摘要： A tool for cleaning electrically energized equipment. The tool has an elongate tubular body having a fluid input at a first end and a nozzle adapter at a second end. A first end of a nozzle is securable to the nozzle adapter. A bore extends through the body and terminates at a fluid output at a second end of the nozzle. The bore through the body, the fluid input, and the nozzle adapter has a generally circular cross-section. The fluid input has a fluid input transition to reduce the cross-sectional diameter of the bore therethrough in a direction toward the tubular body. The bore through the nozzle has a transition to alter the cross-sectional shape of the bore therethrough from generally circular to generally rectangular at the fluid output. Pressurized cleaning fluid delivered to the fluid input passes through the fluid output in a stream having a generally rectangular cross-section.

摘要： An abrasive water jet nozzle for strengthening, including a chamber, providing a mixing space; and a strengthening mixing assembly, providing a strengthening mixing of water with an abrasive entering the chamber, wherein the strengthening mixing assembly includes a fluid passage and a water stopper block, wherein the water stopper block is located at an eccentric position on one side of the chamber, and an outlet of the fluid passage faces the water stopper block. The provided abrasive water jet nozzle is capable of fully mixing high speed water with the abrasive particles after the high speed water entering the mixing chamber, so as to ensure the uniformity of the strengthening effect, and the formed abrasive water jet is a large circular fan-shaped jet, which can greatly improve the strengthening quality of the abrasive water jet.

摘要： A focusing tube is configured to focus a high-pressure liquid jet containing abrasive particles. The focusing tube has a focusing duct portion and an exit opening for the free discharge of the liquid jet from the focusing duct portion. A center point of the discharge opening coincides with the longitudinal axis of the focusing duct portion. The focusing duct portion is delimited by a liquid-impermeable channel wall, extends from the discharge opening at a focusing taper angle and is tapered toward the discharge opening. The focusing taper angle lies in a range from 0.05° to 1°. This allows the service life of the focusing tube to be increased in a way that is simple in terms of design.
