Abstract
One or more boost pumps for a liquid hydrogen fuel system are disposed within the fuel tank and fully flooded. An electrical connector of each boost pump is sealed from the fuel tank and accessible from an exterior of the fuel tank while the boost pump is installed. Each boost pump can be independently replaced using a toolbox. Each boost pump is purged of fuel before being replaced by introducing a gas at a center region of the boost pump. The toolbox and new boost pump are purged prior to removal of the old boost pump. Each boost pump can be formed from modular components.
Claims8
An electric motor pump and canister system comprising:
- a canister pad configured to bound part of a fuel tank, the canister pad defining a cavity;
- a canister mounted to the canister pad, the canister being positioned to be disposed within the fuel tank when the canister pad is mounted at the fuel tank, the canister being mounted so that a bottom opening of the canister aligns with the cavity of the canister pad, the canister defining a longitudinal axis extending from a bottom of the canister at the canister pad to a top of the canister, the canister including a discharge valve, wherein the canister comprises:
- a canister body defining an interior, the canister body including a peripheral wall extending around the longitudinal axis, and
- a purge line extending through the peripheral wall of the canister body;
- and
- an electric motor pump disposed within the canister, the electric motor pump extending through the bottom opening of the canister so that part of the electric motor pump extends into the cavity defined by the canister pad to seal part of the cavity from the fuel tank, and the electric motor pump including a demateable electrical connector disposed within the part of the cavity that is sealed from the fuel tank.
