可分為旋轉(zhuǎn)式和靜止式機(jī)械密封。補(bǔ)償機(jī)構(gòu)隨軸旋轉(zhuǎn)的稱為旋轉(zhuǎn)式機(jī)械密封（圖2）；補(bǔ)償機(jī)構(gòu)不旋轉(zhuǎn)的（安裝在壓蓋內(nèi)）稱為靜止式機(jī)械密封（圖3）。補(bǔ)償機(jī)構(gòu)旋轉(zhuǎn)時(shí)易產(chǎn)生質(zhì)量不平衡，同時(shí)消耗攪拌功率，因此，旋轉(zhuǎn)式密封不能用于高速；而靜止式密封可用于高速。但是旋轉(zhuǎn)式密封安裝較方便，所以，普通的機(jī)械密封大多采用旋轉(zhuǎn)式結(jié)構(gòu)。按靜環(huán)的安裝位置可分為內(nèi)裝式和外裝式機(jī)械密封。靜環(huán)裝于密封壓蓋（或相當(dāng)于密封壓蓋的零件）內(nèi)側(cè)（即面向主機(jī)工作腔側(cè)）的機(jī)械密封稱為內(nèi)裝式機(jī)械密封（如圖1）；反之，在密封壓蓋的外側(cè)安裝靜環(huán)時(shí)稱為外裝式機(jī)械密封（圖4）。內(nèi)裝式機(jī)械密封可用于溫度和壓力較高，以及介質(zhì)對動環(huán)及彈性元件的腐蝕性不高的工況。外裝式機(jī)械密封適用于低壓（或負(fù)壓）和介質(zhì)具有腐蝕性的工況。(圖4)密封流體在密封端面間的泄漏方向和離心力方向相反的機(jī)械密封稱為內(nèi)流型機(jī)械密封；密封流體在密封端面間的泄漏方向與離心力方向相同時(shí)稱為外流型機(jī)械密封。一般情況下，內(nèi)流型機(jī)械密封多出現(xiàn)在內(nèi)裝式機(jī)械密封中（如圖1、2、3），而外裝式機(jī)械密封多屬于外流型機(jī)械密封（如圖4）。由于外流型泄漏方向和離心力方向相同，所以外流型機(jī)械密封泄漏量較大。因此。延安格蘭富泵用機(jī)械密封泄露。</p><div

再經(jīng)擴(kuò)散管排出，這個(gè)過程稱為壓水過程。同時(shí)，由于葉輪中心的流體流向邊緣，在葉輪中心形成低壓區(qū)，當(dāng)它具有足夠的真空時(shí)，在吸入端壓強(qiáng)的作用下（一般是大氣壓強(qiáng)），流體經(jīng)吸入室進(jìn)入葉輪，這個(gè)過程稱為吸水過程。由于葉輪連續(xù)的旋轉(zhuǎn)，流體也就連續(xù)的排出、吸入，形成連續(xù)的工作。離心式的泵（包括渣漿泵）的工作過程，實(shí)際上是一個(gè)能量傳遞和轉(zhuǎn)化的過程。它將電動機(jī)高速旋轉(zhuǎn)的機(jī)械能，通過泵的葉片傳遞并轉(zhuǎn)化為被抽升流體的壓能和動能。行業(yè)用途渣漿泵的用途渣漿泵可用于礦山，電力、冶金、煤炭、環(huán)保等行業(yè)輸送含有磨蝕性固體顆粒的漿體。如冶金選礦廠礦漿輸送，火電廠水力除灰、洗煤廠煤漿及重介輸送，疏浚河道，河流清淤等。在化工產(chǎn)業(yè)，也可輸送一些含有結(jié)晶的腐蝕性漿體。首先，在選礦廠的應(yīng)用，80%左右都是用在礦山行業(yè)選礦廠。由于礦石初選工況較為惡劣，因此在這一工段，渣漿泵的使用壽命普遍較低。當(dāng)然，不同的礦石，磨蝕性也不一樣。如在精礦輸送等工段相對磨蝕性減小，泵的整體使用壽命也就較長。所以一般用戶在采購過程中經(jīng)常問到供應(yīng)商的產(chǎn)品的使用壽命問題時(shí)候，嚴(yán)格講任何一家生產(chǎn)商等都不會毫無根據(jù)的為用戶承諾一個(gè)準(zhǔn)確使用壽命周期。貴陽襄樊五二五泵用機(jī)械密封廠家。大連耐腐蝕泵用機(jī)械密封</p><p

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，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)，動靜之間有間隙存在時(shí)，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(yán)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。現(xiàn)在軸封裝置一般采用機(jī)械密封。大連耐腐蝕泵用機(jī)械密封</p></p><br
