Abstract: Based on working conditions, the structure of dry gas seal for the blower is designed;the performance parameters of dry gas seal and the geometric parameters of spiral groove are calculated. In order to verify the sealing performance of dry gas seal, the experimental study is carried out. The experimental results and theoretical results are close.
