water jet cutting|water jet cutting process
Water jet cutting processThere are two types of water jet cutting methods: low pressure water jet and high pressure water jet.
Low-pressure water jet cutting is to use high-pressure water (14-69MPa) to pre-mix the cutting abrasive in a pressurized storage tank, and then send the mixed abrasive slurry directly into the cutting gun through a hose for cutting. The workpiece to be cut can be 500m away from the cutting power source. Or cut underwater.
High-pressure water jet cutting is to convey high-pressure water (greater than 240MPa) and dry abrasives through their respective hoses, and then mix them in the mixing chamber of the cutting gun to complete the cutting process of objects, that is, shear and add For n kinds of materials, the workpiece Generally, it is carried out near the cutting power source.
When the low-pressure and high-pressure water jet cutting is cut under the same conditions, the water and cutting abrasive consumption of the former is 1/8 to 1/3 of the latter; from the perspective of the structure of the cutting torch, the low-pressure water jet cutting torch is relatively simple; In terms of energy consumption, low-pressure water jet cutting consumes less energy. Therefore, low-pressure water jet cutting is currently the most effective cutting method.
