一、準(zhǔn)備工作1.更換水泵機(jī)械密封前要認(rèn)真檢查集結(jié)密封零件數(shù)量是否足夠，各元件是否有損壞，特別是動(dòng)、靜環(huán)有無碰傷、裂紋和變形等缺陷。如果有問題，需進(jìn)行修復(fù)或更換新備件。2.檢查軸套或壓蓋的倒角是否恰當(dāng)，如不符合要求則必須進(jìn)行修整。3.水泵機(jī)械密封各元件及其有關(guān)的裝配接觸面，在安裝前必須用**或無水酒精清洗干凈。安裝過程中應(yīng)保持清潔，特別是動(dòng)、靜環(huán)及輔助密封元件應(yīng)無雜質(zhì)、灰塵。動(dòng)、靜環(huán)表面涂上一層清潔的機(jī)油或透平油。二、安裝工作1.上緊壓蓋應(yīng)在聯(lián)軸器找正后進(jìn)行。螺栓應(yīng)均勻上緊，防止壓蓋斷面偏斜，用塞尺或**工具檢查各點(diǎn)，其誤差不大于。2.檢查壓蓋與軸或軸套外徑的配合間隙（及同心度），必須保證四周均勻，用塞尺檢查各點(diǎn)允差不大于。3.彈簧壓縮量要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象，要求誤差±，過大會增加斷面比壓，加速斷面磨損。過小會造成比壓不足而不能起到密封作用，彈簧裝上后在彈簧座內(nèi)要移動(dòng)靈活。用單彈簧時(shí)要注意彈簧的旋向，彈簧的旋向應(yīng)與軸的轉(zhuǎn)動(dòng)方向相反。4.水泵機(jī)械密封動(dòng)環(huán)安裝后須保持靈活移動(dòng)，將動(dòng)環(huán)壓向彈簧后應(yīng)能自動(dòng)彈回來。5.先將水泵機(jī)械密封靜環(huán)密封圈套在靜環(huán)背部后，再裝入密封端蓋內(nèi)。注意保護(hù)靜環(huán)斷面。南昌柳州酸王泵用機(jī)械密封700HDT-5800-18HB150-125-24柳州酸王泵用機(jī)械密封。</p><div

泵用機(jī)械密封件在運(yùn)行過程中可能會遇到一些故障以及問題，這可能會使安裝過程中沒有正常的操作導(dǎo)致的，因此在進(jìn)行安裝的時(shí)候一定要進(jìn)行多方面的檢查，主要有：1、泵用機(jī)械密封件腔孔徑及深度尺寸應(yīng)該與密封組裝圖上尺寸一致，一般偏差為±±±。軸的軸向竄量檢查，總的軸向竄量不能超過，軸的徑向跳動(dòng)一般小于。徑向跳動(dòng)過大，有可能造成：軸或軸套的磨損;密封面之間泄漏量增加;設(shè)備的振動(dòng)加劇從而降低密封的壽命。2、軸的彎曲度檢查。軸的比較大彎曲度應(yīng)小于。密封腔表面的跳動(dòng)檢查，密封腔表面的跳動(dòng)不能超過。密封腔表面如與軸不垂直，有可能造成機(jī)械密封一系列的故障。因?yàn)槊芊鈮荷w是靠螺栓固定在密封壓蓋上的，密封腔跳動(dòng)過大，造成壓蓋安裝傾斜，依次就造成密封靜環(huán)傾斜，從而導(dǎo)致整個(gè)密封不正?；蝿?dòng)，這是產(chǎn)生微振磨損的主要原因，另外機(jī)械密封與軸或軸套的輔助密封磨損也將加劇，再有就是密封的不正常晃動(dòng)也將造成金屬波紋管或傳動(dòng)銷的磨損和疲勞，導(dǎo)致密封的過早失效。3、泵用機(jī)械密封件腔孔與軸的對中度檢查，不對中度應(yīng)小于。密封腔孔與軸不對中，將會影響密封面之間的動(dòng)載荷，從而縮短密封的運(yùn)轉(zhuǎn)壽命。調(diào)整該對中度。晉中柳州酸王泵用機(jī)械密封。</p><div

在機(jī)械密封水泵的常見故障中，機(jī)械密封的故障大約占整個(gè)維修工作量的一半?？梢姍C(jī)械密封在機(jī)泵維修中所占的位置。由于機(jī)泵所輸送的介質(zhì)千差萬別，工藝條件各不相同，所以了解這些情況對機(jī)封的選擇及維護(hù)很重要。結(jié)合多年來在機(jī)封選擇和維修中的經(jīng)驗(yàn)，介紹幾種特殊工況下機(jī)械密封的工作特點(diǎn)和注意事項(xiàng)。一、高溫下的機(jī)械密封一般情況下，介質(zhì)的溫度超過120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。為保證機(jī)械密封在高溫環(huán)境下正常工作，可以采取如下措施：1、給機(jī)封增加冷卻沖洗裝置。2、選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成。南昌柳州酸王泵用機(jī)械密封。南昌柳州酸王泵用機(jī)械密封700HDT-5800-18</p><p

四、機(jī)封安裝示意圖以單級臥式雙吸油泵為例步驟一：泵解體步驟二：檢查軸套光潔度及測繪步驟三：打磨軸套和清理端面步驟四：軸套、機(jī)封潤滑步驟五：安裝機(jī)封步驟六：恢復(fù)泵體和調(diào)整步驟七：定位塊拆除和盤車調(diào)試五、拆卸注意事項(xiàng)1、在安裝、拆卸機(jī)械密封時(shí)要仔細(xì)，嚴(yán)禁動(dòng)用手錘和扁鏟，以免損壞密封元件。如果結(jié)垢拆卸不下時(shí)，應(yīng)清洗干凈后再進(jìn)行拆卸。2、如果在泵兩端都用機(jī)械密封時(shí)，在裝配，拆卸過程中互相照顧，防止顧此失彼。對運(yùn)行過的機(jī)械密封，凡有壓蓋松動(dòng)使密封發(fā)生移動(dòng)的情況，則動(dòng)靜環(huán)零件必須更換，不應(yīng)重新上緊繼續(xù)使用。因?yàn)樗蓜?dòng)后摩擦副原來運(yùn)轉(zhuǎn)軌跡會發(fā)生變動(dòng)，接觸面的密封性就很容易遭到破壞。拆卸機(jī)械密封順序如下：1、裝上定位塊；2、去掉定位螺釘；3、沖洗接管和壓蓋螺栓；4、取出機(jī)械密封。六、機(jī)封的維護(hù)1、啟動(dòng)與停運(yùn)準(zhǔn)備工作：啟動(dòng)前保持密封腔充滿液體，防止干磨；待冷卻后才可停冷卻水，否則容易引起較大的熱脹冷縮使得O圈失效。2、運(yùn)轉(zhuǎn)時(shí)注意事項(xiàng)：泵啟動(dòng)后若有輕微泄漏現(xiàn)象，應(yīng)觀察一段時(shí)間，如連續(xù)運(yùn)行4小時(shí)，泄漏量仍不減小，則應(yīng)停泵檢查；泵的操作壓力應(yīng)平穩(wěn)，泵在運(yùn)轉(zhuǎn)中應(yīng)避免發(fā)生抽空現(xiàn)象，以免造成密封面干摩擦及密封破壞。南昌柳州酸王泵用機(jī)械密封700HDT-5800-18</p></p><br
