Tungsten Carbide Waterjet Classification
Divided by the situation of Gaza: water cutting is divided into two methods: no sand cutting and Gaza cutting.
Divided by equipment: divided into large-scale water cutting and small-scale water cutting.
Divided by pressure: divided into high-pressure type and low-pressure type, generally with 100MPa as the limit. High pressure type above 100MPa, low pressure type below 100MPa. And more than 300MPa is ultra-high pressure type.
Divided by technical principles: divided into pre-mixed and post-mixed.
Divided by safe cutting: divided into safe cutting and non-safe cutting, the difference is mainly above the water pressure, low-pressure water cutting below 100MPa can be applied to special industries such as: hazardous chemicals, petroleum, coal mines, hazardous materials processing, etc. After a lot of experiments, people found that when the water pressure exceeds a certain threshold, even pure water will detonate some sensitive chemicals, and sand-containing water cutting. Because the water contains abrasive sand, the potential energy of the sand collides with the impact force and the object. The energy generated will also cause the instability of special chemicals. After a lot of experiments and demonstrations, the threshold is finally around 237.6MPa. Therefore, in the water cutting industry, people mainly apply water cutting above 200MPa in the mechanical processing industry.
