Description

Be used for abluent high-pressure water rust cleaning device of ship Technical Field The utility model belongs to the field of high-pressure water rust removal, and particularly relates to a high-pressure water rust removal device for ship cleaning. Background The high-pressure water rust removing method is a rust removing method for removing rust on the surface of metal by utilizing high-pressure water flow. The water is pressurized to a certain pressure and then sprayed onto the metal surface through the nozzle, so that the water flow impacts and takes away the rust and dirt on the surface. Less damage to the metal surface, and is an environment-friendly and pollution-free rust removal mode. The ships navigate in the ocean for a long time, are generally easily influenced by the high hydrochloric acid and the alkalinity of the seawater, are easy to rust, and need to be treated in time to avoid influencing navigation and even reduce the service life of the ships.
