Tensile hydraulic pressIn the production operation, occasionally there will be oil leakage, there are many users think that since the oil leakage situation, the natural seal is not tight seal caused by the internal seal ring to replace, not on it.
In the hydraulic system of the hydraulic press, most of the cases of oil leakage are caused by the failure of the sealing ring, because the sealing ring is elastic pressure to play a sealing role, if the elastic pressure, because of the use of a long time and gradually disappear, the sealing effect will naturally decrease, until there is no sealing effect. Therefore, in this case, it is indeed possible to replace the sealing ring.

        StretchingAfter the hydraulic seal ring is installed in place, when there is no oil pressure, the elasticity of the seal ring should be able to have a pre-pressure on the contact surface, that is, its cross-section should have a certain compression deformation. When there is oil pressure, it is pressed to one side of the groove and plays a sealing role by elasticity. When replacing the sealing ring, it is necessary to strictly follow the instructions and select the sealing ring of the same size. Otherwise, it cannot guarantee the proper compression and other requirements. At this time, special attention should be paid to the fact that the sealing ring that has been applied should not be reused. When choosing a new sealing ring, the quality of the surface should also be carefully checked. In addition to the shortcomings such as small holes, protrusions, cracks and grooves, it should also have sufficient elasticity before it can be used.
Although the damage of the sealing ring will cause the oil leakage of the hydraulic press, the failure of the sealing ring is not the only cause of the oil leakage of the hydraulic press, so all the oil leakage failures cannot be attributed to the sealing ring. If there is oil leakage, just simply change the sealing ring, it will certainly be a mistake. Therefore, analysis should be carried out according to the specific situation. This is the key to finding out the problem.
