對策：油室腔內(nèi)潤滑油面高度應(yīng)加到高于動、靜環(huán)密封面。（3）轉(zhuǎn)子周期性振動。原因是定子與上、下端蓋未對中或葉輪和主軸不平衡，汽蝕或軸承損壞（磨損），這種情況會縮短密封壽命和產(chǎn)生滲漏。對策：可根據(jù)維修標(biāo)準(zhǔn)來糾正上述問題。2、由于壓力產(chǎn)生的滲漏（1）高壓和壓力波造成的機(jī)械密封滲漏由于彈簧比壓力及總比壓設(shè)計過大和密封腔內(nèi)壓力超過3MPa時，會使密封端面比壓過大，液膜難以形成，密封端面磨損嚴(yán)重，發(fā)熱量增多，造成密封面熱變形。對策：在裝配機(jī)封時，彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象，丹東格蘭富機(jī)械密封件CR10-05，高壓條件下的機(jī)械密封應(yīng)采取措施。為使端面受力合理，盡量減小變形，可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料，并加強(qiáng)冷卻的潤滑措施。（2）真空狀態(tài)運(yùn)行造成的機(jī)械密封滲漏泵在起動、停機(jī)過程中，由于泵進(jìn)口堵塞，抽送介質(zhì)中含有氣體等原因，有可能使密封腔出現(xiàn)負(fù)壓，密封腔內(nèi)若是負(fù)壓，會引起密封端面干摩擦，內(nèi)裝式機(jī)械密封會產(chǎn)生漏氣（水）現(xiàn)象，真空密封與正壓密封的不同點(diǎn)在于密封對象的方向性差異，而且機(jī)械密封也有其某一方向的適應(yīng)性。對策：采用雙端面機(jī)械密封，丹東格蘭富機(jī)械密封件CR10-05，這樣有助于改善潤滑條件，提高密封性能。3，丹東格蘭富機(jī)械密封件CR10-05、由于介質(zhì)引起的滲漏。平鄉(xiāng)格蘭富機(jī)械密封件。丹東格蘭富機(jī)械密封件CR10-05</p><div

1）大多數(shù)潛污泵機(jī)械密封拆解后，靜環(huán)和動環(huán)的輔助密封件無彈性，有的已經(jīng)腐爛，造成了機(jī)封的大量滲漏甚至有磨軸的現(xiàn)象。由于高溫、污水中的弱酸、弱堿對靜環(huán)和動環(huán)輔助橡膠密封件的腐蝕作用，造成了機(jī)械滲漏過大，動、靜環(huán)橡膠密封圈材料為丁腈—40，不耐高溫，不耐酸堿，當(dāng)污水為酸性堿性時易腐蝕。對策：對腐蝕性介質(zhì)，橡膠件應(yīng)選用耐高溫、耐弱酸、弱堿的氟橡膠。（2）固體顆粒雜質(zhì)引起的機(jī)械密封滲漏如果固體顆粒進(jìn)入密封端面，將會劃傷或加快密封端面的磨損，水垢和油污在軸（套）表面的堆積速度超過摩擦副的磨損速度，致使動環(huán)不能補(bǔ)償磨耗位移，硬對硬摩擦副的運(yùn)轉(zhuǎn)壽命要比硬對石墨摩擦副的長，因?yàn)楣腆w顆粒會嵌入石墨密封環(huán)的密封面內(nèi)。對策：在固體顆粒容易進(jìn)入的位置應(yīng)選用碳化鎢對碳化鎢摩擦副的機(jī)械密封。4、因其他問題引起的機(jī)械密封滲漏機(jī)械密封中還存在設(shè)計、選擇、安裝等不夠合理的地方。（1）彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象，誤差±2mm，壓縮量過大增加端面比壓，摩擦熱量過多，造成密封面熱變形和加速端面磨損，壓縮量過小動靜環(huán)端面比壓不足，則不能密封。