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