An abrasive blasting system that includes a blast hose; and a deadman assembly operably coupled therewith for controlling discharge out of the blast hose. The deadman assembly has a position of either a signal-flow or a no-flow position. When engaged to the signal-flow position, a burst or pulse of purge air is transferred to a mixer via a water injection conduit.

An abrasive water jet cutting machine including pumping means, which can be fluidically connected to a water source, for the generation of a pressurized water flow; a cutting head, forming a mixing chamber and a focusing nozzle; a dispensing system of powdered abrasive material, including a tank containing powdered abrasive material, a feeding pipe, fluidically connecting the tank to the mixing chamber of the cutting head, a dispenser, which dispenses the powdered abrasive material contained in the tank into the mixing chamber by means of the feeding pipe; wherein the pressurized water flow originating from the pumping means is conveyed into the mixing chamber of the cutting head where the pressure energy of the pressurized water flow is converted into kinetic energy so as to form a water jet; wherein the cutting head mixes, in the mixing chamber, the abrasive material with the water jet forming a water-abrasive material mixture jet, and the cutting head dispenses the water-abrasive material mixture jet by means of the focusing nozzle; wherein the powdered abrasive material contained in the tank is homogeneously dispersed in suspension in a gelatinous water-based fluid; and wherein the mass ratio of the dispersed powdered abrasive material to the gelatinous water-based fluid is from 1.0 to 3.5.

A water-abrasive suspension cutting facility includes a high-pressure source (3) for providing (301) water at a high pressure, a high-pressure conduit (5) which is connected to the high-pressure source (3), a pressure tank for providing (303) a water-abrasive agent suspension (13) which is at a high pressure, a lock chamber (21) which is designed to temporarily be at a high pressure and temporarily at a low pressure, and a filling valve (23) for filling (311) the lock chamber when this is at a low pressure. A pump (31) at the suction side is fluid-connected to the lock chamber in a manner capable of being shut off, in a manner such that given high pressure in the lock chamber (21) the pump is shut off from this and given low pressure in the lock chamber (21) the pump is in the position of sucking an abrasive agent suspension through the filling valve (23) into the lock chamber (21).

The present disclosure discloses an abrasive water jet full-section cutting type cutter head and application devices. The cutter head includes a cutter head body and a rotor eccentrically arranged on a working surface of the cutter head body. The rotor revolves with the cutter head body and also rotates about its own axis. At least one first nozzle is arranged on an edge of a working surface of the rotor. At least one group of second nozzles and at least one third nozzle are arranged on the working surface of the cutter head body, and the second nozzles and the third nozzle cooperate during the rotation of the cutter head body and the rotor, then a material to be cut is cut into a plurality of concentric rings, and the first nozzle cuts off the ring material to form fragments.

An abrasive head with clean gas infeed for cleaning/removing material surfaces and splitting/cutting materials by a liquid beam enriched with solid abrasive particles to extend the tool lifetime by eliminating damage to the liquid jet's aperture by the abrasive, avoid degrading the abrasive inside the tool and increase the cutting power and flow efficiency.
