AI Technical Summary
In existing water purifier performance tests, the automatic solution preparation system lacks an online monitoring and feedback correction mechanism for the actual effluent water quality, causing the solution preparation to deviate from the target indicators and affecting the accuracy and reliability of the test results.
By real-time monitoring of conductivity, pH value, and combined indicators, the flow rate of the standard solution is adjusted to achieve online correction of the water quality of the test water, ensuring that it is within the target index range. The mixing ratio of the standard solution and pure water is controlled by metering pumps and regulating valves.
It improves the accuracy of drug solution preparation, enhances the accuracy and efficiency of water purifier performance testing, reduces manual intervention, and achieves automated and continuous operation processes.
