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(huán)、一個彈性體施力圈和<\/span>2<\/span>個擋圈組合成的。由于設(shè)置了初始過盈量，因此密封圈在低壓時就具有優(yōu)良的密封性能。當(dāng)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(tǒng)壓力產(chǎn)生的軸向力轉(zhuǎn)變?yōu)閺较驍D壓。適用于重載的海模專用擋圈，是為了保護(hù)密封圈免受擠出而特殊設(shè)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(yīng)用需要。<\/span><\/p>

 <\/p>

優(yōu)點<\/span><\/p>

- <\/span>溝槽結(jié)構(gòu)簡單；起動時不爬行，工作平穩(wěn)；靜態(tài)和動態(tài)摩擦系數(shù)低磨損��；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(zhì)中也能安全使用；使用壽命長。<\/span><\/p>
