Description
Technical Field

Background
The introduction of abrasive particles into the high pressure water forms an abrasive water jet. The introduction of the abrasive particles greatly improves the action effect of the water jet, so that the abrasive water jet can realize rust removal, sand removal and cutting operation under relatively low pressure. The abrasive jet flow equipment needs to utilize a high-pressure generator when in use, so that high cutting efficiency can be achieved, but the speed of pure water cutting is not ideal when the pure water cutting is used for cutting harder materials, which is also the basis of the development of the initial abrasive water jet flow technology. Water cutting, without water-jet sanding, is compromised in both accuracy and depth of cut. Laboratory data show that only 3mm titanium plates can be cut without abrasive discharge and that the cut is jagged. After the water jet cutter sand water cutting abrasive is added, a 30mm titanium plate can be easily cut, and the precision is very accurate. The cutting ability of the abrasive jet is primarily derived from the constant supply of abrasive particles in the jet. If the abrasive supply is cut, the abrasive jet is transformed into a normal water jet, and the material cannot be cut further. It is therefore necessary to know and monitor the supply of abrasive material during the cutting process.
The jet is ejected from the water nozzle and then enters the mixing chamber. Wear of the water nozzles can have a significant effect on the jet characteristics and the subsequent mixing and cutting process. Simultaneously, the collimator accelerates the abrasive particles to a velocity close to that of the water jet; adjusting the abrasive particles in the jet flow to be consistent in direction; the abrasive particles are directed toward the workpiece. During operation, severe friction occurs between the collimator and the abrasive particles, which results in an increase in the inner diameter of the collimator. As an important parameter of the cutting process, the collimator diameter has a direct influence on the depth and quality of the cut. Therefore, the operation and wear of the water nozzle and the operation of the collimator affect the cutting effect.
Therefore, the abrasive supply of the abrasive jet flow is effectively controlled, the state of the abrasive jet flow passing through the nozzle and the collimator is monitored in real time, the abrasive and water can be in a good matching state, the stable using effect of the abrasive jet flow can be guaranteed, and the method has important significance for the application effect of the abrasive jet flow.
