AI Technical Summary
Traditional dosing systems have low control accuracy and rely on manual adjustment, which cannot achieve the static accuracy requirement of ±0.5%. PID control will cause dosing to lag when the water inlet flow changes suddenly. Blockages and leakage anomalies require manual investigation, and delayed response leads to production interruptions and safety accidents.
The intelligent valve system is used to achieve closed-loop control through real-time multi-source sensor data acquisition, preprocessing and standardization, combined with PID control algorithm and feedforward compensation, to detect flow mutations and perform feedforward compensation, real-time fault diagnosis and graded response, and dynamic adjustment of PID parameters and control mode.
The static accuracy of dosing amount is ≤±0.5%, the dynamic tracking accuracy is ≤±1%, the blockage detection accuracy is ≥99.7%, the leakage response time is ≤200ms, the unplanned downtime is reduced by more than 80%, and the adaptability of control parameters is improved.
