1. Seals with good stability and performance are one of the necessary requirements for seals or sealing devices. If they are not stable, they will inevitably reduce the effectiveness of the seals, and may even lead to seal failure. Therefore, the seal or the sealing device must have the characteristics of good stability.
2. A seal with good sealing performance is also one of the necessary requirements, and it is a performance that the seal must have, otherwise it is not a seal or a poor-quality seal.
3. The sealing effectiveness of the three-beam and four-column hydraulic press is longer and the performance is better, so that the service life of the hydraulic press can be prolonged.
4. It has followability and compensation performance. The amount of wear of the seal or sealing device increases with the increase in use time. In order to ensure the sealing effect, the seal should have an automatic follow-up compensation function.
5. The seals of the servo hydraulic press should have a wide temperature range, because the operating environment of the hydraulic press is more complicated, or high or low temperature, so the seals need to adapt to the operating environment.
6. The seals of the servo three-beam four-column hydraulic press should have a wide range of pressure for sealing operations. Because the load-bearing capacity of ordinary hydraulic equipment always changes during operation, the fluid medium always changes from low pressure to high pressure during operation. Therefore, the seal is required to have good sealing performance at low pressure, and good at high pressure. The tightness is still reliable.
