羅茨風機械密封拆前需做的準備：1.檢查機械密封的型號、規(guī)格是否符合設計圖紙的要求，所有零件(特別是密封面、輔助密封圈)有無損壞、變形及裂紋等現象，若有缺陷，要更換或修復。2.檢查機械密封各零件的配合尺寸、粗糙度和平行度是否符合設計要求。3.羅茨風機使用小彈簧機械密封時，應檢查小彈簧的長短和剛性是否相同。4.檢查主機的竄動量、擺動量和撓度是否符合技術要求，密封腔是否符合安裝尺寸，密封端蓋與軸是否垂直一般要求為：軸竄動量不大于等于、旋轉環(huán)密封圈處的軸擺動量不大于、軸較大撓度不大于、密封端蓋與墊片接觸平面對中間線的不垂直度允許差為。5.羅茨風機應保持清潔，特別是旋轉環(huán)、靜止環(huán)密封面和.輔助密封圈表面應無雜質，勿用不清潔的布擦拭密封面。6.不允許用工具敲打密封元件，以防密封件被損壞。</p><p> 沖洗的方式主要有如下：（一）內沖洗1、正沖洗1）特點：利用工作主機的被密封介質，由泵的出口端通過管路引入密封腔。2）應用：用于清潔流體，p1稍大于p進，當溫度高或有雜質時，可在管路上設置冷卻器、過濾器等。2、反沖洗1）特點：利用工作主機的被密封介質，由泵的出口端引入密封腔，沖洗后通過管路流回泵入口。2）應用：用于清潔流體，且p進出，當溫度高或有雜質時，可在管路上設置冷卻器、過濾器等。3、全沖洗1）特點：利用工作主機的被密封介質，由泵的出口端通過管路引入密封腔，沖洗后再經管路流回泵入口。（二）外沖洗特點：引入外系統(tǒng)與被密封介質相容的清潔流體至密封腔進行沖洗。應用：外沖洗液壓力應比被密封介質大，適用于介質為高溫或固體顆粒的場合。沖洗液的流量應保證帶走熱量，還需滿足沖洗的需要，不會產生對密封件的沖蝕。為此，需控制密封腔的壓力和沖洗的流速，一般清潔沖洗液的流速應小于5m/s；含有顆粒的漿狀液體須小于3m/s，為達到上述的流速值，沖洗液與密封腔壓力的差值應<，一般取，對雙端面機械密封可取，沖洗液進入和排出密封腔的孔口位置，應設置在密封端面附近，且應在靠近動環(huán)側，為了防止石墨環(huán)被沖蝕或因冷卻不均引起溫差變形。高新區(qū)輕型機械密封件。</p><div

氟橡膠具有耐高溫、耐油、耐化學腐蝕的優(yōu)點。氟橡膠中應用廣的是含氟烯烴共聚物，主要是26型和23型。26型中有氟橡膠-26系偏氟橡乙烯與六氟丙烯的乳液共聚物和氟橡膠-246系偏氟乙烯、六氟丙烯與四氟丙烯的三元共聚物。23型氟橡膠由偏氟乙烯與三氟氯乙烯在室溫及。它不能用于液氨、氨水中。硅橡膠是由二甲基硅氧烷與其他有機硅單體在酸或堿性催化劑存在下聚合成的一種極性高分子聚合物。硅橡膠有很高的熱穩(wěn)定性，但它有極性，容易在酸堿作用下發(fā)生離子型裂解，因此耐腐蝕性差，不適宜用于石油系溶劑（如苯、甲苯等）、丙酮、酮醚等有機溶劑。聚四氟乙烯具有優(yōu)異的化學穩(wěn)定性和耐油、耐溶劑、抗老化、耐溫性能，并有相當低的摩擦因數和一定的強度、彈性、柔性和不粘著性，因此***用作各種溫度、壓力、腐蝕性介質條件下的密封圈。綜上所述，輔助密封材料，在一般介質中可使用橡膠材料制成的O形圈、墊圈和波紋管等；在腐蝕性介質中可使用聚四氟乙烯制成的V形圈、楔形環(huán)、墊圈和波紋管等；在高、低溫條件下可使用金屬波紋管。選用時應考慮材料的使用溫度和耐腐蝕性。機械密封輔助密封材料列表機械密封主要零件材料選擇機械密封各主要零件的材料應根據使用工況進行選擇，見下表。蘇州109-25機械密封件。福建機械密封件銷售</p><p

2.故障二：真空狀態(tài)運行造成的機械密封滲漏產生原因：泵在起動、停機過程中,由于泵進口堵塞，抽送介質中含有氣體等原因，有可能使密封腔出現負壓，密封腔內若是負壓，會引起密封端面干摩擦，內裝式機械密封會產生漏氣(水)現象。解決方法：裝配采用雙端面機械密封，這樣有助于改善潤滑條件，提高密封性能。（二）由于介質引起的滲漏1.故障一：靜環(huán)和動環(huán)的輔助密封件無彈性或者有的已經腐爛，造成了機封的大量滲漏甚至有磨軸的現象。產生原因：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,當污水為酸性堿性時易腐蝕。解決方法：對腐蝕性介質,橡膠件應選用耐高溫、耐弱酸、弱堿的氟橡膠。2.故障二：真空固體顆粒雜質引起的機械密封滲漏產生原因：固體顆粒進入密封端面,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)不能補償磨耗位移,硬對硬摩擦副的運轉壽命要比硬對石墨摩擦副的長,因為固體顆粒會嵌入石墨密封環(huán)的密封面內。解決方法：在固體顆粒容易進入的位置應選用碳化鎢對碳化鎢摩擦副的機械密封。順平化工機械密封件廠</p><p
