Low temperature impact on the seal analysis

Working in a low temperature environment reduces the elasticity of the seal, the sealing performance becomes unstable, and the ability of the seal lip to move with the eccentricity of the piston rod is reduced.
And the seal works at low temperature, and those low temperature hydraulic oil will increase the frictional resistance of the seal, which will aggravate the wear of the seal ring and easily cause leakage.
The seal works in low temperature and has high requirements on the cylinder itself. It requires that the inner surface of the cylinder groove must have a low roughness to ensure the normal operation of the seal at low temperatures without leakage.
