FIELD: mining industry. ^ SUBSTANCE: stand can be used for experimental and research works related to study of resistance of pipelines and jet-forming assemblies. Hydraulic stand has main tank provided with nozzle, partition and stationary overflow pipe disposed inside tank, small measure tank for determining discharge of liquid, feed pipeline with valve, drain container under nozzle and under small measure tank, sucking-in pipeline, sump and pump. Stand is provided with additional measure tank and with additional drain container, both disposed at side face of main tank, with additional overflow pipe put on stationary overflow pipe for movement relatively the overflow pipe. Top part of additional overflow pipe is connected by rope with drum of manual winch and indicator of liquid level in the main tank through set of units. Main tank is divided by vertical partition to two parts. One part is connected to experimental pipeline provided with unions and glass piezometers. Experimental pipeline is made to have sections of rotations by 180°, narrowing and widening parts of pipeline. Experimental pipeline is provided with flow meter and lock disposed at its output. Nozzles and holed rings are disposed inside second part of main tank. ^ EFFECT: widened functional abilities. ^ 2 dwg |
