Cooling system efficiency decline of polyolefin plastomer extruders
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 causes the production speed to decrease or the product to deform.
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 circuit is scaled and clogged
（4）The cooling water tank length is insufficient
（5）The product wall thickness is large and 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 circuit 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
핵심 요약
The decline in cooling efficiency is caused by insufficient water volume or excessive water temperature, and the cooling system needs to be improved and the water temperature controlled.
