Abstract
An abrasive-liquid jet cutting head comprising at least one mixing stage; a first mixing chamber arranged to accept a coherent high pressure liquid from an orifice and flow of accelerated abrasive particles from an abrasive feed tube and produce a pressurized slurry-like flow that enters a nozzle; wherein a nozzle to orifice ratio is in a range of about 1.2:1 to 2.49:1 wherein nozzle opening size to orifice opening size is 1.2 to 2.49 times larger in size.
Claims9
A abrasive-liquid jet cutting head comprising:
- an orifice aligned to a nozzle;
- at least one mixing stage;
- a first mixing chamber arranged to accept a coherent high pressure liquid from said orifice and flow of accelerated abrasive particles from an abrasive feed tube and deliver said liquid and said abrasive into an inlet of said nozzle;
- an abrasive liquid jet produced by said nozzle wherein a nozzle to orifice ratio is established in a range of 1.2:1 to 2.49:1 wherein nozzle opening size to orifice opening size is 1.2 to 2.49 times larger in size.
A method for producing a high velocity abrasive liquid jet utilizing a cutting head with an orifice aligned to a nozzle with a defined nozzle to orifice ratio of 1.2:1 to 2.49:1, being that the nozzle is 1.2 to 2.49 times larger in size than the orifice.
