Abstract
Использование: предотвращение кавитации в центробежных насосах. Сущность изобретени : во входном патрубке 1 размещен неподвижный обтекатель 3, с которым соединена конфузорна кольцева вставка 5, охватывающа установленную на обтекателе 3 с возможностью поворота относительно продольной оси насоса решетку радиальных лопастей 4, которые выполнены из тонколистового упругого материала с продольными гофрами 6, расшир ющимис в радиальном направлении от обтекател 3 к периферии. 2 ил.Usage: prevention of cavitation in centrifugal pumps. SUMMARY OF THE INVENTION: A stationary fairing 3 is placed in the inlet pipe 1, to which a confuser annular insert 5 is connected, covering a lattice of radial blades 4 mounted on the fairing 3 with the possibility of rotation relative to the longitudinal axis of the pump, which are made of thin-sheet elastic material with longitudinal corrugations 6 expanding radially from the fairing 3 to the periphery. 2 ill.
