水再压缩等离子弧切割是常规的氮气等离子弧切割技术的一个发展,它进一步提高切割质量、效率,并有效地改善了因等离子弧切削所造成的环境污染,改善了工人的劳功条件。喷嘴结构当前实现水再压缩等离子弧切割的方法,大都是在割炬喷嘴之外再加一个由绝缘物质(如页腊石)做成的水喷嘴,由其喷水进一步 The water recompression plasma arc cutting is a development of the conventional nitrogen plasma arc cutting technology, which further improves the cutting quality and efficiency, and effectively improves the environmental pollution caused by the plasma arc cutting, thereby improving the working conditions of workers. The current nozzle structure to achieve water-compressed plasma arc cutting method, mostly in addition to the torch nozzle nozzle made of an insulating material (such as a pyrophyllite) made by the water jet further
