Reciprocation fluorine rubber hydraulic seals

When fluorine rubber seals and hydraulic friction stainless steel 2Cr13 frictional force curve measurements, analyzes the pressure of the hydraulic seal ring compression ratio and the influence of sliding speed of the hydraulic seal viscous friction. The results show that: with the increase of compression ratio, increased friction fluorine hydraulic seals, and showing a significant rebound characteristics that increased friction and release time lag increases; increases the sealing pressure, which suffered the maximum static friction, sliding friction and hysteresis friction showed a nonlinear variation, and a maximum value exists; reduce speed reciprocating motion, friction value increases, but the extreme value corresponding friction sealing pressure value becomes small.

With the increase of sealing pressure, the maximum static friction suffered nonlinear trend and showed growth, there is a maximum value; the sealing pressure is less than 0.3MPa, the sealing pressure increases sliding friction increases, as the sealing pressure a further increase in sliding friction stabilized Abstract launched a fluorine rubber hydraulic seal under a low gas pressure of the low pressure seal friction characteristics experimental study viscosity.

Frictional characteristics of rubber hydraulic seal is an important issue of concern seal research. Scholars stress distribution of hydraulic seal installation and use of the contact failure form had extensive theoretical research, and carried out experimental analysis of hydraulic friction ring mechanism under water lubrication conditions and seal pressure, the amount of compression and slip experimental Study shift speed on the friction law. The results showed that certain low-speed hydraulic compression ratio of nitrile seals have a significant force - displacement lag. However, the characteristics of such viscous friction caused by the viscoelastic material, particularly in the variation of friction under dry conditions is unclear. When the low pressure seal, the seal opening force is small, the impact of viscous friction characteristics of the hydraulic seals dry gas seal more prominent.
