Abstract

Appareil pour la détermination thermodynamique du rendement de dispositifs hydrostatiques. Cet appareil comprend un raccord 6 relié à un conduit 2 des hautes pressions, un raccord 9 relié à un conduit 4 des basses pressions ou à un réservoir 5, et des dispositifs 7 et 8 de modification d'état d'un liquide respectivement à entropie et à enthalpie constante. Des détecteurs de température A, B et C sont groupés selon des montages différentiels corresponant à chacun des dispositifs 7 et 8 et dont les sorties sont reliées à un circuit électronique comprenant des amplificateurs 16 et 17 des différences de température mesurées, un diviseur 18 et un dispositif d'affichage 19 du rendement. Application à la détermination du rendement global de pompes, de moteurs et de dispositifs de transmission hydrostatiques.Apparatus for the thermodynamic determination of the efficiency of hydrostatic devices. This apparatus comprises a connector 6 connected to a high pressure duct 2, a connector 9 connected to a low pressure duct 4 or to a reservoir 5, and devices 7 and 8 for modifying the state of a liquid respectively at entropy. and at constant enthalpy. Temperature detectors A, B and C are grouped according to differential arrangements corresponding to each of the devices 7 and 8 and whose outputs are connected to an electronic circuit comprising amplifiers 16 and 17 for the measured temperature differences, a divider 18 and a performance display device 19. Application to the determination of the overall efficiency of pumps, motors and hydrostatic transmission devices.
