在石油化工行業(yè)，離心泵具有性能范圍廣、流量均勻、結(jié)構(gòu)簡單、運(yùn)轉(zhuǎn)可靠和維修方便等諸多優(yōu)點(diǎn)，得到了廣的使用，占裝置泵總量的70～80％。而常見離心泵有單端面密封離心泵、雙端面密封離心泵及屏蔽泵等。那么，在輸送危險(xiǎn)物料時(shí)單端面密封離心泵、雙端面密封離心泵及屏蔽泵那個(gè)安全性更好，相對(duì)那種泵又比較經(jīng)濟(jì)。本文以甲醇裂解制氫裝置甲醇輸送泵為例，針對(duì)這3種類型的離心泵的結(jié)構(gòu)特點(diǎn)和軸封特性進(jìn)行分析和探討。一、案例某石化企業(yè)甲醇裂解制氫裝置，原料由甲醇輸送泵P-3307A/B送到裝置進(jìn)料泵,該甲醇輸送泵工藝技術(shù)參數(shù)如下：表1-1：甲醇輸送泵工藝技術(shù)參數(shù)序號(hào)設(shè)備名稱設(shè)備位號(hào)輸送介質(zhì)流量m3/h揚(yáng)程m溫度℃1甲醇輸送泵P-3307A/B甲醇3010040甲醇的特性：甲醇是一種有機(jī)化合物，密度g/mL，沸點(diǎn)℃。甲醇揮發(fā)度高、無色、易燃易爆、有毒，誤飲5～10毫升能雙目失明，大量飲用會(huì)導(dǎo)致死亡。常用危險(xiǎn)化學(xué)品的分類及標(biāo)志(GB13690-92)將該物質(zhì)劃為第類中閃點(diǎn)易燃液體。二、各泵的結(jié)構(gòu)特點(diǎn)和軸封特性1、機(jī)械密封概述機(jī)械密封（也稱端面密封）是一種用來解決旋轉(zhuǎn)軸和機(jī)體之間的密封裝置，它是由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面，在流體壓力和補(bǔ)償機(jī)構(gòu)彈力的作用及輔助密封的配合下。德州增壓泵用機(jī)械密封貴州襄樊五二五泵用機(jī)械密封泄露。</p><div

據(jù)我國石油化工行業(yè)統(tǒng)計(jì)，80%以上的離心泵采用的密封方式為機(jī)械密封。由于工況條件的不同，離心泵在輸送物料過程中，經(jīng)常出現(xiàn)機(jī)械密封處物料的泄漏，給環(huán)境造成污染，并造成能源的浪費(fèi)。機(jī)械密封是離心泵的主要易損件之一，因而泵的故障多數(shù)是由密封失效所導(dǎo)致的。據(jù)統(tǒng)計(jì)，機(jī)械密封失效導(dǎo)致泵的故障占設(shè)備故障率的50%以上，所以有必要對(duì)離心泵的機(jī)械密封泄漏進(jìn)行分析改進(jìn)，以降低泵的故障率。一、離心泵工作原理及機(jī)械密封裝置的作用離心泵通過電機(jī)、聯(lián)軸器，使其葉輪高速旋轉(zhuǎn)，在葉片之間的液體受到葉片的推動(dòng)，在離心力的作用下，不斷地從中心被甩向四周，當(dāng)泵內(nèi)液體從葉輪中心被拋向邊緣時(shí)，中心處形成了低壓區(qū)，由于進(jìn)泵前的液體壓強(qiáng)大于泵吸入口處的壓強(qiáng)，在壓強(qiáng)差的作用下，液體便經(jīng)吸入管連續(xù)地吸入泵內(nèi)，以補(bǔ)充被排出液體的位置，只要葉輪不停地旋轉(zhuǎn)，液體便不斷地吸入和排出。泵軸穿過泵殼時(shí)，動(dòng)靜之間有間隙存在時(shí)，泵內(nèi)的液體就會(huì)從間隙漏至泵外，若吸入端是真空，則外界空氣會(huì)漏入泵內(nèi)，嚴(yán)重影響泵的工作，為了減少泄漏，一般在動(dòng)靜間隙處裝有軸端密封裝置。軸封裝置是離心泵的重要部件，它直接關(guān)系到離心泵能否正常工作。現(xiàn)在軸封裝置一般采用機(jī)械密封。</p><p> 特種機(jī)械密封是指介質(zhì)、壓力、速度、溫度、結(jié)構(gòu)和用途方面與普通機(jī)械密封有所區(qū)別的機(jī)械密封，國內(nèi)也稱高參數(shù)機(jī)械密封.將機(jī)械密封分為普通和特種兩類，是便于說明機(jī)械密封的結(jié)構(gòu)、工作條件和使用要求，因此，有的密封廠商除列舉正常密封產(chǎn)品外，也列出高載荷機(jī)械密封;有的廠商則將產(chǎn)品樣本以外的機(jī)械密封稱作特種機(jī)械密封;有的廠商將高溫、高壓、高速的機(jī)械密封分別列出或加上標(biāo)志，以便與普通機(jī)械密封產(chǎn)品相區(qū)別;有的廠商則以使用溫度來區(qū)分普通機(jī)械密封與特種機(jī)械密封.例如，英國克蘭公司將溫度一20~+230℃作為正常產(chǎn)品，超出以上溫度范圍的機(jī)械密封，就作為特種機(jī)械密封產(chǎn)品來考慮.本章所列的特種機(jī)械密封*指釜用、高溫、高壓、高速、低溫、真空和強(qiáng)腐蝕介質(zhì)以及帶磨料介質(zhì)的機(jī)械密封釜用機(jī)械密封釜用機(jī)械密封是指攪拌器(混合器)密封.從引進(jìn)裝置中使用攪拌器的情況來看，凡大型釜用攪拌器都采用機(jī)械密封，它占攪拌器總量的，而未采用機(jī)械密封的攪拌器多數(shù)為小功率和堆、槽內(nèi)的小型攪拌器.近年來，機(jī)械密封在攪拌器上得到應(yīng)用，一是因?yàn)閿嚢杵鬏S的擺動(dòng)量大，有的攪拌軸長達(dá)7~8m，雖然有底部支承裝置，但擺動(dòng)量仍然很大，填料密封已滿足不了要求;二是使用條件越來越苛刻。攀枝花福斯泵用機(jī)械密封泄露。</p><div
