1、基本結構副葉輪動力密封通常由副葉輪、副葉片（又叫背葉片）、固定導葉和停車密封裝置等組成，如圖1所示。2、主要部件的作用（1）副葉片的作用是減低泵腔的壓力，達到平衡軸向力和防止顆粒進入密封裝置的目的，常用于抽送含有雜質的泵。（2）副葉輪實際是一個小離心泵葉輪，靠它產生的壓頭頂住工作葉輪出口的高壓液體向外泄漏。（3）固定導葉的作用是消除液體的旋轉，在無固定導葉時，副葉輪光背側的液體以角速度旋轉，壓力呈拋物線規(guī)律分布。副葉輪光背側下部的壓力小于副葉輪外徑處的壓力。如果有固定導葉，則可防止液體旋轉，光背側下部的壓力和副葉輪外徑處的壓力差不多，這就提高了副葉輪的封堵壓力。（4）油封（停車密封）作用。因為副葉輪只在泵運行時起密封作用，停車密封裝置可以在泵停車時，擋住該余壓液體往外泄漏。因此，停車密封應具備兩種功能：當停車時應確保及時封堵，以防泄漏；而運行時則應能及時松開，以免密封面磨損而耗能。在實際應用中，停泵密封采用了三道油封一道擋水環(huán)來起密封作用。將動力密封總成組裝好后替換離心泵機械密封總成即可。根據改進對象相應改變軸套及前后蓋板外型尺寸。泵除機械密封（或其它密封裝置）被替換外。三門峽襄樊五二五機械密封LC550/700LCF50/210I襄樊五二五機械密封。</p><div

機械密封作為凸輪轉子泵的重要組成部分，在水泵的運行中起到密封、防止介質泄漏的作用。我司售后維修人員在對污水泵進行維修時，發(fā)現(xiàn)有不少的問題是由機械密封的不當維護引起的。下面就為大家介紹四點機械密封的維護要點。1、新舊密封更新相對而言使用新機械密封的效果好于舊的，但新機械密封的質量或材質選擇不當時，配合尺寸誤差較大會影響密封效果；在聚合性滲透性介質中，靜環(huán)如無過度磨損，還是不更換為好。因為靜環(huán)在靜環(huán)座中長時間處于靜止狀態(tài)，使聚合物和雜質沉積為一體，起到了較好的密封作用。2、密封拆修一旦出現(xiàn)機械密封泄漏便急于拆修，其實，有時密封并沒有損壞，只需調整工況或適當調整密封就可消除泄漏。這樣既避免浪費又可以驗證自己的故障判斷能力，積累維修經驗提高檢修質量。3、潤滑對機械密封端面應進行適當潤滑，這樣可減少磨損和延長壽命，部分摩擦熱也可由潤滑劑帶走。一般潤滑劑可由介質本身承擔，因此密封端面（動環(huán)、靜環(huán)）見彈簧壓力不應過大。4、沖洗冷卻泵用機械密封工作使端面上產生的熱量應及時傳遞出去，否則端面間的液膜就會汽化而形成干摩擦，必須考慮沖洗冷卻措施。一般沖洗冷卻液采用內部密封介質，也可采用外部供水冷卻沖洗。</p><p> 旋轉的波紋管機械密封有自清洗的離心作用，這可以減少波紋管**沉積和內側結焦。b)對摩擦副組對材料，建議使用“硬對硬”結構，一般采用碳化鎢對碳化鎢(其中選YG6-YG6)和碳化鎢對碳化硅。選用“硬對硬”結構，必須注意以下兒個問題:1)冷卻系統(tǒng)要保障，禁止冷卻水中斷，以防端而升高，潤滑膜閃蒸而降低密封端面的潤滑，加劇磨損;2)機械密封在安裝過程中，要給密封端而澆一些潤滑油(機油或黃油均可)。以防止起泵時。密封端面由于缺乏潤滑而造成的干摩擦;3)采用清潔的外沖洗是解決溶劑顆粒堆積的比較有效的方法之一，但這種方法浪費較大，而且各種泵的介質、溫度、壓力(一般要求沖洗液壓力比介質側壓力高.12MPa)又各不相同，外沖洗系統(tǒng)結構就更繁雜，加之外沖洗設施的投入以及維護費用的消耗，有時會造成弊大一于利，尤其是一些中小型業(yè)。因此許多企業(yè)的封油系統(tǒng)棄之不用，或者就沒有設這套系統(tǒng)，針對這些情況，建議使用配用隔離介質的多密封結構，如油漿泵、回煉油泵等，使用雙端而機械密封，在兩組密封端面之間充滿隔i離介質(干凈的機油等)，如圖3所示。這種結構可有效地延一長機械密封的使用壽命，一般可達6000-8000h以上。另外。IHE襄樊五二五機械密封。</p><div

對石化行業(yè)來說，高溫重質油泵用機械密封的選用一直是一大難題，例如催化裂化油漿泵、回煉油泵、常壓塔底泵、初餾塔底泵、減壓塔底泵、延遲焦化的輻射進料泵等。高溫重質油泵的介質具有以下共同的特點:溫度高:一般在340一400℃;介質粘度大:在溫度下一般運動粘度為(12一180)X10一6m/s;介質有顆粒:如催化劑、焦炭、含有砂粒等其他雜質。對于高溫重油介質泵用機械密封?，F(xiàn)在各個企業(yè)都采用焊接金屬波紋管械密封?，F(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結構，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。針對波紋管內側結焦和結炭以及含固體顆粒等情況，解決的辦法有關資料己做了相關說明，比如采用蒸汽吹掃、摩擦副采用“硬對硬”、采用外沖洗等等，這些在一定程度上起到了較好的作用，這里不再過多闡述。但是以前提出的各種方法再實際應用中由于種種因素的影響效果不夠理想。為了更好的提高機械密封的使用壽命，節(jié)資降耗，針對各種情況，建議應把以下措施綜合起來采用:a)將金屬波紋升設計成旋轉型結構。襄樊五二五機械密封HTM-60D351。三門峽襄樊五二五機械密封LC550/700</p><p
