Waterjet nozzle is an important water jet spare parts of waterjet cutting equipment. Its function is to pass high-pressure water flow through a certain-shaped aperture to form a high-speed, high-energy water jet for cutting various materials. There are several types of waterjet nozzles:

Pure water cutting nozzles, also called liquid column nozzles, only use high-pressure water flow for cutting, and are suitable for cutting soft materials such as paper, textiles, rubber, and plastics. Pure water cutting nozzles are generally made of hard materials such as rubies, artificial gemstones or diamonds, to ensure the wear resistance and precision of the nozzles.

Abrasive water cutting nozzles, also known as mixed flow nozzles, add garnet sand and other abrasives to high-pressure water flow to form high-speed, high-energy water-sand jets for cutting hard materials such as metals, ceramics, and glass. Abrasive water cutting nozzles are generally composed of two parts: one of the water jet spare parts is a water jet nozzle, and the other water jet spare parts is a sand tube or a sand mixing chamber. The water jet nozzle is the same as the pure water cutting nozzle, while the sand pipe or sand mixing chamber is generally made of wear-resistant materials such as tungsten steel, tungsten carbide or hard alloy. There is also a fan-shaped nozzle related to water cleaning, also called an atomizing nozzle, which passes high-pressure water flow through a flat aperture to form a fan-shaped atomized water flow for cleaning, cooling, wetting and other processes.

Fan nozzles are generally made of corrosion-resistant and wear-resistant materials such as stainless steel, tungsten steel or tungsten carbide.

The maintenance methods of waterjet nozzles are as follows: Regularly check whether the inner hole of the nozzle is worn, deformed or blocked, and replace the damaged or invalid nozzle in time. Select the appropriate working parameters and modes to avoid exceeding the rated pressure and flow of the nozzle, and prevent the nozzle from being overloaded or damaged. When storing and transporting nozzles, pay attention to moisture-proof, dust-proof, shock-proof, and pressure-proof to avoid damage to the nozzles by external forces or environmental influences
