The classification of the waterjet cutting machine
According to the abrasive: waterjet cutting machine is divided into no sand cutting and abrasive cutting.
According to equipment: divided into large water cutting and small water cutting.
According to pressure: divided into high pressure and low pressure, bounded by 100mpa. Above100mpa for high pressure type, below 100mpa for low pressure type. And above 200mpa for ultra high pressure type.
According to the technical principle: divided into pre-mixing type and post-mixing type..
According to the mechanical structure: divided into cantilever and gantry type
According to safe cutting: divided into safe cutting class and not safety cutting class, The difference is mainly in water pressure, 100MPa below low pressure water cutting can be used in special industries such as such as: danger, petroleum, coal mine, dangerous material, etc. Through a large number of experiment it was found that, even though the pure water detonates some sensitive chemicals when the water pressure exceeds a certain threshold, and due to abrasive sand in water, sand of potential energy and the impact and collision of s can also cause the instability of special chemicals,After a lot of experiments and demonstration, finally it is concluded that the threshold is about 237.6MPa. Therefore, in the waterjet cutting industry, waterjet cutting above 200MPa is mainly used in the mechanical processing industry.
