加熱圈的可靠性與壽命-上海雄雷環?？萍加邢薰?/title> <meta name="keywords" content="電加熱圈" /> <meta name="description" content="電加熱圈的可靠性與管芯類型有很大關系，例如用金屬網卷成網管做干線的管芯由于存在自充滿問題，以及對不凝氣體的存在非常敏感，因而其可靠性較差。相比之下，軸向槽道加熱圈就要可靠得多?？煽啃赃€包括性能的可預見性及復現性。多層網管芯在這方面就較..." /> <link rel="stylesheet" type="text/css"

16px;">電加熱圈的可靠性與管芯類型有很大關系，例如用金屬網卷成網管做干線的管芯由于存在自充滿問題，以及對不凝氣體的存在非常敏感，因而其可靠性較差。相比之下，軸向槽道加熱圈就要可靠得多?？煽啃?還包括性能的可預見性及復現性。多層網管芯在這方面就較差。它的溫差與網層之間的貼緊程度有極大關系，在工藝上很難保證一致。而采用燒結工藝的管芯(燒結粉末、網、纖維等)，性能復現性就較好。</span></p><p style="text-indent: 2em; line-height: 2em;"><span style="font-size: 16px;">加熱圈的壽命主要取決于所選材料與工質的相容性?？梢哉f相容性是保證加熱圈能長期工作的關鍵，必須引起加熱圈設計者的高度重視。影響加熱圈壽命的另一個因素是工質泄漏量，由于加熱圈中工質的數量一般是很少的，因此在長期間內即便是很刁喲泄漏也會使加熱圈失效，因此需對管壁材料的焊接性能、焊接方法、檢漏方法加以仔細考慮。</span></p><p><br/></p></div> <h3
