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(jiǎn)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(zhǎng)，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(guó)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。</p><p>

高壓密封的型式很多，按其工作原理分為強(qiáng)制密封和自緊密封兩類。強(qiáng)制密封是依靠聯(lián)接件（螺栓）的預(yù)緊力來保證壓力容器的頂蓋、密封元件和圓筒體端部之間具有一定的接觸壓力，以達(dá)到密封的目的。自緊密封是隨著壓力容器內(nèi)的操縱壓力增加，密封元件與頂蓋、圓筒體端部之間的接觸壓力也隨之增加，由此實(shí)現(xiàn)密封作用。自緊密封的特點(diǎn)是壓力越高，密封元件在接觸面的壓緊力就越大，密封性能也就越好，操縱條件波動(dòng)時(shí)，密封仍然可靠。但是結(jié)構(gòu)比較復(fù)雜，制造較困難。自緊密封按密封元件變形方式還可以分為軸向自緊密封和徑向自緊密封。 </p> <p> 按密封材料性能，高壓密封又可分為使密封元件產(chǎn)生塑性變形的塑性密封，使密封元件產(chǎn)生彈性變形的彈性密封。化工泵運(yùn)轉(zhuǎn)中可實(shí)現(xiàn)滴水不漏，因此在化工泵輸送含雜質(zhì)介質(zhì)的泵上經(jīng)常采用。蘇州中型密封中間商</p><p
