Abrasive water jet nozzle and abrasive water jet machine |
摘要 |
<p>Provided is an abrasive water jet nozzle (1) comprising a mixing chamber (3) for absorbing the abrasives (G) therein with air through a supply port (31) ; a water nozzle (4) ; a mixing nozzle (5) disposed on a downstream side against the water nozzle, to mix the abrasives in a water jet (WJ) jetted out of the water nozzle, and to jet the water jet (AW) mixed with the abrasives into the mixing chamber out of a through hole (51) of the mixing nozzle; and an abrasive nozzle (6) disposed on a downstream side against the mixing nozzle, to introduce the water jet thereinto, and to jet an abrasive water jet (AWJ). A diameter (D3) of the through hole of the mixing nozzle is larger than a diameter (D1) of the water nozzle so that the abrasives in the mixing chamber are absorbed together with air in a clearance (´1) formed between the through hole (51) and the water jet passing through the through hole to mix the abrasives in the water jet in the through hole.</p> |
