Ground test structure of pressure refueling system

Abstract

The invention relates to the field of machinery, and provides a ground test structure for a pressure refueling system, including a control pipeline, a refueling joint, a refueling pipeline, a vacuum valve, an electric fuel switch, a nozzle, a metal fuel tank, a float valve, and a full oil level signal device , warning oil level signal device, overflow pipe, overflow valve, refueling control switch, indicator light, control box and electrical connecting wire, utilize the ground test structure of the pressure refueling system of the present invention to carry out the ground of the pressure refueling system in advance before the on-board test The simulation test and ground test find problems and solve them in time, and improve the design, which can greatly reduce the risk of the on-board test and improve the success rate of the on-board test. The invention is suitable for aircraft design test.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a ground test structure of a pressure refueling system. Background technique [0002] The pressure refueling test is a key link in the design of the pressure refueling system. The purpose of the test is to verify whether the function of the pressure refueling system can meet the design requirements. Usually, the pressure refueling system test of the aircraft is carried out directly on the aircraft, but this kind of test There are great risks in this method. On the one hand, due to the fast refueling speed of pressure refueling, the risk of pressure refueling is relatively high. Once the system fails and the fuel tank is over-pressurized, the fuel tank will be ruptured due to excessive pressure; on the other hand, when the aircraft is assembled It is better to carry out the pressure refueling test again. It is more difficult to solve the problem after it occurs, and it will take a long time...
