彈性力完全由波紋管產(chǎn)生，因此波紋管設(shè)計時要考慮其彈率。一般將波紋管的彈率設(shè)計得小些，當要求一定的彈力時，波紋管的壓縮量就要適當?shù)丶哟?。運轉(zhuǎn)相當長時間后，如果密封端面磨損，波紋管自動補償，而彈力降低不會大，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，不能低于6mm。工作時每個波的變形以小為宜，為保證一定的壓縮量，要適當增加波數(shù)，保持波距。一般波數(shù)取16～20，溫度和壓力高時波數(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，鞍山螺桿泵用機械密封件，N/mm2；t——波片厚度，鞍山螺桿泵用機械密封件，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，鞍山螺桿泵用機械密封件。實際工作中可在彈簧測力計上測量其彈率。普通彈簧的彈率計算在一般“機械零件”書上能找到，故在此不作介紹。非對稱型波紋管焊接金屬波紋管機械密封以其結(jié)構(gòu)簡單、伸縮性好和耐高溫等優(yōu)點，得到了日益廣的應(yīng)用，尤其是高溫泵的密封中，在有的國家已成為主要的軸封方式。國內(nèi)的焊接金屬波紋管密封質(zhì)量不夠穩(wěn)定。麗江凝結(jié)水泵泵用機械密封件大全。鞍山螺桿泵用機械密封件</p><div

圖3-22)Y4D型金屬波紋管密封是Eagle公司用于低壓(()，溫度-200~+400℃密封。波紋管采用Inconel718材料，這種合金的耐氧化性能可達980℃，在-196℃的低溫下屈服強度可達1426N/mm2.因此，Inconel718在高低溫條件下都適用.尤里卡裝置中凡高溫的減壓渣油，KSK油，輕、重瓦斯油的密封都采用Y4D型金屬波紋管機械密封.(圖3-10)雖然59B型密封的使用溫度范圍為-50~十230℃，如果泵送介質(zhì)借助于輸送裝置，通過冷卻器再進人密封，則59B型密封仍可用于介質(zhì)溫度大于230℃的場合.例如，芳烴裝置釜液泵GA-116AB的介質(zhì)溫度為290℃，就是采用外冷卻的59B型密封.4.上海水泵廠605系列波紋管機械密封介紹上海水泵廠引進美國EG&GSEALOL公司技術(shù)，已生產(chǎn)多種系列的密封，其中605系列是焊接波紋管機械密封，它的型號、規(guī)格和使用性能如表10-2所示.高壓機械密封通常認為，當機械密封的工作壓力超過4~5MPa時就視作高壓，有的密封公司把工作壓力達到3MPa就作為高壓;有的公司以PV值大小來衡量;有的公司則將壓力和溫度一起考慮.一般認為在高壓下，由于機械和熱變形危害機械密封的功能和可靠性，壓力越高，危害性越大.所以，用于極高壓力的密封比標準型密封要求設(shè)計改進。鞍山螺桿泵用機械密封件銅川石家莊工業(yè)泵泵用機械密封件廠家。</p><div

特種機械密封是指介質(zhì)、壓力、速度、溫度、結(jié)構(gòu)和用途方面與普通機械密封有所區(qū)別的機械密封，國內(nèi)也稱高參數(shù)機械密封.將機械密封分為普通和特種兩類，是便于說明機械密封的結(jié)構(gòu)、工作條件和使用要求，因此，有的密封廠商除列舉正常密封產(chǎn)品外，也列出高載荷機械密封;有的廠商則將產(chǎn)品樣本以外的機械密封稱作特種機械密封;有的廠商將高溫、高壓、高速的機械密封分別列出或加上標志，以便與普通機械密封產(chǎn)品相區(qū)別;有的廠商則以使用溫度來區(qū)分普通機械密封與特種機械密封.例如，英國克蘭公司將溫度一20~+230℃作為正常產(chǎn)品，超出以上溫度范圍的機械密封，就作為特種機械密封產(chǎn)品來考慮.本章所列的特種機械密封*指釜用、高溫、高壓、高速、低溫、真空和強腐蝕介質(zhì)以及帶磨料介質(zhì)的機械密封，對于那些用于宇航、核電，不在本章內(nèi)容之列。釜用機械密封釜用機械密封是指攪拌器(混合器)密封.從引進裝置中使用攪拌器的情況來看，凡大型釜用攪拌器都采用機械密封，它占攪拌器總量的，而未采用機械密封的攪拌器多數(shù)為小功率和堆、槽內(nèi)的小型攪拌器.近年來，機械密封在攪拌器上得到廣應(yīng)用，一是因為攪拌器軸的擺動量大，有的攪拌軸長達7~8m，雖然有底部支承裝置，但擺動量仍然很大。寶雞宙斯泵用機械密封件大全。鞍山螺桿泵用機械密封件</p><p

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機械密封傳動座和動環(huán)的傳動方式1）銷釘傳動。通過推環(huán)，在推環(huán)和動環(huán)之間用銷釘實現(xiàn)傳動（圖35），這種傳動方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動環(huán)外緣制成圓弧槽，而將與此接觸的傳動座壓成突耳，使之嵌入動環(huán)的槽中，實現(xiàn)傳動（圖13）。這種結(jié)構(gòu)可用于大彈簧，也可用于小彈簧的密封結(jié)構(gòu)。3）并圈彈簧傳動。傳動座與彈簧以及彈簧和動環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實現(xiàn)傳動（圖34），當然也有旋向的要求。這種結(jié)構(gòu)都用在大彈簧的密封結(jié)構(gòu)上。4）勾圈彈簧傳動。為了增加并圈彈簧傳動的可靠性，彈簧的兩個端頭制成彎勾形，分別鉤住傳動座和動環(huán)（圖36）。5）離合器傳動。傳動座和動環(huán)（或通過推環(huán)）分別制成方形的凸起和缺口，組裝好后凸起插入缺口中實現(xiàn)傳動（圖37）。6）波紋管傳動。這種方式是波紋管型密封的特有結(jié)構(gòu)，波紋管兩端分別與傳動座和動環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對金屬波紋管，則采用焊接；對于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機械密封的動環(huán)的旋轉(zhuǎn)靜止式機械密封的動環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。鞍山螺桿泵用機械密封件</p></p><br
