摘要
基于日益严格的排放法规对喷油嘴的孔径,孔形,孔的位置度和喷孔的流量系数提出的越来越严格的要求,介绍了喷孔加工的最新工艺手段及相关设备的应用,加工基准的选择,各坐标轴系统的调整要求,K系数倒锥的加工成型,电脉冲电源的设计特点等技术手段,为喷孔加工工艺提供了设计经验。
Increasing stringent emission regulations require more and more strict controlling and high precision of nozzle spray hole,such as hole diameter,shape,position and flow efficiency.This paper introduces the new technical methods and related equipments,including selection of manufacture base,adjustment of each axis,K factor of inverted cone shaping,design features of electrical pulse power supply and so on,thus provide engineering references for spray hole manufacture.
