機(jī)械密封因其密封性好和使用壽命長(zhǎng)等優(yōu)點(diǎn)，用于石油化工和其它工業(yè)部門(mén).但是，如果對(duì)機(jī)械密封安裝不當(dāng)、操作維護(hù)不善，也會(huì)經(jīng)常發(fā)生事故，那時(shí)機(jī)械密封還不如填料密封受人歡迎.因?yàn)闄C(jī)械密封屬于較精密的部件，所以，正確的安裝程序，嚴(yán)格的操作規(guī)范，合理的維護(hù)保養(yǎng)制度是保證機(jī)械密封性能和正常運(yùn)行的有力措施.為此，各國(guó)大的密封公司都有密封技術(shù)培訓(xùn)中心，指導(dǎo)用戶(hù)如何正確使用機(jī)械密封.我國(guó)也有幾位出名的密封學(xué)者，經(jīng)常舉辦密封技術(shù)講學(xué)班，旨在推廣機(jī)械密封的正確使用，HB200-150-18機(jī)械密封.機(jī)械密封安裝一、安裝前的準(zhǔn)備工作和注意事項(xiàng)1.從包裝箱中取出要安裝的機(jī)械密封放在干凈的平面上，保護(hù)好密封面，并將所有標(biāo)簽、證件整理后待檢;2.檢查機(jī)械密封的型號(hào)、規(guī)格和材質(zhì)證明，零件的數(shù)量，動(dòng)、靜環(huán)配對(duì)是否符合圖紙要求，零件上有無(wú)制造廠的識(shí)別標(biāo)記;3.檢查各零件的表面質(zhì)t，特別是動(dòng)、靜環(huán)的密封端面有無(wú)碰傷、劃痕，如有損壞，必須進(jìn)行修復(fù)或更換，HB200-150-18機(jī)械密封，零件表面必須清洗干凈，在動(dòng)，HB200-150-18機(jī)械密封、靜環(huán)密封端面上涂一層油;4.檢查石墨環(huán)、城充聚四氛乙烯壞及組裝的動(dòng)、靜環(huán)的水壓試驗(yàn)證明，如果沒(méi)有試壓證明，安裝前要補(bǔ)做水壓試驗(yàn)，試驗(yàn)壓力照第六章一節(jié)規(guī)定;5.并圈彈簧傳動(dòng)的機(jī)械密封。大興安嶺單端機(jī)械密封。HB200-150-18機(jī)械密封</p><div

泵用機(jī)械密封種類(lèi)繁多，型號(hào)各異，但泄漏點(diǎn)主要有五處：1)、軸套與軸間的密封；2)、動(dòng)環(huán)與軸套間的密封；3)、動(dòng)、靜環(huán)間密封；4)、對(duì)靜環(huán)與靜環(huán)座間的密封；5)、密封端蓋與泵體間的密封；1、安裝靜試時(shí)泄漏機(jī)械密封安裝調(diào)試好后，一般要進(jìn)行靜試，觀察泄漏量。如泄漏量較小，多為動(dòng)環(huán)或靜環(huán)密封圈存在問(wèn)題；泄漏量較大時(shí)，則表明動(dòng)、靜環(huán)摩擦副間存在問(wèn)題。在初步觀察泄漏量、判斷泄漏部位的基礎(chǔ)上，再手動(dòng)盤(pán)車(chē)觀察，若泄漏量無(wú)明顯變化則靜、動(dòng)環(huán)密封圈有問(wèn)題；如盤(pán)車(chē)時(shí)泄漏量有明顯變化則可斷定是動(dòng)、靜環(huán)摩擦副存在問(wèn)題；如泄漏介質(zhì)沿軸向噴射，則動(dòng)環(huán)密封圈存在問(wèn)題居多，泄漏介質(zhì)向四周?chē)娚浠驈乃鋮s孔中漏出，則多為靜環(huán)密封圈失效。此外，泄漏通道也可同時(shí)存在，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。2、試運(yùn)轉(zhuǎn)時(shí)出現(xiàn)的泄漏泵用機(jī)械密封經(jīng)過(guò)靜試后，運(yùn)轉(zhuǎn)時(shí)高速旋轉(zhuǎn)產(chǎn)生的離心力，會(huì)壓制介質(zhì)的泄漏。因此，試運(yùn)轉(zhuǎn)時(shí)機(jī)械密封泄漏在排除軸間及端蓋密封失效后，基本上都是由于動(dòng)、靜環(huán)摩擦副受破壞所致。引起摩擦副密封失效的因素主要有：1)、操作中，因抽空、氣蝕、憋壓等異?，F(xiàn)象，引起較大的軸向力，使動(dòng)、靜環(huán)接觸面分離。蕪湖YM109機(jī)械密封件。</p><div
