Abstract

The invention discloses a mechanical performance test device of an inert gas closed-cycle radial impeller based on a turbocharger structure, comprising: an inert gas storage tank, a pressure stabilizer box, a turbocharger, a tester, a motor, and a cooler , heater, regenerator, throttle valve, anti-surge valve, bypass valve, temperature and pressure probe, vacuum pump. Take the turbocharger as the basic structure, replace its original centripetal turbine or centrifugal compressor with the tester, and use the centrifugal compressor of the turbocharger as the power consumption device, or use the centrifugal compressor of the turbocharger as the power consumption device. Turbine as power plant. The tester, heater, regenerator and cooler form a closed loop with inert gas as the working fluid through pipelines and valves, and the closed loop utilization of inert gas is realized by cooperatively controlling multiple test equipment. The invention has the remarkable features of ingenious and reasonable structure design, resource saving and the like, and is easy to popularize and apply on a large scale.

Description

technical field [0001] The invention belongs to the technical field of engine performance testing, and relates to a radial impeller mechanical performance testing device, in particular to an inert gas closed-circulation radial impeller mechanical performance testing device based on a turbocharger structure. Background technique [0002] At present, a variety of inert gases, including helium, argon, xenon and their mixtures, are used as substitutes for air, and are increasingly widely used in various closed and semi-closed Brayton cycle systems. As one of the key components of the energy conversion system, the inert gas turbomachine usually works under various working conditions, and its aerodynamic performance directly affects the efficiency of the entire system. Therefore, it is very necessary to obtain the aerodynamic characteristic data of the turbomachinery under all working conditions for the safe and reliable operation of the system. Theoretical analysis and numerical...
