化學(xué)工業(yè)所采用的傳統(tǒng)密封設(shè)計(jì)，其密封壓力施加于旋轉(zhuǎn)面上，這種密封稱之為旋轉(zhuǎn)密封，因?yàn)閺椈苫虿y密封裝置與主軸一起旋轉(zhuǎn)。比較新穎的設(shè)計(jì)，其彈簧或波紋密封裝置安裝于靜止面上。在現(xiàn)在的機(jī)械密封上，上述兩種密封方式都有非常普遍的應(yīng)用，這樣對(duì)于安裝具有一定的靈活性。早期設(shè)計(jì)的許多機(jī)械密封采用單一的大型彈簧圍繞主軸排列，在液泵起動(dòng)過程中，可為密封面提供很強(qiáng)的密封力。密封的作用依靠主軸的旋轉(zhuǎn)來繃緊彈簧卷。采用多個(gè)較小的彈簧，可對(duì)密封面產(chǎn)生比較平均的負(fù)荷壓力，因此對(duì)堵塞具有更大的敏感性。后期設(shè)計(jì)的密封(見圖2)采用一系列較小的彈簧，排列于主軸的周圍，可對(duì)密封面產(chǎn)生比較均勻的負(fù)荷壓力。由于較小的彈簧可以事先安裝，因此大部分這類密封完全與所泵的液體相隔離。金屬波紋管密封裝置一般應(yīng)用于腐蝕性較強(qiáng)的液體。對(duì)許多腐蝕性較強(qiáng)的應(yīng)用領(lǐng)域，通用的設(shè)計(jì)是采用金屬波紋管密封裝置。該波紋管由一系列的金屬圓盤焊接而成，形成一個(gè)防止?jié)B漏的波紋密封裝置(見圖3)。采用這一裝置可使密封面之間的密封壓力更加均勻，而且在密封面上不需要增加二次密封，這樣自然就不會(huì)產(chǎn)生任何腐蝕磨損現(xiàn)象。一般來說，雖然其主要的密封壓力依賴于填料盒本身的壓力。GY機(jī)械密封大興安嶺單端機(jī)械密封。</p><div

多級(jí)離心泵機(jī)械密封問題解析1、沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)置不合理多級(jí)離心泵機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效地保護(hù)密封面，起到冷卻、潤(rùn)滑、沖走雜物等作用。有時(shí)設(shè)計(jì)員沒有合理地配置輔助沖洗系統(tǒng)，達(dá)不到密封效果；有時(shí)雖然設(shè)計(jì)人員設(shè)計(jì)了輔助系統(tǒng)，但由于沖洗液中有雜質(zhì)，沖洗液的流量、壓力不夠，沖洗口位置設(shè)計(jì)不合理等原因，也同樣達(dá)不到密封效果。2、振動(dòng)偏大機(jī)械密封振動(dòng)偏大，**終導(dǎo)致失去密封效果。但機(jī)械密封振動(dòng)偏大的原因往往不是機(jī)械密封本身的原因，多級(jí)離心泵的其它零部件是產(chǎn)生振動(dòng)的根源，如多級(jí)離心泵泵軸設(shè)計(jì)不合理、加工的原因、軸承精度不夠、聯(lián)軸器的平行度差、徑向力大等原因。3、多級(jí)離心泵汽蝕的原因由于裝置系統(tǒng)操作不合理以及工業(yè)多級(jí)鍋爐給水泵進(jìn)口汽蝕性能不好、泵的轉(zhuǎn)速偏高，在泵的入口處發(fā)生局部汽蝕，汽蝕發(fā)生后，水中會(huì)有氣泡，它一方面會(huì)沖擊機(jī)械密封面的外表面，使其表面出現(xiàn)破損；另一方面會(huì)使動(dòng)靜環(huán)的吻合面的流動(dòng)膜中也含有氣泡，不能形成穩(wěn)定的流動(dòng)膜，造成動(dòng)靜環(huán)的吻合面的干摩擦，使機(jī)械密封裝置損壞。