AI Technical Summary
Existing steam jet mixers exhibit lag in adjusting outlet pressure, failing to respond promptly to changes in downstream steam load, resulting in outlet pressure fluctuations and making it difficult to meet the high-precision pressure stabilization requirements in industrial settings.
By acquiring multi-source data from the steam jet mixer, including the actual values of high-pressure steam inlet pressure, low-pressure steam inlet pressure, and outlet pressure, a quantitative evaluation system is constructed. The dynamic response coefficient of the driving pressure, the sensitivity coefficient of the ejector structure, and the downstream load disturbance coefficient are calculated to generate valve opening adjustment commands and achieve dynamic balance adjustment of the outlet pressure.
It achieves precise pressure regulation of the steam jet mixer outlet pressure, reduces the lag of the control system, and improves the pressure stability and response speed of the steam mixer in industrial scenarios.
