Abstract

The invention discloses a high-voltage automatic-control aircraft fuel testbed oil supply system, which comprises a hydraulic subsystem, a pneumatic subsystem and a control system, wherein the hydraulic subsystem is used for providing fuel media with controllable pressure and temperatures; the pneumatic subsystem is used for providing air source power for the on-off action of a pneumatic ball valve and is used for discharging oil in a test element; and the control system is used for the control, the data collection and processing and the distribution protection of the hydraulic pressure systemand the pneumatic system. The system can be used for the fluid conveying of low-viscosity media, and the highest output pressure can be 15MPa. The system has a fuel medium temperature regulation function, carries out heat exchange with heat conduction oil through a heat exchanger to regulate the temperature of the fuel media.

Description

technical field [0001] The invention relates to a fuel supply system for a test bench, in particular to a high pressure, automatic control fuel supply system for an aviation fuel test bench. Background technique [0002] The fuel supply system of the aviation fuel test bench is a complete set of fuel supply system for the test of aviation fuel pump valves and other components. It requires remote automatic adjustment of medium temperature and pressure and has explosion-proof characteristics. At the same time, the system itself requires no leakage. [0003] Most of the existing fuel supply systems of various aviation fuel test benches use manual adjustment, which has low adjustment accuracy, low pressure, large system leakage, and lack of versatility. Contents of the invention [0004] The object of the present invention is to provide a high-pressure, automatic control aviation fuel test bed fuel supply system, which can realize fuel supply in a certain range of pressure, te...
