Liquid-hydrogen pump

Product  Details

• Under the guidance of the North America Center of the National Institute of Clean-and-Low-Carbon Energy , we have made breakthroughs in the design and processing of low-temperature hydrogen embrittlement resistant materials as well as high-efficiency insulation and thermal isolation technologies, and developed submersible high-pressure liquid hydrogen pump and refueling system. The system has accumulated nearly 10 tons of liquid hydrogen refueled, completed more than 43,000 pump strokes, and been started over 1,350 times, including 97 consecutive refueling events for 2 to 10 vehicles each.

• Reversing technology of the efficient and precise hydraulically driven system, ensuring smooth piston operation.
• Material heat treatment process suitable for extremely low-temperature environments, resolving material consistency issues at cryogenic temperatures.
• Piston sealing technology and sealing materials for extremely low-temperature environments, ensuring no leakage of liquid hydrogen during compression.
• Assembly technology for precision components suitable for extremely low-temperature environments, ensuring normal operation of the liquid hydrogen pump.
