摘　　要：为了提高高压水射流清洗技术在聚合釜清釜中的除黏效果,对其关键核心部件—高压水射流用三维旋转喷头进行了研究设计及运动学仿真分析。首先结合行星轮系传动原理对其传动方式进行了设计并形成了总体方案及具体结构,然后结合机械端面动密封技术对其密封方式进行了设计及功耗计算,采用磁力限速方式实现了喷头的转速控制,并结合电势平衡原理构建了喷头自旋转转速的稳态计算方程,得到了调整喷头转速的理论方法,最后采用ADAMS软件完成喷头的动力学仿真,验证了设计可行性。研究结果表明:该设计能够满足在设定条件下实现既定转速下的三维旋转动作完成清洗,其为三维旋转喷头的工业化方案实施提供了可靠的理论支撑。To enhance the de-adhesion effect of high-pressure water jet to clean polymerization kettle,a study and kinematic simulation analysis are conducted on its key component-3D rotating nozzle.Firstly,the transmission mechanism is designed based on the planetary gear system principle,resulting in a comprehensive scheme and detailed structure.Secondly,a mechanical face dynamic sealing technology is employed for sealing design and power consumption calculation.A magnetic speed limiting method is implemented for rotational speed control of nozzle.An equation for steady-state rotation speed calculation using the electrostatic balance principle is derived,providing a theoretical foundation for adjusting the nozzle speed.Finally,the dynamics of the nozzle are simulated using Adams software,validating the design feasibility.The study outcomes demonstrate that this design enables the nozzle to perform 3D rotations at the desired speed under specified conditions,offering a reliable theoretical support for industrial implementation of 3D rotating nozzles.
