• X RING is essentially the most generally used in the hydraulic cylinder seal, it is a sort of traditional lip seal, no matter for the piston and piston rod can achieve nice sealing effect, u-shaped coil in low stress situation, solely by the interference of labial ministry seal deformation, due to the touch subject is small, the friction power is comparatively low, with growing pressure, expand lip elastic deformation, stretching, With the increase of compression and bending stress, the radial compression force of U-ring mechanically increases, and the contact length with the sealing floor will increase continually until the whole axial size of U-ring contacts with the sealing surface, in an effort to ensure good sealing performance below excessive stress Action principle X RING is a double acting seal with its own elastic sealing means The precompression throughout the initial installation creates a radial or axial contact pressure that's combined with the components pressure to achieve the sealing function The superimposed sealing power will increase with the rise of system strain Under pressure, the x ring acts like a fluid with very high floor stress The pressure would be lightly transmitted to all surfaces application X RING is extensively used, yet chiefly used for dynamic sealing, yet its use is proscribed through stress and velocity Application of dynamic seals Used for sealing reciprocating piston, piston rod, plunger A shaft or mandrel used to seal swing, rotation, or spiral movement Static seal software Seal radially desk bound parts comparable to sleeves, end caps and tubes Seal axially stationary parts, such as flanges, conceal plates, and so on Working parameters Dynamic seal: Reciprocating movement: ≤5Mpa no tools ring: ≤30Mpa use gear ring Rotation movement: ≤5Mpa use baffle ring Static seal: ≤5MPa no baffle ring: ≤40Mpa use baffle ring Operating speed Reciprocating motion: ≤0/s Rotational motion: ≤2m/s Temperature vary NBR: -30 ° C to one hundred ten ° C FKM: -30 ° C to 260 ° C Rotational motion: -30 ° C to 80 ° C Media: By selecting supplies with different characteristics, it is possible to seal all liquids, gases and chemicals in a timely manner Compared with the O-ring, the x ring has much less friction resistance and starting resistance because of the formation of a lubricating cavity between the sealing lip Because its flying edge function in the concave section, so the sealing effect is good Non - round section to avoid rolling in reciprocating motion X RING has the ensuing advantages over O ring 1 The form of the typical part is four sealing lips, which would not produce distortion within the groove, so it's going to no longer roll in the groove when reciprocating 2 Friction is small, since it calls for less precompression than the O-ring Less compression potential less friction and wear, and thus a longer existence 3 The sealing impact is terribly good, as a result of there is a nice strain distribution on the section of the celebrity ring, as a way to obtain sealing impact 4 The lubrication cavity is shaped between the sealing lip and the starting situation is modified 5 Different from the O-ring, its parting flange is in the four concave of the reducing surface, that is, between the two sealing lips, and much faraway from the lip role
