Installation for stand studies
of discharge performance of hydraulic resistance

(It is covered by RU patent № 2164667)

The invention can be used to compute the discharge performance of different convergent devices: diaphragms, throttles, nozzles, and jets. The installation contains a discharge tank with a level gage mounted in it and a drainage tank.
They are connected with working and overflow liquid manifolds and with two manifolds for gas feed and discharge. Every manifold includes an electromagnetic valve. The tanks are equipped with pressure transducers and jackets for thermal conditioning. The first heat exchanger, filter, flow meter, the second heat exchanger and a tested element with temperature transducers at the inlet and outlet and pressure drop transducer are mounted in the working manifold.
The pipelines of the working manifold at the section from the first heat exchanger to the tested element have a thermal insulation. Computer controls the electromagnetic valves and cocks. The pressure and temperature transducer indications are recorded. The installation provides a possibility to studying the influence of temperature and kind of the working fluid on the discharge performance.
