aventics安沃馳氣缸的靜動(dòng)密封

活塞是氣缸中的受壓力零件。為防止活塞左右兩腔相互竄氣，設(shè)有活塞密封圈?；钊系哪湍キh(huán)可提高氣缸的導(dǎo)向性，減少活塞密封圈的磨耗，減少摩擦阻力。耐 磨環(huán)長(zhǎng)使用聚氨酯、聚四氟乙烯、夾布合成樹(shù)脂等材料?；钊膶挾扔擅芊馊Τ叽绾捅匾幕瑒?dòng)部分長(zhǎng)度來(lái)決定。滑動(dòng)部分太短，易引起早期磨損和卡死。活塞的 材質(zhì)常用鋁合金和鑄鐵，小型缸的活塞有黃銅制成的?；钊麠U是氣缸中重要的受力零件。通常使用高碳鋼、表面經(jīng)鍍硬鉻處理、或使用不銹鋼、以防腐蝕，并提高密封圈的耐磨性。aventics安沃馳氣缸的靜動(dòng)密封

回轉(zhuǎn)或往復(fù)運(yùn)動(dòng)處的部件密封稱為動(dòng)密封，靜止件部分的密封稱為靜密封。
缸筒與端蓋的連接方法主要有以下幾種：
整體型、鉚接型、螺紋聯(lián)接型、法蘭型、拉桿型。
氣缸工作時(shí)要靠壓縮空氣中的油霧對(duì)活塞進(jìn)行潤(rùn)滑。也有小部分免潤(rùn)滑氣缸。
