摘要： The invention provides a nozzle (2) for abrasive waterjet cutting. The nozzle (2) comprises: a body (4) comprising an outer surface (6); a passage (8) through the body, said passage comprising: in inlet section, an outlet section and a passage direction (14), said passage being configured for guiding an abrasive waterjet. A resistive strain gauge sensor (20) comprises a sensitivity direction (22) along the passage direction. The outer surface is circular and presents a planar area (40) for the sensor which is connected by a Wheatstone bridge. The invention also provides an abrasive waterjet nozzle manufacturing method. The invention also provides a use of a strain gauge sensor attached to a nozzle for abrasive waterjet cutting, for measuring bending vibrations.

摘要： An abrasive water jet cutting machine including pumping means, which can be fluidically connected to a water source, for the generation of a pressurized water flow; a cutting head, forming a mixing chamber and a focusing nozzle; a dispensing system of powdered abrasive material, including a tank containing powdered abrasive material, a feeding pipe, fluidically connecting the tank to the mixing chamber of the cutting head, a dispenser, which dispenses the powdered abrasive material contained in the tank into the mixing chamber by means of the feeding pipe; wherein the pressurized water flow originating from the pumping means is conveyed into the mixing chamber of the cutting head where the pressure energy of the pressurized water flow is converted into kinetic energy so as to form a water jet; wherein the cutting head mixes, in the mixing chamber, the abrasive material with the water jet forming a water-abrasive material mixture jet, and the cutting head dispenses the water-abrasive material mixture jet by means of the focusing nozzle; wherein the powdered abrasive material contained in the tank is homogeneously dispersed in suspension in a gelatinous water-based fluid; and wherein the mass ratio of the dispersed powdered abrasive material to the gelatinous water-based fluid is from 1.0 to 3.5.

摘要： A cavitation nozzle is disclosed, including a plate, a hollow body, and a cap removably engaged with the hollow body and holding the plate against a distal end of the hollow body. The plate may have a central aperture and a distal surface, wherein the distal surface is bisected by a groove and the hollow body is configured to deliver high pressure fluid through the central aperture. The delivered high pressure fluid may be discharged as a cavitating jet.

摘要： Methods of cleaning flow path components of power systems, and sump purge kits used in the same or related methods are disclosed. A method of cleaning may include removing a casing of the turbine system to expose a rotor of the turbine system, a plurality of flow path components coupled to the rotor and/or the casing, and a sump system in communication with the rotor. The method may also include pressurizing the sump system in communication with the rotor, and sealing a plurality of openings formed in the rotor. Additionally, the method may include exposing the rotor and the plurality of flow path components to steam to dry hydrocarbons formed on a surface of the rotor and a surface of the plurality of flow path components, and blasting the rotor and the plurality of flow path components with solid carbon dioxide (CO2) to dislodge the dried hydrocarbons.

摘要： A method of cavitation peening may include coupling a moveable water source to a portable nozzle, through a flexible conduit. The method may include positioning the nozzle adjacent a treatment surface and discharging a first and second stream of fluid through a first and second channel of the nozzle, with the second channel concentrically positioned around the first channel. The first stream may have a first pressure, and the second stream may have a second pressure, the first pressure being greater than the second pressure and the two streams combining to generate a cloud of cavitation bubbles.

摘要： A shroud assembly fixed to an abrasive blasting nozzle provides acoustic dampening during operation of the blasting system to reduce damage to the hearing of the user. The shroud assembly additionally provides features that improve safety and reduce fatigue during use. A first embodiment includes an end closure made up of flat acoustic panels and an alternate embodiment includes an end opening having peripheral chevron shaped acoustic panel edges. The shroud assembly includes a mechanism for attachment of the shroud to the abrasive blasting nozzle, a cylindrical blast column positioned forward from and coaxial with the blast nozzle, a cylindrical cone shell with at least one layer of acoustic dampening material surrounding and coaxial with the cylindrical blast column, a dead man switch handle, a second extended handle, a peripheral air curtain generator at the forward opening, and nested layers of one or more types of acoustic material(s).
