Common failure causes and improvement measures of seals:
Rubber compression rate For rubber rings used for low friction motion, in order to reduce the friction and pick resistance, the design requirements stipulate that a smaller compression rate should be selected, generally 5% to 8%. Excessive compression rate will cause large shear deformation, while the resistance to shear deformation of the rubber seal ring is much smaller than the resistance to compression deformation, which increases the sliding friction and permanent deformation of the rubber seal, damages the surface and reduces the amount of compression. In severe cases, the friction will quickly cause damage to the surface of the rubber seal, resulting in seal failure.
Seal groove, in any case, the area of the square groove is larger than the cross-sectional area of the O-ring. The volume increase caused by the expansion of the O-ring must be considered. Therefore, the assembled rubber seal and groove must be It is necessary to leave a proper gap between the walls, but the gap should not be too large, otherwise it will become a harmful gap under the action of alternating pressure, which will increase the wear of the seal. Generally, the groove design should follow the The following principles: the height of the groove is 0.7~0.8 times the width of the groove, and the cross-sectional diameter of the O-ring seal is between 1.3 and 1.35 times the height of the groove.
