也稱平直度）是密封環(huán)很重要的一個質(zhì)量指標，要求在0．0009mm以內(nèi)，這樣的數(shù)量級用普通的量具是無法測量的，婁底襄陽五二五泵用機械密封件維修。既準確又迅速的方法是用光干涉法。它需要一個光學平晶和單色光源，一般用鈉光燈。檢測時，將平晶放到被檢的密封端面上，斜上方用鈉光燈照射（圖15）檢查干涉條紋的數(shù)量。鈉光的波長為0．6μm，每個干涉條紋為半個波長，即一條干涉條紋為0．3μm，由干涉條紋的數(shù)量即可確定密封端面的平面度。確定干涉條紋的數(shù)量：密封端面的平面度不同，條紋的種類也不同。圖16表示了幾種平面度合格的圖像，至于不合格的圖像各式各樣未予繪出。圖16a是平直的條紋，表明密封端面的平面度接近光學平晶的平面度，這種平面度高；圖16b是彎曲的條紋，干涉條紋數(shù)在一條以內(nèi)，即小于μm；圖16c也是彎曲的條紋，干涉條紋數(shù)二條，平面度在μm以內(nèi)；圖16d是同心圓狀的干涉條紋，如果是從平板研磨后取下來檢驗平面度，這說明端面的內(nèi)緣高，婁底襄陽五二五泵用機械密封件維修，外緣低，同心圓數(shù)量越多，其內(nèi)外緣高低差別越大。出面同心圓的條紋不要超過2個，婁底襄陽五二五泵用機械密封件維修。六、動環(huán)和靜環(huán)動環(huán)可分為非補償型和補償型兩種。在靜止型機械密封中，采用非補償型動環(huán)，固在軸上，有的用軸套壓緊在軸上（圖3）。補償型動環(huán)***用于旋轉(zhuǎn)型機械密封中。銅川石家莊工業(yè)泵泵用機械密封件大全。婁底襄陽五二五泵用機械密封件維修</p><div

九、波紋管式機械密封波紋管式機械密封的應(yīng)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廣的特點，可達600度，可到一200度。此外高速下對軸的振動和振擺適應(yīng)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。焊接金屬波紋管的彈率的計算由于焊接金屬波紋管機械密封不用彈簧。婁底襄陽五二五泵用機械密封件維修婁底襄陽五二五泵用機械密封件維修。</p><div

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(yīng)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℃)。考慮離心力的影響和高溫下環(huán)座材料的應(yīng)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(yīng)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。</p><p>

石油化工流程泵大都選用內(nèi)流型機械密封，只有在壓力和溫度不高的腐蝕性介質(zhì)中才選用外流型機械密封。按補償機構(gòu)中彈簧的數(shù)量可分為多彈簧和單彈簧機械密封。補償機構(gòu)中有多個彈簧的密封稱為多彈簧機械密封（圖5）；補償機構(gòu)中只有一個彈簧的機械密封稱為單彈簧機械密封（圖6），多彈簧機械密封又稱小彈簧機械密封，這種結(jié)構(gòu)軸向尺寸較小，可用改變彈簧數(shù)量的方法改變彈性力，軸向力較均勻，適用于高速機械密封，在腐蝕性介質(zhì)中不宜采用。單彈簧機械密封又稱大彈簧機械密封，密封結(jié)構(gòu)較為簡單。有的密封型式還用彈簧傳遞扭矩。國產(chǎn)密封應(yīng)用大彈簧較多，但不能用于高速。圖5多彈簧機械密封圖6單彈簧機械密封補償機構(gòu)的作用是使密封端面緊密貼合，為達到此目的，采用的方法有兩種，一是彈性力，二是磁力。只有在系統(tǒng)內(nèi)壓力較低時采用磁力機械密封（圖7），大多數(shù)都用前者。除了用彈簧形成彈性力外還有用波紋管的，稱為波紋管式機械密封。波紋管的材料可用橡膠、聚四氟乙烯和焊接的金屬薄片（圖8）等。（圖8）根據(jù)密封面上介質(zhì)載荷的作用情況可分為平衡型和非平衡型密封（圖9）。非平衡型：載荷系數(shù)k≥1的密封稱為非平衡型密封，換言之。婁底襄陽五二五泵用機械密封件維修</p></p><br
