(jī)封，在安裝前先必須做好準(zhǔn)備工作： </p> <p> 1、如果更換新機(jī)封，須檢查機(jī)械密封的型號、規(guī)格是否正確，質(zhì)量是否符合標(biāo)準(zhǔn)； </p> <p> 2、靜環(huán)尾部防轉(zhuǎn)槽端與防轉(zhuǎn)銷頂部應(yīng)保持1mm-2mm的軸向間隙，以免緩沖失效； </p> <p> 3、動(dòng)、靜環(huán)端面用酒精清洗干凈，其余金屬件用汽油清洗并用潔凈的壓縮空氣吹干，仔細(xì)檢查務(wù)心保證動(dòng)、靜環(huán)密封面沒有任何損傷。裝配前，兩件“0”形橡膠密封圈應(yīng)涂上一層潤滑油膏，動(dòng)、靜環(huán)端面不許涂油。 </p> <p> 機(jī)械密封的安裝 </p> <p> 機(jī)封安裝順序及注意事項(xiàng)如下： </p> <p> 1、在轉(zhuǎn)子與泵體的相對位置固定之后，確定機(jī)械密封的安裝位置，根據(jù)密封的安裝尺寸及靜環(huán)在壓蓋中的位置，測算出密封在軸或軸套上的定位尺寸； </p> <p> 2、安裝機(jī)封動(dòng)環(huán)，動(dòng)環(huán)安裝后須保證能其在軸上靈活移動(dòng)； </p> <p> 3、將組裝好的靜環(huán)部分和動(dòng)環(huán)部分組裝好； </p> <p> 4、把密封端蓋裝在密封體內(nèi)，并將螺絲擰緊。對于含有固體顆粒介質(zhì)，密封面進(jìn)入固體顆粒是導(dǎo)致使密封失效的主要原因。</p><div style="width:100%;text-align: center;"><img style="max-width:
