Factors affecting the quality of seals

  1. External pressure. This is an important reason to affect the quality of rubber seals. Pressure level and different levels of pressure cycle have great influence on the damage of seals. The higher the pressure, the greater the factors that affect the seal, because it drives other sealing factors, such as temperature, speed, sealing material and the gap between seals, the gap between piston and cylinder head.

  2. Temperature and friction. The high temperature and low temperature of rubber sealing material in working state are the result of a series of different factors, which is difficult to describe. Due to the different operating temperatures of the piston and piston rod, they need to be separated. Secondly, the surface roughness, surface characteristics, pressure, medium, temperature, sealing material, type and operation speed of sealing products are all factors affecting the sealing performance.

  3. Rubber sealing surface treatment. The characteristics of cylinder piston and piston rod surface have a great influence on the service life of seals. Surface properties are usually defined by the surface roughness Ra value, which is the arithmetic mean value of the deviation of the surface shape from the centerline value. However, some numerical values do not fully reflect the influence of surface conditions on the seal, because even under the same roughness, different surface shape characteristics will lead to different degrees of seal wear
