填料密封主要用于機械行業(yè)中的過程機器和設(shè)備運動部分的動密封，比如離心泵、壓縮機、真空泵、攪拌機、反應(yīng)釜的轉(zhuǎn)軸密封和往復(fù)泵、往復(fù)式壓縮機的柱塞或活塞桿，以及做直線、螺旋運動閥門的閥桿與固定機體之間的密封。填料函的基本形式是：(1)石棉盤根：耐溫和耐腐蝕性能都很好，但單獨使用時，密封效果不佳，所以總是浸漬或附加其他材料。油浸石棉盤根：它的基本結(jié)構(gòu)形式有兩種，一種是扭制，另一種是編結(jié)。又可分圓形和方形。(2)聚四氟乙烯編織盤根：將聚四氟乙烯細(xì)帶編織為盤根，有極好的耐腐蝕性能，又可用于深冷介質(zhì)。(3)橡膠O形圈：在低壓狀態(tài)下，密封效果良好。使用溫度受限制，如天然橡膠只能用于60℃。(4)塑料成型填料：一般做成三件式，臺州輕型機械密封廠家批發(fā)價格，也可做成其他形狀。所用塑料以聚四氟乙烯為多，也有采用尼龍66和尼龍1010的。(5)軟填料密封，又稱泥狀填料，是由新一代高性能合成纖維配以特殊的阻隔劑和潤滑劑精制而成的高級“盤根”。軟填料的任意尺寸，任意形狀，臺州輕型機械密封廠家批發(fā)價格，臺州輕型機械密封廠家批發(fā)價格，極易安裝，通過**的高壓便可直接注射，不必象傳統(tǒng)的盤根，需要預(yù)切割，能適用任何尺寸的填料腔密封軟填料密封適用范圍較大范圍，如高壓往復(fù)泵或低轉(zhuǎn)速泵、高溫閥桿、閥或填料盒的密封它結(jié)構(gòu)簡單。

style="font-size:12px;">對于反應(yīng)釜來說，通常在封頭法蘭與筒體的法蘭、接管法蘭、人孔、手孔、溫度計接管、視鏡、壓力表接管等部位泄漏點采用靜密封，因為密封面是相對靜止的。靜密封比較好解決，一般采用各種形式的靜密封墊片。</span> </p> <p> <span style="font-size:12px;">攪拌軸與釜體之間間隙處的泄漏點，由于旋轉(zhuǎn)的攪拌軸與靜止的釜體（上封頭）存在相對運動，要防止介質(zhì)的泄漏必須采用動密封裝置：機械密封與填料密封。</span> </p> <p> <span style="font-size:12px;">填料密封：結(jié)構(gòu)簡單、填料裝拆方便，但由于填料密封存在一些致命的弱點，導(dǎo)致它使用壽命較短，在高參數(shù)工況條件下（高溫、高壓、高轉(zhuǎn)速、高真空等條件）不適用。</span> </p> <p> <span style="font-size:12px;">機械密封：機械密封在反應(yīng)釜上多次采用，可以針對反應(yīng)釜的具體工況，對釜用機械密封進(jìn)行專門的結(jié)構(gòu)設(shè)計、材料選擇、潤滑冷卻措施考慮，以滿足工藝要求。</span> </p> <p> <br /> </p><div style="width:100%;text-align:

機械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機械密封，耐高壓、耐腐蝕機械密封，耐顆粒介質(zhì)機械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機械密封。 </p> <p> 選型的主要參數(shù)有：密封腔體壓力(MPA)、流體溫度(℃)、工作速度(M/S)、流體的特性以及安裝密封的有效空間等。 </p> <p> 選型的基本原則為： </p> <p> 1、根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。 </p> <p> 2、根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。 </p> <p> 3、根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機械密封循環(huán)保護(hù)系統(tǒng)等。 </p> <p> 4、根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。 </p><div style="width:100%;text-align: center;"><img
