造成泄漏的原因主要有兩個(gè)方面：一是密封面上有間隙。二是密封部位兩側(cè)存在壓力差，消除或減小任何一個(gè)因素都可以阻止或減小泄漏，達(dá)到密封的目的。泵的設(shè)計(jì)壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內(nèi)部的間隙。 </p> <p> <br /> </p><p> <p>

在凝結(jié)過程中，由于體積急劇縮小，四周的液體以極大的速度沖向整個(gè)凝結(jié)空間，使泵內(nèi)造成沖擊振動(dòng)和噪音。在壓力很大、頻率很高的液體質(zhì)點(diǎn)連續(xù)沖擊下，金屬表面逐漸因疲勞而破壞，這種破壞稱為剝蝕。 </p> <p> 同時(shí)溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機(jī)械剝蝕的共同作用，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進(jìn)口氣蝕的措施有以下幾點(diǎn)： </p> <p>

泵用機(jī)械密封種類繁多，型號各異，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。一般來說，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，須在長期管理、維修實(shí)踐的基礎(chǔ)上，對泄漏癥狀進(jìn)行觀察、分析、研判，才能得出正確結(jié)論。

style="text-indent:25px">影響密封的主要因素有哪些？密封本身質(zhì)量、工藝操作條件、裝配安裝精度、主機(jī)本身精度、密封輔助系統(tǒng)。南京多級泵密封購買價(jià)格</p><p> 有害介質(zhì)時(shí)為了取得更好的密封效果，采用雙重密封，根據(jù)密封液系統(tǒng)壓力可分為有壓雙封(雙端面機(jī)械密封)和無壓雙封(串聯(lián)式機(jī)械密封)。 </p> <p> 有壓雙封密封液系統(tǒng)的壓力一般要比一級密封前的壓力高0.01-0.03MPa。這樣一級密封泄漏時(shí)，密封液會進(jìn)入泵內(nèi)，確保了泵內(nèi)介質(zhì)不會泄漏到外界。由于密封液進(jìn)入泵內(nèi)，密封液系統(tǒng)壓力、液位降低，可以實(shí)現(xiàn)密封的泄漏監(jiān)測和報(bào)警。 </p> <p> 無壓雙封密封系統(tǒng)內(nèi)的壓力一般為常壓或微壓，低于一級密封前的密封腔壓力。當(dāng)一級密封泄漏時(shí)，泵內(nèi)介質(zhì)會進(jìn)人密封液系統(tǒng)，導(dǎo)致密封液系統(tǒng)的壓力和液位升高，可以通過壓力開關(guān)或液位開關(guān)實(shí)現(xiàn)泄露監(jiān)測和報(bào)警。通過密封液系統(tǒng)來監(jiān)測雙端面機(jī)械密封失效與否，也是其區(qū)別于單端面機(jī)械密封**主要的形式之一。
