也采用316型不銹鋼做彈簧材料.碟形彈簧用于乙醛裝置.這種短形結(jié)構(gòu)彈簧，使密封更加緊湊.碟形彈簧材料用HastelloyC4合金(相當(dāng)于DIN材料號)和GrNiMo不銹鋼材料.(5)波紋管材料有Inconel}鉻鎳鐵洽金、F聚四氟乙烯、氯磺化聚乙烯橡(Iiypalon)和丁睛橡膠.金屬波紋管采用焊接結(jié)構(gòu)，(6)V形密封圈采用聚四氟乙烯材料，典型牌號是泰弗隆(Teflon).O形密封圈采用丁睛橡膠(NBR)和氟橡膠(Viton}，有的密封公司為了提高耐蝕性能，建議用橡膠圈外包覆聚四氟乙烯的0形圈。有幾個密封公司推薦既具有橡膠彈性又具有聚四氟乙烯耐蝕性能的材料kalrez，它是美國杜邦公司新近推出的合成橡膠材料，已有Kalrez材料的0形圈系列產(chǎn)品.5公制密封件占大多數(shù)。從現(xiàn)有引進(jìn)的機(jī)械密封套數(shù)可以看出，英制密封只占8%左右。另外從英國克蘭密封公司的產(chǎn)品介紹中也可看出該公.司逐步向公制化過渡，有的產(chǎn)品則是公、英制同時生產(chǎn)。6.推行IS03069-74密封腔尺寸標(biāo)準(zhǔn)。自1974年國際標(biāo)準(zhǔn)化組織制訂IS03069密封腔尺寸的規(guī)定以來，各國密封公司相繼采用IS03069-74標(biāo)準(zhǔn)，幾個大的密封公司在產(chǎn)品樣本中幾乎都注明哪些品種適用于ISO-3069的尺寸系列.這些公司有:英國克蘭公司，日本比拉公司、日本Eagl。</p><p> 依靠介質(zhì)壓力和彈簧力使動靜環(huán)之間的密封端面緊密貼合，阻止了介質(zhì)的泄漏。摩擦副表面磨損后，在彈簧（5）的推動下實(shí)現(xiàn)補(bǔ)償。為了防止介質(zhì)通過動環(huán)與軸之間泄漏，裝有動環(huán)密封圈（3）；而靜環(huán)密封圈（7）則阻止了介質(zhì)沿靜環(huán)和壓蓋（8）之間的泄漏。長期的實(shí)踐證明，輔助設(shè)施的作用不可忽視。從國外進(jìn)來的泵，在提供的機(jī)械密封圖紙上，不僅有密封結(jié)構(gòu)圖，而且在這張圖上明確地畫出了輔助設(shè)施的安裝圖，并注明輔助設(shè)施的種類和數(shù)量。國內(nèi)的制造廠有的開始注意這個問題；有的還沒認(rèn)識，這是不應(yīng)該的。輔助設(shè)施不僅起冷卻和潤滑作用，還可改善密封的工作環(huán)境，從而減少泄漏量和延長使用壽命。因此有人把輔助設(shè)施看作是機(jī)械密封的組成部分。無疑，這一觀點(diǎn)將被越來越多的人接受。機(jī)械密封被***地應(yīng)用于各種旋轉(zhuǎn)機(jī)械的軸封，工況不同，使用的密封也不同。機(jī)械密封按使用條件可分為高速和普通機(jī)械密封；高壓和低壓機(jī)械密封；高溫、常溫和低溫機(jī)械密封；泵用、壓縮機(jī)用和釜用機(jī)械密封以及耐腐蝕機(jī)械密封和抗顆粒的機(jī)械密封等。通常都按機(jī)械密封的結(jié)構(gòu)和原理來分類，例如旋轉(zhuǎn)式和靜止式機(jī)械密封；內(nèi)流式和外流式機(jī)械密封；平衡型和非平衡型機(jī)械密封等。廈門MR-D釜用機(jī)械密封件。</p><div

當(dāng)產(chǎn)生抽空（汽蝕）時，靜環(huán)能離位，從而損壞密封。2）固定型靜環(huán)。圖21所示為幾種固定型靜環(huán)，這種靜環(huán)由于浮動性差，安裝時尤其要注意密封端面和軸心線的垂直度。其優(yōu)點(diǎn)是泵抽空時靜環(huán)不至于離位，較為可靠。3）粘結(jié)型靜環(huán)。上兩種靜環(huán)安裝在壓蓋中時都設(shè)有密封圈，而粘結(jié)型靜環(huán)則取消了密封圈，靜環(huán)與壓蓋之間的密封和防轉(zhuǎn)，用粘結(jié)劑實(shí)現(xiàn)。由于采用了粘結(jié)劑，使用溫度和介質(zhì)受到了粘結(jié)劑性能的限制，盡管如此，仍在很多場合得到應(yīng)用。集裝式密封的軸套的傳動普通機(jī)械密封的軸套都是事先安裝和固定在軸上后再安裝機(jī)械密封，而集裝式密封則不同，它是將密封軸套和壓蓋預(yù)先裝在軸套上，再整體向軸上安裝，于是存在一個軸套如何固定在軸上，并傳遞扭矩的問題，同時還要解決軸套和軸之間的泄漏問題。圖42a表示了一種傳動方式。螺釘安裝在零件A上，在軸套的對應(yīng)部位開有圓孔，將螺釘通過軸套的圓孔，并旋緊在軸上，即可實(shí)現(xiàn)軸套和軸的傳動。軸套和軸的密封，靠O形圈來完成。這種傳動方式比較簡單。圖42b是另一種傳動方式。它用圓螺母A壓緊軸和軸套之間的填料（四氟制成），靠填料與軸的摩擦力來傳動，同時也起到了密封圈的作用。安慶M481釜用機(jī)械密封件。漳州搪瓷釜用機(jī)械密封</p><p
