摘　　要：为了有效控制喷头转速,保证高压水射流具有良好的打击性能,对高压水射流用的喷头进行了专门的研究,设计出了一种结构新颖、转速可调的可调式电磁制动自旋转水射流喷头。该喷头克服了其他形式自旋转喷头的缺点,通过改变磁场覆盖比例,达到了喷头转速可调、钻孔速度快及成型规则等效果。通过室内试验,可调式电磁制动自旋转水射流喷头对不同的靶材,不仅转速可调,同时也起到钻孔、切割靶材扩孔的作用,并克服了传统喷头转速高、噪声大、射流雾化严重的缺点,达到了预期效果,有很好的应用前景。In order to effectively control the nozzle speed, high-pressure water jets ensure a good hit performance with high-pressure water. By studying devised a novel structure, adjustable speed adjustable rotating jet nozzle of automatic rotating water electromagnetic brake. The nozzle overcomes the shortcomings of other forms of self-rotating nozzles, by changing the magnetic covering ratio field to achieve a speed adjustable nozzle effect. Through rotating water jet nozzles since different targets, not good drilling, laboratory tests, electromagnetic brake adjustable only do the speed is adjustable, also played a very cutting target reaming role. And overcome the traditional nozzle high speed, noise, jet nebulizer serious drawback to achieve the desired results.It has a good applied prospect.
