Cooling system efficiency decline of low density polyethylene extruder
Sorun Belirtisi
Insufficient product cooling; temperature still high after exiting the cooling water tank, affecting sizing effect and subsequent cutting.
Cooling efficiency decline causes reduced production speed or product deformation.
Neden Analizi
(1) Insufficient cooling water flow or low water pressure
(2) Cooling water temperature too high
(3) Cooling water channel scaling and blockage
(4) Insufficient cooling water tank length
(5) Large product wall thickness, slow heat dissipation
Çözüm
(1) Check cooling water pump and pipes, ensure sufficient flow and water pressure
(2) Add cooling water chilling device (chiller), control water temperature 15-25°C
(3) Regularly clean cooling water channels and cooling water tank, remove scale
(4) Increase cooling water tank length or add cooling stations
(5) Appropriately reduce extrusion speed for thick-wall products, extend cooling time
Temel Çıkarım
Cooling efficiency decline is caused by insufficient water volume or excessive water temperature; the cooling system needs improvement and water temperature control.
