從而阻止密封液的泄漏。其密封能力的大小與螺旋角度、螺距、齒寬、齒高、齒的作用長(zhǎng)度以及軸與套之間的間隙大小有關(guān)。由于密封之間不發(fā)生磨擦，因而壽命長(zhǎng)，但由于結(jié)構(gòu)空間的限制，其螺旋長(zhǎng)度一般較短，因而其密封能力也受到局限。在泵降速使用時(shí)，其密封效果則會(huì)大打折扣。干氣密封干氣密封即“干運(yùn)轉(zhuǎn)氣體密封”是將開槽密封技術(shù)用于氣體密封的一種新型軸端密封，屬于非接觸密封。特點(diǎn)：密封性能好，壽命長(zhǎng)，不需密封油系統(tǒng)，功率消耗少，操作簡(jiǎn)單及運(yùn)行維護(hù)費(fèi)用低。干氣密封作為不需任何密封端面冷卻和潤(rùn)滑用油的無維修密封系統(tǒng)，正取代浮環(huán)密封和迷宮密封而成為石化行業(yè)高速離心壓縮機(jī)軸封的主體密封。適用場(chǎng)合：離心式壓縮機(jī)等高速等高速流體機(jī)械，適用于少量工藝氣泄漏到大氣中無危害的工況，如空壓機(jī)，氮壓機(jī)等。油封密封油封密封是一種自緊式唇狀密封，其結(jié)構(gòu)簡(jiǎn)單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對(duì)磨損有一定的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場(chǎng)合的化工泵上。迷宮密封迷宮密封是在轉(zhuǎn)軸周圍設(shè)若干個(gè)依次排列的環(huán)行密封齒，齒與齒之間形成一系列截流間隙與膨脹空腔。蘇州109-50機(jī)械密封件件蘇州YM109機(jī)械密封件。</p><div

防止將工具、多余零件密封在箱殼之中造成事故。（三）裝配工作中的密封性在機(jī)械使用中，由于密封失效，常常出現(xiàn)"三漏"（漏油、漏水、漏氣）現(xiàn)象。這種現(xiàn)象輕則造成能量損失，以至降低或喪失工作能力，造成環(huán)境污染，重則可能造成嚴(yán)重事故。因此，防止"三漏"極為重要。流體漏損的原因可能由于密封裝置的裝配工藝不符合要求，也可能是由于密封件被磨損、變形、老化、腐蝕所至，而后者也往往與裝配因素（包括選用密封件材料、預(yù)緊程度、裝配位置等）有關(guān)。為此，在裝配工作中必須給以足夠的重視。1、選用密封材料要恰當(dāng)一般要根據(jù)不同的壓力、溫度、介質(zhì)選用。紙質(zhì)墊片只用于低壓、低溫條件；橡膠耐壓、耐溫能力也不高，且要考慮各種橡膠的不同性能，如耐油、耐酸、耐堿等；塑料的耐壓能力較好，但也不耐高溫；石棉強(qiáng)度較低，卻能耐高溫；金屬則兼有耐高溫、高壓的能力。2、合理裝配.要有合適的裝配緊度，并且壓緊要均勻。當(dāng)壓緊度不足時(shí)，會(huì)引起泄漏，或者在工作一段時(shí)間后，由于振動(dòng)及緊定螺釘被拉長(zhǎng)而喪失緊度，導(dǎo)致泄漏；壓緊度過緊，對(duì)靜密封的墊片來講，會(huì)喪失彈力，引起墊片早期失效；對(duì)動(dòng)密封來講，會(huì)引起發(fā)熱、加速磨損、增大摩擦功率等不良后果。張家口波紋管機(jī)械密封件</p></p><br
