Optimization Design for Cooling Channel of the Single Screw Extruder Barrel

Abstract

To solve the issue of machine barrel skewed to one side, when the XJ150×25 was running. Under the conditions that the needs of strength was met, by designed three types of cooling channels and analyzed the temperature field for the barrel by using ANSYS, as well as thermal deformation. The results show that cooling channel of center symmetric form can solve the problem that uneven temperature field causing the barrel to produce thermal deformation. It can guarantee the coaxial degree between screw and barrels and can improve the quality of products.
