要將軸封部分的溫度設(shè)計(jì)為0℃，這時用作氣體密封，密封圈可用普通O形或V形密封圈。密封結(jié)構(gòu)是與泵體結(jié)構(gòu)相適應(yīng)，常用的低溫泵采用立式結(jié)構(gòu).3.輔助裝置(1)要盡可能加大沖洗量，加強(qiáng)冷卻措施，或提高密封腔內(nèi)壓力，來控制液溫升高所引起的氣化現(xiàn)象，要***避免從泵出口端裝沖洗管線來沖洗密封端面，因?yàn)樵诘蜏叵?，這種沖洗管線內(nèi)液體會氣化.所以，一般采逆流沖洗方式.(2)防止單端面密封在泵停轉(zhuǎn)過程中大氣中水分與密封接觸使邊緣結(jié)冰，可用甲醇等化冰劑加以溶解，阻封部分也可通人氮?dú)飧蓺饧右员Ｗo(hù).總之，既要充分冷卻又要采取保冷措施，山東脫硫泵用機(jī)械密封。(3)在高于密封面的部位裝設(shè)排氣管線，這樣，如果產(chǎn)生氣體也可從排氣管線逸出。有關(guān)低溫泵的輔助裝置見第七節(jié)低溫泵輔助系統(tǒng)。二、低溫甲烷泵機(jī)械密封低溫泵通常是立式結(jié)構(gòu)，密封腔設(shè)在泵的上部，山東脫硫泵用機(jī)械密封，密封結(jié)構(gòu)為雙端面平衡型機(jī)械密封。低溫泵的結(jié)構(gòu)及布置如圖10-19所示。1.低溫泵的結(jié)構(gòu)特點(diǎn)(1)筒形結(jié)構(gòu)，山東脫硫泵用機(jī)械密封，不必?fù)?dān)心低溫時發(fā)生變形.(2)一級葉輪位于底部，通過增減柱形筒體的長度(圖10-19中的葉輪只列出二級，實(shí)際有十多級)，.來適應(yīng)葉輪級數(shù)的變化。(3)液體從上向下進(jìn)人葉輪，由吸人端排氣從而起到有效的氣體分離器作用。(4)立式結(jié)構(gòu)排氣順暢。北京脫硫泵用機(jī)械密封型號。山東脫硫泵用機(jī)械密封</p><div

還與軸徑尺寸有關(guān).當(dāng)摩擦副環(huán)基體為不銹鋼、高鎳合金、欽合金時，熱鑲硬質(zhì)合金的允許使用溫度對不同軸徑的關(guān)系如圖10-9所示.5.摩擦副環(huán)與軸之間的許用間隙高溫條件下，由于摩擦副環(huán)與軸兩者的熱脹系數(shù)的差異，會出現(xiàn)摩擦副環(huán)與軸之間間隙趨近于零的現(xiàn)象，因而造成摩擦副環(huán)浮動性消失導(dǎo)致密封失效。所以在設(shè)計(jì)時必須合理和正確選擇摩擦副環(huán)與軸之間的間隙。二、高溫機(jī)械密封實(shí)例芳烴裝置循環(huán)油泵GA-102AB.功率1650kW，轉(zhuǎn)速6748r/min,輸送介質(zhì)為汽油，操作溫度262~284度，進(jìn)口壓力，出口壓力~175MPa，機(jī)械密封采用布格曼公司HSHF+MFL混合結(jié)構(gòu)，這是適合高溫、高壓和高速工作條件下的密封。這里HSHF是單端面、流體動壓式帶泵效螺旋結(jié)構(gòu)MFL是單端面金屬波紋管結(jié)構(gòu).HSHF和MFL都是彈簧靜止式，以適應(yīng)高速運(yùn)轉(zhuǎn)的要求.該密封從結(jié)構(gòu)上布置成串聯(lián)式，裝于油泵的吸人端和排出端，因HSHF帶有泵效螺旋，它與軸的旋轉(zhuǎn)方向有關(guān).在吸入端的泵效套(12A)是右螺旋，泵效外殼(25A)提左螺旋;在排出端的泵效套(12B)是左螺旋，泵效外殼(25B)是右螺旋，安裝時按圖上要求裝配不能搞錯.