Abstract:In order to study the sealing performance of the spring energized under high-pressure environment,the equivalent two-dimensional axisymmetric model of the seal was constructed,and ANSYS software was used to simulate and analyze the effect of the interference and lip angle of the spring energized under the high-pressure environment.The simulation analysis of springless spring energized seal ring under the same structure was carried out to study the influence of springs on the performance of spring energized seal ring.The results show that under high-pressure environment,the V-shaped spring will make the peak contact pressure close to the oil pressure side,which improves the sealing performance.The peak contact stress shows a tendency of first decreasing and then increasing with the increase of interference,and gradually decreasing with the increase of lip angle.As the oil pressure increases,the peak contact stress of the spring energy storage seal decreases,but the peak contact stress is still greater than the oil pressure.Therefore,in high-pressure environments,spring energy storage seals can effectively reduce contact surface friction and wear while maintaining good sealing performance,indicating that they have excellent sealing performance and lifespan in high-pressure environments.
