機(jī)械密封，又稱端面密封，是一種用來解決旋轉(zhuǎn)軸與機(jī)體之間密封的裝置，常用于泵等旋轉(zhuǎn)式流體機(jī)械。因此，機(jī)械密封是一種通用的軸封裝置。機(jī)械密封分為接觸式和非接觸式兩種，目前多數(shù)采用接觸式機(jī)械密封，而非接觸式機(jī)械密封正在發(fā)展之中，并已引起人們注意。機(jī)械密封是機(jī)器上的非功能性零部件，但它在減少泄漏，穩(wěn)定生產(chǎn)上起了很大作用。1、機(jī)械密封的工作原理機(jī)械密封的工作原理就是以兩個(gè)相互貼合，平的與旋轉(zhuǎn)軸線垂直的密封表面，并相對(duì)轉(zhuǎn)動(dòng)的密封裝置。它是靠彈性元件(如彈簧或波紋管)和密封介質(zhì)的壓力，隨軸旋轉(zhuǎn)的動(dòng)環(huán)和不隨軸旋轉(zhuǎn)的靜環(huán)的接觸端而上產(chǎn)生適當(dāng)?shù)膲壕o力，使這兩個(gè)接觸端面緊密貼合，端面間維持一層極薄的液膜，從而達(dá)到密封的目的。2、機(jī)械密封的作用一、提高機(jī)器效率、降低能耗。1、減少機(jī)器的內(nèi)漏、外漏和穿漏，提高機(jī)器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機(jī)械密封，使泵效率提高。2、減少摩擦損失，提高機(jī)器的機(jī)械效率。例如，將雙端面密封改為單端面密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失，提高機(jī)械效率。3、改變密封方式，提高機(jī)器或機(jī)組的效率。例如。太原HRM3襄樊五二五機(jī)械密封襄樊五二五機(jī)械密封LC550/700。</p><div

將屏蔽泵改用機(jī)械密封泵，使電動(dòng)機(jī)效率提高;采用磁力傳動(dòng)泵，提高機(jī)器效率。4、改變輔助系統(tǒng)，減少能耗，提高機(jī)組效率。例如，熱油泵自沖洗改為小葉輪循環(huán)沖洗;雙端面密封改為單端面密封，節(jié)省封油輔助系統(tǒng)的能耗。二、節(jié)約原材料。例如，工藝流體回收，減少或消除動(dòng)力蒸汽和工藝流體的損耗，減少封油損耗等。三、提高機(jī)器可靠性。例如，軸封的漏損和壽命決定軸封和機(jī)器的可靠性。四、安全和環(huán)境保護(hù)。根據(jù)日本某廠調(diào)查報(bào)告，在發(fā)生的786件事故中有32件是泄漏造成的(占42%)。此外工藝流體泄漏還會(huì)造成環(huán)境污染，包括對(duì)大氣污染、水污染和車間環(huán)境污染。機(jī)械密封安裝、使用技術(shù)要領(lǐng)1.設(shè)備轉(zhuǎn)軸的徑向跳動(dòng)應(yīng)≤，軸向竄動(dòng)量不允許大于；2.設(shè)備的密封部位在安裝時(shí)應(yīng)保持清潔，密封零件應(yīng)進(jìn)行清洗，密封端面完好無損，防止雜質(zhì)和灰塵帶入密封部位；3.在安裝過程中嚴(yán)禁碰擊、敲打，以免使機(jī)械密封摩擦副破損而密封失效；4.安裝時(shí)在與密封相接觸的表面應(yīng)涂一層清潔的機(jī)械油，以便能順利安裝；5.安裝靜環(huán)壓蓋時(shí)，擰緊螺絲必須受力均勻，保證靜環(huán)端面與軸心線的垂直要求；6.安裝后用手推動(dòng)動(dòng)環(huán)，能使動(dòng)環(huán)在軸上靈活移動(dòng)，并有一定彈性；7.安裝后用手盤動(dòng)轉(zhuǎn)軸、轉(zhuǎn)軸應(yīng)無輕重感覺。</p><p>
