比YG6大1倍多，為／℃（10～500℃時(shí)）。這兩點(diǎn)決定了耐熱沖擊性能不如YG6好。正因?yàn)榫€膨脹系數(shù)較大，和馬氏體不銹鋼接近（10～500℃時(shí)為11X10-6／℃），南寧222型釜用機(jī)械密封，為和環(huán)座焊接提供了有利條件。焊接時(shí)需在環(huán)和座之間鋪放一層鎳基粉末，置于真空電阻爐中，經(jīng)1100℃高溫熔焊，然后進(jìn)行回火處理，以消除焊接應(yīng)力。由于是焊接的密封環(huán)，南寧222型釜用機(jī)械密封，硬質(zhì)合金環(huán)的厚度可以比YG6薄，毛坯的厚度也只有3～3．5mm。以因密度小，是YG6的一半（7~），因此，可節(jié)約貴重金屬，價(jià)格較低。這種合金的牌號(hào)為CN15，其中Cr3C285%，Ni為15%，由北京硬質(zhì)合金廠研制成功。熱裝式密封環(huán)以其性能***應(yīng)用，但過(guò)盈量過(guò)大則硬質(zhì)合金在較大擠壓應(yīng)力作用下產(chǎn)生變形；過(guò)盈量過(guò)小，南寧222型釜用機(jī)械密封，使用時(shí)會(huì)松脫。經(jīng)長(zhǎng)期觀察分析，熱裝式密封環(huán)松脫主要是由于環(huán)座和硬質(zhì)合金環(huán)兩者線膨脹純利系數(shù)的差別，工作出現(xiàn)間隙。由此可見(jiàn)，熱裝式密封環(huán)失效的根本原因主要有二：一是過(guò)盈值小，三是環(huán)座材料選擇不當(dāng)，線膨脹系數(shù)太大。確定過(guò)盈值應(yīng)遵循的原則：1）從傳遞扭矩的角度考慮過(guò)盈值應(yīng)足夠大。2）從環(huán)的變形的角度考慮過(guò)盈值不可過(guò)大。綜合起來(lái)，在滿足環(huán)和座傳遞扭矩的情況下，取小的過(guò)盈值。滄州FMY212釜用機(jī)械密封廠家。南寧222型釜用機(jī)械密封</p><div

九、波紋管式機(jī)械密封波紋管式機(jī)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(guò)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(duì)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(jiǎn)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(jī)械密封等。焊接金屬波紋管密封的特點(diǎn)焊接金屬波紋管機(jī)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(gè)波片重疊起來(lái)，分別在環(huán)形的外緣和內(nèi)緣進(jìn)行焊接，組成一個(gè)波紋管，兩端再與傳動(dòng)座和動(dòng)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(diǎn)，高可達(dá)600度，低可到一200度。此外高速下對(duì)軸的振動(dòng)和振擺適應(yīng)性較強(qiáng)，有很好的補(bǔ)償能力，保證密封端面良好地貼合。但是長(zhǎng)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(shì)（俗稱“失彈”），使用受到一定的限制。南寧222型釜用機(jī)械密封黃岡FMY212釜用機(jī)械密封件。</p><div

也稱平直度）是密封環(huán)很重要的一個(gè)質(zhì)量指標(biāo)，要求在0．0009mm以內(nèi)，這樣的數(shù)量級(jí)用普通的量具是無(wú)法測(cè)量的。既準(zhǔn)確又迅速的方法是用光干涉法。它需要一個(gè)光學(xué)平晶和單色光源，一般用鈉光燈。檢測(cè)時(shí)，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(zhǎng)為0．6μm，每個(gè)干涉條紋為半個(gè)波長(zhǎng)，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(xué)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(lái)檢驗(yàn)平面度，這說(shuō)明端面的內(nèi)緣高，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(guò)2個(gè)。六、動(dòng)環(huán)和靜環(huán)動(dòng)環(huán)可分為非補(bǔ)償型和補(bǔ)償型兩種。在靜止型機(jī)械密封中，采用非補(bǔ)償型動(dòng)環(huán)，固在軸上，有的用軸套壓緊在軸上（圖3）。補(bǔ)償型動(dòng)環(huán)***用于旋轉(zhuǎn)型機(jī)械密封中。</p><p>
