Background

The water jet is a high-speed water flow stream of different shapes formed by the outflow of a nozzle, and the flow speed of the water jet depends on the pressure drop before and after the outlet section of the nozzle. Generally, a power-driven pump pumps a certain amount of water to a high-pressure pipeline by performing a suction and discharge process on the water, so that the water reaches a nozzle with certain energy. The nozzle aperture is required to be much smaller than the high pressure line diameter, so that the amount of water reaching the nozzle must be accelerated to exit the nozzle orifice. The water accelerated through the nozzle orifice thus condenses to form a jet. The abrasive jet refers to a jet formed by abrasive moving at high speed after the abrasive is accelerated under the action of some external power. In the traditional abrasive water jet equipment, water is used as a medium, after the medium obtains huge energy through high-pressure generating equipment, the abrasive is directly injected into the high-pressure water through a feeding device, and the abrasive is jetted from a nozzle at a high speed in a specific fluid motion mode to form a strand of abrasive water jet with concentrated energy at a high speed.
