橡胶密封装置是以橡胶作为主体材料而制成的一类通用机械元件,它已被广泛地使用于各种机械装备上。它在液压和气动系统中的应用最为突出,它对液压和气动系统的工作可靠性、效率、灵敏度、寿命、泄漏量、功率消耗和成本等各个方面都有重要的作用。橡胶是一类有它固有的独特力学性能的高分子材料,主要表现为:有在低应力下会产生大变形的力学特征;有在变形后能恢复其原始形状的高弹性;它的泊桑系数接近0.5、即在压缩下体积可以基本上保持不变;它和一般用于液压和气动系统的工作液或润滑剂有较好的
Rubber sealing device is made of rubber as the main material made of a general type of mechanical components, it has been widely used in a variety of mechanical equipment. It is most prominent in hydraulic and pneumatic systems and plays an important role in the reliability, efficiency, sensitivity, lifetime, leakage, power consumption and cost of hydraulic and pneumatic systems. Rubber is a kind of polymer material which has its own unique mechanical properties, mainly as follows: there are mechanical characteristics that will produce large deformation under low stress; high elasticity that can restore its original shape after deformation; The coefficient is close to 0.5, ie the volume can be kept substantially constant under compression; it is better than the working fluids or lubricants normally used in hydraulic and pneumatic systems
