FIELD: physics.
SUBSTANCE: stand includes water catch pit with cone bottom, feeding and discharge pipes with stopcocks, and water-distributing pipe with removable spray units. The stand is equipped with insulated reservoir, pump, filtre, pressure regulator, flexible hose, telescopic boom, measuring cylinders, controlling pressure-gauges, thermometre and areometre mounted in sequence in hydraulic network. Insulated reservoir mounted behind a stopcock has admission valve providing air access, release valve, water measuring device, suspension, drainage and water discharge valve. Filtre for extraction of suspensions and mineral trash is mounted between the pump and pressure regulator via a valve to drainage network. Controlling pressure-gauges are installed at the input and output of the pressure regulator. The filtre has a pipe for recirculation flow feed. A flexible irrigation pipeline with built-in trickles under test is fixed by cramps on the telescopic boom as a water-distribution pipe. The said telescopic boom with moving elements in its cavity is mounted by a slide bearing at an axis. The axis is placed in the upper part of a post. The post basis is counterbalanced. The counterbalanced post is placed in the water catch pit with cone bottom. The said telescopic boom has kinematical connection by a diagonal brace to the post. The diagonal brace enables boom tilt at maintained angles to the vertical symmetry axis of the post. The flexible irrigation pipeline with built-in trickles under test has hydraulic connection to the filtre by a T-joint and flexible hose. The T-joint is installed in direct vicinity of rotation axis of the telescopic boom. A measuring cylinder is mounted on pendulum suspension under each trickle of the tested flexible irrigation pipeline. The pendulum suspension with measuring cylinder can dump water into the water catch pit with cone bottom.
EFFECT: possibility to obtain irrigation water flow characteristics for each trickle in the irrigation pipeline cavity.
