What should I do if the temperature control system is always slow to respond and laggy? At the site, waste water is indirectly heated using a heat exchanger; once the temperature reaches the set value, the steam valve is adjusted. In fact, the temperature is already above the process set value, resulting in a delay. What should be done?
Temperature control regulation involves lag; control valves for automatic temperature control require the use of differentiation. We have switched our temperature control to manual or flow-controlled mode. When making adjustments, don’t rush; be patient and wait. Make small adjustments at a time, rather than making continuous changes.
Excuse me, sir, what does flow control mean?
PID has a self-tuning function; give it a try
Sir, what is the self-tuning function, and can it solve the problem of temperature control lag?
The solution is: 1. Improve the PID tuning of the control instruments. 2. It is the adjustment of the process pipeline. The key is the installation location of the control valve
