NONREACTIVE HYDRAULIC GIANT FOR CLEANING OF SURFACES Russian patent published in 2008 - IPC B63B59/06 B08B3/02 

FIELD: technological processes.

SUBSTANCE: hydraulic giant is related to devices for hydrodynamic treatment of surfaces performed in liquid or gas phase, and may be used for cleaning of hulls, submerged structures, hydrotechnical facilities and other objects from contact deposition of different genesis. Nonreactive hydraulic giant for cleaning of surfaces contains case-handle with channels of working fluid supply, shaft, high discharge working nozzle, auxiliary nozzle for balancing of reactive force of working jet, controller for working fluid flow and hose that connects inlet channel of case-handle with manifold of high pressure source. Auxiliary nozzle is equipped with supply tube, aligned with working nozzle and installed in protective jacket. Jacket is arranged in the form of cylindrical tube and is equipped with reflector on one end arranged in the form of hemisphere, concave side of which faces auxiliary jet. Area of auxiliary nozzle section is selected as twice less than area of working nozzle section.

EFFECT: simplification of design, higher convenience of operation and reduction of power inputs in operation due to reduction of working fluid flow used for balancing of reactive force of working jet.
