Referring to fig. 1 to 5, a deionizer performance testing apparatus according to an embodiment of the present invention includes a first container 110, a second container 120, a first pipe 210, a second pipe 220, a third pipe 230, a water pump 300, and a conductivity detector 400, wherein the first container 110 is used as a main liquid storage device, and is respectively connected to the first pipe 210, the second pipe 220, and the third pipe 230, and is also used as a mixing location for a newly added liquid and an original liquid in the apparatus. The second container 120 is used for replenishing the liquid and also serves as a gas discharge passage for replenishing the liquid in the first container 110. The water pump 300 is used for driving the liquid to flow in the pipeline, and the conductivity detection device 400 is used for detecting the conductivity of the liquid in the pipeline.
Taking the example shown in the figure, the first container 110 has a first inlet 111, a first outlet 112 and a second outlet 113, the first inlet 111, the first outlet 112 and the second outlet 113 all open into the inner cavity of the first container 110, and the second outlet 113 is located at the highest position of the first container 110. One end of the first pipe 210 is connected to the first inlet 111 of the first container 110, and the water pump 300 is connected to the first pipe 210. One end of the second pipe 220 is connected to the first outlet 112 of the first container 110, the other end is connected to the other end of the first pipe 210, and the conductivity detection device 400 is connected to the second pipe 220. In this way, when the deionizer 900 is connected to the second pipe 220, the first pipe 210 and the second pipe 220 form a first circuit, and the first container 110, the deionizer 900, the conductivity detection device 400, and the water pump 300 are connected in series in the first circuit. As the water pump 300 drives the liquid to flow in the first circuit, the deionizer 900 may continuously adsorb conductive ions in the liquid, thereby reducing the conductivity of the liquid. The conductivity detection device 400 measures the conductivity of the liquid, and it should be noted that the conductivity detection device 400 may be disposed at the outlet of the deionizer 900 to measure the conductivity of the liquid processed by the deionizer 900.

As such, the first pipe 210 and the third pipe 230 may form a second circuit in which the first container 110, the water pump 300, and the second container 120 are connected in series. The second container 120 has a liquid pouring port 121, and a liquid or a conductive material (for example, sodium chloride or the like) can be poured into the second container 120 through the liquid pouring port 121, so that the liquid in the first container 110 and the liquid in the second container 120 can be mixed when the liquid is driven to flow through the second circuit by the water pump 300. In summary, under the driving of the water pump 300, the liquid flows in the first circuit and the second circuit simultaneously, and the externally added conductive material diffuses through the first circuit and then diffuses into the second circuit through the first container 110.
It should be noted that the second container 120 is higher than the first container 110, so that at least the inlet of the second container 120 connected to the pipe segment 231 is higher than the second outlet 113.

On the other hand, when the testing device is applied to an automobile fuel cell system, the water tank in the automobile is usually used as the above-mentioned container to be closer to the actual use scene, but the testing device is limited by the space inside the automobile, and the volume of the water tank is usually smaller, so that the water storage requirement of the system is difficult to meet.
