磨料水射流多细孔加工液压系统的参数计算及实现

The Algorithm and Realization of the Hydraulic System for Manufacturing Multi-pores by Abrasive Water Jet

论述了磨料水射流加工的相关机理,提出了不需喷嘴,直接通过流经多细孔的流体与孔壁的作用而进行加工的思路,指出了加工中的4个关键因素,即流体速度、流体状态、系统流体状态分布以及磨料粒度。确定了系统参数配置方案,以主管程为突破口进行参数配置,在主管程参数配置已到极限的情况下,再启动旁路管程进行参数配置,最终达到参数最优化。最后以一个实例给出了液压系统参数设计的详细过程。

The related mechanism of the abrasive water jet （AWJ） was elaborated, the idea of manufacture by the action of fluid that AWJ flows through the multi-pores and pore wall was proposed, the four key aspects in the manufacture process, namely： fluid velocity, fluid condition, fluid condition distribution in the system and abrasive size were pointed out. The plan of configuring system parameters was determined, it is to configure the main pipe parameter at first, then to configure the breach pipe parameter when the main pipe parameter can not be adjusted, the parameter optimization is made. An example was given to explain the detailed process of designing hydraulic system parameters.
