Предложена многоструйная абразивная головка для очистки/удаления поверхностей материалов иразделения/резки материалов струей жидкости, обогащенной твердыми абразивными частицамис равномерным профилем скорости и плотности, позволяющая увеличить мощность резки и использовать режущую струю с большей эффективностью.

The multi-jet abrasive head is for cleaning/removing material surfaces and cutting materials with a liquid jet enriched with solid abrasive particles with a proportional speed and density profile for increased cutting performance and more efficient use of the cutting beam. It contains a mixing chamber with inlets of gas mixture and an abrasive connected to the abrasive nozzle, and contains at least one set of at least two liquid nozzles around the tool axis, where each fluid nozzle ends in a common channel connected to the mixing chamber, and the axis of the liquid nozzle forms an angle of 0.5° to 45° with the tool axis, the liquid nozzles in the set are equidistant from the outlet of the abrasive nozzle at the same angle between the axis of the fluid nozzle and the tool axis, are rotationally symmetrical about the tool axis or opposite to each other, with a common intersection with the axes of the liquid nozzles and the tool axis in the common channel before entering the mixing chamber in the flow direction.
