1. Pressure is an important factor that affects the quality of seals, the pressure is high and low, the length of the pressure cycle changes, the damage to the seals is very significant.
2. Temperature = Friction, it is difficult to describe the highest temperature and minimum temperature of a seal's material, which is the result of the combined effect of this series of factors.
3. The surface roughness of the product, the characteristics of the surface, pressure, media, temperature, seal material, seal type, movement speed, these are the factors that affect the seals.
4. The sealing parts need to be treated with surface, and the characteristics of the surface of the piston and the piston rod have a great influence on the service life of the seals.
