前混合磨料射流技术是近十几年迅速发展起来的新型射流技术。前混合磨料射流中以水为介质 ,磨料先和水在高压输入管中均匀混合成磨料浆液 ,然后经磨料喷头喷射形成磨料射流。前混合方式加强了磨料和水介质的混合效果 ,使磨料粒子在水介质中得到充分的加速 ,因此 ,前混合磨料射 The former mixed abrasive jet technology is a new type of jet technology that has developed rapidly in recent ten years. Before mixed abrasive jet to water as the medium, the first abrasive and water in the high-pressure input pipe uniformly mixed into abrasive slurry, and then by the abrasive nozzle jet to form abrasive jets. Pre-mixed mode to enhance the mixing effect of abrasive and aqueous medium, the abrasive particles in the aqueous medium to be fully accelerated, therefore, the former mixed abrasive shot
