Cooling System Efficiency Decline of Polypropylene Extruder
Sorun Belirtisi
The product is insufficiently cooled, and the temperature is still high after exiting the cooling water tank, affecting the sizing effect and subsequent cutting.
The decline in cooling efficiency leads to reduced production speed or product deformation.
Neden Analizi
(1) The cooling water flow is insufficient or the water pressure is low
(2) The cooling water temperature is too high
(3) The cooling water channels are scaled and blocked
(4) The cooling water tank length is insufficient
(5) The product wall thickness is large, and heat dissipation is slow
Çözüm
(1) Check the cooling water pump and water pipes to ensure sufficient flow and water pressure
(2) Add a cooling water cooling device (chiller) to control the water temperature at 15-25°C
(3) Regularly clean the cooling water channels and cooling water tank to remove scale
(4) Increase the length of the cooling water tank or add cooling stations
(5) Appropriately reduce the extrusion speed for thick-walled products to extend the cooling time
Temel Çıkarım
The decline in cooling efficiency is caused by insufficient water volume or excessive water temperature; the cooling system needs to be improved and the water temperature controlled.
