Summary:The utility model discloses a device for testing flow performance of an oil pump, which comprises an air source (11), a voltage adjusting valve (9), a first pressure sensor (8), an electromagnetic valve (7), a sonic nozzle (6), a second pressure sensor (5) and a communication pipeline, wherein the air source (11) is sequentially communicated with the voltage adjusting valve (9) and the electromagnetic valve (7) by the communication pipeline and then is communicated with one end of the sonic nozzle (6), the other end of the sonic nozzle (6) is communicated with the oil outlet of an oil pump (4) to be tested, the oil inlet of the oil pump (4) to be tested is communicated with air, the first pressure sensor (8) is connected between the voltage adjusting valve (9) and the electromagnetic valve (7), and the second pressure sensor (5) is connected between the sonic nozzle (6) and the oil outlet of the oil pump (4) to be tested. By adopting the structure, the needed test time is very short, so that the cost can be r
