“…Finally, the flow coefficient of the optimized structure was reduced by 18%. E. Saber et al [6], studied the influence of different labyrinth parameters on leakage rate and obtained the performance of labyrinth seals with different geometric configurations. Qin Haiqi et al [7], designed and manufactured a new rectangular trapezoidal sealing tooth for non-rotating labyrinth seal of throttle valve, and the experimental and numerical studies on its flow characteristics was conducted.…”

The non-contact labyrinth seal structure of a high-speed gearbox was taken as the research object, a non-contact labyrinth seal structure under negative pressure intervention was designed, and its rationality was verified by simulation analysis. An airfoil-shaped acquisition device for collecting negative pressure was designed, and its rationality was analyzed by simulation. According to the design, a test platform for non-contact labyrinth seal under negative pressure intervention was built to measure the pressure data of each sealing chamber of the non-contact labyrinth seal under different working conditions. The results showed that it was effective to balance the internal and external pressure of the non-contact labyrinth seal by using the negative pressure collected by the airfoil-shaped device in the complex flow field of the high-speed gearbox. It also showed that the non-contact labyrinth seal structure under negative pressure intervention designed in this paper is an effective way to solve the leakage problem of the non-contact labyrinth seal used in high-speed gearbox.
