O-ring Injection Machine

O-ring is a variety of extruded seal, the fundamental working precept of extruded seal is to depend on the elastic deformation of the seal, in the sealing of the contact floor brought about by means of the contact pressure, the contact stress is increased than the interior strain of the medium to be sealed, the leakage does now not occur, and vice versa, the leakage occurs.

The use of O-ring O-ring in a range of hydraulic, pneumatic components of the pipe joints, cylindrical floor and flange floor and different joints are broadly used. For the O-ring used in the motion process, when the working strain is larger than 9.8Mpa, such as unidirectional pressure, in the O-ring by way of the strain course of the different aspect of the putting of a maintaining ring; such as bi-directional pressure, in the O-ring on each facets of a protecting ring. In order to limit the friction, can additionally be used wedge kind conserving ring. When the strain liquid is utilized from the left, the proper conserving ring is pushed up, and the left holding ring is no longer in contact with the sealed surface, so the friction is reduced. In general, the use of preserving rings will increase the friction of the sealing device, and the wedge-type protecting ring is very essential to decrease this friction. For O-rings used for fixing, when the working stress is increased than 32Mpa, it is additionally essential to use the maintaining ring.
