METHOD FOR HYDROABRASIVE CLEANING OF SURFACE

摘要

in building, machine engineering, ship building for cleaning surfaces of articles. SUBSTANCE: method comprises steps of cleaning by jet of abrasive material directed by means of ejector onto cleaned surface; using sand as abrasive material; continuously mixing sand with water in partition-type mixer and feeding pulp to ejector by means of centrifugal pump mounted in line for supplying pulp ( mixture of sand and water) to ejector; feeding to ejector water under pressure 25-40 MPa. EFFECT: enhanced efficiency of abrasive cleaning of surfaces of different materials. 1 cl, 2 dwg
