機(jī)械密封因其密封性好和使用壽命長等優(yōu)點(diǎn)，用于石油化工和其它工業(yè)部門，ACP200-400.5S機(jī)械密封.但是，如果對機(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，各國大的密封公司都有密封技術(shù)培訓(xùn)中心，指導(dǎo)用戶如何正確使用機(jī)械密封.我國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.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、規(guī)格和材質(zhì)證明，零件的數(shù)量，動(dòng)、靜環(huán)配對是否符合圖紙要求，零件上有無制造廠的識別標(biāo)記;3.檢查各零件的表面質(zhì)t，特別是動(dòng)、靜環(huán)的密封端面有無碰傷、劃痕，如有損壞，必須進(jìn)行修復(fù)或更換，ACP200-400.5S機(jī)械密封，零件表面必須清洗干凈，在動(dòng)、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，如果沒有試壓證明，安裝前要補(bǔ)做水壓試驗(yàn)，ACP200-400.5S機(jī)械密封，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。阜陽橡膠波紋管機(jī)械密封件。ACP200-400.5S機(jī)械密封</p><div

要掌握機(jī)械密封檢修與維護(hù)，首先要知道機(jī)械密封的工作原理。機(jī)械密封是由兩塊密封元件（靜環(huán)與動(dòng)環(huán)）垂直于軸的、光潔而平直的表面相互貼合，并作相對轉(zhuǎn)動(dòng)而構(gòu)成的密封裝置。它是靠密封介質(zhì)的壓力在旋轉(zhuǎn)的動(dòng)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(gè)端面緊密結(jié)合，端面間維持一層極薄的液體膜而達(dá)到密封目的的。這層液體膜具有液體動(dòng)壓力與靜壓力，起著潤滑和平衡力的作用。水泵機(jī)械密封的檢修工藝主要有以下個(gè)方面：一．機(jī)械密封的清掃與檢查機(jī)械密封的工作原理要求機(jī)械密封內(nèi)部無任何雜質(zhì)。在組裝機(jī)械密封前要徹底清掃動(dòng)環(huán)、靜環(huán)、軸套等部件。重點(diǎn)檢查：1、動(dòng)靜環(huán)（5、6）表面是否存在劃痕、裂紋等缺陷，這些缺陷存在會(huì)造成機(jī)械密封嚴(yán)重漏泄。有條件的可以用**工具檢查密封面是否平整，密封面不平整，壓力水會(huì)進(jìn)入組裝后機(jī)械密封的動(dòng)靜環(huán)密封面，將動(dòng)靜環(huán)分開，機(jī)械密封失效。必要時(shí)可以制作工裝在組裝前水壓試驗(yàn)。2、檢查動(dòng)靜環(huán)座（2）是否存在影響密封的缺陷。如動(dòng)靜環(huán)座與動(dòng)靜環(huán)密封膠圈配合表面是否存在傷痕等缺陷。3、檢查機(jī)械密封補(bǔ)償彈簧（7）是否損壞及變形，倔強(qiáng)系數(shù)是否變化。4、檢查密封軸套（8）是否存在毛刺、溝痕等缺陷。ACP200-400.5S機(jī)械密封江陰水泵機(jī)械密封件。</p><div
