Ultra-high pressure water jet cleaning system

摘要

An object of the present invention is the provision of optimal ultra-high pressure water jet cleaning system such as an aluminum fin cleaning. A system 1 is provided with a water jet pump equipment 10, and a water jet gun 30 having a rotary nozzle 40 of the air drive, in particular, the rotary nozzle 40, a nozzle head which is rotated, the nozzle head a consist from its center of rotation to the tip and a plurality of nozzles are mounted at different distances in the radial direction, the magnitude of the number of nozzles and the injection hole, the rotational speed of the nozzle head, as well as mutual combination adjustment of the pressure of the ultra-high pressure water Accordingly, it was to be injected while rotating in a spiral shape from the rotary nozzle 40 by an ultra high-pressure water mist. .BACKGROUND
