通过对简易水弧切割枪喷嘴的应用,获得了很好的效果,特别是切口质量有了显著地提高。由于水帘的作用,切口的热影响区大为减小,切口光亮,且不影响切口处的耐蚀性。水帘能使等离子弧收敛,故割缝窄。由于水帘有冲刷作用,这种喷嘴比用普通喷嘴切割的渣少,即使在挂渣较多时,渣也比较疏松,容易清理。应用这种喷水的喷嘴切割时,空气污染明显降低,噪声小。由于枪体的水压减小,故切割枪的漏水现象也有了减少。在LG-400-1型等离子切割机上应用这种特殊喷嘴时发现,由于原水路系统中,水经下
Through the application of simple water arc cutting gun nozzle, get good results, especially the incision quality has been significantly improved. Due to the effect of the curtain, the heat-affected zone of the cut is greatly reduced, the cut is bright, and the corrosion resistance at the cut is not affected. Curtains can make the plasma arc convergence, so cut narrow. As the curtain has the scouring effect, this nozzle than the ordinary nozzle cutting less slag, even in the dross is more, the slag is also relatively loose, easy to clean. When using this water jet nozzle cutting, the air pollution is significantly reduced, the noise is small. Due to the reduction of the water pressure of the gun body, the leakage of the cutting gun has also been reduced. In the LG-400-1 plasma cutting machine application of this special nozzle found that, as the original waterway system, the water through the lower
