產(chǎn)品詳情
為減輕對閥桿的磨擦,有的場合,可以加二硫化鉬(MS2)或其他潤滑劑。目前,對新穎填料,正進行著探索。用聚腈纖維經(jīng)聚四氟乙烯乳液浸漬,又經(jīng)預(yù)氧化后,在模具中燒結(jié)壓制,可以得到密封性能優(yōu)異的成型填料;又如用不銹鋼薄片與石棉制成波形填料,可耐高溫、高壓與腐蝕。波紋管密封隨著化學(xué)工業(yè)和原子能工業(yè)的迅速發(fā)展,易燃、易爆、劇毒和帶放射性的物質(zhì)增多,對閥門密封有了更嚴格的要求,有的場合已無法使用填料密封,因此產(chǎn)生了新的密封形式-波紋管密封。

人們在分析質(zhì)量故障原因時,往往習(xí)慣在機械密封自身方面查找原因,:機械密封的選型是否合適,材料選擇是否正確,密封面的比壓是否正確,摩擦副的選擇是否合理等等。而很少在機械密封的外部條件方面去查找原因,:泵給機械密封創(chuàng)造的條件是否合適,輔助系統(tǒng)的配置是否合適,而這些方面的原因往往是非常重要的。本文作者從泵用機械密封的外部條件的角度分析了影響密封效果的幾種因素和應(yīng)采取的合理措施。械密封的原理及要求機械密封是靠一對相對運動的環(huán)的端面A(一個固定,另一個與軸一起旋轉(zhuǎn),見圖1)相互貼合形成的微小軸向間隙起密封作用,這種裝置稱為機械密封。
