Research Abstract

In this study, a self-spin waterjet nozzle system that has a vane pump for braking rotational speed of nozzle system was proposed, and a prototype of a nozzle system was developed. To clarify the fundamentals on the rotational speed of the nozzle system, a measurement of the rotational speed of nozzle system was conducted. It was clarified that the rotational speed of nozzle system obtained for the nozzle system with the vane-pump type brake system was much smaller than that obtained for the nozzle system without the brake system.
