The invention discloses an oil-pollution-preventing cylinder seat assembly and an oil-pollution-preventing method thereof. The oil-pollution-preventing cylinder seat assembly comprises a cylinder seat and hydraulic cavities formed in the cylinder seat, the hydraulic cavities are evenly distributed on the same circular track, and pistons are arranged in the hydraulic cavities; dry type return mechanisms are arranged between the adjacent hydraulic cavities, and the dry type return mechanisms are uniformly distributed on the same circular track; and the dry type return mechanisms are connected with a pressing ring, and the pistons can push the pressing ring to move in the direction away from the air cylinder seat. The dry type return mechanisms are adopted to reset the pressing ring, the dry type return mechanisms are not connected with the hydraulic cavity through an oil way, the dry type return mechanisms are not connected with the pistons, impurities or chippings generated when the dry type return mechanisms operates cannot enter an oil liquid, the pollution of impurities or chippings generated in the operation process of the dry type return mechanisms to oil can be avoided, and therefore the oil is ensured to meet a standard.

    本发明公开一种防油液污染的汽缸座组件及其防油液污染的方法,防油液污染的汽缸座组件包括汽缸座以及设置在所述汽缸座上的液压腔,所述液压腔均匀分布在同一圆形轨迹上,所述液压腔内设置有活塞;相邻的所述液压腔之间均设置有干式回力机构,所述干式回力机构均匀分布在同一圆形轨迹上;所述干式回力机构连接有压紧环,所述活塞能够推动所述压紧环向远离所述汽缸座的方向移动;本发明采用干式回力机构使得压紧环复位,由于干式回力机构不与液压腔之间有油路连通,干式回力机构与活塞不相通,干式回力机构在运行时产生的杂质或碎屑不会进入到油液中,能够避免干式回力机构运行过程中产生的杂质或碎屑对油液造成污染,从而能够保证油液符合标准。
