Abstract
A fluid jet system providing a hydraulic induction manifold for at least two valves. The manifold is positioned “upstream” of an abrasives holding tank, so that no abrasive material flows through the valves and the manifold. The valves and the manifold provide pressurized fluid for at least two different flows: (1) a primary fluid flow and (2) an abrasive material flow through the abrasives holding tank. The two flows are merged again at a junction to provide a fluid flow having a predetermined abrasive-to-fluid mixture ratio. The manifold balances the pressure of the two different flows using a preset geometric relationship between the two different output flow paths associated with the valves.
Claims21
A fluid jet system comprising:
- a fluid jet assembly comprising a lance including a lance barrel;
- a nozzle and a placement structure positioned coupled to the lance barrel at a distal end,
- the placement structure comprising an offset fixture including a splash plate;
- and
- wherein the offset fixture is configured and arranged to hold the nozzle away from a structure for cutting and forming an offset distance between the nozzle and the structure;
- and
- a primary fluid inlet;
- a first valve fluidly coupled to the primary fluid inlet and configured to selectively regulate a primary fluid flow to one of a second valve inlet and a first output channel;
- and
- a second valve fluidly coupled to the second valve inlet and configured to selectively regulate primary fluid flow to a second output channel, wherein a channel geometry ratio between the first output channel and the second output channel defines a desired mixture ratio of an additive material with the primary fluid;
- and
- wherein the additive material includes one or both of an abrasive material and a foam.
A method of operating a fluid jet system comprising:
- providing a fluid jet assembly comprising:
- a lance including a lance barrel;
- a nozzle and a placement structure positioned coupled to the lance barrel at a distal end, the placement structure comprising an offset fixture including a splash plate;
- and
- wherein the offset fixture is configured and arranged to hold the nozzle away from a structure for cutting and forming an offset distance between the nozzle and the structure;
- and
- inputting a primary fluid into a primary fluid inlet of the fluid jet system;
- selectively regulating primary fluid flow to one of a second valve inlet and a first output channel using a first valve fluidly coupled to the primary fluid inlet;
- and
- selectively regulating primary fluid flow to a second output channel using a second valve fluidly coupled to the second valve inlet;
- and
- wherein a channel geometry ratio between the first output channel and the second output channel defines a desired mixture ratio of an additive material with the primary fluid;
- and
- wherein the additive material includes one or both of an abrasive material and a foam.
