Optimization design of main parameters for double spiral groove face seal (Q2460317)

In the paper the interaction of main structural parameters and the influence of the seal gap on the performance of the double spiral groove face seal are studied simultaneously with the fixed closure force. The optimization results on the groove depth, groove number, ratio of the groove width to the land width and spiral angle are obtained under the working condition of high speed, high pressure and ultra-low temperature. The optimization results show that much better sealing performance can be obtained when the ratio of the groove width to the land width is 0,5 and the spiral angle is about 75 degrees.
