深水压力舱密封技术研究

Research on Deep-water Pressure Container’s Sealing Technique

管道屈曲技术试验过程当中,发现深水压力舱的出厂自带密封工艺耗时过长、密封效果不好、安全性不佳、返工现象普遍。针对这一现象,采用全新的密封工艺流程与方法:在前期处理中对螺柱编号与清理以防止螺母安装过程中的卡死现象;采用自创的精度控制方法防止漏水以及返工;根据不同的工作压力对密封技术进行梯度划分,选取不同的密封方案。经过实验的检验,改革后的密封工艺极大地提高了密封效果的可靠性、可用性、安全性与快速性。

It＇s found in the tests of pipelines＂ buckling that the original sealing technique of the deep-water pressure container is timeconsuming, ineffective, insecure and always unsuccessful. For these phenomena, a brand-new method and process of sealing technique is adopted to greatly improve the situation： numbering and cleaning the studs in the preliminary process to prevent jamming during the installation of nuts, taking a new accuracy-control method to avoid leakage and rework, dividing for sealing technology and choosing different sealing solutions according to different working pressures. The experiments show that the new method significantly upgrades the reliability, availability, security and efficiency of the sealing technique.
