THE ELIMINATING APPARATUS PAINT ON FACE BY MIXING INJECTION HIGH PRESSURE WATER AND SAND

摘要

A device for processing a painting surface by mixed-jetting high-pressure water and abrasives is provided to further increase jet pressure through a jet nozzle of a gun. A water jet machine(1) converts flowing water into high-pressure water. An abrasive reservoir(5) stores abrasives such as sands. A gun(3) jets the high-pressure water and abrasives in a state of mixing the high-pressure water and abrasives. The water jet machine supplies the high-pressure water from an auxiliary tank(11) through a high-pressure hose(2) to the gun by operating a pump(12) which is operated by motive power of an electric motor(13) driving in electric power of a power supply portion(15). Wheels(10a) are installed on a trailer for freely moving the water jet machine.
