外密封的安裝方式是將靜態(tài)密封面的方向顛倒過(guò)來(lái)，主軸上的旋轉(zhuǎn)單元位于填料盒壓蓋的外面。外密封主要具有以下五大好處：</span> </p> <p> 安裝容易; </p> <p> 費(fèi)用相對(duì)較低; </p> <p> 可以連續(xù)監(jiān)控和清潔; </p> <p> 適于無(wú)法在內(nèi)部安裝密封的很小填料盒; </p>

泵用機(jī)械密封種類(lèi)繁多，型號(hào)各異，但泄漏點(diǎn)主要有：①軸套與軸間的密封；②動(dòng)環(huán)與軸套間的密封；③動(dòng)、靜環(huán)間的密封；④靜環(huán)與靜環(huán)座間的密封；⑤密封端蓋與泵體間的密封。一般來(lái)說(shuō)，軸套外伸的軸間、密封端蓋與泵體間的泄漏比較容易發(fā)現(xiàn)和解決，但需細(xì)致觀察。其余的泄漏直觀上很難辨別和判斷，須在長(zhǎng)期管理、維修實(shí)踐的基礎(chǔ)上，對(duì)泄漏癥狀進(jìn)行觀察、分析、研判，才能得出正確結(jié)論。

安裝時(shí)，應(yīng)按產(chǎn)品的使用說(shuō)明書(shū)或樣本，保證機(jī)械密封的安裝尺寸。 </p> <p> <span style="font-size:12px;">裝入前，軸（軸套）、壓蓋應(yīng)無(wú)毛刺，軸承狀況良好；密封件、軸、密封腔、壓蓋都應(yīng)該清洗干凈。</span> </p> <p> 為減少摩擦阻力，軸上安裝機(jī)械密封的部位要薄薄地涂上一層油，以進(jìn)行潤(rùn)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(xiāo)的結(jié)構(gòu)，不宜涂油，應(yīng)干式裝入壓蓋。 </p> <p> <span style="font-size:12px;">先將靜環(huán)與壓蓋一起裝在軸上，注意不要與軸相碰，然后將動(dòng)環(huán)組件裝入。彈簧座或傳動(dòng)座的緊定螺釘應(yīng)分幾次均勻擰緊。</span> </p> <p>

機(jī)械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機(jī)械基礎(chǔ)元件之一，是各種泵類(lèi)設(shè)備的關(guān)鍵部件。對(duì)于機(jī)泵，超過(guò)50%機(jī)率的泄露問(wèn)題產(chǎn)生原因往往就在機(jī)械密封上！ </p> <p> 機(jī)械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機(jī)械密封，耐高壓、耐腐蝕機(jī)械密封，耐顆粒介質(zhì)機(jī)械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機(jī)械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機(jī)械密封。 </p> <p> 選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。 </p> <p> <p> 根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。 </p> <p> 根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動(dòng)壓式或非接觸型。 </p> <p> 根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤(rùn)滑、沖洗、保溫、冷卻等機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。 </p> <p> 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。 </p>

在液體介質(zhì)中工作的機(jī)械密封，一般均依靠液體介質(zhì)在動(dòng)、靜環(huán)摩擦面間所形成的液膜進(jìn)行潤(rùn)滑。因此，維持摩擦面間的液膜是機(jī)械密封穩(wěn)定運(yùn)轉(zhuǎn)、延長(zhǎng)使用壽命所必不可少的。 </p> <p> 強(qiáng)化潤(rùn)滑的結(jié)構(gòu) </p> <p> 靜壓潤(rùn)滑： </p> <p> 所謂靜壓潤(rùn)滑是將有壓力的潤(rùn)滑液體直接引入摩擦面以起到潤(rùn)滑的作用。用此有壓力的潤(rùn)滑液與機(jī)械內(nèi)的流體壓力相對(duì)抗，此種形式通常也稱(chēng)為流體靜壓力密封。引入的潤(rùn)滑液體由單獨(dú)的液源供給，如液壓泵等。只要條件允許，應(yīng)盡可能把氣體介質(zhì)條件轉(zhuǎn)換為液體介質(zhì)條件，這樣既便于潤(rùn)滑又便于密封。氣體介質(zhì)的機(jī)械密封應(yīng)采取措施建立氣膜潤(rùn)滑，如采用氣體靜壓受控膜機(jī)械密封或固體潤(rùn)滑，即選用自潤(rùn)滑材料作動(dòng)環(huán)或靜環(huán)。 </p> <p> 端面偏心： </p> <p> 一般機(jī)械密封，動(dòng)環(huán)的中心、靜環(huán)的中心和軸的中心線都在一條直線上，偏心尺寸不能過(guò)大，特別是對(duì)于高壓，偏心會(huì)使端面所受的壓力不均勻，而造成磨損不均勻。對(duì)于高轉(zhuǎn)速密封，不宜用動(dòng)環(huán)作為偏心環(huán)，否則由于離心力的平衡會(huì)使機(jī)器發(fā)生振動(dòng)。如果將動(dòng)環(huán)或靜環(huán)中的某一個(gè)環(huán)的端面中心做成與軸的中心線偏移部分距離，便能使環(huán)在旋轉(zhuǎn)時(shí)不斷帶入潤(rùn)滑液至滑動(dòng)面間起潤(rùn)滑作用。 </p> <p> <br /> </p> 與密封件相對(duì)滑動(dòng)零件的幾何位置精度(同心度)高材質(zhì)好(如鍍硬鉻)和表面粗糙度較細(xì)可延長(zhǎng)使用壽命。常州化工泵密封的用途和特點(diǎn)</p><p
