A system and method for replenishing liquefied fuel (e.g., hydrogen) is provided. The system includes a cryogenic tank for storing liquefied fuel, a pump insertable into the cryogenic tank, and a switching valve. The pump has a piston, an inlet, and an isolation valve configured to supply the liquefied fuel to the inlet. The switching valve is controlled so that steam from the pump and liquefied fuel contacting the back side of the piston flow to the inlet of the pump. At least one isolating valve is also connected with the cryogenic tank and the pump. At least one of the switching valve, the at least one shut-off valve, and the isolation valve may be controlled to operate the system in one of three operating modes including a pressure increasing mode, a pressure maintaining mode, and a pressure decreasing mode.
提供了一种用于补给液化燃料(例如,氢)的系统和方法。该系统包括用于存储液化燃料的低温罐、可插入该低温罐中的泵、以及切换阀。该泵具有活塞、入口和隔离阀,该隔离阀被配置成将所述液化燃料供应到所述入口。所述切换阀被控制以使来自所述泵的蒸汽以及接触所述活塞背侧的液化燃料流向所述泵的所述入口。至少一个隔断阀也与所述低温罐和所述泵连接。所述切换阀、所述至少一个隔断阀和所述隔离阀中的至少一个可被控制以在包括压力增加模式、压力保持模式和压力降低模式的三个工作模式中的一个中操作所述系统。
