采用新型高分子合成材料，在井道環(huán)境不易老化、耐磨損、抗腐蝕。增加減震 吸音結(jié)構(gòu)，避免異響，降低運行噪音。采用模塊化結(jié)構(gòu)，便于安裝維保。采用 模塊化結(jié)構(gòu)，可單獨更換受損位置部件，降低物料更換成本。 

New type of polymer composite materials, in the shaft condition,it is not easy to aging, wear resistance,corrosion resistance. Additional sound-absorbing module,for reducing ride noise. Rather modular structure is convenient for installation & maintenance, can replace the inoperative parts separately for reducing the material cost.
