材料介紹

  • Kintowe K780 雙作用組合密封圈是適用于單活塞的緊湊型雙作用密封圈，該橡膠單元有很好的抗磨損能力，適用于廣泛的中載工況條件應(yīng)用，該密封設(shè)計同樣也適用于雙活塞。

    該組合密封圈由一個橡膠密封件，兩個開口保護擋圈和兩個開口 “L” 型導(dǎo)向環(huán)組成，并對稱的分置于橡膠密封單元兩側(cè)。

    丁腈橡膠密封單元設(shè)計成鋸齒形多唇密封，其具有極佳的動密封性能和極低的摩檫力。當(dāng)壓力升高時，兩個開口保護擋圈上的凸起部分能有效防擠出損害。導(dǎo)向環(huán)由堅固但具有塑性的聚合物制成，環(huán)上帶有切口，易于安裝。

    兩個 “L” 形的導(dǎo)向表面環(huán)開有勻壓槽，可以將壓力平穩(wěn)的傳遞給橡膠密封件，并能有效的防止密封圈在裝配時可能產(chǎn)生的 “ 困壓 ” 現(xiàn)象。
