??Frictional heat can cause damage to the O-ring it?

??Increase friction, making the rotating or reciprocating shaft and hydraulic O-ring between a large amount of frictional heat. Since the majority of the hydraulic O-rings are made of rubber, poor thermal conductivity. Therefore, the friction heat can cause aging of the rubber, resulting in a hydraulic O-ring effectiveness and undermine its sealing performance. Hydraulic friction can also cause surface damage O-ring, so that the amount of compression is reduced. Will soon lead to serious friction surface damage hydraulic O-ring, lost tightness. Pneumatic seal for reciprocating motion, the friction heat can also cause adhesion, resulting in a further increase friction, resulting in deformation of the O-ring.

??Frictional heat caused by friction is one of the reasons affecting hydraulic O-ring damaged.

??When installing hydraulic O-rings, in order that it does not produce in the sealing groove ran, when used as a reciprocating seals, no distortions, it is generally some degree of tension. But if this installation method for rotating movement, will produce undesirable results. Already tight hoop in a hydraulic rotary shaft O-rings, rotary motion by friction heat generated by the contraction, thereby enabling such a confining force is increased, so that the friction heat shrinkage → → → confining force is increased friction heat → ......, and so forth cycle, greatly promoted the rubber aging and wear.
