PESU Hopper Drying Requirements
Problembeschreibung
PESU hopper drying with insulation and sealing, inlet air temperature and dew point control.
Ursachenanalyse
PESU hopper drying requires sufficient insulation and minimal leakage; inlet air temperature maintains pellets at 135℃; dew point -40℃; sufficient time; uniformity.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Lösung
①Hopper insulation and sealing; ②inlet air temperature monitoring; ③dew point detection; ④time guarantee; ⑤uniformity verification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
PESU hopper drying is a common method; condition control is the key to effectiveness; monitoring ensures quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
