Large current fluctuation of PVA extruder
Sorun Belirtisi
During PVA extrusion, main motor current fluctuates ±15-20%, affecting extrusion stability and product quality
Neden Analizi
Unstable feeding amount; PVA melt viscosity sensitive to temperature, temperature fluctuation causes large viscosity changes; unsuitable screw structure causes uneven melting
Çözüm
1) Loss-in-weight feeder for stable feeding; 2) Precision temperature control ±1°C; 3) Select a dedicated screw; 4) Increase screw mixing section to ensure uniform melting
Temel Çıkarım
Current fluctuation is caused by unstable feeding, poor temperature control and unsuitable screw; system optimization is the key
