摘要： An improved mixing tube for use in a high-pressure abrasive fluid jet system is shown and described. In a preferred embodiment, the mixing tube is provided by forming a first piece and a second piece, each piece having a length that is substantially equal to the length of the mixing tube. A longitudinal groove is provided in each piece, the longitudinal groove extending from a first end to a second end of each piece. The first and second pieces are coupled together, such that the first and second longitudinal grooves meet to form a bore that extends longitudinally through the length of the mixing tube. Although the first and second pieces may be joined in a variety of ways, in a preferred embodiment, the two pieces are joined by shrink fitting a metal sheath around the outer surface of each piece. The first and second pieces are made of a hard ceramic material, and the longitudinal grooves are formed by grinding the pieces to remove material along their length. In this manner, any desired geometry of the bore may be achieved by varying the amount of material removed from each piece. To further increase the life of the mixing tube, each of the first and second longitudinal bores is coated prior to being coupled together, the longitudinal grooves being coated using conventional CVD techniques.

摘要： A method for uniformly roughening a surface through use of an ultrahigh-pressure fluid fan jet has been shown and described. In a preferred embodiment, an ultrahigh-pressure fan jet is generated by pressurizing a volume of fluid, and forcing the pressurized fluid through a fan jet nozzle. The fan jet is positioned relative to the surface to be treated at a desired distance, and the fan jet is traversed across the surface at a selected rate to uniformly roughen the surface. In a preferred embodiment, the achieved surface roughness is quantified and compared to a desired surface finish. Operating parameters, such as horsepower and traverse rate, may then be adjusted accordingly to achieve the desired surface finish. By uniformly and completely roughening a surface through use of an ultrahigh-pressure fan jet prior to applying a coating to the roughened surface, adherence between the surface and the coating will be improved.

摘要： A method and apparatus for cutting metal casings with an ultrahigh-pressure abrasive fluid jet is shown and described. Examples of such casings include piles and conductors of offshore oil production platforms. In accordance with a preferred embodiment of the present invention illustrated herein, the apparatus is lowered inside the casing to be cut to a desired depth where it is secured to an inner surface of the casing. An ultrahigh-pressure stream of fluid is forced through a nozzle provided in a jet manifold of the apparatus to produce an ultrahigh-pressure fluid jet, into which a volume of abrasives is entrained, thereby generating an abrasive fluid jet. A drive mechanism is provided to rotate the abrasive fluid jet in a substantially horizontal plane to produce a circumferential cut in the casing. The abrasive fluid jet may also be moved in a vertical plane if necessary to complete the cut, for example if the initial cut is in the form of a helix. The performance of the jet is monitored by listening to the sound intensity of the jet with hydrophones.In accordance with the present invention, the cut in the casing may be made by the abrasive fluid jet in either a water or air environment, an air environment being created in a vicinity of the abrasive fluid jet by displacing a volume of water. The volume of abrasives may be entrained in the ultrahigh-pressure fluid jet by a vacuum created by the jet passing through the nozzle or, in an alternative embodiment, the abrasives may be entrained in a pressurized stream of a low density medium such that the pressurized abrasives are injected into the ultrahigh-pressure fluid jet.

摘要： An assembly for changing the temperature of ultrahigh-pressure fluid as it flows through ultrahigh-pressure tubing includes several thermally conductive blocks. Each block has a first bore through which the ultrahigh-pressure tubing passes, and a second bore containing a source of heating or cooling. Alternatively, resistance heating is used to increase the temperature of the ultrahigh-pressure fluid, by coupling electrodes to the outer surface of the tubing. The ultrahigh-pressure fluid is heated or cooled after it is pressurized, and is then discharged from the ultrahigh-pressure tubing at a selected temperature for use. For example, the ultrahigh-pressure fluid at a selected temperature may be discharged through a nozzle to form an ultrahigh-pressure fluid jet to cut or clean any desired surface or object, or it may be discharged to a pressure vessel to pressure treat a substance.

摘要： Improved methods and apparatus for pressure processing of pumpable substances are shown and described. In one embodiment, the apparatus includes an inlet valve, an outlet valve, and a pressure vessel. The inlet valve has an inlet port, and is coupled to a source of a pumpable substance and to the pressure vessel. The outlet valve has an outlet port and is coupled to the pressure vessel. When the inlet valve is opened and the outlet valve is closed, a volume of pumpable substance may flow into the pressure vessel. The inlet valve is then closed and the outlet valve remains closed, and the pumpable substance within the pressure vessel may be pressurized to a selected pressure for a selected period of time. The outlet valve is then opened, allowing the pumpable substance to be discharged. In an alternate embodiment, the apparatus may include at least one aseptic valve assembly having elements which cooperate to apply cleansing solution to one or more surfaces, the surfaces having the potential of being contaminated. The cleansing solution may be applied to the surface by cleansing chambers or by nozzles.

摘要： A method and apparatus for biasing a seal assembly in a high pressure fluid pump. In one embodiment, the fluid pump includes a reciprocating plunger, a seal carrier disposed about the plunger, and a seal supported by the seal carrier and sealably engaged with the plunger. The seal may be biased toward the seal carrier with a spring and may include a flange that engages the spring to restrict lateral motion of a spring relative to the reciprocating plunger. The flange may engage an inner and/or an outer surface of the spring. Where the spring is a coil spring, the flange may be continuous around the circumference of the spring or may include a plurality of spaced apart projections located around the circumference of the spring.

摘要： A coupling for a high pressure fluid seal assembly is shown and described. The coupling includes a first member having first and second opposite ends and capable of motion along a first axis extending between the first and second ends. The first member has an engagement portion positioned toward the first end having a rounded convex engagement surface. The coupling further includes a second member also having first and second opposite ends and capable of motion along a second axis extending between the first and second ends of the second member. A second engagement portion toward the second end of the second member has a substantially flat second engagement surface engaging the first engagement surface of the first member. The interface between the first and second engagement surfaces aligns motion of the first member along the first axis with motion of the second member along the second axis. The coupling accordingly reduces the tendency for either the first or second member to bend. The coupling assembly further reduces the tendency for the first and second members to move laterally relative to their respective longitudinal axis.
