焊接金屬波紋管的彈率的計(jì)算由于焊接金屬波紋管機(jī)械密封不用彈簧，彈性力完全由波紋管產(chǎn)生，因此波紋管設(shè)計(jì)時(shí)要考慮其彈率。一般將波紋管的彈率設(shè)計(jì)得小些，當(dāng)要求一定的彈力時(shí)，波紋管的壓縮量就要適當(dāng)?shù)丶哟?。運(yùn)轉(zhuǎn)相當(dāng)長(zhǎng)時(shí)間后，如果密封端面磨損，波紋管自動(dòng)補(bǔ)償，而彈力降低不會(huì)大，始終保持密封端面有足夠的壓比。為保證足夠的彈性力，壓縮量在10mm左右，低不能低于6mm。工作時(shí)每個(gè)波的變形以小為宜，為保證一定的壓縮量，要適當(dāng)增加波數(shù)，保持波距。一般波數(shù)取16～20，溫度和壓力高時(shí)波數(shù)宜取多。波紋管的彈率是幾何形狀和材料的函數(shù)，常用下式計(jì)算：k=πEt3(c)d2/2nB3d1式中k——波紋管彈率，N／mm；E——材料在工作溫度下的彈性模量，N/mm2；t——波片厚度，mmn——波紋管波數(shù)；d1、d2——分別為波紋管的內(nèi)外徑，mm；B——波紋管的片寬，mm。B=（d2-d1）／2公式中沒有考慮波片的斷面形狀等因素，因此有一定的誤差。實(shí)際工作中可在彈簧測(cè)力計(jì)上測(cè)量其彈率。普通彈簧的彈率計(jì)算在一般“機(jī)械零件”書上能找到，故在此不作介紹。非對(duì)稱型波紋管焊接金屬波紋管機(jī)械密封以其結(jié)構(gòu)簡(jiǎn)單、伸縮性好和耐高溫等優(yōu)點(diǎn)，得到了日益廣的應(yīng)用，尤其是高溫泵的密封中。</p><p> 不僅在開啟力和閉合力之間有嚴(yán)格比率，而且要求整個(gè)密封結(jié)構(gòu)經(jīng)得住高壓而不變形，此外，還要維持穩(wěn)定的液膜以保證密封性能.一、高壓機(jī)械密封的要求1.增大密封零件截面對(duì)轉(zhuǎn)動(dòng)零件的截面要加大，靜環(huán)也相應(yīng)有較大的截面，不要在靜環(huán)外徑上有臺(tái)階或開槽.但要注意，隨著密封面寬度b的增加，熱變形和磨損也隨之增加，同樣要增加壓蓋的厚度以防變形和能承受壓力.使用重載荷彈簧，使用較大直徑的銷子以適應(yīng)較大的啟動(dòng)扭矩.2.提高密封零件的加工精度(1)壓蓋底部裝靜環(huán)的幢孔面要保證高的平直度，因?yàn)樵诟邏合?，任何表面上的高出點(diǎn)會(huì)傳給靜環(huán)而引起泄漏;(2)提高密封面內(nèi)外徑和寬度的加工精度，因?yàn)樵诟邏簳r(shí)，，密封內(nèi)外徑和寬度的精度對(duì)比壓的變化有明顯的影響.密封端面研磨、.拋光后的粗糙度為(▽12~▽13)，平直度必須限制在1個(gè)光帶以內(nèi).此外，摩擦端面的垂直度和軸的精度也要相應(yīng)提高.注意在高壓下因不同介質(zhì)所造成的沖刷腐蝕和磨損，圖10-12(a),(b)表示不同摩擦副材料在不同的轉(zhuǎn)速下介質(zhì)為烴和水及水溶液時(shí)壓力與密封尺寸的關(guān)系.5采用流體動(dòng)壓式機(jī)械密封流體動(dòng)壓式(也稱流體動(dòng)力式，熱流體動(dòng)壓式)機(jī)械密封是考慮在高壓和摩擦熱的情況下。湘潭204B釜用機(jī)械密封件。</p><div

這兩套密封與旋轉(zhuǎn)方向有關(guān)，進(jìn)出口端不能裝錯(cuò)，泵效套也不能互換。高速機(jī)械密封當(dāng)線速度超過25~30m/s時(shí)，可視為高速，有的密封公司把滑動(dòng)面速度高達(dá)33m/s，才作為高速機(jī)械密封.’我國(guó)ZBJ22-001-88規(guī)定密封端面平均線速度為25~100m/s時(shí)為高速機(jī)械密封，密封端面平均線速度大于100m/S時(shí)為超高速機(jī)械密封.在高速時(shí)，由于離心力的影響，造成振動(dòng)和不平衡度，高速如同高壓一樣，產(chǎn)生熱變形、熱應(yīng)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(dòng)速度的增加而強(qiáng)烈地增加.一、高速機(jī)械密封的要求1.減少轉(zhuǎn)動(dòng)件的重量(質(zhì)量)，提高動(dòng)力平衡度高速時(shí)，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(zhuǎn)動(dòng)件的重量及由此造成的不平衡度。2.及時(shí)排除摩擦熱加大冷卻介質(zhì)的流量，高速泵為10~20L/min，有的高速密封的沖洗量達(dá)50~100L/min。用油作阻封液時(shí)，為了使氣體的溶解度和結(jié)焦盡量小，應(yīng)選用粘度低的油。如摩擦副處于高溫條件下工作時(shí)，要盡一切可能使密封液在蒸發(fā)時(shí)不留殘?jiān)?，所以使用聚乙二醇這類合成介質(zhì)作阻封液，3.及時(shí)檢查滑動(dòng)端面磨損量當(dāng)端面磨損量達(dá)到，就要對(duì)端面進(jìn)行研磨，并重新檢查端面粗糙度和平直度。二、9AB型高速泵機(jī)械密封。薊州區(qū)207釜用機(jī)械密封廠家。南寧2007釜用機(jī)械密封</p><p