4、機(jī)械加工精度不夠機(jī)械加工精度不夠，原因有很多，有的是機(jī)械密封本身的加工精度不夠。</p><p> 177°C）鍋爐給水和熱水，帶砂或管道渣子的臟的或被污染的流體和水，非聚合流體。PLAN52（帶無壓緩沖罐的串聯(lián)式密封）方案描述：外部?jī)?chǔ)液罐為配置外側(cè)密封提供緩沖液，正常操作時(shí)，由內(nèi)部輸液環(huán)保持循環(huán)，儲(chǔ)液罐連續(xù)排放蒸汽至蒸汽回收系統(tǒng)，并保持比密封腔壓力小。采用原因：外置機(jī)械密封是主機(jī)封，沒有或很少的工藝排放物，不允許工藝過程污染。應(yīng)用場(chǎng)合：應(yīng)用于雙端面非承壓密封（串聯(lián)），高蒸汽壓流體，輕質(zhì)烴，危險(xiǎn)/有毒流體，傳熱流體。PLAN53A（帶有壓密封液的雙端面密封）方案描述：外設(shè)加壓隔離液儲(chǔ)罐提供清潔液體給密封腔，循環(huán)由內(nèi)部輸液環(huán)完成。隔離液儲(chǔ)罐的壓力大于被密封工藝液體壓力。采用原因：隔離工藝流體，零工藝流體排放。應(yīng)用場(chǎng)合：應(yīng)用于雙端面承壓密封（雙重），高蒸汽壓流體，輕質(zhì)烴，危險(xiǎn)/有毒流體，傳熱流體，臟、腐蝕和聚合流體。PLAN53B（強(qiáng)制循環(huán)密封液的雙端面密封）方案描述：由外部管道系統(tǒng)為加壓雙端面密封裝置的外側(cè)密封提供液體，預(yù)先加了壓的氣囊蓄壓器提供壓力給循環(huán)系統(tǒng)，流動(dòng)由內(nèi)部輸液環(huán)來保持，循環(huán)系統(tǒng)中的熱量由空氣冷卻或水冷卻熱交換器除去。采用原因：分離工藝流體，零流程排放，比53A方案壓力高。新吳區(qū)波紋管機(jī)械密封件。</p><div

同時(shí)無壓雙重機(jī)械密封外側(cè)密封就能在維修前起到密封和容納泄漏液體的作用。對(duì)一些有毒、含顆粒介質(zhì)(或腐蝕性相當(dāng)厲害的介質(zhì))，一般可考慮以下方法：(1)采用合適的環(huán)境控制措施，如外沖洗+帶旋風(fēng)分離器的管路沖洗系統(tǒng)。(2)采用有壓雙重機(jī)械密封。有壓雙重機(jī)械密封隔離液的壓力高于介質(zhì)壓力，因而泵送介質(zhì)不會(huì)進(jìn)入密封腔。有壓雙重機(jī)械密封內(nèi)側(cè)密封起到阻止隔離液進(jìn)入泵腔的作用。因此當(dāng)輸送諸如粘性、磨蝕性及高溫介質(zhì)時(shí)，有壓雙重機(jī)械密封內(nèi)側(cè)密封由于沒有暴露在介質(zhì)中，因此可以不用昂貴的合金制作。有壓雙重機(jī)械密封外側(cè)密封**起到不使隔離液漏入大氣的作用。3、平衡型機(jī)械密封和非平衡型機(jī)械密封機(jī)械密封密封腔中的壓力作用在動(dòng)環(huán)上形成了閉合力，端面間的液膜形成開啟力。載荷系數(shù)K>1，密封為非平衡型機(jī)械密封。一般非平衡型機(jī)械密封只能用于低壓。當(dāng)壓力大于一定的限度，密封面間的液膜就會(huì)被擠出。在喪失液膜潤(rùn)滑及高負(fù)荷的作用下，機(jī)械密封的密封端面會(huì)很快損壞。非平衡型機(jī)械密封不能平衡液體對(duì)端面的作用，端面比壓隨流體壓力的上升而上升。載荷系數(shù)K<1，密封為平衡型機(jī)械密封。無錫輕型機(jī)械密封件。GY機(jī)械密封</p><p
