HYDRAULIC WEIGHTING DEVICE FOR A BOREHOLD HYDRO UNIT

摘要

1. A hydraulic weighing device of a downhole hydraulic unit, including an airlift suction tip 1 with a hydraulic monitor 3 and a protective receiving grate 6, characterized in that, in order to increase work efficiency, this device is equipped with a separate long-barrel vertically movable pressure pipe 2 displaced along the inner side surface of the airlift pulp line 1, and a hydromonitor 3, hydro-weighting the unconsolidated ore. 2. A hydraulic weighing device of a downhole hydraulic unit according to claim 1, characterized in that it is a hydraulic monitor having a jet-forming nozzle and a box-shaped reflector 4 fixed along the length of the jet, combined into a single integral hydrodynamic hydraulic weighing device of a downhole hydraulic unit. 3. A hydraulic weighing device of a downhole hydraulic unit according to claim 2, characterized in that the box-shaped reflector 4 forms a flat high-speed reflected jet. A hydraulic weighing device of a downhole hydraulic unit according to claim 3, characterized in that the reflected plane jet is a one-way upward flow, inclined from the axis of formation of the suction flow, by a solid hydraulic flow in the airlift suction plane, which creates significant reactive radial forces for rigid fixation of the high-pressure head of the hydraulic monitor at the inner side surface pulp line of the hydraulic unit. 5. The hydraulic weighing device of the borehole hydraulic unit according to claim 3, characterized in that the bottom of the box-shaped reflector 4 has openings - hydromonitor nozzles 5 for additional decompression of the incoherent ore mass at the bottom of the bottom, and thereby providing
