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(guó)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(shuō)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(lái)區(qū)分普通機(jī)械密封與特種機(jī)械密封.例如，英國(guó)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(lái)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(lái)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(lái)，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(zhǎng)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(lái)越苛刻。</p><p>

機(jī)械密封是一種旋轉(zhuǎn)機(jī)械的軸封裝置，機(jī)械密封又叫端面密封，在國(guó)家有關(guān)標(biāo)準(zhǔn)中是這樣定義的:"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(或磁力)的作用以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置"。常用機(jī)械密封結(jié)構(gòu)由靜止環(huán)(靜環(huán))、旋轉(zhuǎn)環(huán)(動(dòng)環(huán))、彈性元件彈簧座、緊定螺釘、旋轉(zhuǎn)環(huán)輔助密封圈和靜止環(huán)輔助密封圈等元件組成，防轉(zhuǎn)銷固定在壓蓋上以防止靜止環(huán)轉(zhuǎn)動(dòng)。機(jī)械密封在日常檢修中，常常會(huì)存在以下幾個(gè)誤區(qū)：誤區(qū)一：彈簧壓縮量越大密封效果越好？！其實(shí)不然，彈簧壓縮量過(guò)大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損；過(guò)度的壓縮使彈簧失去調(diào)節(jié)動(dòng)環(huán)端面的能力，導(dǎo)致密封失效。誤區(qū)二：動(dòng)環(huán)密封圈越緊越好？！其實(shí)動(dòng)環(huán)密封圈過(guò)緊有害無(wú)益。一是加劇密封圈與軸套間的磨損，泄漏；二是增大了動(dòng)環(huán)軸向調(diào)整、移動(dòng)的阻力，在工況變化頻繁時(shí)無(wú)法適時(shí)進(jìn)行調(diào)整；三是彈簧過(guò)度疲勞易損壞；四是使動(dòng)環(huán)密封圈變形，影響密封效果。誤區(qū)三：靜環(huán)密封圈越緊越好？！靜環(huán)密封圈基本處于靜止?fàn)顟B(tài)，相對(duì)較緊密封效果會(huì)好些，但過(guò)緊也是有害的。一是引起靜環(huán)密封因過(guò)度變形，影響密封效果；二是靜環(huán)材質(zhì)以石墨居多，一般較脆，過(guò)度受力極易引起碎裂。山西格蘭富泵用機(jī)械密封型號(hào)。西城區(qū)螺桿泵用機(jī)械密封件</p><p
