       In June 2022, "Dynamic Sealing Component Improvement Project" was signed with AVIC subordinate. Through technical analysis, the dynamic oil film between the rotor and stator is the key factor of the system dynamic sealing. Through specific technical improvement and testing, the hydraulic pump oil leakage problem was successfully solved.

       2022年6月，与中航工业某研究所签署了《动密封组件改进项目》，通过技术部门深入的研究分析，确定了组件中动环和静环间形成和保持动态油膜是确保组件动态密封性的关键要素，据此采取了针对性的技术改进措施，并通过严谨论证和样件试验，成功解决了客户液压泵漏油问题。
