通过实验对自振脉冲磨料水射流切割过程中部分因素对切割性能的影响关系进行了研究,得出了靶距、切割次数、横移速度、系统压力同切割性能的影响关系,并对自振脉冲磨料水射流用于矿井切割的安全性进行了分析论证,得出该方法切割温度低、火花持续时间极短,不会引起瓦斯爆炸的结论,表明该切割方式用于井下安全切割是可行的。 The influence of some factors on the cutting performance during the cutting process of self-oscillating pulsed abrasive water jet was studied experimentally, and the relationship between cutting distance, target distance, cutting frequency, traverse speed and system pressure was obtained. The results show that this method has the advantages of low cutting temperature, very short duration of spark and no gas explosion. It shows that the cutting method is feasible for safe cutting in underground mine .
