泵用機械密封是精密的部件，制造精度及安裝精度要求都很嚴格，如果裝配不當(dāng)就會影響密封性能，要正確安裝必須注意以下幾點： </p> <p> 泵用機械密封的冷卻和沖洗 </p> <p> 第一種冷卻形式由水泵的出口或高壓端，將輸送的干凈介質(zhì)，直接沖洗密封端面，然后進入泵腔內(nèi)，通過介質(zhì)的不斷循環(huán)，將磨擦端面的的磨擦熱帶走達到冷卻的效果。 </p> <p> 第二種冷卻方式在第一種冷卻形式的基礎(chǔ)上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來的液體。當(dāng)密封介質(zhì)溫度＞150℃時除了在冷卻水套中通過冷卻水及靜環(huán)背部冷卻外，應(yīng)采取強制冷卻措施。即從泵出口的干凈介質(zhì)應(yīng)預(yù)先經(jīng)熱交換器冷卻至50℃時。再進入密封腔冷卻沖洗，該形式是冷卻效果**良好的一種。 </p> <p> 如介質(zhì)中含有顆粒或雜質(zhì)，必須采用過濾措施，把常溫干凈沖洗液輸入密封腔內(nèi)。操作中，因抽空、氣蝕，蘇州電動泵密封可定制企業(yè)、憋壓等異常現(xiàn)象，蘇州電動泵密封可定制企業(yè)，引起較大的軸向力，蘇州電動泵密封可定制企業(yè)，使動、靜環(huán)接觸面分離。蘇州電動泵密封可定制企業(yè)</p><div

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）；同時也起耐磨作用，避免葉輪和泵殼直接接觸損壞，有保護葉輪的作用（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)，一般水泵的級數(shù)與口環(huán)的數(shù)量是一樣的，也就是說一個5級的水泵，那么口環(huán)也就有5個，一個首口環(huán)，4個口環(huán)。</span> </p> <p> <span style="font-size:12px;">多級離心泵口環(huán)的作用是在葉輪與泵殼間形成狹窄、曲折的通道，來增加介質(zhì)的流動阻力，達到減少介質(zhì)泄漏的目的。離心泵口環(huán)的設(shè)置還起到保護泵上主要零件不受磨損的作用(公眾號: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)濟又便于檢修。</span> </p> <p> <span style="font-size:12px;">口環(huán)間隙大會將低泵的使用效率，經(jīng)過泵加壓的流體會過多的從泵出口區(qū)域沿葉輪與口環(huán)的間隙返回到進口，從而降低了泵的使用效率，同時由于流量的加大，會使口環(huán)過早的被磨損。口環(huán)間隙過大，會導(dǎo)致泵的流量降低，嚴重時不上量。 </span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)的完好性及它與葉輪問徑向間隙含，在拆卸泵時應(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表5中所規(guī)定的數(shù)值時，應(yīng)更換新口環(huán)或?qū)⒃诃h(huán)補焊修復(fù)。</span> </p> <p> <br /> </p> <p>

style="font-size:12px;">軸的表面線速度：在同一直徑條件下，不同材料制造的油封，適應(yīng)軸面旋轉(zhuǎn)線速度的能力不同，其關(guān)系如下圖所示。油封使用的線速度范圍一般小于15m/s, 滿意的潤滑和良好的散熱條件才是決定性因素。相應(yīng)較低的數(shù)據(jù)，適用于更為苛刻的條件。 </span> </p> <p> <span style="font-size:12px;">溫度：由于旋轉(zhuǎn)軸表面與油封的密封唇部產(chǎn)生摩擦，所以密封唇口部的溫度高于油液中的溫度，一般油封工作時其唇緣的溫度高于工作介質(zhì)溫度20~50℃。隨著轉(zhuǎn)速增高，壓力增加密封唇口處的溫度也隨之上升。另外，帶有防塵唇的油封，比無防塵唇的油封會出現(xiàn)高于20℃的過高溫度。當(dāng)超過容許溫度時會縮短油封的工作壽命，造成密封唇過早長久性硬化，以及磨損加大。油封的工作溫度范圍與油封使用的材料有關(guān)：材料為丁晴橡膠（NBR）時為-40~120℃，亞力克橡膠（ACM）-30~180℃，氟橡膠（FPM）-25~300℃。</span> </p> <p> <span style="font-size:12px;">壓力：油封主要用于無壓或者在微壓的條件下使用，比較大工作壓力0.02～0.05Mpa。當(dāng)工作壓力超過這個值時應(yīng)選用耐壓型油封。</span> </p> <p> <br /> </p><p> 化工泵油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補償能力，但不耐高壓，所以一般用在低壓場合的化工泵上。 </p> <p> 化工泵依靠離心原理來抽取液體物料，特殊材料制成的化工泵適用于瓶、桶、缸、池或其他容器中抽取腐蝕性液體。由于化工泵所抽取的介質(zhì)有腐蝕、揮發(fā)、等危險性的存在，對泵體的密封性能要求，要比其他種類的泵高很多。 </p> <p> 化工泵油封應(yīng)安裝在制造精度為h8～h9，表面粗糙度為1.6～0.8μm且經(jīng)過表面硬化處理的軸上。密封介質(zhì)不應(yīng)含有固體微粒和雜質(zhì)，否則會造成油封和軸的迅速磨損而使密封失效。 </p> <p> 在選擇此種密封方法是，要充分考慮化工泵所輸送到物料的性能和要求，以避免不必要的泄漏，防止意外的發(fā)生。 </p> <p> 造成油封漏油的主要因素： </p> <p> 油封密封不嚴是造成漏油的主要因素。當(dāng)軸出現(xiàn)磨損形成溝槽，即使更換新油封仍不能密封時，是由于油封唇口與軸的接觸壓力下降，造成安裝后油封唇直徑與軸徑的過盈量太小。 </p> <p> 現(xiàn)以S195型柴油機曲軸油封為例，分析其密封不嚴的主要原因是：油封制造質(zhì)量差軸或軸承質(zhì)量差使用維護不當(dāng)安裝不當(dāng)保管不當(dāng)，受環(huán)境污染造成不良影響 </p> <p> <br /> 機械密封的密封面要有一定的比壓，從而達到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。</p><div

100多年來，人們采用填料一類的多種密封材料，使液體從液泵殼體沿著主軸的向外泄漏量不斷減少。盡管現(xiàn)代工藝流程中采用的液泵，仍然較大程度地沿用**古老的密封設(shè)計——填料盒，因為其起步費用低，而且又為工廠的工作人員所熟悉。 </p> <p> 然而，由于環(huán)境問題的關(guān)系，采用填料密封的方法已逐漸不能被人們所接受，特別是針對現(xiàn)代工藝流程中比較普遍的、腐蝕性較強的液體而言。因此，在實際應(yīng)用中，以機械密封代替填料密封的情況越來越多。 </p> <p> <br /> 密封件的存放室溫比較好在30℃以下，避免密封件產(chǎn)生高溫老化。蘇州化工泵用密封供應(yīng)商</p><p
