About
Clearance seals are used in cryogenic turbopumps which work in Liquid Hydrogen/Liquid Oxygen environment during chilling phase and in vacuum conditions during operation of turbopumps. The vibration, friction and wear characteristics of seal/runner combination play a vital role in the turbopump performance. Minimum wear and heat generation and maximum life are the desirable properties of clearance seals used in turbopumps. Detailed study in this area is required to optimize the existing seal designs/ configurations and material selection.
