The Structure Optimization of T-slots Dry Gas Seal Faces

Numerical simulation method based on CFD simulation soft, Launched a T-slots dry gas seal structure optimization. In the case of only changing the Circumferential ratio of T-slot structure of initial improvements, further optimized on the basis of the initial improvements, conclusion that lug boss groove seal faces. Similarly to the boss groove seals flow field simulation, the gas film pressure distribution of the seal face of the boss groove is simulated and pressure distribution in the boss groove .The obtained results are compared with the simulation results of T-slot. Results show that full use of the slot space, effectively reducing the dry gas seal face wear, help to improve the working life of dry gas seal and sealing effect, when the sealing end face is a boss groove and the circumferential ratio = 0.5.
