GEAR FORMING LIQUID JETS Russian patent published in 2003 - IPC

FIELD: mining industry, hydraulic disintegration of rocks, coal, in particular. SUBSTANCE: in correspondence with invention volumes, radii and lengths of cylindrical branch pipes of gear, tangents of angles of conical branch pipes in successive row are implemented as geometric average values. Ratio of successive values are constant and equal: for volumes 1/2Φ, for radii ; for lengths 1/Φ, for tangents . Parameters of feeding branch pipe of gear are established by hydraulic characteristics of fed liquid: flow rate, initial velocity, supplied pressure, density, orifice coefficient, gravitational acceleration and number Φ, determining optical area of functioning of gear. EFFECT: optimized transmission of energy of jet, improved compactness of jet, increased coefficient of axial dynamic pressure. 1 dwg, 4 tbl
