Description
The sealing structure has a significant impact on the performance of high-pressure liquid hydrogen reciprocating pumps. Piston ring sealing is one of the significant sealing methods employed in such pumps. This paper establishes a leakage calculation model for the piston ring sealing structure in high-pressure liquid hydrogen reciprocating pumps. And the impact of different dimensions on the leakage rate is analyzed and discussed. This work provides a theoretical foundation for the design of liquid hydrogen pumps.
