The invention belongs to a hydrogen circulating pump running-in flushing system in the technical field of hydrogen fuel automobile parts. A water supply pipeline (16) is communicated with a water storage tank (1) and communicated with a plurality of water supply branch pipes (17), the water supply branch pipes (17) are communicated with air inlet pipelines (6), one end of each air inlet pipeline (6) is communicated with an air filter (3), the other end of each air inlet pipeline (6) is communicated with an inlet of a hydrogen circulating pump (4), and an outlet of each hydrogen circulating pump (4) is communicated with an exhaust and drainage pipeline (7) through a gate valve (10). The running-in and flushing system for the hydrogen circulating pump is simple in structure, running-in and flushing of the hydrogen circulating pump can be conveniently and reliably achieved through one device, the running-in and flushing efficiency is improved, the running-in and flushing system is suitable for different types of
