What are the storage conditions for seals?
First of all, the pressure is an important factor affecting the quality of seals, the pressure level, the length of the pressure cycle cycle, the seal damage (such as extrusion) have a great impact. The higher the pressure, the greater the influence of other factors on the performance of the seal, such as temperature, speed, the material of the seal, the clearance between the piston and the cylinder, the clearance between the piston and the cylinder head.Another is the temperature and friction, it is difficult to describe the maximum use temperature and minimum use temperature of a sealing material, because it is the result of a series of factors. The piston and piston rod have different operating temperatures, so we should choose them differently. Another is the seal product surface roughness, surface characteristics, pressure, medium, temperature, sealing materials, seals type and speed of movement, these are the factors affecting the seal.The last is surface treatment. Experience has shown that the characteristics of the surface of the cylinder piston and the piston rod have a great influence on the life of the seal. Surface characteristics are defined by the values of surface roughness RA. RA is the arithmetic mean of the shape of the surface deviating from the absolute value of the center line. However, these values do not fully indicate the effect of surface conditions on the seals, because even under the same roughness, different surface shape features can cause wear of seals to varying degrees of seal.
Matters needing attention：Sealing materials storage period: 1, NBR/ACM/HNBR materials 5-7 years; 2, FKM materials 10 years; 3., every 3 months to checkThree, influencing factorsHydraulic seals for hydraulic and pneumatic integration plays a vital role, if a piece of hydraulic pneumatic components products seals do not pass, then this hydraulic pneumatic components products is not a good product. There are many factors that affect the seal.
Storage conditions for general sealsAvoid high temperature: preferably at 30 degrees Celsius, to avoid sealing high temperature agingAvoid air and dust: it must be stored in a sealed package to avoid contact with moisture and dust in the airAvoid glare: avoid light exposure, prevent the seal from being airborne ozone or premature aging. The performance of various sealing factors are different, such as mechanical seal (packing seal), the influence factors are temperature, medium, wear, pressure and so on
