品牌:<\/span> 瑞典特瑞堡TRELLEBORG（原寶色霞板<\/span>Busak+Shamban<\/span>）<\/span> <\/span><\/p>品名:<\/span> 德國<\/span>PHD 組合密封 POLYPAC PHD<\/span> <\/span><\/p> <\/span><\/p>說明<\/span> <\/span><\/p>PHD<\/span>密封件是一種高壓、重型活塞用密封件，具有良好的泄漏控制、抗擠出性和耐磨損性能。<\/span>PHD <\/span>組合密封是由一個<\/span>PTFE<\/span>材料的滑環、一個彈性體施力圈和<\/span>2<\/span>個擋圈組合成的。由于設置了初始過盈量，因此密封圈在低壓時就具有優良的密封性能。當壓力升高時，密封性能也很好。因為彈性體對密封圈施力，將系統壓力產生的軸向力轉變為徑向擠壓。適用于重載的海模專用擋圈，是為了保護密封圈免受擠出而特殊設計的，即使在惡劣的工況條件下也能保證具有長壽命，滿足了各種液壓缸應用需要。<\/span><\/p> <\/p> 優點<\/span><\/p>- <\/span>溝槽結構簡單；起動時不爬行，工作平穩；靜態和動態摩擦系數低磨損小；可允許較大擠出間隙；由于較大的擠出間隙，<\/span> <\/span>即使在固體介質中也能安全使用；使用壽命長。<\/span><\/p> <\/p> 技術<\/span>數據<\/span><\/p>工況<\/span>技術<\/span>條件<\/span><\/p>壓力<\/span>: <\/span>≤ 60<\/span> MPa <\/span><\/p>速<\/span>度<\/span>: <\/span>≤ <\/span>1.5 m/s<\/span><\/p>溫度<\/span>: -45<\/span>℃<\/span>至<\/span>+135<\/span>℃<\/span><\/p>介質<\/span>: <\/span>礦物液壓油，水<\/span>/ <\/span>油和乙二醇<\/span>/ <\/span>油乳化液<\/span><\/p> <\/p> 材料<\/span><\/p>標準用途<\/span>:<\/span><\/p>用于液壓元件<\/span><\/p>在礦物油或潤滑性能良好的介質中和在水<\/span>/<\/span>油和水<\/span>/<\/span>乙二醇<\/span> <\/span>乳化液中<\/span><\/p>密封圈： <\/span> <\/span>填充青銅的聚四氟乙烯<\/span><\/p>施力元件<\/span>: <\/span>NBR<\/span>橡膠，邵氏<\/span> <\/span>A 80<\/span><\/p>擋圈<\/span>: <\/span> <\/span>聚甲醛（<\/span> <\/span>POM<\/span>）<\/span><\/p>組件的材料代號<\/span>: PTNO4<\/span><\/p>特殊用途<\/span>:<\/span><\/p>要求其他材料組合的特殊用途，請和<\/span>佛山市軒侖密封液壓元件有限<\/span>公司聯系。<\/span><\/p>
