<p> 有壓雙封密封液系統(tǒng)的壓力一般要比一級(jí)密封前的壓力高0.01-0.03MPa。這樣一級(jí)密封泄漏時(shí)，密封液會(huì)進(jìn)入泵內(nèi)，確保了泵內(nèi)介質(zhì)不會(huì)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(cè)和報(bào)警。 </p> <p> 無(wú)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(jí)密封前的密封腔壓力。當(dāng)一級(jí)密封泄漏時(shí)，泵內(nèi)介質(zhì)會(huì)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(guò)壓力開關(guān)或液位開關(guān)實(shí)現(xiàn)泄露監(jiān)測(cè)和報(bào)警。通過(guò)密封液系統(tǒng)來(lái)監(jiān)測(cè)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。 </p> <p> <br /> 蘇州葉輪泵密封制造廠家設(shè)計(jì)輔助沖洗系統(tǒng)，沖洗壓力要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力因素來(lái)計(jì)算。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

在凝結(jié)過(guò)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>

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> 人們?cè)诜治鰴C(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。蘇州葉輪泵密封制造廠家</p><p

style="font-size:12px;"> 口環(huán)，也叫耐磨環(huán)。其主要作用是防止出口端介質(zhì)倒流回進(jìn)口端介質(zhì)也就是密封作用（因此有“密封環(huán)”這一名稱）；同時(shí)也起耐磨作用，避免葉輪和泵殼直接接觸損壞，有保護(hù)葉輪的作用（因此有“耐磨環(huán)”這一名稱）。</span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)，一般水泵的級(jí)數(shù)與口環(huán)的數(shù)量是一樣的，也就是說(shuō)一個(gè)5級(jí)的水泵，那么口環(huán)也就有5個(gè)，一個(gè)首口環(huán)，4個(gè)口環(huán)。</span> </p> <p> <span style="font-size:12px;">多級(jí)離心泵口環(huán)的作用是在葉輪與泵殼間形成狹窄、曲折的通道，來(lái)增加介質(zhì)的流動(dòng)阻力，達(dá)到減少介質(zhì)泄漏的目的。離心泵口環(huán)的設(shè)置還起到保護(hù)泵上主要零件不受磨損的作用(公眾號(hào):泵管家)，在口環(huán)磨損后，可以修復(fù)或更換新環(huán)、恢復(fù)正常裝配間隙，這樣既經(jīng)濟(jì)又便于檢修。</span> </p> <p> <span style="font-size:12px;">口環(huán)間隙大會(huì)將低泵的使用效率，經(jīng)過(guò)泵加壓的流體會(huì)過(guò)多的從泵出口區(qū)域沿葉輪與口環(huán)的間隙返回到進(jìn)口，從而降低了泵的使用效率，同時(shí)由于流量的加大，會(huì)使口環(huán)過(guò)早的被磨損。口環(huán)間隙過(guò)大，會(huì)導(dǎo)致泵的流量降低，嚴(yán)重時(shí)不上量。 </span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)的完好性及它與葉輪問(wèn)徑向間隙含，在拆卸泵時(shí)應(yīng)首先檢查。如離心泵口環(huán)已有溝槽等缺損或已破裂或間隙艿超過(guò)表5中所規(guī)定的數(shù)值時(shí)，應(yīng)更換新口環(huán)或?qū)⒃诃h(huán)補(bǔ)焊修復(fù)。</span> </p> <p>
