Abstract

The invention discloses an oil supply circuit for an engine test bench and a method for controlling the oil supply circuit. The oil supply circuit for the engine test bench, including the main fuel line and auxiliary oil line, the main fuel line is connected to the engine through the working nozzle, the input end of the auxiliary oil line is connected to the output end of the oil pump, and the oil injection motor is connected to the oil pump , the output end of the auxiliary oil circuit is connected to the main fuel line through the auxiliary oil line valve; The proportional reversing oil circuit of the fuel oil pressure, the proportional reversing oil circuit is connected to the main fuel pipeline through the proportional reversing valve; the fuel supply oil circuit also includes the PLC controller and the data acquisition system, the data acquisition system is connected to the PLC controller and sends to the PLC The controller feeds back the collected information. Realize the adjustment function of the fuel oil pressure of the auxiliary oil circuit.

Description

technical field [0001] The invention relates to the field of aero-engine ground tests, in particular to a fuel supply circuit for an engine test bench. In addition, the invention also relates to a method for controlling the fuel supply oil circuit of the engine test bench. Background technique [0002] The transmission system of the aero-engine is used to provide power for the aircraft, and the assessment test during the production and use of various types of engines is an important means to ensure the safety of the aircraft. Since it is difficult for the aircraft to perform these assessment tests during flight, these assessment tests need to be completed on the ground, which requires the use of an engine test bench. [0003] Since the complex aircraft hydraulic system cannot be installed on the ground test bench, the aero-engine transmission system on the ground or in flight is generally reproduced in a simulated manner. However, the aero-engine technical requirements sti...
