Engine laminate restrictor test board

Abstract

The invention relates to an engine laminate restrictor test board. An automatic measurement and control system and a laminate restrictor test system are installed inside a test board body. The automatic measurement and control system comprises a panel industrial personal computer, a frequency converter and a PLC which is communicated with the panel industrial personal computer. An oil tank and an anti-detonation oil pump set which is connected with the oil tank are installed inside the test board body on the lower portion of the test board. The PLC is electrically connected with a frequency conversion motor of the anti-detonation oil pump set. The laminate restrictor test system is connected with the anti-detonation oil pump set through an oil delivery pipeline. An inlet pipeline of the laminate restrictor test system is provided with a laminate restrictor inlet pressure gauge and a laminate restrictor inlet pressure transmitter which is electrically connected with the PLC. The oil tank, the anti-detonation oil pump set, the automatic measurement and control system and the laminate restrictor test system are distributed on the test board, automization of a laminate restrictor test is achieved, and the problem that a performance test cannot be carried out on a laminate restrictor in an engine fuel system adjusting device is solved.

Description

technical field [0001] The invention relates to a test bench for an engine fuel system, in particular to a test bench for testing the performance of an engine laminate throttle. Background technique [0002] The engine fuel system is used to supply and regulate the fuel required by the engine under given various operating states and flight conditions. Engine speed, jet temperature, starting and acceleration performance, etc., all need to be adjusted through the laminate throttle in the fuel system adjustment device. Therefore, the performance of the laminate throttle has a major impact on the performance of the engine and the reliability of the work. [0003] There are more laminate restrictors in the engine fuel system adjustment device. Taking the WP-13 series turbojet engine as an example, there are 6 laminate restrictors in the main fuel system of the engine, and these laminate restrictors are the main adjustment elements of the engine's starting time, half acceleratio...

AI Technical Summary

Problems solved by technology

Whether the performance of the laminated restrictor in the engine is normal, whether the performance of the laminated restrictor after cleaning is up to the standard, and whether the technical state of the laminated restrictor in stock meets the requirements before installation can not be completed on-site test, and can only be returned. Factory calibration, and this will waste a lot of time and financial resources, affecting the troubleshooting and normal use of the engine
