氣體不會(huì)在泵的中部滯留·(5)無軸的彎曲問題，軸封可遠(yuǎn)離泵體，減少熱的影響。電機(jī)安裝架為遮風(fēng)結(jié)構(gòu)，所以電機(jī)的溫升對(duì)泵幾乎沒有影響。(6)泵殼埋于地下，易于保冷.所以，石油液化氣用的低溫泵常用以上這種結(jié)構(gòu).2.低溫甲烷泵機(jī)械密封甲烷液化氣在-99℃時(shí)的蒸汽壓接近3MPa.乙烯裝置脫甲烷塔底泵在-53℃時(shí)出口壓力近似3MPa，采用雙端面串聯(lián)式機(jī)械密封，它是比拉公司BB81-K7+BB81B-S7型，尺寸為45x39與50x45(圖10-20)。耐腐蝕機(jī)械密封在腐蝕性介質(zhì)中，機(jī)械密封的零件受到介質(zhì)的強(qiáng)烈侵蝕，摩擦面同時(shí)受到.腐蝕和磨損，這種現(xiàn)象稱為“磨蝕“，其腐蝕速度約為無摩擦?xí)r的10~50倍.某些結(jié)構(gòu)材料具有優(yōu)良的耐蝕性能，耐磨性能卻較差;而另一些結(jié)構(gòu)材料雖具有良好的耐磨性，耐蝕性卻很差.因此，摩擦副應(yīng)選擇既要耐腐蝕又要耐磨，輔助密封圈、彈擠和結(jié)構(gòu)件也要有良好的耐蝕性能.在設(shè)計(jì)耐腐蝕機(jī)械密封時(shí)，一般采取以下一些措施:1.結(jié)構(gòu)上的隔離措施采用外裝式結(jié)構(gòu)，經(jīng)過適當(dāng)?shù)倪x擇，外裝式密封可以做到無金屬件與工藝介質(zhì)接觸，小的零件如彈簧、銷子可不受工藝介質(zhì)腐蝕.外裝式有普通型機(jī)械密封和波紋管型機(jī)械密封兩種，’以波紋管型密封結(jié)構(gòu)較好(圖10-21).如密封件材質(zhì)耐蝕能力許可。赤峰高溫泵用機(jī)械密封圖木舒克福斯泵用機(jī)械密封選型。</p><div

三、區(qū)分骨架油封型號(hào)C型骨架油封為內(nèi)骨架油封可分為SC型、TC型、VC型、KC型、DC型這五種，分別是單唇內(nèi)骨架油封、雙唇內(nèi)骨架油封、單唇無簧內(nèi)骨架油封、雙唇無簧內(nèi)骨架油封、雙唇雙簧內(nèi)骨架油封。G型骨架油封是外出有螺紋狀，其類型和C型一樣，只是在工藝上在外側(cè)修改成有螺紋狀，類似于O型圈的作用，即起到加強(qiáng)密封效果的作用，還能起到固定油封不松動(dòng)。B型骨架油封是骨架內(nèi)側(cè)有膠料或者骨架內(nèi)外都沒有膠料，沒有膠料會(huì)讓散熱性能更好。A型骨架油封是裝配式油封，結(jié)構(gòu)相對(duì)上述三種相對(duì)復(fù)雜，特點(diǎn)是承壓性能更好更優(yōu)異。四、骨架油封的密封原理及應(yīng)用?骨架油封共分三部分：自緊彈簧、密封主體、加強(qiáng)骨架。?骨架油封的密封原理：由于在油封與軸之間存在著油封刃口控制的油膜，此油膜具有流體潤(rùn)滑特性。?密封原理解析：骨架油封的作用下，油膜的剛度恰好使油膜與空氣接觸端形成一個(gè)新月面，防止了工作介質(zhì)的泄漏，從而實(shí)現(xiàn)旋轉(zhuǎn)軸的密封。油封的密封能力，取決于密封面油膜的厚度，厚度過大，油封泄漏；厚度過小，可能發(fā)生干摩擦，引起油封和軸磨損；密封唇與軸之間沒有油膜，則易引起發(fā)熱、磨損。