High pressure water jet device, channel cleaning device and high pressure water jet method

摘要

The invention relates to a high-pressure water jet device for treating a surface. For this purpose, the high pressure water-jetting device comprising a nozzle (2) having at least one opening (21) for generating a beam (3) of a liquid, under high pressure medium. The invention further relates to a duct cleaning apparatus for cleaning a channel (11) comprising avoid high pressure water jet apparatus and a high-pressure water jet method for processing a surface by means of a beam (3) of a liquid, under high pressure Mediums.Um damage to the surface due to the treatment to obtain and applicability for the designated application and to improve, it is proposed the jet after leaving the nozzle (2) and to deflect prior to impinging on the surface to be machined by means of a beam deflection (4), which in the beam a by means of a Strahlumlenkmittelpositionierungseinrichtung (5) is positionable toward and positionable to the opening in the beam path Strahlumlenkfläche (41).
