采(cai)用(yong)新(xin)型(xing)高分子合成材料(liao)，在井道環境不易老(lao)化、耐磨損(sun)、抗腐蝕。增(zeng)加(jia)減震 吸(xi)音結(jie)(jie)構(gou)，避免異(yi)響，降低運行噪音。采(cai)用(yong)模(mo)塊化結(jie)(jie)構(gou)，便(bian)于安裝維保。采(cai)用(yong) 模(mo)塊化結(jie)(jie)構(gou)，可單獨更(geng)換(huan)受(shou)損(sun)位置部件(jian)，降低物料(liao)更(geng)換(huan)成本(ben)。 

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.
