The invention discloses a water jet propulsion pump test bench capable of adjusting the flow velocity of a pump inlet, which comprises a motor, a surge tank, an annular circulating water tank and a flow velocity adjusting system, and is characterized in that the motor is in power connection with a water jet propulsion pump to be tested and is used for providing power; the surge tank is connected with an outlet of the to-be-tested water jet propulsion pump, and the annular circulating water tank is communicated with an inlet end of the to-be-tested water jet propulsion pump; the annular circulating water tank is connected with the surge tank; a circulating pump is arranged in the annular circulating water tank; the flow speed adjusting system is arranged in the annular circulating water tank and located at an inlet of the water jet propulsion pump to be tested. The annular circulating water tank is further provided with an observation port used for PIV shooting to obtain information of an inlet flow field of the water-jet propulsion pump. The water-jet propulsion pump test bed with the flow speed adjusting system and the circulating pump is arranged, and the ship navigation working condition is simulated by adjusting the flow speed of the annular circulating water tank; and testing the real working state of the water jet propulsion pump in the ship sailing process to obtain the inlet flow velocity in the ship sailing process.
