In the machining industry, it has a wide range of applications, because it has strong variability, so it can solve all kinds of complicated problems. Many consumers do not understand the production of waterjets, and believe that the water used for waterjets is free from impurities. No.
It is wrong for water used in waterjets to have no impurities at all. Because the water pressure is much greater than 700 MPa, pure water will always cause them to wear out and leak for sealing equipment such as pipes, no matter how good the sealing performance is. In order to solve this problem, water razor must be added with 5% soluble emulsified oil to improve the sealing effect. For high pressure pumps, add some oil to improve its sealing performance.
Waterjet nozzle is made of hard alloy, sapphire and other materials, the diameter of the nozzle is only 0.05 mm, and the hole wall is smooth, can withstand a pressure of 1700 MPa, so the high-pressure water ejected can cut material like a knife. Some waters also incorporate long-chain polymers, such as polyethylene oxides, which increase the "viscosity" of the water and make the ejected water look like a "thin line."
In order to make the water knife more powerful, it will also add sand in it. The water knife in the sand at home can almost cut off all kinds of materials, and the pressure generated is also very large. Therefore, you must be very cautious when operating.
