Definitions
- the present invention relates to a device for deburring and / or cleaning a workpiece immersed in a liquid medium, comprising a liquid discharge device for producing a high-pressure-loaded liquid jet.
- Such a device is particularly well suited for deburring and / or cleaning of mechanically, in particular machined, machined workpieces.
- a workpiece By subjecting a workpiece to a high pressure fluid jet, burrs and / or contaminants may be separated from the workpiece.
- the GB 2 078 546 A discloses a device for cleaning underwater structures, such as oil rigs, which comprises a liquid discharge device for generating a high pressure fluid jet and a gas discharge device for generating a gas flow surrounding the liquid jet. Furthermore, the device comprises a recoil jet arrangement, which likewise comprises a liquid discharge device for producing a high-pressure-loaded liquid jet and a gas discharge device for producing a gas stream enclosing the liquid jet.
- the WO 02/44020 A1 discloses a device for cleaning boat hulls submerged in water comprising a liquid discharge device for generating a high pressure fluid jet and a gas discharge device for generating a volume in which the density is lower than in the surrounding water, the high pressure liquid jet being forced through this lower density volume passes.
- the present invention is based on the object to provide a device for deburring and / or cleaning a immersed in a liquid medium workpiece, which is particularly efficient.
- the device according to the invention makes it possible to provide a gas stream which at least partially shields the liquid jet from the liquid medium, so that the friction between the liquid jet and the liquid medium can be considerably reduced. This ensures that the liquid jet during its movement through the liquid medium in the direction of the workpiece is not or only slightly slowed down.
- This has the advantage that a liquid jet generated by the device according to the invention has a higher kinetic energy upon impact with a workpiece surface than is the case with devices known from the prior art. This can the deburring and / or cleaning effect can be improved.
- the liquid jet can be subjected to a lower pressure, whereby the energy consumption of the device according to the invention compared with devices known from the prior art is reduced with identical deburring and / or cleaning action.

- the device according to the invention makes it possible to achieve a high deburring and / or cleaning effect with a low energy input.
- the device according to the invention makes it possible to deburr and / or clean a workpiece with particularly low noise and low emissions.
- the gas flow allows a sound decoupling of the high pressure Liquid jet on the one hand and the liquid medium on the other. With the help of the gas flow also an interaction between the liquid jet and the liquid medium is reduced, so that the formation of a liquid mist can be at least largely prevented. Accordingly, the device according to the invention makes it possible to dispense with external extraction systems or to be able to dimension corresponding extraction systems very small.