因此，在安裝時(shí)，必須在密封圈上涂些油，同時(shí)保證骨架油封與軸心線垂直。</p><p> 泵吸入口處和葉片背面等處聚集氣體會(huì)導(dǎo)致流阻阻力增大甚至斷流，繼而使工況惡化，必需汽蝕量增加，氣體密度小，比容大，可壓縮性大，流變性強(qiáng)，離心力小，轉(zhuǎn)換能量性能差是引起泵工況惡化的主要原因。試驗(yàn)表明，當(dāng)液體中的氣量（體積比）達(dá)到3%左右時(shí)，泵的性能將出現(xiàn)陡降，當(dāng)入口氣體達(dá)20%～30%時(shí)，泵完全斷流。離心泵允許含氣量（體積比）極限小于5%。葉輪形式因?yàn)槭沂瘽{液中含有氯離子(20000～60000)X10-6，pH值～7之間，濃度20%～35%之間，高達(dá)60%。脫硫泵的過流部件，必須選擇具有抗磨損和抗腐蝕的材料，(公眾號(hào):泵管家)有襯膠、襯陶瓷、全金屬合金等材質(zhì)。脫硫泵一般采用懸臂式單級(jí)單吸離心泵，比轉(zhuǎn)速一般在250～350。葉輪可按照一般離心泵的方法設(shè)計(jì)，分閉式葉輪、開式葉輪等?？紤]到電廠需要比較長(zhǎng)的連續(xù)運(yùn)行時(shí)間，故對(duì)泵的汽蝕和效率都有一定的要求。一般帶背葉片，降低密封腔壓力，降低磨損。由于介質(zhì)有強(qiáng)腐蝕性,葉輪的防腐措施：1.使用高分子材料包覆葉輪，可以保護(hù)葉輪不受腐蝕2.使用特種金屬制成3.使用高分子材料制作葉輪。目前國際上常用的是高分子材料包覆葉輪，具有非常好的耐磨耐腐蝕性。采用可調(diào)軸承座使軸向位置可調(diào)節(jié)。吉林襄樊五二五泵用機(jī)械密封型號(hào)。</p><div

因?yàn)檫^流部件的使用壽命（耐磨耐腐蝕件）的壽命取決于多種不同因素，工況的的多樣性和復(fù)雜性導(dǎo)致同樣品質(zhì)的材質(zhì)的使用壽命是有差異的。但是在前期選型階段可以讓有實(shí)力的生產(chǎn)廠家為其做合理工況選型設(shè)計(jì)。其次，在電力行業(yè)，主要是火力發(fā)電廠。目前我國電廠中主要是火力發(fā)電和水利發(fā)電，在火電廠中，由于用大量燃煤發(fā)電，燃煤后的爐渣或者灰渣需要***，渣漿泵被用在除灰渣的作用，爐渣通過混合一定量的水后，通過渣漿泵將其輸送到灰渣堆放的地方，因此有時(shí)渣漿泵在電廠也成為灰渣泵。再次，在洗煤行業(yè)，由于工況不同，較大煤塊，煤矸石容易堵塞，對(duì)于渣漿泵的設(shè)計(jì)要求很高?；幢钡V務(wù)局下屬某洗煤廠05年采用經(jīng)特殊設(shè)計(jì)的、替代原來從澳大利亞進(jìn)口的渣漿泵，至今運(yùn)轉(zhuǎn)正常，輸送較大煤塊、煤矸石無堵塞，使用磨損壽命超過了國外進(jìn)口泵。在海水選砂領(lǐng)域，渣漿泵應(yīng)用也開始逐漸被客戶認(rèn)可。但是在海水里選砂，河道里挖沙，渣漿泵更容易被稱為砂泵，挖泥泵。盡管叫法不一，但是從結(jié)構(gòu)特點(diǎn)和泵的性能原理上來講，都可以通稱為渣漿泵。因此在這海水選砂中我們經(jīng)常稱為砂泵，在河道清淤里面習(xí)慣上叫挖泥泵。渣漿泵的用途雖然廣，但是正確的應(yīng)用是十分重要的。赤峰高溫泵用機(jī)械密封</p><p