（2）安裝動環(huán)密封圈的軸（或軸套）端面及安裝靜環(huán)密封圈的密封壓蓋。</p><p> 由于填充物被密封介質(zhì)腐蝕而產(chǎn)生泄漏的現(xiàn)象在化工行業(yè)的用泵中也時有發(fā)生，因此對填充物的選擇也是密封考慮的因素之一。螺旋密封螺旋密封也是動力密封的一種形式，它是在旋轉(zhuǎn)的軸上或者在軸的包容套上加工出螺旋槽，軸和套之間充有密封介質(zhì)。軸的旋轉(zhuǎn)使螺旋槽產(chǎn)生類似于泵的輸送作用，從而阻止密封液的泄漏。其密封能力的大小與螺旋角度、螺距、齒寬、齒高、齒的作用長度以及軸與套之間的間隙大小有關(guān)。由于密封之間不發(fā)生磨擦，因而壽命長，但由于結(jié)構(gòu)空間的限制，其螺旋長度一般較短，因而其密封能力也受到局限。在泵降速使用時，其密封效果則會大打折扣。迷宮密封在設(shè)計合理，加工精良，裝配完好、轉(zhuǎn)速較高時，迷宮密封效果很好。但在實(shí)際應(yīng)用中，因此而產(chǎn)生的泄漏卻很多，分析其原因主要有：1、密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車刀痕在有些情況下也加大了泄漏趨勢。2、軸承室內(nèi)潤滑油注入量太多，其溢出壓力超過了密封阻力。3、油窗或油位計安裝位置有誤，誤導(dǎo)了人們對油室內(nèi)潤滑油量的正確判斷。4、運(yùn)轉(zhuǎn)中油溫的升高使其粘度降低，增加了泄漏的可能。5、回油槽或回油孔尺寸偏小，或受到其它障礙。湖北格蘭富機(jī)械密封件。</p><div

2、機(jī)械密封的沖洗狀況不符合設(shè)計要求。在輸送易結(jié)晶或有細(xì)小顆粒的介質(zhì)時，必須有一定壓力和一定流量的沖洗液進(jìn)行沖洗，否則其結(jié)晶體或者微粒會加速密封副的磨損，以及影響密封副磨損后的自動補(bǔ)償而發(fā)生泄漏。所以根據(jù)輸送介質(zhì)的性質(zhì)不僅要配置相應(yīng)的沖洗管路，更要安裝有監(jiān)控和調(diào)節(jié)功能的儀表和裝置，保證沖洗液的壓力和流量滿足設(shè)計要求，才能維持機(jī)封的正常工作，這一點(diǎn)往往被用戶所忽視。3、每種機(jī)械密封所能承受的壓力是有限度的，由于對密封腔內(nèi)的壓力測算不準(zhǔn)，造成密封腔內(nèi)的壓力超過了機(jī)械密封所能承受的壓力而產(chǎn)生泄漏，也是常見的密封失效原因之一。4、機(jī)械密封的工作溫度不能超過其規(guī)定值。在有冷卻管路的設(shè)計中，往往由于冷卻介質(zhì)的流量不足而使冷卻效果降低;在沒有冷卻管路的設(shè)計中，密封腔內(nèi)經(jīng)常由于窩存空氣而造成機(jī)械密封處于干磨擦狀態(tài)。這兩種情況都會使機(jī)械密封的運(yùn)動密封副工作溫度過高而加快磨損，導(dǎo)致密封失效。5、在使用單彈簧的機(jī)械密封時，忽略彈簧的旋轉(zhuǎn)方向與泵轉(zhuǎn)子轉(zhuǎn)動方向的正確組合也時有發(fā)生。或設(shè)計時沒有說明，或裝配時的疏忽，沒有做到因?yàn)檗D(zhuǎn)子的旋轉(zhuǎn)而使機(jī)械密封的彈簧力加大而是相反。丹東格蘭富機(jī)械密封件CR10-05</p></p><br
