**通常的做法是將密封安裝在填料盒的內(nèi)部。但這種做法要求在密封維修時將液泵的濕端拆卸下來，其主要好處是密封的環(huán)境衛(wèi)生易于控制。 </p> <p> <span style="font-size:12px;"> 外密封的安裝方式是將靜態(tài)密封面的方向顛倒過來，主軸上的旋轉(zhuǎn)單元位于填料盒壓蓋的外面，江蘇單級泵密封市場批發(fā)價格。外密封主要具有以下五大好處：</span> </p> <p> 安裝容易; </p> <p> 費(fèi)用相對較低; </p> <p> 可以連續(xù)監(jiān)控和清潔; </p> <p> 適于無法在內(nèi)部安裝密封的很小填料盒; </p> <p> 由于其位置接近軸承，對主軸偏差的困難影響較少，江蘇單級泵密封市場批發(fā)價格。 </p> <p> <span style="font-size:12px;"> 其主要缺點(diǎn)是離心力會將固體顆粒從密封的下面甩向密封的接觸面上。因此，這類密封主要適用于清潔且不含有磨料的液體。</span> </p> <p> <span style="font-size:12px;"> 近年來，江蘇單級泵密封市場批發(fā)價格，分離式密封已成為外密封中的另一重要附加特性。分離式密封是一個成套總成，安裝于填料盒與軸承套之間，采用這種設(shè)計(jì)，在密封需要更換時，不需要每次都拆卸液泵。這類密封結(jié)合探討其他設(shè)計(jì)標(biāo)準(zhǔn)正在逐步開發(fā)之中。由于這種設(shè)計(jì)易于更換密封，因此應(yīng)抵擋**只更換密封件的這種誘惑，而對出現(xiàn)故障的根源不做進(jìn)一步的調(diào)查，這一點(diǎn)非常重要。</span>

高溫?zé)嵊捅弥饕谐５妆?、減底泵、催化油漿泵，該類泵的特點(diǎn)是溫度高（370℃-400℃）、油品粘度大、塔底有雜質(zhì)。我們針對高溫泵的這些特點(diǎn)采用的是YH-609系列機(jī)械密封, 結(jié)構(gòu)選型主要結(jié)合了以下幾個方面: </p> <p> 金屬波紋管旋轉(zhuǎn)結(jié)構(gòu) </p> <p> 旋轉(zhuǎn)波紋管密封在旋轉(zhuǎn)離心力作用下可以自身清洗波紋管，減少波紋管**沉積和內(nèi)側(cè)結(jié)焦，并能防止因急冷造成的波紋管變形。泵類設(shè)備轉(zhuǎn)速一般為2950r/min，機(jī)械密封線速度遠(yuǎn)小于25m/s,因此，可以選用旋轉(zhuǎn)結(jié)構(gòu)。 </p> <p> 密封結(jié)構(gòu)形式采用開槽斜面擠緊軸套 </p> <p> 這種定位傳動可靠，安裝拆卸方便且不傷軸。并設(shè)置有限位板，便于泵外調(diào)整密封的壓縮量。波紋管內(nèi)徑一處設(shè)一45℃斜角，以分散應(yīng)力，延長波紋管壽命。輔助密封采用柔性石墨替代合成橡膠，可以承受高達(dá)425℃的高溫。 </p> <p> 摩擦副材料的選取 </p> <p> 對摩擦副材料的選取我們采用“硬對硬”結(jié)構(gòu)，起初動靜環(huán)我們選擇了SiC-WC，但是運(yùn)轉(zhuǎn)一段時間發(fā)現(xiàn)動環(huán)出現(xiàn)肯邊現(xiàn)象。改用YG6-YG6之后，設(shè)備運(yùn)轉(zhuǎn)一直正常。 </p> <p> <br /> 淮安化工泵用密封廠家泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時高速旋轉(zhuǎn)產(chǎn)生的離心力，會阻擋介質(zhì)的泄漏。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

</p> <p> 泵用機(jī)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(jìn)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(dá)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(qiáng)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(jìn)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)。 </p><p> 機(jī)械密封裝配前的檢查有哪些內(nèi)容？答：一般性檢查：主要檢查個零件的型號、規(guī)格、性能、配合尺寸及有無缺口、點(diǎn)坑、變形和裂紋等損傷。動、靜環(huán)的檢查：密封端面要光潔明亮、物崩邊、點(diǎn)坑、溝槽、劃痕等缺點(diǎn)。對石墨環(huán)，還要浸沒有檢查是否有裂紋。 </p> <p> .機(jī)械密封彈簧的檢查都包括哪些內(nèi)容？答：彈簧的檢查包括：總?cè)?shù)、有效圈數(shù)、自由高度、軸心對端面是否垂直、彈簧旋向。但彈簧必須檢查旋向，多彈簧不需要檢查旋向。新彈簧要檢查其原始自由高度，自由高度要測量，并與原始記錄比較，殘余變形過大的要更換掉。舊彈簧清洗干凈后，要測量其彈力，彈力減少20%的要更換掉。多彈簧機(jī)械密封，各彈簧自由高度差不得小于0.5mm。如果密封無法直接裝入到預(yù)定的位置，就需要對相關(guān)尺寸進(jìn)行調(diào)整，避免硬裝現(xiàn)象的發(fā)生。</p><div

螺紋密封在泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟(jì)密封，二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外。密封面的粗糙度以及與螺紋孔的相對幾何位置精度對密封效果影響也很大。于由密封墊片在擰緊螺紋時不*承受壓緊力，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當(dāng)墊片為非金屬時，一般只適用于壓力不高的場合，如果墊片為金屬則適用壓力可達(dá)30Mpa以上。 </p> <p> 泵上經(jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟(jì)性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無論采用"錐對錐"還是"柱對錐"，密封效果相同，只是使用地域不同而已。我國目前兩種形式同等采用。影響密封效果的常見原因是在加工螺紋底孔時尺寸偏大，使螺紋牙形變短，牙頂變寬，造成密封面減小，當(dāng)密封壓力升高后產(chǎn)生泄漏，甚至將絲堵壓出。泄漏通道也可同時存在，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。江蘇單級泵密封市場批發(fā)價格</p><p

選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。 </p> <p> 選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補(bǔ)償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。 </p> <p> <br />
