Embodiment 1
[0018] Such as figure 1 As shown, a test system for a micro-flow and small-load water pump includes a measurement and control system 1, a metering container 2, a water tank 3, a test pump 4, a flow measurement device 9 and a pressure source 10;
[0019] The water tank is communicated with the inlet of the test pump, and the outlet of the test pump is communicated with the metering container, and the metering container is also communicated with the pressure source, and the pressure source is used to simulate the outlet pressure environment of the test pump, and the metering container is equipped with a flow test device. For measuring the outlet flow rate of the test pump, the measured water is discharged from the outlet of the metering container; the liquid level of the water tank is higher than the level of the test pump, so that the liquid level of the water tank forms a drop L with the test pump; The test system receives the flow data measured by the control flow measuring d...
