| 摘 要： | 运用ANSYS/CFX软件对带行星轮同轴变速单螺杆挤出机流道进行分析，并与普通单螺杆进行对比。结果表明：相较于普通单螺杆，新型同轴变速单螺杆挤出机的建压能力更好，物料在螺杆中的停留时间更长，有利于物料更好地混合，表明带行星轮同轴变速单螺杆可局部降低物料运输速度，增加物料混合能力以及螺杆建压能力。

| Abstract: | Use ANSYS/CFX software to analyze the flow channel of a coaxial variable speed single-screw extruder with planetary gears, and compare with the ordinary single screw. Results: compared with the ordinary single screw, the new coaxial variable speed single screw extruder has better pressure building capacity and longer residence time of the material in the screw, which is conducive to better mixing of the material, indicating that the planetary gear is coaxial. The variable speed single screw can locally reduce the material transportation speed, increase the material mixing capacity and the screw pressure building capacity. |
