DEVICE FOR TESTING INTERVAL LEAKAGE OF HYDROJET Russian patent published in 1994 - IPC

FIELD: mechanical engineering; determination of service conditions of hydrojets without their disassembly. SUBSTANCE: device has pressure source, hydraulic line for discharge of leaks, measuring vessel with bottom, vertical side walls made of transparent material, scale made on side walls and drain channel, locking member with inlet and outlet channels communicated, respectively, with hydraulic line and measuring vessel nozzle fitted on outlet channel end. Axis of outlet channel is located at angle of 60-70 deg. to bottom horizontal plane. Working fluid incoming through outlet channel to nozzle form jet whose height is indicative of serviceability of hydrojet. EFFECT: higher efficiency. 3 cl, 3 dwg, 1 tbl
