Precautions for high-pressure water jet abrasives for water cutting machines

The high-pressure waterjet of the waterjet cutting machine is divided into two channels before the abrasive tank, and one way enters the abrasive tank through the conditioning valve, and is initially mixed with the abrasive in the tank into a fluidized state and then enters the mixing chamber through the stop valve; high-pressure water jet cutting machine manufacturer In other words, the other way directly enters the mixing chamber and stops the abrasive fluid flowing out of the tank from mixing sufficiently to form a liquid-solid two-phase flow. In this way, the mixing effect of the abrasive and the aqueous medium is enhanced, so that the abrasive particles are sufficiently accelerated in the aqueous medium, so the abrasive particles have extremely high kinetic energy.
However, the calculation of the cost of the use of these accessories is also based on the actual situation. For example, our company's customers report that the use time of waterjet cutting gemstones varies, sometimes the use time is very long, and some time is very short. The fastest one is broken in 3 hours, and some waterjets need to be replaced after 30 hours. Based on our experience, it may be related to the following points.
1. It can easily cut stainless steel plates or hard marble, granite, etc., and it is very ideal or unique for processing materials that are difficult to cut due to other methods, such as aramid, titanium alloy and other composite materials;
2. There will be no cracks when cutting, and it can cut materials with very narrow gaps. Generally speaking, the cut of pure water cutting is about 0.1mm to 1.1mm, and the cut of sand cutting is about 0.8mm to 1.8mm. As the diameter of the inner hole of the sand nozzle expands, the incision becomes larger;
3. It can be cut in all directions, including various shapes, angles or slopes;
4. There is no need to stop secondary processing such as edging, and it can also reduce fly dust during the cutting process and improve the working environment.
