LLDPE film melt pump pressure stabilization
Fenómeno do problema
Melt pressure fluctuation caused thickness instability; stabilized after installing a melt pump.
Análise das causas
LLDPE high-viscosity melt pressure fluctuations are amplified; the melt pump isolates screw pulsation and provides stable output.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solução
①Evaluate installing a melt gear pump; ②closed-loop pressure control after the pump; ③match pump speed with output; ④regularly maintain the pump body.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Conclusão principal
The melt pump is an effective investment for high-precision LLDPE film production; pressure stabilization directly converts into thickness stability.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
