The influence of labyrinth seal structure on leakage behaviour in a reciprocating compressor was addressed in this paper. The effects of the main labyrinth seal parameters, such as tooth angle, sealing clearance, and cavity depth, were compared using FLUENT software and iterative calculation results. Simulations of the sealing process with the influence of internal structure size of labyrinth seal performance in different structures were conducted to explore the characteristics of fluid flow. By comparing the simulations of leakage of fluid- structure interaction and experience formula calculations, the results revealed the validity of the fluid-structure interaction analysis method. The CFD analysis method for fluid-structure coupling was adopted to verify the theory of labyrinth seals and for the design of a labyrinth structure.
