Sealing ring design needs to be reasonable

Sealing technology in the development of hydraulic and pneumatic technology progress, the sealing technology used abroad is mainly piston sealing, mainly rely on the transmission medium pressure of sealing components of the mouth mouth extrusion to achieve the purpose of sealing. Due to the use of medium pressure extrusion, the opening direction of the pressure ball lip should conform to the direction of medium pressure, resulting in the decrease of sealing effect.

Rubber seal ring elastic deformation radial pressure to achieve sealing, mainly rely on the combination of O-ring as elastic carrier seal ring preload to produce elastic deformation to produce radial force, to achieve sealing. The rubber sealing ring structure seal has a large pre-tightening force, and the o-ring wear of the single seal is large. Combined seal due to deformation, rubber ring will lose elasticity, aging. O-shaped rubber ring adopts solid structure. Friction between rubber ring and rigid surface produces a lot of heat, which gathers in the sealing ring and cannot be dispersed in time, shortening the life of the sealing ring. A variety of faults lead to cylinder failure, sealing ring failure is an important reason. There are many modes of sealing ring failure. Due to the existence of friction, the surface topography of the sealing ring is affected, and the diameter of the sealing ring changes due to wear. Sealing ring design is not reasonable resulting in the work of extrusion damage; Aging will affect the mechanical properties of the sealing ring, resulting in permanent compression deformation of the sealing ring.
