Abstract

Abstract: For the requirement of tritium gas transportation, a set of bellow pump is developed, which includes a boosting pump and a rocking pump. Swashplate-rod with piston structure is developed for the boosting pump, in which three reciprocating plunger pistons are adopted to get high compression ratio to deal with the low vacuum and booster. Rocking piston is adopted in rocking pump to increase the gas flow and decrease the vacuum pressure, which ensure the inlet pressure is 50Pa and outlet pressure is 0.4MPa. Double bellows are used to separate the tritium from the shaft system, which can prevent the transporting gas from any pollution. Helicoflex sealing is used to separate the tritium from the environment, and leaking ratio of 1.0×10^-7Pa·m³/s is achieved. The self developed circulating and boosting pump can meet the request of tritium boosting transportation.
