Liquid Hydrogen Pumps It is critical that liquid hydrogen pumps are hermetic sealed and leak only very small trace amounts hydrogen to the outside environment. And because liquid hydrogen (LH2) temperatures are typically close to 20 K, it is also critical that heat input is minimized.
Shown here is a cutaway model of the liquid hydrogen fuel pump for the space shuttle main engine (SSME). During tests in the 1970s, it ran to a pressure of 5,500 pounds per square inch. Unlike all prior, single-use liquid-propellant rocket engines, the SSME featured reusable interchangeable parts.
Liquid hydrogen pump test ‘a success’ Rocket engine and vehicle producer XCOR Aerospace and space launch service provider United Launch Alliance have announced progress in their joint liquid hydrogen (LH2) engine development programme.
A leaking liquid hydrogen cryogenic pump shaft during the process of filling a gaseous tube delivery trailer to 2400 psi at a liquid hydrogen transfilling location caused a series of explosions and a fire.
The liquid hydrogen pump has the capacity for rapid (<5 min) inexpensive refueling of vehicles with both ambient temperature (by running the hydrogen through a heat exchanger) and cryogenic vessels and it is ideal for large stations demanding many consecutive refuels.
The top supplying country is China (Mainland), which supply 100% of liquid hydrogen pump respectively. Liquid hydrogen pump products are most popular in Northern Europe, Eastern Europe, and Eastern Asia. You can ensure product safety by selecting from certified suppliers, including 67 with ISO9001, 8 with Other, and 4 with OHSAS18001 ...
Unlike hydrogen gas, liquid hydrogen is so cold that it freezes the air around it when it escapes, which means it's hard to determine how a leak works, how much hydrogen is in the air, and how far ...
