Область применения: в качестве технологического оборудования для очистки отложений на днище судна, подводных трубопроводах и других подводных гидротехнических сооружениях. Сущность изобретения: насадок-кавитатор имеет проточный канал с резко расширяющейся полостью, в которой генерируются кавитационные пузырьки. В канале соосно установлено центральное тело, которое с корпусом образует зазор постоянного сечения. Центральное тело имеет тупой торец на входе в диффузор, который позволяет сфокусировать кавитационные пузырьки по всему сечению потока жидкости, истекающему из диффузора.Scope: as technological equipment for cleaning deposits on the bottom of the vessel, underwater pipelines and other underwater hydraulic structures. The inventive nozzle-cavitator has a flow channel with a sharply expanding cavity in which cavitation bubbles are generated. A central body is coaxially mounted in the channel, which with the housing forms a gap of constant cross section. The central body has a blunt end at the entrance to the diffuser, which allows the cavitation bubbles to be focused over the entire cross section of the fluid flow emanating from the diffuser.
