Automatic sandblasting machine

pressure

High pressure water blasting is done above and below water. It is a very controllable cleaning process. The pressure and flow can be adjusted for any cleaning job from removing surface dirt to stripping chipped paint or barnacles. High pressure cleaning is a flexible cleaning system also. It can be a portable, manual system with several guns to accommodate hard-to-get-at spots or a portable, automatic system with a specially designed oscillation nozzle arm to follow the whole contour of the ship’s hull. A high pressure pump is part of a truck-mounted, diesel-powered manual system. The manual system was chosen because it can adapt to the varied cleaning jobs of this contractor who refurbishes small pleasure craft, as well as, larger commercial vessels. The pump delivers 45 lpm and 320 Kg/cm2 of water to remove the most stubborn attackers of these ship hulls. When paint is removed, a rust inhibitor is used to prevent further rust development until the vessel is repainted. It has been found that high pressure blasting is much more effective than the old by-hand method with brushes and scrapers in removing the rhizoid of weed spores or barnacles. The old cleaning methods didn’t get at the root of the problem and the growth quickly reappeared. When the cleaning task is especially stubborn, this cleaning system can be quickly converted to a wet-sandblaster.
