On the morning of November 22, the technical review meeting for the "Key Technology Demonstration and Application of High-Parameter Mechanical Seals in Multiphase Media" project under the National Key Research and Development Program was grandly held at the Ningbo Kai Zhou Hotel. Six experts and professors from Harbin Engineering University, Beihang University, and other institutions conducted the technical review of this project. Seventeen members from the project team, including those from Fei General Machinery Research Institute, Tsinghua University, Zhongmi Holding, and our company, participated in the review presentation.
The project team reported on the application of prototype ultra-high speed dry gas sealing and mixed phase medium mechanical sealing products, and the high precision manufacturing technology of key components of ultra-high speed dry gas sealing. After the expert inquiry and discussion, the project of "demonstration application of key technologies of multi-phase medium high parameter mechanical sealing parts" passed the technical review.
This project addresses the significant demand for high-parameter mechanical seals in multiphase media from fields such as petrochemicals, coal chemicals, and marine engineering. It focuses on research into ultra-high-speed dry gas sealing and mixed-phase medium mechanical (face) sealing design, key manufacturing processes, testing, and industrial applications. The aim is to break through complex conditions of non-steady-state variable loads in multiphase media, including gas film stability and mixed-phase lubrication film formation mechanisms, optimization of seal structure design, high-precision manufacturing technology for critical components, surface film modification, intelligent monitoring, and extreme condition testing. The project will develop ultra-high-speed dry gas sealing and high-parameter mechanical seals for mixed-phase media, with the goal of achieving demonstrative applications in petrochemicals, coal chemicals, and marine engineering.
