However, the rotating speed is uncontrollable, influenced by high pressure water pressure and water resistance, and simultaneously influenced by the distance between the cavitation cleaning disc and the surface of the ship, if the surface of the ship is uneven, a welding seam exists on the surface, or the heights of pollutants attached to the surface of the ship are different, the rotating speed of the nozzle of the cleaning disc can be influenced, and the rotating speed influences the amount of high-pressure cavitation water erosion on a cleaned target point in unit time, so that the cavitation cleaning effect is influenced. In the design of cavitation cleaning discs, there are typically multiple sets of nozzles, and the increased water volume in the nozzles reduces the time between flushes, but results in a reduced pressure being dispensed to each nozzle. The number of nozzles cannot be increased infinitely, and in practice, 2 or 4 nozzles are the more common form
