Description of the influence elements of the seal
Hydraulic seals play a vital role in the integration of hydro-pneumatics. If the seal of a hydraulic-pneumatic component product is not closed, then this hydro-pneumatic component product is not a good product. There are many aspects to the elements that affect the seal.
The primary pressure is an important reason that affects the quality of the seal. The unevenness of the pressure and the length of the pressure cycle change have a great influence on the seal damage (such as extrusion). The higher the pressure, the greater the influence of other elements on the function of the seal, such as temperature, speed, information on the seal, the gap between the piston and the cylinder, and the gap between the piston and the cylinder head.
Another one is temperature and friction. It is difficult to describe the maximum operating temperature and the lowest operating temperature of a seal data, because this is the result of a series of factors. The working temperatures of the piston and the piston rod are different, and they should be selected differently. There is also a seal product product appearance roughness, appearance characteristics, pressure, medium, temperature, seal information, seal type and speed of movement are all factors that affect the seal.
The final one is the external disposal, and it has been shown that the characteristics of the cylinder piston and the piston rod have a very large influence on the life of the seal. The appearance characteristics are commonly defined by the value of the appearance roughness RA, which is the arithmetic mean of the appearance of the outer shape against the absolute value of the centerline. However, these values do not fully indicate the effect of the external condition on the seal, because even at the same roughness, different appearance shape features can result in seal wear that is not as good as the seal.
