七、目前應用的密封種類根據(jù)制造方法和材料的不同，目前應用的密封環(huán)有整體式密封環(huán)（用同一種材料制造）、組合式密封環(huán)、表面堆焊硬質合金和噴涂陶瓷等多種結構。整體式密封環(huán)種類：這種密封環(huán)因用同一種材料制成，材料的性能在密封環(huán)的各個部位均勻一致，沒有組合式密封環(huán)泄漏和分離的缺陷，也沒有電化學腐蝕的可能，SLJY40-200泵用機械密封。制造軟環(huán)大都用石墨，制造硬環(huán)時可用各種合金鋼，如軸承鋼（GCr9）、高速鋼（W18CrV）及其他合金鋼（如40Cr、3Cr13等），也有的用合金鑄鐵（如硅、鉻和鎳鑄鐵）。采用這些材料時，都要輔之以適當?shù)臒崽幚砉に?，以提高其硬度和耐磨性。這類材料價格較低，如果使用恰當，SLJY40-200泵用機械密封，也有較長的壽命。為了進一步提高硬度和延長使用壽命，可采用硬質合金制造。常用的硬質合金為鉆基碳化鎢，性能較好，但價格高，SLJY40-200泵用機械密封。鋼結硬質合金的價格較低。為了提高在腐蝕介質中的耐蝕性，有鎳基碳化鎢，而哈氏合金有更高的耐蝕性，但價格昂貴。此外，還有用碳化硅及其他陶瓷材料制造的密封環(huán)。出現(xiàn)組合式由封環(huán)的原因碳化鎢等材料有優(yōu)良的性能，但是價格高，加工困難，限制了它的使用。為解決這個矛盾，出現(xiàn)了組合式密封環(huán)。密封端面采用硬質合金，密封環(huán)的基體。北京格蘭富泵用機械密封型號。SLJY40-200泵用機械密封</p><div

這種結構類似形式很多(見圖4-8)，它的熱流體動力效應是在密封上形成，在密封環(huán)旋轉的時候，槽能使液體強烈地冷卻距它較遠的密封表面。進行這種冷卻時，在密封環(huán)的初始表面上形成與槽數(shù)相等的流體動力楔和高壓區(qū).由于切向流和壓力降，在每一個槽后形成慧星狀潤滑楔(圖10-14).因此，隨著密面上載荷與滑動速度的增加，摩擦系數(shù)反而減小(圖10-15).二、HSHF型高壓機械密封介紹芳烴裝置加料泵液力透平GAT-101A，功率968kW，轉速6748r/min，輸送介質為烴類，使用溫度43~39度，進口壓力，出口壓力，機械密封是布格曼公司HSHF型高壓密封，其定型產(chǎn)品為單端面、流體動壓式帶泵效螺旋的結構.原工作參數(shù)P=5(14)MPa,t=300'C,V<50m/s,因單端面密封結構不能滿足使用要求，所以采用雙端面結構，由一個動環(huán)對兩個靜環(huán)，結構比較緊湊，它是筒形結構，安裝比較方便之(圖10-16).用于液力透平進口端密封是HSHFD3/95規(guī)格，泵效套(6A)是右螺旋，泵效外殼(16A)是左螺旋;用于出口端密封是HSHFD4/95規(guī)格，泵效套(6B)是左螺旋，泵效外殼(16B)是右螺旋.因此，這兩套密封與旋轉方向有關，進出口端不能裝錯，泵效套也不能互換。高速機械密封當線速度超過25~30m/s時，可視為高速。SLJY40-200泵用機械密封北京脫硫泵用機械密封型號。</p><div

