基于ANSYS Workbench对单螺旋榨油机榨膛温度分布情况的研究

Temperature distribution of single screw oil press barrel based on ANSYS Workbench

采用单螺旋榨油机压榨的方式,通过加热装置对榨膛辅助预热实现对油料的预热处理,用红外测温仪得到榨膛外壁测点温度。依据热传导反问题理论,再通过ANSYS Workbench得到榨膛内外壁温度分布情况。对比榨膛外壁实测温度与仿真温度,误差范围在-2.023%~6.274%之间,表明通过ANSYS Workbench可预测榨膛内外壁温度分布。

The single screw press was used to preheat the oil by auxiliary heating of the press barrel by a heating device,and the temperature on the outer wall of the press barrel was measured by an infrared thermometer.Based on the inverse problem theory of heat conduction,the temperature distribution of the inner and outer wall of the press barrel was obtained through ANSYS Workbench.Comparing the measured temperature on the outer wall of the press barrel with the simulated temperature,the error range was between-2.023%and 6.274%,indicating that the temperature distribution on the inner and outer wall of the press barrel could be predicted by ANSYS Workbench.
