AI Technical Summary
In existing liquid abrasive flow processes, it is difficult to maintain a uniform distribution of abrasive media in the fluid medium, resulting in a smaller distribution of abrasive media in the upper fluid medium and a larger distribution of abrasive media in the lower fluid medium. This also easily causes pipe blockage, and manual timed stirring has limited effect.
The system employs a circulating liquid circuit consisting of an outlet pipe, a circulating pump, and an inlet pipe, combined with a circulating nozzle structure featuring a three-way connector and a nozzle. The circulating pump powers the fluid mixture to form a continuous circulation within the working liquid tank, and the mixture is then evenly sprayed to different areas through the nozzle in a spraying manner, maintaining a uniform distribution of the abrasive media.
It effectively avoids the precipitation of abrasive media in the fluid medium, maintains the uniform distribution of abrasive media in the fluid mixture, improves the uniformity of the fluid mixture, prevents pipeline blockage, and facilitates monitoring and cleaning through the observation window and flushing port.
