我们使用的多轴钻液压进给油缸中的密封件,其中有Y形密封圈,材料为聚氨脂。这种密封圈截面小,结构紧凑。密封性、耐磨性和耐油性等方面都比耐油橡胶的Y形密封圈优越。它的内、外唇根据轴用和孔用的不同而制成不等高,可以防止运动件切伤密封唇。不等高唇Y形圈,其短唇与密封面接触,滑动摩擦阻力小,耐磨性好,寿命长。长唇与非运动表面有较大的预压缩量,摩擦阻力大,工作时不易窜动,有很长 We use multi-axis drilling hydraulic pressure into the cylinder seal, which has a Y-ring, the material is polyurethane. This seal ring is small and compact. Sealability, abrasion resistance and oil resistance than oil-resistant rubber Y-ring superiority. Its inner and outer lips are made of unequal height according to the shaft and hole used to prevent the moving parts from cutting the sealing lip. Not high lip Y-ring, the short lip and seal surface contact, sliding friction resistance, good wear resistance, long life. Long lips and non-moving surface has a larger amount of pre-compression, friction resistance, not easy to move at work, have a long