機械密封概述機械密封是一種用來解決旋轉軸與機體之間密封的裝置，主要依靠彈性元件對動、靜環(huán)端面密封副的預緊和介質壓力與彈性元件壓力的壓緊而實現(xiàn)密封的，又叫做端面機械密封或端面密封。機械密封的安裝與維護1、機械密封的評價指標：泄漏量和使用壽命；2、影響機械密封指標的五個環(huán)節(jié)：1）選項、2）制造、3）安裝、4）使用、5）維護一般來講，機械密封的選項和制造這兩個環(huán)節(jié)由制造廠完成，原則上基本沒問題，而安裝、使用及維護這三個環(huán)節(jié)是由用戶來完成的。依據(jù)機械密封失效原因的分析，排在首位的不是密封本身的問題，很大程度取決于密封的安裝、使用及維護方面的原因。應充分認識機封在安裝、使用及維護方面的重要性。相關領域資料內容涉及的面很廣，具體來說內容涵蓋傳統(tǒng)機械行業(yè)、機械加工、制造技術、材料類、材料成型、電氣行業(yè)、液壓行業(yè)、機電類、機械傳動、一千多份非標設備三維模型和非標設計等等領域。</p><p> 有的密封公司把滑動面速度高達33m/s，才作為高速機械密封.’我國ZBJ22-001-88規(guī)定密封端面平均線速度為25~100m/s時為高速機械密封，密封端面平均線速度大于100m/S時為超高速機械密封.在高速時，由于離心力的影響，造成振動和不平衡度，高速如同高壓一樣，產(chǎn)生熱變形、熱應力裂紋及磨損物、沉淀物引起泄漏損失，而且這種損失將隨滑動速度的增加而強烈地增加.一、高速機械密封的要求1.減少轉動件的重量(質量)，提高動力平衡度高速時，離心力的影響使彈簧扭曲和偏離銷孔中心，因此，彈簧必須是靜止式。這樣減少了轉動件的重量及由此造成的不平衡度。2.及時排除摩擦熱加大冷卻介質的流量，高速泵為10~20L/min，有的高速密封的沖洗量達50~100L/min。用油作阻封液時，為了使氣體的溶解度和結焦盡量小，應選用粘度低的油。如摩擦副處于高溫條件下工作時，要盡一切可能使密封液在蒸發(fā)時不留殘渣，所以使用聚乙二醇這類合成介質作阻封液，3.及時檢查滑動端面磨損量當端面磨損量達到，就要對端面進行研磨，并重新檢查端面粗糙度和平直度。二、9AB型高速泵機械密封。用于壓縮機的高速機械密封的直徑較大。天津格蘭富泵用機械密封型號。</p><div

而用于高速泵的機械密封尺寸一般都在2in左右.高速泵用的機械密封以美國約翰克蘭公司(JohnCranePackingCompany)的9AB型密封**為典型[圖10-17(a),(b)]，這種密封常用在美國Sundstrand公司高速泵的齒輪箱和泵體的密封上.為了節(jié)省空間并獲得較高的重量與功率比，無論泵的結構和機械密封結構都很緊湊，一般石油化工公司都引進這種高速泵‘，目前揚子石油化工公司有關裝置使用51臺(見表3-41)，中國石油化工總公司系統(tǒng)使用近200臺。圖中60C用于齒輪箱密封，60A或60A+60B用于泵葉輪端密封.低溫機械密封一般低溫機械密封是指工作溫度在0~-50℃的密封，API-610的低溫含義指溫度低于-29℃，國內通常以密封腔溫度低于-20℃為低溫.實際上，低溫范圍較寬，可以劃分為:低溫:-20~-50℃中低溫:-50~-100℃極低溫:-100~-196℃超低溫:<-196℃泵送低溫介質主要指液化氣體和易揮發(fā)的液體，如液態(tài)氮、液態(tài)氧、甲烷、乙烷、乙烯等液化氣。關于氮、氧、空氣等液化氣體的物理性能如表10-3所示.關于乙烯、丙烯、甲烷、乙烷、丙烷的物理性能如圖10-18(a)、(b)、(c)、(d)所示·一、低溫機械密封的要求1.材料要求金屬材料隨著溫度降低。河北渣漿泵用機械密封型號。SLJY40-200泵用機械密封</p><p

接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導致軸間泄漏。鎖母鎖緊過度只會導致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運轉中鎖母會自動適時鎖緊，使軸間始終處于良好的密封狀態(tài)。、新的比舊的好相對而言，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；在聚合性和滲透性介質中，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。、拆修總比不拆好一旦出現(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(jīng)驗提高檢修質量。5、結束語以上總結了機械密封比較常見的滲漏原因和維護時的幾個常見的誤區(qū)。只有充分了解機械密封的結構和常見的一些泄漏現(xiàn)象，正確的分析導致各種泄漏的原因，才能對癥下藥進行治理，才能保證安全生產(chǎn)。SLJY40-200泵用機械密封</p><p
