CNC water jet cutting machine

What is Water jet cutting machine?The technologies use the principle of pressurizing water to extremely high pressures, and allowing the water to escape through a very small opening (typically called the "orifice" or "jewel"). Water jets use the beam of water exiting the orifice (or jewel) to cut the material.Abrasive jets use that same beam of water to accelerate abrasive particles to speeds fast enough to cut through much harder materialsHow does Waterjet work?The intensifier acts as an amplifier as it converts the energy from the low pressure hydraulic fluid into ultra-high pressure water. The hydraulic system provides fluid power to a reciprocating piston in the intensifier center section. A limit switch, located at each end of the piston travel, signals the electronic controls to shift the directional control valve and reverse the piston direction.The intensifier assembly, with a plunger on each side of the piston, generates pressure in both directions. As one side of the intensifier is in the inlet stroke, the opposite side is generating ultra-high pressure output. During the plunger inlet stroke, filtered water enters the high pressure cylinder through the check valve assembly. After the plunger reverses direction, the water is compressed and exits as ultra-high pressure water and then enters the pressure vessel(accumulator) The accumulator smoothes pressure fluctuations from the intensifier and delivers a constant and steady stream of ultra-high pressure water to the cutting tool.If convey high pressure water into the nozzle directly, the pressure will be unstable. And the pressure will fluctuate periodically. To keep stable high pressure water, one attenuator will be fitted between intensifier and nozzle. Meanwhile one mini oil pump is added to keep water pressure more stable. So that the energy loss is limited within 5% normally.
