Dynamic processes in the pulsation chamber vibration machine for disinfection of water

There is a design of vibrating machine proposed in this paper. In this vibrating machine low-frequency vibrations are used to form cavitation cavities in a liquid substance in order to disinfect it. To study the dynamics of a vibrating machine, an analytical model has been created, which makes it possible to determine the change in the maximum pressure in the working body of a vibrating machine and analyze the influence of drive operating modes and design parameters on the efficiency of the water disinfection process. From the accomplished experimental studies, graphical dependences of the influence of design parameters and drive operating modes on the change in maximum pressure in the working body of a vibrating machine are obtained. Using video, we visualized the processes taking place in the working body of the vibrating machine, and analyzed the occurrence of cavitation phenomena in the working body of the vibrating machine. According to the results of the studies, it is recommended for practical use in vibration machines the frequency boundaries of the drive’s vibrations, the oscillation amplitude, the size of the piston and the holes in it, and their ratio
