對于離心泵，轉(zhuǎn)速在2950r／min和直徑小時，可忽略離心力的影響；當直徑較大時，環(huán)座產(chǎn)生的離心力較大，會抵消一部分過盈值，不容忽略。此外，環(huán)座材料的彈性模量不同，采用的過盈值也不同，對于彈性錯量小的材料（如4J42和鈦合金等），過盈值可相應大些。我們引用計算過盈值的公式e=dm（a2一a1）（t—t0），取e=0．002dm有0．002=（a2一a1）（t—t0）可得**高使用溫度t=（a2一a1）+t0對于3Cr13、1Cr18Ni9Ti、Icr18Ni12Mo2Ti和哈氏合金B(yǎng)與C，其彈性模量相近，當它們與YG6和YGS熱裝時，**高使用溫度見表2(取t。＝22℃)?？紤]離心力的影響和高溫下環(huán)座材料的應力松弛后，各種環(huán)座材料的允許使用溫度見圖28，超出此溫度在密封腔中就應采取措施，降低溫度。八、輔助密封圈種類動環(huán)和軸（軸套）以及靜環(huán)和壓蓋之間的密封靠輔助密封圈來實現(xiàn)。它們基本上屬于靜密封，當密封端面和軸中心線不垂直時，動環(huán)密封圈沿軸向有很小的軸向運動，其位移量取決于密封端面和軸中心的垂直度誤差、運動的次數(shù)和軸轉(zhuǎn)速等。輔助密封圈的種類很多，從材料角度分類有合成橡膠、聚四氟乙烯和柔性石墨等；從斷面形狀分類有圓形、方形、V形、楔形及包覆形密封圈。臨沭耐弛泵用機械密封山西脫硫泵用機械密封型號。</p><div

硬環(huán)的材質(zhì)種類很多（見“27”）。只有在特殊情況下，如介質(zhì)中含有固體顆粒、有結(jié)晶析出或高粘度流體中才選用硬對硬的配對。當選用一軟一硬的配對時硬環(huán)端面的寬度比軟環(huán)寬，在硬對硬的材質(zhì)中可不受此限制。為減少泄漏量和機械雜質(zhì)進入密封端面的可能性，盡量采用內(nèi)裝內(nèi)流式密封結(jié)構(gòu)S選擇導熱性良好的材料做動環(huán)，以散出較多的熱量，降低密封端面的溫度。為保證密封環(huán)的整體強度和剛度，環(huán)的壁厚不可太薄。對于導熱性良好的材料，增加環(huán)厚有利散熱；對于導熱性欠佳的材料厚度可小些。對于所受壓力較高的密封環(huán)，要從力學角度另行設計，必要時采取加固措施。環(huán)的形狀要軸對稱，以減少其不對稱的機械變形和熱變形。動環(huán)做補償環(huán)時，例如國產(chǎn)104和B104型密封（圖13、圖14），動環(huán)和軸（軸套）的（直徑）間隙為0．40～0．60mm，以防止動環(huán)在工作中卡住而失去補償能力；靜環(huán)內(nèi)徑要比軸（軸套）大l～2mm，避免兩者摩擦。密封端面的寬度是個重要參數(shù)，要綜合考慮。三、密封端面的寬度要考慮的因素密封端面的寬度一般是首先決定軟面的寬度，硬面寬度自不待說。泄漏量與端面寬度關系不大。但是，從產(chǎn)生的摩擦熱量來說窄一些較好，產(chǎn)生的熱量較少，溫度梯度小，熱變形也小。</p><p>

九、波紋管式機械密封波紋管式機械密封的應用范圍很廣，從低溫到高溫，從中性介質(zhì)到腐蝕性介質(zhì)，從低速到高速，從普通到苛刻的工作條件都可選用。所有這些可通過變更波紋管的幾何形狀（如內(nèi)外徑、波片厚度和波數(shù)等）與材料彈性模量，改變波紋管的彈率。根據(jù)介質(zhì)的腐蝕性能，選用不同的波紋管材料等。例如對工作壓力和溫度都不高的中性介質(zhì)（油和水等），可選用橡膠制造的簡易波紋管密封；在腐蝕性介質(zhì)中（酸或減等），可選用四氟制造的波紋管密封；高溫和高速下，可采用焊接金屬波紋管機械密封等。焊接金屬波紋管密封的特點焊接金屬波紋管機械密封用的波紋管是由軋制的金屬薄板沖裁成環(huán)形波紋狀的型面，波形多采用S形，將許多個波片重疊起來，分別在環(huán)形的外緣和內(nèi)緣進行焊接，組成一個波紋管，兩端再與傳動座和動環(huán)焊接成整體。除了不用輔助密封圈外，還具備使用溫度范圍***的特點，**高可達600度，**低可到一200度。此外高速下對軸的振動和振擺適應性較強，有很好的補償能力，保證密封端面良好地貼合。但是長期在高溫下工作的焊接金屬波紋管密封，波紋管的彈率有減小的趨勢（俗稱“失彈”），使用受到一定的限制。遵義化工泵用機械密封廠家。臨沭耐弛泵用機械密封</p><p

由介質(zhì)壓力變化引起端面比壓的增量大于或等于介質(zhì)壓力的增量。平衡型：載荷系數(shù)K<1的密封，也就是由介質(zhì)壓力變化引起的端面比壓的增量小于介質(zhì)壓力的增量，稱為平衡型密封。根據(jù)密封端面的數(shù)量和布置方式可分為單端面、雙端面及多端面機械密封。兩組密封端面“背靠背”（圖10a）或“面對面”（圖10b）布置的密封叫雙端面機械密封。對于工作介質(zhì)有毒、易爆、易燃、易揮發(fā)、易結(jié)晶、高溫、低溫或工作介質(zhì)是氣體，或?qū)τ诟哒婵斩鹊拿芊?，可用雙端面密封。此時雙端面之間的密封腔引入封液進行堵封、潤滑和冷卻。一般情況下封液選用潔凈和潤滑性好的介質(zhì)。二、串聯(lián)機械密封應用的工況兩組或兩組以上同向布置的單端面機械密封組成串聯(lián)機械密封（圖11）。這種密封方式使密封腔的壓力逐級降低，介質(zhì)不至外漏。串聯(lián)密封一般情況下很少采用，只有在壓力很高時采用。補償機構(gòu)為波紋管，密封環(huán)（動環(huán)或靜環(huán)）和波紋管制成一個整體，中間沒有輔助密封圈（見圖8）稱為波紋音式機械密封。波紋音式機械密封減少了一個泄漏點；同時減少了補償機構(gòu)的摩擦阻力，改善了追隨性；對于焊接金屬波紋管密封（圖8b）使用溫度不受輔助密封圈的限制；對于四氟波紋管密封（圖8a）可用于腐蝕性介質(zhì)中。廣東泥漿泵用機械密封</p><p
