Device for defusing explosive charges by low pressure water jet cutting

摘要

The abrasive water jet circular cutter comprises a cutting head fitted with at least two canons (6) with parallel axes. The canons are mounted at different distances from the cutting head axis are arranged so that the gap in the siting of the canons relative to the cutting head axis has a value less than the thickness if the cutting line caused by the water jet (3). The canons each have a mixing chamber with a nozzle and an abrasive inlet (7). The distribution chamber (1) is connected to a pressurized water inlet (2).
