摘要
利用国产高压水射流切割系统 ,对不同性质的材料进行了切割实验 ,考察了泵压、喷嘴横移速度、喷距和聚丙烯酰胺质量分数对射流切割效果的影响。实验结果表明 ,射流的驱动泵压与其切割深度成正比 ,喷嘴横移速度和喷距增加将使切割深度降低。聚丙烯酰胺对射流切割系统具有双重作用 ,因而其质量分数存在一个最佳值。对大理石、花岗岩和标准铝板等材料的切割实验表明 ,在其他实验条件一定的情况下 ,无孔隙材料的切割深度远低于有孔隙材料。
Water jet cutting experiment on different kinds of target materials was conducted at super-high pressure using a domestic super-high pressure water jet cutting system. The influences of the pressure of jet pump, transverse speed of nozzle, standoff distance and mass concentration of additive polyacrylamide on the cutting efficiency of water jet were investigated. The results show that the cutting depth increases proportionally with the pressure of jet pump and decreases as increasing the standoff distance of jet nozzle or the transversely moving speed of jet. Polyacrylamide injected to water jet has dual effects on the jet cutting system. So there is an optimum mass concentration of polyacrylamide to get the highest cutting depth. The cutting experiment on marble, granite and standard aluminum plate under the same experimental condition shows that the cutting depth of non-porous material is much lower than that of porous material.
