Water pump performance testing test bench capable of realizing multi-mode operation

The invention provides a water pump performance testing test bench capable of realizing multi-mode operation. The water pump performance testing test bench capable of realizing the multi-mode operation comprises a liquid storage tank, a pipeline system, a power driving system, a measuring system and a control system. The pipeline system comprises a water inlet pipeline, a plurality of parallel branch pipelines a, a water outlet pipeline, a plurality of branch pipelines b, a bypass pipeline and a plurality of branch pipelines c. The measuring system is used for measuring flow and pressure on the water inlet pipeline and pressure of water inlets and water outlets of water pumps, and the control system is connected with the power driving system and the measuring system. The multiple water pumps to be measured are separately mounted on the multiple branch pipelines a, every two adjacent branch pipelines a are connected through the branch pipelines b, the two ends of the multiple branch pipelines a are correspondi
