FIELD: testing hydraulic equipment. SUBSTANCE: proposed technique includes pumping of liquid working medium with preset hydrodynamic parameters through equipment under test by continuously passing working medium from one service/intake tank to other one; for the purpose desired pressure drop is built up between them and working medium parameters are measured at equipment under test; pressure drop between service/intake tanks is built up by heating one of these tanks filled with liquid working medium and sealed in advance to temperature corresponding to pressure of saturated working- medium vapors exceeding preset pressure of working medium in equipment under test by pressure drop in supply path at the same time cooling down other tank to temperature corresponding to pressure of saturated working-medium vapors in this tank to ensure desired flow of working medium through equipment under test. EFFECT: enhanced reliability and validity of test results. 1 dwg
