DEVICE FOR WATERJET CUTTING WITH ABRASIVE

摘要

The invention relates to an abrasive water jet cutting system comprising a high-pressure source (2) which provides high-pressure water, an outlet nozzle (8) and a high-pressure line (6) connecting the high-pressure source (2) to the outlet nozzle. The system further comprises an abrasive supply device (14) connected to the high-pressure line (6), said abrasive supply device (14) having a sluice with at least one chamber (40, 40'), said chamber (40, 40') having at least one first closable opening (50, 50') and being alternately openable towards the high-pressure line (6) and an abrasive supply unit.
