An aircraft fuel system detection test bench

Abstract

The invention discloses an aircraft fuel system detection test bench, which belongs to the field of aircraft fuel systems. The lifting frame at the center of the bottom of the operating platform, the top center of the operating platform is provided with a material feeding port corresponding to the top of the lifting frame, the inner wall of the lifting frame is slid and connected with a lifting plate along the vertical direction, the lifting frame The top of the lifting plate is rotatably connected with an oil pump table, and three sets of provoking grooves are opened on the top of the oil pump table; the clamping mechanism includes two guide rails symmetrically arranged on the front side and the rear side of the top of the console, and And along the extension direction of the guide rail, there are sliding mechanisms distributed on both sides of the feeding port. The invention facilitates the transfer of the aircraft oil pump to the workbench, and is convenient for fixing and dismounting, and is convenient for all-round inspection of the oil pump.

Description

technical field [0001] The invention relates to the technical field of aircraft fuel systems, and more specifically relates to an aircraft fuel system detection test bench. Background technique [0002] The function of the aircraft fuel system is to store fuel, and to ensure that under any specified state (such as various flight altitudes, flight attitudes), it can continuously supply fuel to the engine according to the pressure and flow required by the engine. In addition, the fuel system It can also complete additional functions such as cooling other systems on the aircraft, balancing the aircraft, and keeping the center of gravity of the aircraft within the specified range. The requirements for the fuel system are: reliable operation, long life, fire safety, light weight, small size, and structure Simple, convenient maintenance and repair, precise control and good production process. [0003] In the aircraft fuel system, the most important part is the fuel pump. During t...

Problems solved by technology

[0003] In the aircraft fuel system, the most important part is the fuel pump. During the inspection and test of the aircraft fuel pump, due to the special shape of the fuel pump, the pump must be closely attached to the joint surface during the test, and the current clamping The test bench is fixed by bolts. Because the aircraft fuel pump itself is relatively large, it is difficult to transport it to the test bench, and it is also difficult to turn over the fuel pump. It is not convenient to detect all directions of the fuel pump. At the same time, the efficiency of bolt fixing is relatively low. Low, very inconvenient to disassemble, low degree of automation
