DEVICE FOR SHAPING LIQUID JETS Russian patent published in 1995 - IPC

Abstract RU 2039275 C1

FIELD: mining. SUBSTANCE: device for shaping liquid jets has inlet and followed by pairs of conical and cylindrical branch pipes with radii decreasing in direction of liquid flow. Cylindrical branch pipe radii, lengths and tangents of taper angles of conical branch pipes in successive row of pairs are taken as geometric mean values. EFFECT: higher efficiency. 1 dwg
