Cooling system efficiency decline of general-purpose polyethylene extruder
문제 현상
The product is insufficiently cooled, and the temperature is still high after leaving the cooling water tank, affecting the sizing effect and subsequent cutting.
The decline in cooling efficiency leads to reduced production speed or product deformation.
원인 분석
（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 channel is scaled and blocked
（4）The cooling water tank length is insufficient
（5）The product wall thickness is large and the heat dissipation is slow
해결 방법
（1）Check the cooling water pump and water pipes to ensure sufficient flow and water pressure
（2）Add a cooling water cooling device (chiller) and 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）For thick-walled products, appropriately reduce the extrusion speed and extend the cooling time
핵심 요약
The decline in cooling efficiency is caused by insufficient water volume or high water temperature, and the cooling system needs to be improved and the water temperature controlled.
