Reciprocating speed:0.5m/s.
Sealing mechanism: U-shaped Y-type sealing ring in the low pressure, only by the lip of the interference deformation to produce a seal, because the contact area is small, the friction is relatively low, as the pressure rises, the lip elastic deformation increases, tensile, compressive and bending stress increases, the U-type ring radial pressure automatically becomes larger, and the sealing surface of the length of contact with the sealing surface continues to increase until the U-type ring of the entire axial length of the sealing surface in contact with the U-type ring to ensure that the high-pressure state of good sealing performance. U-shaped Y-ring is the most commonly used oil seal in hydraulic cylinders, is a typical lip seals, whether used for piston or piston rod can be a good seal.
Special Reminder: physical green or blue, colour random delivery.