，圖10-10為HSHF2/103+MFL65/88的結(jié)構(gòu)圖.(圖3-22)Y4D型金屬波紋管密封是Eagle公司用于低壓(()。</p><p> 若不垂直，油封的密封唇會把潤滑油從軸上排干，也會導(dǎo)致密封唇的過度磨損。在運(yùn)轉(zhuǎn)中，殼體內(nèi)的潤滑劑微微滲出一點(diǎn)，以達(dá)到在密封面處形成。五、骨架油封的作用一般就是將傳動部件中需要潤滑的部件與出力部件隔離，不至于讓潤滑油滲漏，通常用于旋轉(zhuǎn)軸，是一種旋轉(zhuǎn)軸唇密封。骨架就如同混凝土構(gòu)件里面的鋼筋，起到加強(qiáng)的作用，并使油封能保持形狀及張力。按骨架型式可分為內(nèi)骨架油封，外骨架油封，內(nèi)外露骨架油封。骨架油封是采用質(zhì)量丁腈橡膠和鋼板制作而成，質(zhì)量穩(wěn)定，使用壽命長。1、防止泥沙、灰塵、水氣等自外侵入軸承中；2、限制軸承中的潤滑油漏出。對油封的要求是尺寸(內(nèi)徑、外徑和厚度)應(yīng)符合規(guī)定;要求有適當(dāng)?shù)膹椥裕軐⑤S適當(dāng)?shù)乜ㄗ?，起到密封作?要耐熱、耐磨、強(qiáng)度好、耐介質(zhì)(油或水等)，使用壽命長。六、油封的選擇油封的選擇要根據(jù)密封介質(zhì)和工作條件，密封介質(zhì)需要選擇油封的材料，工作條件主要考慮使用壓力、工作線速度、工作溫度范圍。選擇油封的材料時，必須考慮材料對工作介質(zhì)的相容性、對工作溫度范圍的適應(yīng)性和唇緣對旋轉(zhuǎn)軸高速旋轉(zhuǎn)時的跟隨能力。一般油封工作時其唇緣的溫度高于工作介質(zhì)溫度20~50℃，在選擇油封材料時應(yīng)予注意。延安格蘭富泵用機(jī)械密封選型。</p><div

三是安裝、拆卸困難，極易損壞靜環(huán)。誤區(qū)四：葉輪鎖母越緊越好？！機(jī)械密封泄漏中，軸套與軸之間的泄漏(軸間泄漏)是比較常見的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實(shí)導(dǎo)致軸間泄漏的因素較多，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導(dǎo)致軸間泄漏。鎖母鎖緊過度只會導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運(yùn)轉(zhuǎn)中鎖母會自動適時鎖緊，使軸間始終處于良好的密封狀態(tài)。誤區(qū)五：新的比舊的好？！相對而言，使用新機(jī)械密封的效果好于舊的，但新機(jī)械密封的質(zhì)量或材質(zhì)選擇不當(dāng)時，配合尺寸誤差較大會影響密封效果；在聚合性和滲透性介質(zhì)中，靜環(huán)如無過度磨損，還是不更換為好。因?yàn)殪o環(huán)在靜環(huán)座中長時間處于靜止?fàn)顟B(tài)，使聚合物和雜質(zhì)沉積為一體，起到了較好的密封作用。誤區(qū)六：拆修總比不拆好？！一旦出現(xiàn)機(jī)械密封泄漏便急于拆修，其實(shí)，有時密封并沒有損壞，只需調(diào)整工況或適當(dāng)調(diào)整密封就可消除泄漏。這樣既避免浪費(fèi)又可以驗(yàn)證自己的故障判斷能力，積累維修經(jīng)驗(yàn)提高檢修質(zhì)量。云南化工泵用機(jī)械密封泄露。山東脫硫泵用機(jī)械密封</p><p
