PVA processing temperature fluctuation
Problembeschreibung
During PVA processing, temperature fluctuates ±5-8°C, exceeding the ±2°C control precision
Ursachenanalyse
Improper PID parameters of the temperature control system; aging heater bands, uneven power; improper thermocouple position, measurement deviation
Lösung
1) Re-tune PID parameters; 2) Replace aging heater bands; 3) Adjust the thermocouple position to the melt pool center
Wichtigste Erkenntnis
Temperature fluctuation is caused by an improper temperature control system; PID tuning and heater band replacement are the key
