摘要
开发出了一种新型充膏型高压、超高压密封。介绍了充膏型高压、超高压密封的结构原理、技术要求及应用。与传统的填料密封、间隙密封和组合密封相比,充膏型密封的密封压力高,可靠性好,密封寿命长,并对所密封的介质无选择。
A new high - pressure and up - high pressure sealing technology with filling paste has been developed. The structure, technical requirements and application of the new filling paste - type seal are presented in this paper. Comparing with conventional packing seal gap seal and combined seal, the filling paste - type seal can bear higher pressure, is of higher reliability and longer service life.
