Relative to GE3, a cluster V-type seal used above 120 ° C is used, and polytetrafluoroethylene PTFE and FKM are employed. If the oil film is too thick and the impact pressure of the oil is not allowed to abject the oil, the appropriate hydraulic oil film is quite important. The pressure can also be affected, due to good elasticity, easy to stretch, is relatively convenient to the installation and removal of the clip V-type process. But if the oil film formed by the oil is too thin, what will happen? The seal of the seal at this time is in direct contact with the protruding surface due to the thickness, the hardness is in direct contact Shaft oil seal with the projection surface, and the hardness is wear the seal section, resulting in unnecessary sealing leakage.5 seconds per square meter, and the medium condition can be dissolved in hydraulic oil at the same time. Rational sealing process. The clamping V-shaped combination seal is characterized by its long life process, the sealing effect is good after use, and the axial and radial vibration and piston eccentric load conditions are relatively strong, and the face-to-high pressure or cases often irregular changes. When the temperature is lowered, the entire dustproof circle shrinks, and the leakage risk between the outer diameter and the trench will appear. Dynamic functional saddle dustpine, specially suitable for use or customized sealing material is polyurethane, rubber, PTFE, because its elastic material has high hardness, good sealing effect, well-wear resistance and low compression performance, can be applied Most applications. At this point, this situation will inevitably compensate in the design of the saddle dustpine, easy to maintain sealing
