The principle of water jet technology
The ordinary water is pressurized to a very high pressure (200-400MP) through the pressurizing equipment, and then the high-pressure water is sprayed out through a small hole to form a high-speed jet (water jet), and the speed of this high-speed jet can reach about 800- 1000m/S, because the jet has extremely high kinetic energy, it can quickly erode the object, and if there is relative movement between the jet and the object, it can cut the object. Pure water jet can directly cut soft base materials such as rubber, plastic, leather, etc. If granular abrasive is added to the water jet, the abrasive in the jet is like a "bullet" shot at high speed, which will further increase the The energy of the jet enhances the "destructive power" of the jet, so that it can cut almost any material such as metal, stone, ceramics, glass, etc. This cutting method is called water jet abrasive cutting (also called sand cutting), referred to as water. Knife. Combined with CNC machine tool technology and CAD/CAM technology, the nozzle can move according to the set trajectory, and the workpiece with arbitrary curves and curved surfaces can be cut and processed.
The main components of booster equipment: hydraulic oil circuit system, water supply system, booster, high pressure accumulator, oil cooling device, etc.
