泵用機(jī)械密封種類繁多，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)向四周噴射或從水冷卻孔中漏出，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，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。</p><p> 腐蝕失效機(jī)械密封因腐蝕引起的失效為數(shù)不少，常見(jiàn)的腐蝕類型有如下幾種。1.表面腐蝕由于腐蝕介質(zhì)的侵蝕作用，機(jī)械密封件會(huì)發(fā)生表面腐蝕，嚴(yán)重時(shí)也可發(fā)生腐蝕穿孔，彈簧件更為明顯，采用不銹鋼材料，可減輕表面腐蝕。2.點(diǎn)腐蝕彈簧套常出現(xiàn)大面積點(diǎn)蝕或區(qū)域性點(diǎn)蝕，有的導(dǎo)致穿孔，此類局部腐蝕對(duì)密封使用尚不會(huì)造成很嚴(yán)重的后果，不過(guò)大修時(shí)也應(yīng)予更換。3.晶間腐蝕碳化鎢環(huán)不銹鋼環(huán)座以銅焊連接，使用中不銹鋼座易發(fā)生晶間腐蝕，為克服敏化的影響，不銹鋼應(yīng)進(jìn)行固溶處理。4.應(yīng)力腐蝕破裂金屬焊接波紋管、彈簧等在應(yīng)力與介質(zhì)腐蝕的共同作用下，往往會(huì)發(fā)生斷裂，由于彈簧的突然斷裂而使密封失效，一般采用加大彈簧絲徑加以解決。5.縫隙腐蝕動(dòng)環(huán)的內(nèi)孔與軸套表面之間、螺釘與螺孔之間，O形環(huán)與軸套之間，由于間隙內(nèi)外介質(zhì)濃度之差而導(dǎo)致縫隙腐蝕，此外陶瓷鑲環(huán)與金屬環(huán)座間也會(huì)發(fā)生縫隙腐蝕，一般在軸套表面噴涂陶瓷，鑲環(huán)處表面涂以黏結(jié)劑以減輕縫隙腐蝕。6.電化學(xué)腐蝕異種金屬在介質(zhì)中往往引起電化學(xué)腐蝕，它使鑲環(huán)松動(dòng)，影響密封，一般亦采取在鑲接處涂黏結(jié)劑的辦法予以克服。熱損失效1.熱裂如密封面處于干摩擦、冷卻突然中斷、雜質(zhì)進(jìn)入密封面、抽空等。岳陽(yáng)格蘭富機(jī)械密封件。</p><div

雖然其主要的密封壓力依賴于填料盒本身的壓力，但彈簧和波紋管可補(bǔ)償液泵在起動(dòng)和停機(jī)過(guò)程中因主軸運(yùn)動(dòng)的壓力不足，使密封面始終保持一定的密封壓力。腐蝕磨損問(wèn)題由于多種原因，例如包括軸承的公差、軸端余隙、振動(dòng)和主軸偏差，都會(huì)使液泵的主軸產(chǎn)生徑向和軸向運(yùn)動(dòng)。此外，由于將接觸面之間保持平行是十分困難的，因此機(jī)械密封本身的內(nèi)部產(chǎn)生移動(dòng)也是很正常的。這類移動(dòng)往往是由于設(shè)備和安裝公差、熱膨脹、管路應(yīng)力或主軸調(diào)試不當(dāng)所造成。為了使密封面之間始終保持互相配合，彈簧起到了機(jī)械密封與運(yùn)動(dòng)主軸之間的恒定調(diào)節(jié)作用。當(dāng)旋轉(zhuǎn)面和主軸之間采用人造橡膠密封時(shí)，該彈性體就會(huì)在主軸上來(lái)回運(yùn)動(dòng)。這種重復(fù)摩擦動(dòng)作，會(huì)磨蝕主軸上的防腐材料，失去主軸的氧化膜保護(hù)層，終會(huì)在主軸的摩擦面上形成磨損溝槽，造成液體從溝槽中泄漏，并增加必要的維修工作量或甚至更換主軸。為了解決這一問(wèn)題，一般在填料盒內(nèi)安裝一個(gè)可更換的軸套。然而，解決腐蝕磨損問(wèn)題的辦法是去除其內(nèi)部的動(dòng)態(tài)密封?，F(xiàn)在，大部分主要密封制造廠生產(chǎn)非腐蝕磨損型密封，以防止液泵零件的腐蝕磨損。平衡和非平衡式密封機(jī)械密封的平衡對(duì)接觸面的密封壓力有很大影響。重慶格蘭富機(jī)械密封件。重慶格蘭富機(jī)械密封件CR90-2-2</p><p
