Technical Field
The invention relates to the technical field of automatic online labeling, in particular to an automatic online labeling water purification filter element test line and a labeling method.

The pollutant removal index of the domestic water purification filter element is generally evaluated by adopting a pollutant point-plus-standard test method. Namely, after a specified amount of tap water is led into the filter element, a water sample with specified concentration of pollutants is prepared to pass through the filter element, and the pollutant removal capacity of the filter element at the point is tested. However, the method cannot accurately evaluate the actual performance of the filter element when the filter element works in a water sample containing pollutants. The U.S. NSF53 standard provides a test method for evaluating the contaminant removal capacity of a water purification cartridge. In the standard, an aqueous solution of a pollutant with a specified concentration is prepared in a mixing tank, and then the added standard water passes through a test unit through a pump, a pressure regulating valve, a flowmeter and other components. And was run at 50% time, 50% off time, with each session lasting 15-40 minutes, with the cycle being run every 24 hours for 16 hours.
