據(jù)我國石油化工行業(yè)統(tǒng)計，80%以上的離心泵采用的密封方式為機械密封。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。機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，機械密封失效導(dǎo)致泵的故障占設(shè)備故障率的50%以上，所以有必要對離心泵的機械密封泄漏進行分析改進，以降低泵的故障率。一、離心泵工作原理及機械密封裝置的作用離心泵通過電機、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，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，中心處形成了低壓區(qū)，由于進泵前的液體壓強大于泵吸入口處的壓強，在壓強差的作用下，液體便經(jīng)吸入管連續(xù)地吸入泵內(nèi)，以補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，動靜之間有間隙存在時，泵內(nèi)的液體就會從間隙漏至泵外，若吸入端是真空，則外界空氣會漏入泵內(nèi)，嚴重影響泵的工作，為了減少泄漏，一般在動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?，F(xiàn)在軸封裝置一般采用機械密封。自貢襄樊五二五泵用機械密封廠家延安格蘭富泵用機械密封泄露。</p><div

保持貼合并相對滑動而構(gòu)成防止流體泄漏的裝置，常用于機泵、壓縮機等旋轉(zhuǎn)式流體機械。機械密封的基本元件由動環(huán)、靜環(huán)、壓蓋、推環(huán)、彈簧、定位環(huán)、軸套、輔助密封（動靜環(huán)密封圈、軸套密封圈）組成。其機械密封外形結(jié)構(gòu)圖如圖2-1機械密封外形結(jié)構(gòu)圖機械密封的工作原理。它是靠彈性構(gòu)件（如彈簧或波紋管，或波紋管及彈簧組合構(gòu)件）和密封介質(zhì)的壓力在旋轉(zhuǎn)的動環(huán)和靜環(huán)的接觸表面（端面）上產(chǎn)生適當(dāng)?shù)膲壕o力，使這兩個端面緊密貼合，端面間維持一層極薄的液體膜而達到密封的目的。這層液體膜具有流體動壓力與靜壓力，起著潤滑和平衡壓力的作用。機械密封一般有四個密封部位（通道），A、B、C、D。A通道是旋轉(zhuǎn)環(huán)與靜止環(huán)的端面彼此貼合作相對滑動的動密封，它是機械密封裝置中的主密封，也是決定機械密封性能和壽命的關(guān)鍵。B處為靜環(huán)7與壓蓋4端面之間的密封；C處為動環(huán)3與軸（或軸套）9配合面之間的密封，因能隨補償環(huán)軸向移動并起密封作用，所以又稱副密封；D處為壓蓋與泵殼端面之間的密封。B、D、C三處是靜止密封，一般不易泄漏。2、單端面密封離心泵的結(jié)構(gòu)和軸封特性單端面密封離心泵的軸封由一對摩擦副密封端面組成，只有一級密封，一般有自沖悉系統(tǒng)。</p><p>

其缺點是有的波紋管彈力較小，需加輔助彈簧，如（圖8a）所示。集裝式機械密封是將普通的機械密封、軸套和密封壓蓋預(yù)先組合成一個整體，將其安裝到泵上后，不做任何調(diào)整（包括彈簧的壓縮量），只固定軸套和壓蓋，再把剖分式卡環(huán)取下（圖12中的A）即可投入使用。由此可見，卡環(huán)的（軸向）寬度等于彈簧的壓縮量，并且，從外部就可以知道該值的大小和變化情況。事先組裝，容易保證密封的安裝質(zhì)量，可減少因安裝不良引起的失效。近年來集裝式密封發(fā)展很快，因卡環(huán)的結(jié)構(gòu)、軸套與軸的傳動以及軸與軸套之間的密封等方面的不同，出現(xiàn)了許多種集裝式密封。三、國產(chǎn)104型機械密封國產(chǎn)104型機械密封為內(nèi)裝、內(nèi)流、單端面、單彈簧、非平衡型密封，輔助密封圈有V形和O形兩種型式（圖13）。3104型機械密封中的字母“B”表示平衡型密封，其余結(jié)構(gòu)和104型完全相同。B104型密封相當(dāng)于舊標(biāo)準（JB1472－75）的110型(GY型)。兩種密封型式工作條件基本相同，僅壓力不同。密封腔內(nèi)的溫度一20～80℃，轉(zhuǎn)速不大于3000r／min，介質(zhì)為清水、油類及其它弱腐蝕性液體。104型密封腔中的壓力為0～0．8MPa，而B104型適用壓力為0．6～3．0MPa。經(jīng)過二十多年的實踐，證明這兩種密封結(jié)構(gòu)簡單，使用可靠。因此。漢中襄樊五二五泵用機械密封選型。自貢襄樊五二五泵用機械密封廠家</p><p

磨損較均勻；從受力角度考慮過窄不利，破壞和變形的可能性增加了＞俐，密封端面的直徑又是載荷系數(shù)的函數(shù)。因此，密封端面的寬度應(yīng)綜合考慮。一般地講，對普通介質(zhì)密封端面隨直徑的增大而加寬。對于輕烴類介質(zhì)，端面寬度比在普通介質(zhì)中寬一些：而高速機械密封，端面寬度相對地窄一些，否則發(fā)熱量太大，不能正常運轉(zhuǎn)，一般在3mm左右。環(huán)直徑（mm、環(huán)寬（mm）－20～602～460～1004～6100～2005—7四、密封環(huán)的技術(shù)要求：1）密封端面的平面度不大于0．0009mm（即三個單色光干涉帶）；硬質(zhì)材料密封端面粗糙度Ra值不大于0．2μm（相當(dāng)于Δ10）；軟質(zhì)材料密封端面粗糙度Ra值不大于0．4μm(相當(dāng)于Δ9)，表面不應(yīng)有裂紋、劃傷、氣孔和疏松等影響使用性能的缺陷。2）密封環(huán)的密封端面與輔助密封圈接觸的端面平行度按GBll84－80的7級精度規(guī)定。3）密封環(huán)端面與安裝輔助密封圈的內(nèi)（或外）圓表面的垂直度應(yīng)按GBll84－80的7級精度的規(guī)定。4）密封環(huán)與輔助密封圈接觸部位的表面粗糙度凡值不大于3．2μm；外圓或內(nèi)孔尺寸公差為hg或Hg。上述要求是對普通泵用機械密封的密封環(huán)而言，對轉(zhuǎn)速較低的釜用機械密封可適當(dāng)放寬或參考相應(yīng)的標(biāo)準，而對高速機械密封則要求更高。五、平面度平面度。石家莊泵用機械密封安裝</p></p><br
